    I'll take two!

    I think, as long as the other guy still wants me to put one together for him. Those dc/dc converters look pretty cool! that way i dont have lead the power back from my scanners to power the op-amps. sweet!

    Uh oh, im starting to spend money again :/

    Here is a photo of the front side of the board. You can see, it will be a breeze to assemble, no SMT parts. For just the board, it's $17, the whole kit including header connectors is $40. The pots and dc/dc converter make up a bulk of the component cost!

    I dunno' I hope by early next week. Pretty cool that drlava and I live < 50 miles apart!

    BTW If you don't want to, you don't need to populate this whole board. You could easily make a four channel, or even an XY driver with no blanking at all.

    But wouldn't it be a hassle to only sell the parts for a certain number of channels as opposed to a full kit?

    Huh? No. I mean if you buy the board only!

    The only weird part is the DC/DC and it turns out it's not so weird. But unless you buy a bunch of them, they are somewhat expensive.

    TLO72, TLO82, LF353 will all drop into the IC sockets. I'm sure there are even more op-amps with the same pin-out.
