@davee Thank you for all your feedback! I will play around with decoupling capacitors when I get the time, to see what exciting and erratic effe...
Here is my circuit diagram, with the MOSFET and LED. Took some time, work keeps interfering with my hobbies...
@zander Hi Ron, and thank you for shooting straight - as always. I have been looking at several different sketches/scripts, and trying to...
@davee; Thank you for all the tips. I will go about this the "old school" way. I used Fritzing to draw lines on the PCB actually, I never built th...
Hi all! @zander, @davee After a small break I had the time to sit down with this problem/challenge again. Some time away did the trick. Fast rec...
@davee This setup works, the LEDs light up for 2 seconds, then idle for 38 seconds. 2 5 volt LEDs in series, fed 9 volts. I will take simil...
@davee The gate pin of the mosfet is connected to the out pin of the 555 using a 2.2kO resistor, as Bill showed in his video using the Arduino. The...
@davee Swift and precise as always, thank you for all the information. Bills excellent video has been seen a couple of times, prior to trying this. ...
Video of working setup, approx. 2 seconds light, approx. 38 seconds pause.
@davee @zander So I followed your tip on the mosfet, and I used a IRF520NPbF. To test it I used a 2.2k resistor from the OUT pin of the 555 and co...
@zander ; thank you! Looking into that, it seems they have different forward diode voltage. As I understand it, this means how much the voltage will...
Continuing this project, what would be the best way to handle a higher current? The radio I intend to use draws about 900 milliamperes, a lot more tha...
@davee; you were spot on about the diodes. I removed the ones I had in the previous setup and put in 1N4148 instead. Now it works like a charm :) See ...
@davee Thank you so much for your reply. I have some of these 1N4148, I will try these after work today. I have to go thru my mail when I get back fro...
