MIDIbox SID-LC Update
MIDIbox SID-LC v1.0-PROTO PCB Layout Draft 1
(Click for 300dpi version…)
Wow, I didn’t think I would get this finished tonight, but… Well… I have. This is the first draft of the PCB layout for the MIDIbox SID-LC v1.0-PROTO. That is, the first draft of the design for the prototype for the MIDIbox SID kit I’m hoping to produce and sell.
While it is true that I’ve already built a working SID-based synthesizer (photo gallery retired), I want something a bit more. So, I’ve come up with this… It’s a bunch of the MIDIbox modules all squished on to one board. Basically, this is everything one needs to build a MIDIbox SID Step A (Basic Control Surface) on one easy to assemble board.
I’m feeling pretty tired now, so I think I’ll head to bed. Well, as soon as I make a backup of all that work.
Suffice to say, I’m pretty happy that things have come this far… Now I just need to order a complete set of parts for it, confirm that they all fit the on-paper layout, then order a set of prototype boards.
If that all goes well, then I’ll start seriously looking into what it will take to assemble 50 or 100 kits and sell them.
Now all you need is a box ..
Now all you need is a little box.
We were talking about the PSU part, are you still re-doing it ?
Pity it all fits “so well” in that board that there’s no room for some heatsink for the two regulators.
You could still put it in the box (if you are going to use one too) and eventually use some short wires to connect the 78XX to the board, it should go fine the same.
Or let people that buys the kit do it ;)
Re: Now all you need is a box ..
The PSU is done. If you look above, see how the regulators hang off the edge of the board? My plan is to have slip-on heatsinks on them, hanging off into the air to give them plenty of space to radiate heat. The heatsinks I am planning on using are Aavid Thermalloy 579302B00000G, and their outline is indicated above by the dimly shaded red area around the regulators. Hopefully that’ll work well enough. :)
The enclosure itself will be a Hammond 1455T1601 (WARNING: PDF) into which the board should slip nicely into the grooved edges of the case, providing all the support it needs. Hopefully this will work out well. :D

Good work for one night, man! :)
Re: Now all you need is a box ..
Thank you. And all for the cost of a bit of sleep and not getting laundry / dishes done.
Please remind me to scan in my prototype logo drawings for you. :)
