Finished building my self-made low-cost exposure unit by using a Tchibo TCM facial tanner an a Plustek OpticPro UT12 scanner. Both were second-hand and arrived yesterday. There are ebay auctions with exactly these devices.
For some reason one lamp doesn't power on correctly but my pimped scanner looks good somehow :-)
It will be tested on Saturday while I'm preparing the famous etching and soldering workshop
