(24 white SMD leds, no mask)

(As it is, this mask has 32 segments)<p>I did start design on a circular LED assembly once, allowing various configurations (multiples of 3, 4 and 5, specifically) and an open center (space for uC, rotary encoder, etc.) to be soldered by hand, but never finished it. My backlight just died, so I'm not likely to finish it now, either :) Getting it manufactured in quantity would be a bigger challenge.. Soldering teensy SMD LEDs by hand gets tedious. Maybe once things are up and running again.</p><p>There's probably some cheap 12-LED watches available for cheap somewhere that you might be able to yoink the display from, too.</p></p>

Is it possible?</p>

Just the whole board is zig-zag shaped like <a href="http://www.google.com/imgres?hl=en&safe=off&client=firefox-a&hs=cUg&tbo=d&rls=org.mozilla:en-US:official&biw=1280&bih=582&tbm=isch&tbnid=p_7L1soqrkAJQM:&imgrefurl=http://dangerousprototypes.com/docs/Get_your_PCBs_made&docid=2lMSeUaBU9nccM&imgurl=http://dangerousprototypes.com/docs/images/thumb/8/86/Pcb-via-misaligned.jpg/250px-Pcb-via-misaligned.jpg&w=250&h=125&ei=srXcUK-dBOHa2AXThIGIDw&zoom=1&iact=rc&dur=371&sig=108370741578925326930&page=1&tbnh=100&tbnw=200&start=0&ndsp=18&ved=1t:429,r:0,s:0,i:87&tx=113&ty=60" rel="nofollow">this pcb</a>.</p>

If there are pcbs with the zig-zag<br>
kind of hole arrangement, please let me know.</p>

For example, make a temp gague or something, and as it heats up colors shift from blue to green to yellow to red to flashing or other silly things like that.</p>
