[NSRCA-discussion] Heathkits

I occasionally have used my old timing light just to see that I am getting a spark with a small engine.

Hang onto the timing light! Some day you will want to work on a small engine for a mower, generator or similar. It takes an old fashioned timing light...

I'm still using a Heath ESV, one of the few that does single nicads.
Though, I have not found much use for the timing light for a while -  <VBG>

Agree on missing the stores and the kits.  That was my introduction to Elec. Engineering and programming which has ended up putting a lot of food on my table over the past 20 years.

I used to live at the Heathkit store in Pittsburgh when I was a kid. Never 
used their RC stuff but I did build one of their robots. I miss their kits.
