I took @AnalogKid , post #12 suggestions and put it on a bread board powered by 3 V Li cell but with only a bright red LED. SW-1 SPST NO, power , SW-2 SP2T, alternate LEDs, & SW3 SPST NO, both LEDs on. Will draw it up later if wanted.
And if you’re unfamiliar with micros to start with, there is a programmer into which you plug the ATTiny, and which plugs into an USB port on your laptop. Then, you use the Arduino IDE (which you likely used to write the code) to upload the code. Swap the ATTiny from the programmer to a socket on your circuit and Voila, it runs...Is there not a way to send a PM on these forums?
I'm certainly interested, Bernard, though I may already have some of the components. I've got lots of different SPST momentary switches, not sure about latching, though. And not sure about double-throw, I'll have to check.
I'd definitely like to discuss it more, but can't figure out where the PM button is!
And Wolf, I like your schematic, as well. I'm just not sure I understand the ATiny IC thing. Would I need to get equipment to program it myself?
And I haven't forgotten about you, SamR! I like your schematic, as well! I'm trying to figure out what would be easiest for me to do!
Click on the person's name or avatar and select start a conversation and you are in PM. Some folks have that option turned off if they don't want PM's.Is there not a way to send a PM on these forums?
And using the Arduino IDE, there’s a library available to turn a pin into a capacitive switch. Saving you the space for an external switch. You just need a wire to/on the case.That’s why I like uC design... this is all you need. Actually take one led out on below.. it’s all in coding.
could be run at 3.3v, Vf of red and gr led should be about 1-6-2.1v
power up start blinking whatever you want.. then switch colors
do this as many times as you like
power down into low power mode and go to sleep or add a latching circuit and actually cut power

Hi akIn #50, the DPDT lamp test switch can be replaced with a much smaller SPST switch and two 1N914 diodes.

hiGood question, all I had is what you see. My interpretation is that since it says both source and sink it is for Pin 3, the Output and Pin 2, the Trigger. I have a few different part numbered CMOS versions but never used them. When I was playing around with timers I used the NE555. I ran across that last nite while perusing some online PDFs and found one on timers. http://www.talkingelectronics.com/te_interactive_index.html Look for "50 555 Circuits A Free EBook" Lots of good tidbits on Hans' Timer.
hi BernardSome of the problems noted in post #50 were avoided in post # 42 by squelching action of
oscillator by R3 & D4, & FDD6530A with lower gate V appears to be a better SW than 2N7002.
