Snowstorm (in mid April?)

A snowstorm in April?It seems like winter just doesn’t want to let go this spring.  I’ve actually seen snow falling more than half the days this past week.  It hasn’t been terribly warm this week and the snow that has been sweeping across the country from Colorado to the Northeast arived this afternoon.  I couldn’t get a picture because it’s now dark, but there is an inch or two on the ground now and it hasn’t stopped yet.  The kids even wanted go go sledding (there is actually enough for that), but mom vetoed that idea in favor of bed time.

Needless to say nothing has gotten done beekeeping wise.  Last year this time I was making up mating nucs and putting out the first batch of queens.  This year it’s simply too cold to begin.  The shipment of package bees was also delayed due to the weather.  I’m eager to get started, but it was probably a good thing.  Hopefully this next week will be more promising.  It doesn’t look like  a warm forcast, still below normal, but should get into the 50’s.  The package bees should be here late this coming week, and with luck it will be warm enough to start grafting and inspecting hives.  I expect to find a few more hives that were lost in the past couple weeks with the cold weather and snow, but only a few.  Still, it could push our final loss to 60%, a full 6 times our normal loss.

Where Did April Go?

Snow reportWhat is wrong with this picture?  April and today at 41 degrees, was the warmest day in the past 6.  4 of those days I’ve awoke to find snow on the ground.  (I had a picture of hives in the snow take just yesterday, but it was on a new camera phone and I just couldn’t get it working right). 

Delays:  Was a beautiful 2 weeks before this past week.  highs in the 60’s and 70’s with lows only in the upper 40’s.  But as of last week everyting was put on hold.    We were to begin grafting last week (can’t do that when the high’s barely got to freezing), and the package bees that were to be delivered were delayed due to bad weather in the Rocky Mountains.  They didn’t want to chance them getting delayed due to road closings.   We’ll have to keep a close watch on our weather, it’s finally starting to look up this weekend (at least I hope this is the last snow I see this season).

Chilled Brood:  The couple of warm weeks did give the hives a much needed boost.  They were bringing in nectar and pollen with no end in sight and the willows had just bloomed and were literally buzzing just before the cold front blew in.  Unfortunately though I think I’ll find a lot of chilled brood in the hives once it warms up.  In the warm spell they simply started raising more brood than they could keep warm once it got cold again.  The scene in my observation hive paints a sad picture.  Even with the hive indoors, the bees weren’t able to keep 1/4 to 1/3 of the brood warm and there is noticeably stressed and decaying brood where they weren’t able to cover it.  The hives still should recover, they’ll just have lost another week or so.

Winter Losses

As I wrote the previous post I know losses were high.  But until I got into the rest of the yards, I didn’t know how high. At home they weren’t too bad, but some of the out yards got hit hard.  It’s nothing like anything I’ve seen before. Everyone I’ve talked to in the state are seeing losses of 50-80%, and unfortunately mine are no different.  I got a good chance to look at the hives this week in the warm spell and many of the remaining hives are week.  I expect to loose a few more before spring really hits, but most of the remaining should survive, but won’t be ready to split for nucs come April.  The only good thing is that most of my breeding stock (Instrumentally Inseminated queens) made it.

I’ve spent the past few days trying to decide how to proceed from here.  After long consideration and several sleepless nights, I’ve decided to scale back the queen rearing significantly this year to rebuild and concentrate on the breeding stock.  I simply don’t have the bees for mating nucs and financially bringing in outside hives just isn’t an option.  It’s depression and I just want to go outside and scream, but I’ve got to deal with the hand I have.

Some Observations:

I haven’t spent much time looking at the dead outs yet as I’ve been concentrating on the live ones.   I can’t say if it’s this CCD that is all over the news.  Only one hive ‘dissapeared’ as described, and that was back in October.  There were also only a few that outright starved (we had a very poor honey year and I ended up doing a lot of feeding in the fall).  Most so far seem to have smaller than normal clusters and appear to have starved surrounded by honey.  Possibly caught in this last cold spell we had.  I’ve talked to several people who’s hives were alive before the cold snap,  but then lost around half.  My hunch is that it is due to lack on nutrition or nutritional stress.  They seem to have little pollen and haven’t begin raising brood like they normally would.  Hives in the latter part of last year had trouble building up as well.  Some others have noticed that bees going on cleansing flights over the winter (on warmer days) didn’t seem to return.  I also saw a lot of dysentery, someting I usually don’t see in more than 1 or 2 hives at most.  All this (and more) makes me lean towards a pollen deficency as it reduces overwintering success, health, increases sensitivity to pesticides (herbicides, etc.).

Overall, my the bees at home did the best (I did open feed pollen substitute in the fall), and The II queens did well.  The 2 yards that had the larger losses last year (though it wasn’t high), were nearly decimated this year.

The Season Begins

Large drifts still have not yet melted, but it’s finally above freezing with temperatures near 50 for the past few days.  The latter part of last week was spent mixing up sugar syrup and feeding hives to get them moving and prevent starvation.  I also put out dry pollen substitue to keep them busy until the maples start blooming.  Later this week I’ll be adding pollen patties to the hive to really get them producing brood.

Winter losses were high.  Much of it was expected though after a very poor honey crop last year and a poor fall, resulting in hives that were light in fall.  Much of it seems to be due to starvation in spite of our fall feeding attempt, in hindsight we probably should have fed earlier, longer and more of the hives.  There also seemed to be quite a few that died of local starvation where the cluster got caught away from the honey in a cold spell.  In these cases the cluster looked smaller than expected.  Those hives that were fed in general did much better.  It will take some work to get built back up again.  On the plus side, most of the breeder queens made it.

Of course the question I am constantly asked now due to all the media coverage is ‘do your bees have CCD’ or similar question.  I really can’t answer that one.  Other than defining what some symptoms are, no one knows what it really is.  Losses are up statewide, with most everyone I’ved talked to seeing 50-80% losses (commercial and hobbiest alike).  A lot of it is being blamed on CCD, but I think it’s a bit of a ‘desease of the day’ syndrome.  I did see one hive in October that looks exactly like CCD, but most of the deadouts do not.  Are the small clusters that died due to a milder case of CCD?  Until someone figures out exactly what it is, I don’t know.  Apparently CCD (or something similar) has been documented in this country as early as 1915 (according to James Tew), with occurences in other countries.  But is always seemed to go away as quickly as it came, and no one figured out why then either.  Hopefully it will do the same now.

Here’s hoping for a good year….

Keeping Warm – with Corn

The warm spell is definately over with highs now in the 20’s and the bees are nicely tucked away in their hives. The front that brought an end to the heat wave came in with a roar with wind gusts I believe near 50 mph. I ended up having to check all my hives and replace telescoping covers which had blown off the hives and landed 20 feet away in some cases. As I was coming home from work I wasn’t dressed appropriately and between the standing water soaking my shoes and gale force winds below freezing, it wasn’t pleasent.Quadra-Fire Sante Fe

So it made for a good weekend to sit by the fire and do on overdue computer work. We actually installed a Quadra-Fire pellet and corn stove in both the home and at my wife’s business to help cut down on fuel costs (our furnace runs on fuel oil). Of course it helps that we live in an area where corn is plentiful and we can buy it directly from the farmer.
Overall my wife and I both love the stone. It isn’t enough to heat the whole house; mainly because the heat isn’t distributed well because of the floor plan. It has automatic start and can be hooked to a thermostat so it can be left on when you aren’t at home. It can use a direct vent strait out the wall with a 3″ID double wall pipe making installation a breese (and you get to play with power tools!). It has very minimal power requirements to run the blowers and electric start so it can be plugged into any 120v outlet. It generates a bit of smoke when starting, but is virtuly smokeless once started and the exaust is cool enough to put your hand in. It does need daily cleaning (especially if you run corn or a mix of corn and pellets that is required for auto starting), but it typically only takes about a minute and has several pulls built in to clean the various parts. The top and sides get warm, but not too hot to touch. In fact several of our cats love sleeping on it while it is on. Overall it is quite well thought out and we wouldn’t trade it in, however:

I do have a few complaints and suggestions:

  1. The corners of the soot drawer (underneath the unit to catch and remove the ashes) are not tight or sealed. This means soot leaks out and forms a small pile at the botton front corners of the unit. I’m not sure why the corners couldn’t be welded or simply sealed with a heat resistant sealant as several parts inside the unit already are. (It just seems cheap and a big oversight in an otherwise nicely designed stove).
  2. The unit comes with a can of paint to touch up scraches and a small scraper to break up clinkers and scrape the fire pot. It’s a small thing, but very nice to have included. However, I’m surprised Quadra-Fire stops there and doesn’t also include a 99 cent cheap 1″ paint brush to clean the soot. (I bought one myself).
  3. It does come with a thermostat, but it’s a cheap bimetal mechanical model. I would have appreciated a cheap digital thermostat with a stove that costs a couple thousand dollars. I purchased one locally for $20 retail.
  4. The 3 speeds is a very nice feature and a big selling point in my opinion. However, I was surprised that the only way to control the speeds is via a switch in the back of the unit. There are no contacts available so that it could be controlled by a remote switch or even a dual stage thermostat that could turn the speed up when the room is colder. Such thermostats are readily available (typically for heat pumps) but could be used with the stove if only the connections were available. The switch that is built in unfortunately is part of a sealed speed control unit with a ‘warrantee void if removed’ seal. So unless one wants to void the warrantee, you cant use a remote switch or multiple-state thermostat.
  5. The speed of the feed mechanism is controlled by a plate inside the hopper where the fuel is. It’s located such that it’s nearly on the bottom so the hopper has to be mostly empty to adjust the feed which is inconvenient. We also found that with our two units, the plate had to be adjusted significantly different for the two units to work properly. On the stove at home it needed to be adjusted all the way down or the feed rate was too high (the fire was too high), yet the same model we have at work wouldn’t maintain a fire at all unless the plate was raised to increase the feed rate. It seems to me that the feed rate between units with feed control plates set identically don’t end up with the same feed rate. It would be nice if the rate could be controlled electronically by a simple knob located inside the unit. It would also be good if there was a feed rate ajust for each of the 3 speeds as we have found that a different feed rate is optimal for each speed. (We had originally set the feed rate when on low and it ended up being too fast for the medium speed setting. Now we have it set well for the medium speed, but it tends to be a bit slow (bit still useable) on low).
That may sound like a lot of complains, but we still are very happy with the stove and think it offered a better value than the other stoves we looked at.
One optional item I’d like to see avaliable for the stove is a hopper extender to increase the capacity of the hopper. I think it would be a simple matter to have an extender consisting of a cast iron top (identical to the one already on the unit), sides to match and sit inside the ridge on the existing top and a sloped bottom to feed the fuel into the existing opening. The cast iron lid could be removed and simply used on the extender.

    Heat Wave

    It’s been in the high 50’s and low 60’s for more than a week now, with lows that often didn’t get below 50. It’s the kind of warm spell you would kill for in mid March that brings the Silver Maple’s into bloom and gives the bees a huge jump start in spring. The kind of day you just want to sit under the maple trees and listen to them literally hum with excitement of the bees. But these above normal temperatures in December bring more concern than anything else. It means the bees are much more active then they normally would be this time of year and that means they are using more of their winter stores, something that is not in good shape after the poor flow this summer and fall. It also means robbing.

    I noticed one hive this past Tuesday at home that had considerably more activity than the others and sure enough, the activity was robbing. A quick peek under the cover told me it was too late for this hive. Chances are that since this hive was too weak to defend it self, it would not have survived the winter anyways. Still It’s depressing to see.

    As of last night though the warm spell was over. It ended with lots of rain and now is in the 40’s and is very windy. We still have been fortunate not to get the snow and freezing rain other parts of the country have had.

    Another Honey Stick Machine

    I recently was informed of another Honey Stick Machine it is on the market. It is not automatic, but sounds like it may work a bit faster than how I’ve currently been filling straws. It consists of a special pump that is made special in india that fills the straws with raw, unheated honey and special trasy that hold 14 straws for sealing. The gentleman selling them says that with two people he can fill and seal 1000 straws per hour.

    The machine costs $1000 and is available from Dunbar Honey Farm, Jerry Dunbar, 586-770-9953. I do not know if that price includes the sealer or not (I’m assuming he uses an impulse sealer as I do). If anyone gets to see this machine or has one, please let me know what you think of it.

    Update: The gentleman who is offering this machin says he knows the the person who purchased the Patent for the Sticky Machine and that that it isn’t being produced yet because he has been unable to get the design to work. This seems to confirm the rumors I’ve heard elsewhere. Dissapointing as I would have loved to save all the time and money of designing my own. I had some hope that the Sticky Machine would soon be on the market again as I have know some people who have seen the Sticky Machine’s Inventer with a working version of the machine, but it appears it won’t be any time soon.

    Honey Stick Machine – Part 3

    IR Detector TransistorI’ve already covered the outputs required from the Phidgets Controller in previous articles. But you can’t forget the inputs. While the Honey Stick machine could be setup to simply run on timings when to do what, and assume that each task is done correctly, it would be prone to problems if anything varried. Even differences in the thickness or temperature of the honey would cause problems. Thus I intend to include quite a few input sensors to make the machine smart enough to adapt to most situations. These inputs will include:

    1. Temperature of the straw sealing heating elements. Temperature when melting the plastic ends is critical to getting a good seal. Too low a temperature won’t seal the straw, and too high will melt though and leave a hole. While this could be controlled by a simple thermostat, it’s easier to adjust on the fly if the computer knows what the temperature is. Plus, sine the Phidget’s USB interface has plenty of inputs, it costs a fraction of the amount that a dedicated controller would cost.
    2. Temperature of the honey. My honey stick machine will include a heater for the honey (or other syrup) to keep it flowing well. We don’t want to overheat or even pasterize the honey (my customers perfer raw honey), but it flows much better at 90 degrees than at room temperature (which may only be in the 60s at my house in the winter). It may also give the computer an idea of how fast the honey should be flowing so as to adjust timing of filling cycle.
    3. IR Emitter and Detector pairs. These will basically function like the safey eye on your garage door. When the beam is broken, something is in the way. In this case it will either be a straw or honey. We will have 4 such pairs to determin if there are straw in the bin, in the filler holder, if there is honey in the feed line (or if we have run out of honey), and if the honey has filled the straw. I expect the positioning of this last sensor to be critical to get repeatability without having to clean the heating elements constantly. Too much honey in the straw and the honey will leak out everywhere, too little and it will leave air bubles and burn though the straw. (Less time/heat is required to seal an empty straw vs. a straw with honey at the sealing location)
    4. Current Sensor to determine if the pump is running. This wouldn’t seem necessary as the computer is telling the pump when to turn on, but the pump we have chosen has overrides that may cause it to turn off without the computers knowlege. Thus I think it would be usefull to have this additional input. It may prove to be unnecessary in actual use (the pump may never turn off on it’s own), but I will include this circuit in the prototype.

    That pretty much fills up all 8 of the Phidgets analog inputs, and fortunately I can’t think of anything else I need to monitor at this point. I will take advantage of several of the Phidget’s digital inputs as well to add features like a ‘kill switch’, power switch, start button, etc. so that it could basically be run without looking at the computer screen (once all the bugs get worked out). The Phidget’s also has 8 of these digital on/off inputs, more than I can think of a use for right now.

    Status Update: I have ordered and received most of the electronics parts that I think I’ll need. I’ll begin wireing and testing circuits possibly later this week if time allows. I do plan on building them in modules and not just one big circuit so that it will be relatively easy to adjust for the final machine.

    Honey Stick Machine, Part 2b

    One other problem using the Phidgets USB interface is that it simply doesn’t not have enough outputs to control all the devices I want to control. We could simply use a second USB interface, but in the interest of minimizing cost I’m trying a different method. Instead I will use the following circuit to control 8 devices using only 4 outputs of the USB interface. It is a relatively simple circuit that can be built with 6 off the shelf 7400 series TTL ICs. It also could easily be expanded so that 5 USB interface outputs control 16 separate devices. (and theoretically up to 128 devices using all 8 outputs of the USB interface) The D-type flip flops are positive edge devices.

    4 Input to 8 Output driver

    One Input to this circuit determines what state the selected output should be in, and the 3 selector inputs determine which of the outputs should be set. In operation the state should be selected first, then the selector inputs should be sent. One significant outstanding issue is if the outputs from the USB interface change simultaneously or not. If they do not then the circuit may inadvertantly change the state of other outputs on the way to changing the desired out. If this turns out to be the case then an input latch and delay will be required to ensure the inputs arrive at the same time. I won’t be able to determine which case is true until I can breadboard and test the circuit.
    Another inherent limitation of this circuit is that the 8 outputs can only be changed one at a time and could effect timeing. In most cases this isn’t a problem, but for the solenoids and other devices that need to be more responsive I’ll use one of the remaining 4 outputs of the USB interface.

    I should note, that after working out the above, I ran into the specs for the 74LS259 8-bit addressable latch and it appears that it could replace the entire circuit above. It may however suffer from the same problem as the above cicuit and may require the inputs be latched and timed so the output is as expected.

    Honey Stick Machine, The Manual Version

    Making honey sticks (or maple syrup) sticks is a straitforward and simple process. The basic steps involve filling a straw with honey and then sealing both ends. The difficulty arises in actually getting the honey into the straw and doing it efficently (so that the time it takes to make them isn’t more than the value of the honey stick itself).Plastic Syringe

    Initally to see if they could be simply made, a sort of proof of concept, and so that we could make some as samples we used a large plastic syringe (pictured to the right) from US Plastics. The tip did need modified slightly to fit inside a standard drinking straw (available from any resturaunt supply store). The tip can be molded by heating it and molding it carefully with your fingers, being careful not to burn yourself. It does work reasonably well if the honey is warm, though is not really suitable for making large numbers because it needs to be refilled every dozen honey sticks, is relatively slow and can be quite a strain on the hand.
    Impulse Sealer

    Sealing the ends or the straw is a simple task using an impulse sealer (left). Again these are available from US Plastics, on ebay and from many other retailers. The heat is easy to adjust with the knob on the front of the sealer. You will need to adjust it by trial and error until you get a good seal. Do not adjust it by using an empty straw. You will quickly find that it needs far less heat to seal an empty straw than a honey filled straw. (I should also note here that the impulse sealer is also very usefull for sealing plastic bags and even making pollen patties, so it is usefull for more than just making honey sticks.)
    Stainless Steel Tank

    Making honey sticks in larger numbers requires a better setup for filling the honey sticks however. Instead of using a heated honey tank, hand pump and manifold that holds several straws, we have used a simple stainless steel pressure tank. This tank (right) is a surplus tank originally used for holding premixed soda (or pop). Mine was purchased on ebay. Honey is placed in the tank and an air compressor is attached to pressurize the tank to 90psi. The straws are then filled using a simple valve with a brass nozzle. It does work better if the honey is warm, though I do not like heating up the honey as much as other systems do and have found this system works resonably well at 90 degrees. Before we start the tank is placed in our honey warmer, but during use it’s placed in a 5 gallon bucket with a band heater to keep it warm (sold for heating up honey buckets by Mann Lake and others).

    To make it easier to fill many straws at once, a plastic or wooden bar with holes (and split down the middle) is used to hold a dozen straws at once. This makes it relatively easy to fill and seal several at a time (below). It does make a bit of a mess, hence the newspaper for easy cleanup, but does not make as near the mess as the plastic syringe. Once sealed the straws ends can be cut close to the seal and washed in warm water to make the finished product. With practice you can get to the point where many of the straws are sealed very close to the end and don’t need cut.

    Filling Honey Straws Sealing Honey Straws

    I am building an automated honey stick machine as it’s simply getting to take too much time when making honey sticks by the 1000. But if you are looking to make some as samples, or even several hundred at a time, the above works pretty well with considerably less expense than a commercially available system.
