'Simple' Constant Current Load (3): Front Panel Assembling and Wiring

Just putting in all the front panel stuff and wiring it up …
↓↓↓ Complete description, time index and links below ↓↓↓

Before starting to prototype the actual circuit I wanted all the front panel stuff to be assembled and wired, so I wouldn’t have too much chaos around the breadboard.

Really nothing too exiting – well, I managed to crack the case of the 10-turn potentiometer and get its wiring wrong, all in one sweep.

Introduction …
00:00 Intro – let’s put all the components into the front plate
Assembly …
00:24 Panel meter frame –not its innards, otherwise it won’t go in
01:26 Binding posts – just fastening them with a nut
02:59 LEDs – just snapping them in, how convenient
03:55 Switches – also snapping them in, it’s so easy
06:10 Potentiometer – fastening it with a nut and killing it in the process
11:17 Panel meter innards – the frame is already in
13:20 Battery connector – plus some strain relief of course
14:42 Negative binding post – needs some wire added to it
Wiring …
15:45 MOSFET drain to positive binding post – avoid heating the PCB
17:36 Instrument to positive binding post – plus my wiring philosophy
18:56 Positive binding post to board – for the reverse voltage protection
20:37 9V consumers to power switch – instrument, LEDs and board
21:53 9V battery positive to power switch – enough said
22:09 Random wires to the board – a whole lot of them
23:10 Ground wires to the board – only two of them
23:57 9V battery negative to board – I’ll need that too
25:13 Negative binding post to board – can’t do without that
25:17 Potentiometer and range switch – controls everything
27:32 Headers to (bread)board – a matter of convenience
Wrap-up
30:38 Wrap-up – it starts to look like something and lights up

I always enjoy putting the bits and bobs on the panel...I look forward to elecy design phase!
