Hi Ted,
The parts list is in the article, along with step-by-step instructions for the build. If you don't have a copy of this issue (MAKE Volume 13), you can buy a back issue or PDF of it in the Maker Shed.

- my post-build tips
You must be logged in to reply.
some quick tips, most likely to benefit utter n00bs like me. (i've built from kits, but that's about it.)
* if you're having trouble finding a board for this project, consider using perfboard instead. i learned a lot more about the circuit's design that way, and didn't have any insurmountable problems, even though it was my first time using it instead of a pcb.
* i added two additional 3-port term blocks: one for the programming port, and one for the 10k pot. this was a big improvement, and an easy mod, since i wasn't using a pcb.
* i suspect others have had trouble finding a 250uf capacitor - i certainly did. i traded a 220uf - much more readily available, at least where i live - without any noticeable difference.
* i also traded out the multi-turn pot for a single-turn pot - it's just a little simpler for volume control.
hope this helps someone - most of all, though, don't be intimidated by not having a board! perfboard is easy enough to use, and gives you a lot of flexibility to make changes if you want to.Posted by fearboy on December 28, 2008 at 12:25:09 Pacific Time
- 250 uF capacitor

does anyone know what voltage or other specs are needed for this 250uF capacitor and where i can aquire a plain circuit board that i can design myself.

I redrew the PCB so I could use expresspcb.com Miniboard service (3 boards for $50).
I'll gladly send you the file (they won't take the author's perfectly good Gerber file) once I make sure my redraw works.
You might want to email Brian (the author) as he was working on generating more boards as well. He's been super helpful to me.Posted by WrenchingPilot on August 20, 2008 at 18:07:12 Pacific Time

Hi I'm a newb at this and was wondering if you could email me the file to send to expresspcb.com to get the boards. Thanx for your help. Or if anyone can send me an eamil of any help involving obtaining these this board that would be great.

Hi all,
i'm interested in several of the boards and will go in with others, or would love the schematic to the new board. you can email me at jeff@livablestreets.info
thanks!

- PCB?

I'm finally getting around to doing this project, and was curious if anyone wanted to sell me the PCB or go in on a group buy.
Thanks

I hope this idea hasn't died - I'd like to buy a couple of them.Posted by phillipmilks@netzero.com on May 29, 2008 at 11:57:04 Pacific Time

Sounds like a good idea to me, count me in. Where were you thinking we'd go? I've used PCB Express in the past.
