    Boosting the Amper and altering the frequency

    Right. What was I thinking :oops: Let's say I will use 5x output pins of Arduino. Do I need 5x voltage regulator (XL6009) or can I divide +out of one regulator into 5 for each pin just like image below? (from post#86)

    Boosting the Amper and altering the frequency

    @Harald Kapp Hello. It is already connected minus voltage on the battery. Do I still need the connection which is highlighted with red colour? (Schematic on post #86)

    Boosting the Amper and altering the frequency

    From 5V: 5V/138Ω = 36.23 mA From pin_8 =5V/470Ω = 10.64 mA (not continuous) If I draw the current from the battery, instead of 5V pin of Arduino (I remember you said I can by increasing 138Ω resistor's value by a factor of 2.4), does that mean I can connect 10x safely? Total current draw from...

    Boosting the Amper and altering the frequency

    @Harald Kapp I have enough transistors and voltage regulators to try with 10 output pins at the same time but I don't want to harm the Arduino. Is this safe?

    Boosting the Amper and altering the frequency

    Thanks for the calculations. I learn alot from your posts. I bought a 27Ω resistor but couldn't test the device with it yet because of colony issues. I will test and post the results this week. I have one question for the device count. We have built this device for only 1 hive whereas I have 10...

    Boosting the Amper and altering the frequency

    Thank you so much for the clarification. I was making a huge mistake by summing R_eq of the grid and 100Ω. For the worst case (35W power dissipation), I'd better mount a heatsink (this) on BD135, right? Heatsink's thermal resistance = 30 K/W

    Boosting the Amper and altering the frequency

    In datasheet of BD135 it says that max collector current is 1.5A What should I do to achieve at least 1-1.2A current? I assume I need a heatsink at that level of current. I built a new grid system. now each wire (10x) has 180Ω resistance and all connected parallel as below schematic: @Harald...

    Boosting the Amper and altering the frequency

    Hello. Judging from the schematic in the post #82, I think It looks like 5V but I'm not sure. It looks like 5V signals comes from pin_8 of Arduino through BC107 to BD135. But I'm no expert :) Should I also add the grid's resistance? 100Ω resistor will be connected in series to a grid system...

    Boosting the Amper and altering the frequency

    Thanks. I think this is the issue. 10.000 of them walk on each frame. And some wires got loose. I will make them tighter. I don't know if it is necessary but I am also planning to get a heatsink for the transistor. Would doing this also reduce the current on the grids? and is 100Ω ~20W overkill?

    Boosting the Amper and altering the frequency

    This time bd135 is dead again (I think it started to melt). I adjusted the voltage regulator to 29V. It run 75min without any issue. I re-run the system on another unit. This time gray smoke came out from BD135 after 5min. I don't understand what would be the problem. (I measure 5.5V on...

    Boosting the Amper and altering the frequency

    I revived the Arduino by using another arduino to upload the bootloader. :) First day I tried 29V and it didn't work for me. When I get home I measured the voltage accross the grid. It was jumping 0-29-0-29... as I wanted. Then I decreased the voltage by turning the pin on voltage regulator...

    Boosting the Amper and altering the frequency

    Thanks I asked because I thought there might be different pin current. My BD135 is also dead. (It died before Arduino.) I measured arduino's pin_8's voltage as 6V whereas it should be 5V. This might be the cause of BD135's failure or just a faulty unit?

    Boosting the Amper and altering the frequency

    @Harald Kapp My Arduino UNO is dead, unfortunately. Can I use this same setup on Arduino Mega?

    Boosting the Amper and altering the frequency

    I couldn't make them sting. I tried different voltages hence different currents, It does not work. I will do more research.

    Boosting the Amper and altering the frequency

    Hello. I have tested it on the hive. I think I need less current. ( I probably need those thick copper resistors.) I want to see the current on each frame before getting a resistor conencted. Can I connect one of these (English schematic is at the middle of the page) on each frame? Also I want...

    Boosting the Amper and altering the frequency

    From every single one of them except the queen. :D They will try to sting the glass because of the electrical shock and drop the venom on it. @Harald Kapp I have stabled the system in a plastic box and measured the voltage and amps only on 1 resistance wire (0.08A - 28.5V) as in schematic...

    Boosting the Amper and altering the frequency

    Can you estimate how low would it be? They basicly will swarm all over the frame once a single drop of venom is dropped. I will try the setup on Tuesday or Wednesday (depending on the weather) and will post the results. What should be the 138Ω resistance's W value? I have 138Ω ~ 2W. (5V/138Ω =...

    Boosting the Amper and altering the frequency

    @Harald Kapp I think I figured out the problem with the frames. Please let me know If the logic is possible. I will explain it in 2 schematics. In the first one there will be no current flow as you pointed out. BUT If there are bees on it and they touch the red and black wires at the same...

    Boosting the Amper and altering the frequency

    Thanks. Yesterday I have studied series-parallel and shortcut circuits. I have learnt a method by using letters. And I draw this below schematic on a web-based simulation software, but It says 18 bad connections. Does It look OK? Also, this is the final schematic of the circuit now: Thank...

    Boosting the Amper and altering the frequency

    I guessed :))) drawing was short-circut but since I measured the R_eq almost close, I thought I couldn't draw it right. I learnt the concept wrong. I thought + and - shouldn't touch each other on the grid. I can't visualize how to connect them properly. I will work on the frames. I thought I...
