MINT Parts List - Suggestions/Advice

[Earwax]

I got some good advice on soldering SMT opamps in this thread

It's really pretty easy once you get the hang of it. Use poster tack or something similar to hold the chip in place until you get the first pin soldered in place. At the end, clean up any solder bridges with solder wick. But work quickly with the wick, it's easy to overheat the chip while doing this.

It looks to me like you could just squeeze a Pimeta and two 9V batteries into your Hammond J12 enclosure. You'd turn around the Pimeta board from usual, the batteries would share airspace with the logo end of the Pimeta board, and you'd run shielded wires from a tiny pot into the space for the ALPS pot. You'd certainly want to be charging the batteries in place, and building the Pimeta to keep current draw down, consistent with keeping cost down.

I'm ok if such an amp can go 10 hours between charges, that gets me coast to coast.

Syz,

No final decision has been made on the Pimeta vs. MINT project. It's on hold till I get another Cmoy built. I think I've come up w/ a project that will challenge my skill and abilities sufficiently before taking the next step.

Basically what I need to do at this point is design a custom board layout in a "L" configuration so that I can shoehorn a Tangent-Moy into the Hammond C801 case that I've got. So I'm currently searching head-fi for the freeware program that I've heard about that lets you do circuit layouts and such. I really think that I need to do something like this to force myself to learn more about the way these circuits actually work rather than just taking someone else's hard work and piecing another amp together. So I ordered up a bunch of parts today from Digi-key and Mouser so that I'll have stuff to play with over the few days that I get off around Christmas and New Years. I've got enough to build 2 Moys (save for the extra opamp) so it shoud be a good time, all for around $40 shipped.

Thanks again for all the advice.

GC-Prevue is the free Gerber viewer that tangent recommends on the windows platform.

It's a blast drawing circuits in a good drawing program such as Adobe Illustrator. Beats any video game I've seen. You can keep the actual etching on a separate layer, and just print that layer when you want to etch. I keep "Snap to Grid" on most of the time, and group odd parts like pads with invisible boxes that match the grid.

Alternatively, throw a RadioShack 276-150 protoboard on an enlarging xerox machine or scanner, and make many faint copies. I'm sure you can implement your circuit in the space you have. Tangent's Micro CMoy fits into your L without making the turn!
