The boards I received in the mail, about two inches long by one-and-a-half wide.
I built a prototype. Then I designed a PCB. This weekend I received a set of my very first custom-designed circuit boards. It’s quite a thrill to hold an item manufactured to your own specifications. Best of all, I ordered two, but was sent four. Thanks to BatchPCB for their generosity in this regard. Very nice. I designed the board using the EAGLE circuit design software on my MacBook, which had a weird learning curve but isn’t too bad to use. Once I complete testing of the boards, and make any necessary tweaks to the designs, I’ll post the EAGLE files here for anyone who’d like them.
I still have to order some parts to populate these boards (almost all SMD), but I have code ready to test these things out. Once the code is a little more polished, I’ll make that available too. Exciting days ahead!
It all seems clear to you but it ain’t to me. What are you going to do with these?
Sorry, I thought that was clear from an earlier post

I want fine-grained control over lots and lots of LEDs. I want working traffic lights and signaling, and interior lights that only come on at night. I want to simulate the weird glow that the insides of electronics shops have, from all those TVs going at once. That sort of thing.
Yeah. I thought about your LED ambitions but your recent Super Hitachi adventures confused me.
And where are you going to use all these? It’s a long time you didn’t gave us news of Akihabara.
Soon, soon. I have but one desk, and Shogatsu is currently consuming all of it. I’m gonna take it back to the basement for storage (after making a video, of course!) and then I can get back to the business of building Akihabara Station.
Sounds promising.
