Hi Cole.
makes and sells PCBs of his own designs. EFM has its own forum for those
designs, and several CGS forum people are also in the EFM forum.
connect the ±15v and GND terminals in the header to different coloured wires
( stranded, not solid core, about 1 mm diameter) and then solder the other
ends directly on to the CGS PCBs. On CGS boards, it's definitely strong
enough, and you can still easily remove the boards or completed modules from
the MOTM-900 distribution board, when servicing or tweaking. I use small
bits of heat shrink at 4" intervals to keep the wires together.
If you're starting out ordering components, it's worth thinking about what
modules you are planning on building, working out a big parts list, and then
ordering larger amounts to get bulk discounts. (saves on shipping/delivery
too) Some components are used a lot - 100k resistors are very common, as are
10K and 1K. In bulk, 1% resistors can often be nearly as cheap as 5%
resistors, so it's worth going for 1% if bulk buying. Other common items are
47K linear pots, 8, 14 and 16 pin IC sockets, 1N4148 diodes, 47K, 22K , 2K
resistors and some other values, and TL072/TL074 op-amps. BC547 transistors
are used a lot in CGS designs, and 0.1uF and 100uF caps are common.
Ebay occasionally has some bargains, though watch out for hidden high
postage costs!
IMO, it's well worth spending time looking through different electronics
catalogues and comparing prices of components. It's a bit boring, but pays
off in the long run. As an example, in the UK, RS components are usually
expensive, but when buying tubes of 25 ICs, they often work out way cheaper
than alternative sources. In one case, it was cheaper to buy 25 op-amps in
a tube than to buy 15 individually.
Cheers,
Dave.
