Hackaday Design Contest

[Darren] built a clock that uses a resistor to display the time. Well, it really uses a model of a resistor. This extremely tardy entry in the Hackaday design challenge houses all of the electronics on a PCB the size of a business card. Four RGB LEDs shine up through holes in the wooden base to light bands on an acrylic tube. The colors correspond to the values used in the Resistor Color Code. In the picture above the clock is displaying 5:26 (that’s supposed to be a red band but the camera didn’t pick it up too well). The band in the center fades up over 60 seconds to signify AM, and down to show PM.

It may be late, but it’s a clever design. It looks sleek and it uses no buttons for an interface. [Darren] sourced the LEDs themselves as light sensors to display the date, and enter time setting mode.

So, you guys want to show off your skills? We’re giving you the chance. [If you don’t like it, blame Limor – she came up with the original idea]

The Challenge:
Design our next give-away: a business card sized PC Board. We’re not telling you what to make the circuit do, just make it something handy for hacking. Me, I think a PIC programmer/proto board would be handy.

The board must have:

The Hackaday logo
business card dimensions (90mm x 55mm)
reasonably easy to construct
A useful circuit (programmer, interface, whatever.)
Assembly instructions
Parts list

Through hole components are a good idea (Of course, if you can do it with SMD cheaper, and keep it easy to build… Surprise us) Maybe we could surface mount the CPU before we give them away, or we might put together parts kits, but it depends on the winning design(s).

You can put whatever circuit you like on it. PIC
programmer, JTAG interface, flux capacitor… but it has to work!

We want to have a board house make these up for us, so we’ll need the design in a format we can work with. We suggest EAGLE. It’s free and runs on just about everything. (But it limits you to two layers – which should be plenty)

Some hints to help you get the winning design:
Bonus for extra functionality
Clever incorporation of our logo
Completeness – include solder mask, drill info, everything we need to make the board.

The Prizes:
Fabienne is putting up her black 2gb iPod nano engraved with “hackaday.com” “one fresh hack each day” – It’s been used a bit, and opened up a few times so it’s got some scratches, but hasn’t been modded… yet.

We’ll send you some of the boards of course. I’ve got more good stuff in the works, and I’ll announce more prizes as we get them confirmed.

Submissions: When you’ve got your design ready, Put it online and let us know about it on the tip line. (Or send in a tip and we’ll tell you where to email it if you don’t have anywhere to host it.)

The Deadline: December 25th. Plenty of time to get your design cranked out. Everyone needs a winter break, but We’ll try to have a winner chosen within a week or two of the deadline.
