Group Buy: Monolithic Chipamp Enclosure

jimbo1968 · 11th January 2010, 07:52 PM

This thread is to gather interest and discuss, if there is interest a wiki page will be started.

The concept is a 4" cube of polished copper, milled out, 1 channel chipamp inside, sockets on underside, sitting on a black plinth.

The more realistic version is probably anodised aluminum in choice of colors.

The main group buy is for just the cube, and maybe a blank socket panel. Although sub-buys might emerge for other bits.

My thoughts for a plan are:
1) group effort to iterate design then produce drawing
2) obtain quotes for prototype and batch (group task)
3) choose supplier(s) considering postage etc.
4) get/check prototype for quality
5) order batch

I don't need to be the person placing the order, but I am willing. It might be the person who finds the local machine shop with a good price.

As far as estimating cost. so far all I've got is 4" cube of aluminum about £25

Bulk copper is about 10 times the price of aluminum by volume, so I won't be pursuing that.

I've posted a better design now in this thread Monolithic Chipamp Enclosure

No CNC milling required, just a lathe. Therefore should be pretty cheap, hence no need for group buy. Not that there was any interest
