Another batch of PCB etched

As did all the shopping etc for xmas happy to put my feet up. And whilst doing that made up some new etch and used a new digital thermometer to check the bath is at 50 degrees C. The etch was really fast this time.

Just finished drying off the latest batch of PCB and what I especially like is no yellow/brown stains on everything. The solution turns a little blue/green, probably from the marker /cd pen I used. The boards are naturally yellow/green

These are top left; a N3ZI LCD display controller boards, top right; a Freakin' Beacon controller, bottom left; KD1JV (see earlier post) and botton right; one of the RD16HHF1 Mosfet PA boards (sea earlier post).

Whilst waiting for the etch I melted a little solder for a couple of N6BM projects, the Miniboots II PA and an LC Meter. The LC meter design is actually from MARC VK3BHR LC Meter Project - Mk.II but Wayne had reworked the PCB layout. I have a nice desktop calculator style case that one will go into.
