    Boosting the Amper and altering the frequency

    Ohh. I thought I should have to add a diode like in the link. Alright then, It looks fine.

    Boosting the Amper and altering the frequency

    @Harald Kapp I find the problem, transistors are fried due to reverse connection of +in and-in. (mistake :)) In your post you said i need a driver. Does my current setup (only difference is 138 ohm res value is increased and is conencted to 12V, and same setup for 5 pins) is OK? I don't want...

    Boosting the Amper and altering the frequency

    @Harald Kapp I built one more, on this one when Arduino's pins set to low, 4 of them show 6.8V, one shows 12.2V. Please check my above schematic and tell me what I am doing wrong. I couldn't figure it out.

    Boosting the Amper and altering the frequency

    I tried to draw the schematic with breadboard. Same transistor-resistor-voltage_regulator setup is also applied to pin,3,4,5 and 6. So that means 5 outputs total. I didn't add them on the image below because it becomes too complicated to draw. Now I measured again the voltage at the end of the...

    Boosting the Amper and altering the frequency

    OK. Same schematic in this post but without any diodes. I will draw the updated schematic and share. But there is a strange occurance. In morning, I measured it 0V when off. And now in evening, I measured again. I measure some outputs as 0.1-0.3V when off. And I am almost sure tomorrow morning I...

    Boosting the Amper and altering the frequency

    Hello:)I am doing beekeeping as a hobby (currently 5 hive) and I am making ointment with venom for personal use. Thanks. Current is fine. Only problem(?) is non zero voltage when off. I thought it was a problem because 4 outputs show 0V when off and only one of them shows 0.8V now. Can it be a...

    Boosting the Amper and altering the frequency

    @Harald Kapp hey. I finally built 5 outputs from one Arduino. but some outputs show 0.2-0.8V when the pin is off. It should show 0V. I tried with different components too. All of the components are OK. What might be the issue?

    Boosting the Amper and altering the frequency

    @Martaine2005 @Harald Kapp Hello again. I have used my first circuit as a test bench. Turns out all of the voltage regulators are working just fine. But on three of my new setups multimeter now shows 20V constant. Doesn't shut down the current at all. For testing I powered the Arduino from USB...

    Boosting the Amper and altering the frequency

    I think problem is the voltage regulators. It seems like the batch I bought is problematic. I tried them on a working circuit and result is the same. I was so shocked because I have checked more than 20 times each path on the circuit and compared them with both together and to the diagram. Also...

    Boosting the Amper and altering the frequency

    Hello. I have tried to build a new one in a new box. I have tried with 3 different voltage regulators and 3 different other components but result is always the same. Normally, multimeter should show 3 sec 20V and 3 sec 0V. Instead It shows 3sec 20V and 3sec 17V. What could be the issue here...

    Boosting the Amper and altering the frequency

    Thank you. As I understand I will make a terminal on +out end of the boost up module to connect multimeter in series. I will measure amps in October 1st and post it (I am using formic acid solution for better survivability hence the long wait). I assume It won't be constant value. One strange...

    Boosting the Amper and altering the frequency

    But the current draw is not too much. When I go home and put the 12V-4.5Ah battery to charge, It becomes fully charged after 15-20min. (In my charger's manual it says that it would be charged from 0 to 100% in 6.5hr) I don't know how to measure the current draw on the open loop when the bees...

    Boosting the Amper and altering the frequency

    @Harald Kapp Hello. I have been testing the system for a while now. I have a question regarding the distribution of the current. When I use a single system, device collects 50mg. But when I build it like in post #116 efficiency drops to 15mg per device. It sometimes collects 50mg for one but...

    Boosting the Amper and altering the frequency

    @Harald Kapp Hello. I will start to assemble the setup and wanted to ask and make sure about the (+)out of the voltage regulator before starting. As long as the regulator can keep up with the current, can I seperate it into 5 pieces, without adding any other circuit components to the seperated...

    Boosting the Amper and altering the frequency

    Thank you very much for the explanation. To prevent damage to system or prevent possible fire(?) should I put 1-1.2A fuse at the collector of each BD135? (Assuming voltage regulator allows that much current flow.) Or simply where should I put a fuse? There is also R_limit at collector end. But...

    Boosting the Amper and altering the frequency

    Alright. Thank you very much. I was watching my electronic circuit tutorials and the teacher was talking about diodes. I don't know why but I imagined current might flow there if I don't put those.

    Yes. I fixed them :)

    Boosting the Amper and altering the frequency

    I drew the diodes on paint.:) Black ones aren't diodes? I edited the post and renewed the screenshot. I added diodes on the software. I read that diodes do not allow the current to pass to a certain direction according to how they are installed on the circuit. I thought current might go to the...

    Boosting the Amper and altering the frequency

    @Harald Kapp Hello. I was reading about diodes and I wonder If I need them on the build with multiple outputs as below. Or is it not necessery in my case?: I couldn't make it work with only one but this does not mean device is not working. I better test it with at least on 5 unit at the same...

    Boosting the Amper and altering the frequency

    Thanks. I was thinking to reduce the max current. I will keep it below maximum output current of the regulator (4A) It is good to know that with one I can do that. This will save good amount of space and wiring.
