Hi Thomas, Great Project ! I appreciate your work on this. I just made two of your boards and tested them with the code your provided on git hub - worked great. Could you share example code for data logging - storing the data to an SD card with a time stamp? Or do you of know of someone who has posted this kind of example ?BTW, I fabricated the boards using the Controleo2 reflow oven setuphttp://www.whizoo.com/I reflowed the sensor side first. After it cooled, I applied paste solder to the other side and then reflowed the shift register and resistor side. Thanks

Wow! Great, Thomas. Now I can start testing the shift registers using your code.Thank you!!
I just posted some code here: https://github.com/hydronics2/Bee-counter-3.1/tree/master

Ok Thomas, thank you for your reply. I will wait for it.Regards,Juan
Any chance you would be interested in collaborating on an updated design using the gap sensors and Nordic nrF52 BLE as a data processor and transmitter? I've picked out some nifty shift registers too. Everything low power to run off small LIPO cells.napaogdenatgmaildotcom
yes, I think a gap sensor would work great. I went with the reflective sensors because I thought at the time they were less expensive and then became interested in mfg with surface mount parts.
I added a zip file with eagle docs next to the schematics.
sorry I don't really have a good sketch to publish right now. I'll try to get it on github soon.
Thomas,Any chance you'll share your Eagle files? I'd like to order a solder mask from OSH and would like to play around with adding an inexpensive wifi module.

Well, I guess were going to develop independently at I have not received a response. napaogden_at_gmail.comIs this thread dead?

You did a great job of giving lots of links to relevant and helpful places. Thanks! A great instructable
Hi Thomas,I was able to self-build your bee counter using white plastic materials for the gates and beam IR sensors. Into the lab all the gates worked fine but, outdoor, the sunlight cause problems, as you commented before. Now I want to forget this design in order to build a new one, following this instructable. But I can't find the Arduino sketch anywhere! Can you help me on this, please?Thanks in advance,Juan

Thomas,I really appreciate your project. I'm working on a similar open source bee counter using two stacked HY810H 3/8" gap sensors instead of reflection sensing. The sensors form the gates and the current is very low at 1.5mA each @ 3V. I have a working prototype ref. http://hivetool.org/w/index.php?title=User:Adrian I'm wondering if you would be willing to consider the gap sensor? I'd really like to try your board design with the shift registers and modify it to use with the HY810H sensors. There are a few reasons for the change, less power, higher signal confidence using a narrow beam direct path, unaffected by target color. At least in theory. Please reach me at napaogdenatgmail.

Thank you for your answer. I have already ordered all components for 3 counters so we'll see it in action. :)
the gates are 3/8 wide (9.5mm) and the headers are 8.5mm high. I've not completed the testing and finish the programming to distinguish between drones and workers but I think it should be pretty easy to do.
Appreciate your effort! Great project! What is exact gate size? Side - wall to wall diameter and trough the gate diameter?Is it possible to distinguish drones from workers with current gate design?Thank you.
Congratulations on a very useful project! I'd love to give it a go.What is your experience with it's accuracy when lots of bees are leaving (or entering) at the same time? Do two or more bees get counted as one? The gates obviously need to be large enough to allow drones (& queen) to go through but I wonder how much space that allows worker bees to crowd the gates?I have zero experience with Arduino, but I was wondering if your code can be directly used on a Pic MCU? I normally use Picaxe MCU's (easy to program) but translating your code will be a challenge.... Do you have a program flow diagram?Thanks again!
I think what you did is called a "balun" - it gets ground-biased 0-5 volts on input (when pins are switching between equal voltage and 5 volts difference) and produces differential 5 volts peak to peak AC voltage on output (when pins always differ by 5 volts, but are constantly swapping polarity). But your device is also a transformer, so the output voltage is higher (or lower), depending on the turns ratio.I'm trying to drive a buzzer myself right now with a similar generator (0-5 volts), but don't have any auto transformer at hand, so I would try to use a capacitor to remove DC offset and hope it works.
Hello,this looks like a great Project :)just one question.. what is the piece of wire that goes from the IR light to the circles on the end in this picture?I am a complete novice to this stuff so i do apologise if it is a stupid Question.Many Thanks, Mike

Just curious what the optional 0.1uF capacitors do? I'm in the process of building my third bee counter...first two appear to be working great!
Great project! I started a few hives last year in partners with a long time bee keeper. I just got your boards from Oshpark and am building the sensors now. I also found a good, 200 Lb outdoor rated scale on Amazon and will hack that to give me weight change information. Thanks for making this and making it open!!

Hi,first of all, great project and thanks for sharing! What do you use as absorber on the button of your Bee Counter. It looks like some black PVC shield? Is this absorbing the IR light enough?Have you tried to do it the other way arround? Use some reflective material at the button (getting a HIGH if no bee is under the sensor) and the bee will pull the sensors to LOW? thanks!martin
hello, I am imam from Indonesia. I am very glad to read your reserach. I have plan to build people conter at the train, the sensor can count people entry and out likes your project. is possible if your research Wil be implemented to our project? thanks

Could you stick a different reflective disc on the back of the queen and use an adapted version of this to monitor when a swarm leaves or a mating flight occured ? This is very cool. Going to get some grad students to try it !
