Ok, found this at Best Buy. I'm thinking it might work for a blinking RF circuit. They are 2 CD box sets with era music from each decade starting with the 50s. I saw someone playing with them and the red blinking LEDs caught my eye. 5 LEDs blinking from left to right. $9.99
You can barely see one of the LEDs lit up at the top of the box
Inside the box is a small aprox 2.5" square by 1" thick plastic enclosure.
I bought 2. Had a hard time figuring out how the darn thing came apart. Then I had an idea.
The backs of them have a battery door cover. They take 2 AAAs.
Here's a pic of it once opened up.
Two screws hold in the circuit board to the case. Remove them and it comes out easy. I just cut the wires to the speaker.
And here's how I'm thinking of wiring it up. I'll disconnect the 5 LEDs from the front of the board. I'll solder in wires from the contacts of those previous LEDs alternating to only 2 LEDs. In theory this would make the 2 LEDs blink with an extra blink on one LED ever 3 blinks. Does this drawing make any sense?
I figure I can remove the push button and replace it with a merc/tilt switch.
Here's a size reference pic.
What do you all think? Like I said I got this at Best Buy. They had a lot of them. I'll post my progress pics if this actually works out ok. If it does I'll be putting it in my hollow DP 95 RF.
