All of my attention has been on a new project, but I did just order PCBs for the second round of LED taillight prototypes. This one has been cut down a bit and has a second set of mounting holes so that it can fit either series 2 or series ...

My other Lambretta project:
(A bit fogged from letting wet superglue cure in an enclosed space. Oops.)
The prototype is good enough to use but needs to be revised. It's bright, it doesn't flicker, and it uses about 3-5W max so the headlight doesn't dim when you step on the brake at ...

I've been done with the first speedometer prototype for a few weeks now, so it's time for a tiny follow-up post. Short version: it rocks! Clear, readable, accurate, useful, gets comments. So far, it hasn't skipped a beat even with all the vibration from the TS1.
The thing on the left ...

I spent almost the entire weekend plus Monday in the garage. I think I knocked out most of the projects that have been lurking on the to-do list for a while now:
In the garage:
made 2 sawhorses
made a big, sturdy 8'x2' workbench (cost: $50 worth of lumber). You could park a ...

There were a few snags, but no show-stoppers. Damn, those 0603 parts are tiny.
The backlight turned out better than I had ever dared to hope, and the warning light is BLINDINGLY RED. Which is good, considering the things it will be warning you about.
I have no idea if the inputs ...

My day is shot. The boards came in the mail today. I ordered two, and they sent SIX. The LCD fits, everything lines up... so far, so good. Incredible service from SparkFun/BatchPCB!
Ohhhh, so happy. :)

Fortune smiles upon me! I got an email from SparkFun today saying my PCBs are done and in the mail. That's 9 business day turnaround from BatchPCB! I don't know what happened to the poor bastards on the forum, but it sure didn't happen to me.
Of course, now that I'm ...

I got a box in the mail from Pololu this afternoon! These laser-cut faceplates look pretty nice. They're thicker in person than they were in my head, but they fit perfectly.
All of the electronic components and screws and stuff have been here since last week, so the only things I'm ...

No, not that game of Life. Make's game of life kits were all over the blogs yesterday, which gave me an idea (and wasted an hour or so of my life).
Go go Nokia 3310 LCD. Framerate on this "game" is about 3fps because it is optimized for ease of coding, ...

It's been a few days since my last post because I've been elbow-deep in painting a spare bedroom and designing a top secret project for my Lambretta.
These are drawings of the faceplate and the printed circuit board for a digital speedometer for Series 3 Lambrettas. It will show speed, distance, ...
