Step 10Finish up the control circuit
glue the switch to the top of the 555 chip to keep it in place.
solder the power input wires to the switch as shown, or only one of them if you are not doing the multi-battery-type option. with the multi-battery option we will just toggle the switch one way to turn it on with rechargeables and the other way to turn it on with alkalines. very much a hack.
add wires for the common ground and the led positive output (1 wire for blinking output and 1 wire for non-blinking output). if you are using the R3 and R4 dimming resistors, the led positive outputs are at the other leg of those resistors.
i initially built with only blinking led's so i 've only got the 2 wires shown.
