dial back timing light, what makes it tick...?

LM358 op-amp and an NE555S were the heart of the dial back TA-2200 dial back mainboard. Along with a few diodes, resistors and transistors, a MOSFET and a huge 680V capacitor to fire the xenon strobe. Not too complicated but nothing Im going to re-engineer for a dial back box. I think the 555 will be the start for a new build. I bet an arduino could do this with a few lines of code. Ill keep this thread informed. Seems someone else besides HF sells this light TL2200 TA2200 Timing Light Tester for 12V Gasoline Engines - Easy Engine Timing Adjustment Tool
