I just built one of these - the 12v version for Eurorack - using a PCB, panel, pots and knobs ordered from Thonk, and the remaining parts from Mouser. A very straightforward and easy build, and it seems to be working great. Sounds awesome, and only 4hp.
The most laborious part was identifying all the parts on Mouser. Things like the 10 pin header, I literally spent about 30 mins sifting through a million different items before locating the correct one.
So to save some work, the following link should take you to my Mouser project page with all the required components and quantities:
https://www.mouser.co.uk/ProjectManager ... 9758aa1fa0
These parts all seem to work and are the correct dimensions for the PCB.
In case the link dies or doesn't work, I also have an excel spreadsheet that I am attaching. This was downloaded from Mouser with all the part numbers, so should be easy to import into your own Mouser account. Under the BOM tab in Mouser there is an option to import a spreadsheet.
A few notes, with apologies if any of this is stating the obvious:
- My Mouser project doesn't include the pots or knobs as I got these from Thonk. So you may need to add these in. Be sure to get the right pots, as they solder to the PCB, so need to have the correct spacing of the legs.
- I ordered 4 of each of the NPN and PNP transistors and then used the HFE feature on my multimeter to choose the closest matched two of each. If you're not fussed about matched pairs, you'll only need 2 of each.
- I chose audio grade electrolytic capacitors. Who knows if this makes any difference, but I thought I might as well spend a few more pence. If you're desperate to save a tiny amount of money, cheaper options are available.
- The BOM lists various possible values for the electrolytics. I used 10uf for all three.
- For soldering the sockets, you have to make sure you are using the correct lugs. I looked at the photos of what others have done.
- Cost: while the parts came to only about £13 or so, shipping from Mouser was nearly as much again, and then with VAT the Mouser order was £31. The PCB and parts from Thonk were about £30. So all in this cost about £60. I've seen this module sold second hand for less than that. I am just getting into DIY modules and really enjoying it, so it made sense for me. I believe Mouser orders over £33 qualify for free shipping, so it would make sense to lump multiple builds together. I looked at Rapid, Farnell etc but Mouser was by far the best in terms of having everything required and being able to order small quantities.
- Finally, I was a bit shocked by how much plastic packaging came with the Mouser order. Several things were double or even triple bagged. It seemed excessive, and that plus the shipping made me think about the environmental impacts. I'm old enough to remember the days when you would just go down to your local electronics shop and they would put everything you wanted in a paper bag. That's long gone - now it's all coming from one insanely massive warehouse in Texas.
Anyway - big thanks to negativspace for putting this project out there, and to Thonk for the PCB and panel kit.
