Has anyone on here played with pummer circuits? If so, do you have any circuits you like?
(Please don't just send me links to pummer stuff online that you've never tried. I know how to use search engines)

The modern online retail economy sucks!
I need one 74AC240 chip for this. I could order a pack of 10 of them from Amazon (yuck) for $12.25 + $6.99 shipping, a single one from ebay for $2.50 + $12.50 shipping, a pack of 10 of them from ebay for $4.99 + $5.20 shipping, or one for $2 + $10 shipping from Mouser.
UGH
I would pay $5 for one if i could get it in a store right now in person, using my own body to pick it up and pay for it
I got my chips from @ai6yr today and built a pummer. Unfortunately this pummer is a failure. I'm not sure why yet
@ai6yr I built it on perfboard because I wanted this to be non-permanent in case I messed something up. I might go ahead and try building it dead bug style to see if I can get it working that way
@ai6yr it's not completely kaput. It does turn on when the lights go out. It just stays on instead of slowly pulsing. If i knew more about electronics, this would be an important clue
