Tell us about yourself!
Thanks. The breadboard was just used to hold up the project for the picture. Well, in parallel resistors drop current before each LED which could cause a dimming across the line (I may have got some bad resistors, or these batteries may be old and not putting out enough power even though they are new). I did set up almost the same circuit on that breadboard (parallel with same exact resistors and LEDs but only like 7 and still had a drop in brightness). I am just going to run my resistors through my multimeter and the LED stats through the calculations. I am just adding this for anyone who may be using this convo to troubleshoot, you no longer need to respond Alex. If I figure out the problem I will get back to you. Thanks
*Never mind the breadboard in the photo.
New batteries checked on my breadboards voltmeter so no the best, but I believe that when LEDs dim in parallel it is cause by a current drop (right?). I considered inconsistency of LED output (due to production standards) but since it's power supply side dependent on which side is lighting brighter (because I did switch it around and the opposite side light brighter), I am considering the resistors may be too high a resistance (I checked the circuit without a switch so there is no resistance there fowling things up). Thanks for he help. I too was a military electrician, wish I knew more about engineering though. Never ins the breadboard in the photo.
Thanks for the plans. I purchased from your supplier from the links but appear to have a power drain on some of the LEDs. It may be from the resistors if they are too strong a resistor but I was wondering if you have come across this problem before? The one side lights up bright the other dim, if I switch power to opposite sides (but correct anode cathode position) the new side is the brighter side, so we can rule out wiring. Thanks again for the Awesome device. My friend printed the case and I did the electronics (I suffer from a condition that puts me in the ER up th 6 times a month so this will help until they finally get around to giving me the port line).
