DIY bugCrusher

the other day i posted this:
…this could just go on and on, and on….
so here’s a link of something i should just build:
i need one of these:
so will try n get a smaple for free…
there’s some help here:
as there’s another chip worth grabbing from (as well as the AD781, the AD633 looks good for building ring modulators)

well, i have since blagged a couple of the AD781 Sample and Hold amplifier ics from (handy working at a university) and just need the other chip (40106 Hex Schmitt Trigger) now. whilst i was on the blag at, i asked for the AD633 chip too so i can build some kind of ring mod – this is mentioned by tom bug way down the first link).

i need to think about tubs or boxes to put things in too…

anyway, here’s the board layout:

i guess i could add the parts to a build doo-daa at

update: i think i have all the bits to make this now (jan 29th 2011!), so will be getting started asap.
one thing i haven’t fully understood is how the board works… i thought at first it was strip board, but it’s a different type of protoboard, one with no connected holes. i need to make the connections with wire & solder… that’s new.
here’s some links:;topic=71523.0
