I got three AAA batteries, soldered them together in battery back fashion, wired the positive lead up to a switch and connected 4 LEDs to it. I have thin wire going from the batteries to the LEDs and I wrapped them all up in electrical tape. I also wrapped the batteries and the switch in electrical tape. So basically the light has 4 wires with lights on the end that can be bent in any manner necessary.
The LEDs have a 3.3 forward voltage and I think it said a 25 mA forward current or something (the current they are receiving in the circuit is 25mA). They are wired in parallel. Regardless, the thing works great for a light to see my keyboard in the dark but the electrical tape has this obnoxious smell to it. I started to notice that electrical tape had this sort of smell after I put it on the edge of my desk to make the corners not as sharp (so it wasn't hooked up to a circuit at all). Is that smell normal?
Are there better solutions than wrapping all my projects up in electrical tape that allow for the same flexibility?
Thanks.
Also, a side question, how long do you think 3 AAAs will run 4 white LEDs w/ a 3.3v voltage drop each and using 25mA? I didn't have a battery holder so when they die I am going to have to redo the circuit (I needed this done before I had time to get a battery holder).
