Dead Buguino

I wanted to play around with wire wrapping and recently discovered a technique called dead bug. You basically glue your components upside down to something with all the legs sticking up in the air so it resembles a dead bug. So I picked up a wire wrapper and some wire, put some buttons together and put some leads on my replacement lcd, then hotglued everything in place (using the pcb prototype as a rough guide), leads up, and got wrapping

Note: I added a P4 compatable programming header so I can reflash it in place.

That's super cool. (The name "dead bugging" adds the "super" part.)

OT: just realized the display maxes out at 99.9 mpg... Oh no!

Nope, it drops the decimal over 99.9 so max display is 999 for big numbers, 999999 for normal sized numbers.

In my experience, that works great for one-way projects. If, however, you want to replace a blown chip, you have to completely rebuild that portion. But, yes, a cool method.

Thx, took my time. Maybe 2 hours. Would be challenging to repair a blown chip, but salvage is easy enough. The nice thing about it is the wire management, with the little built in stripper, and the attaching tool holding onto the wire, makes these short connections pretty easy. Problem is you need a bit of lead length, so wirewrap works great with dead bug style, but the standard chip leads are not long enough to wire wrap through some proto board.

I have come up with a strategy for small solid wire that works pretty well, basically strip a long length of it before you start, hanging on th the copper and the insulator. Then solder one end, hold the insulator over the route the wire will go and cut it at the next connection, hold the insulator next to the wire and cut the copper a little longer, then slide the piece of insulator back on the wire and mash the wire into place and solder the end. There is probably a name for that approach too

They make chip sockets designed with long leads for wire wrap projects.

I know I just have developed enough confidence in the current arrangement over time that thought dead bug would be fun.
