What a great project - many thanks for the ideas.Make sure you get the 10Amp version of:- Digital Voltmeter Ammeter Display - anything more than 10 amps needs a shunt resistor and different wiring!!!! Here is my version- rather fetching in matt black and matt white I think.DC5-32V LTC3780 Power Supply Constant Voltage Step Up-Down Boost Module mounted on 8mm dowels to allow air flow under the board as well. Modern boards have their own heat sinks.I chose to forget the DIY 5V regulator and fitted :-DC/DC DC 12V/24V Step-down to DC 5V 5A 25W Power Buck Transformer.I made the vent slots on the top cover very much narrower(band saw blade width) to prevent anything falling though.

Here in the UK I could only get 4.5 X 9 X 1 bricks. So I used 2 bricks. The rear wall brick does not have a hole. The 2 center ones have a larger hole than the front brick.The torch hole was drilled so that it aligns at the bottom and front of the second brick from the front(one with a larger hole than the front) and aligned slightly towards the back.This generates enough swirling heat to get a 1/2" square rod glowing bright red.Many thanks for the idea.
