    looking forward to packing this 400x400x200 box with electronics and... trying to jam it in my suitcase?? wish me luck

    a 400x400x200 safety orange steel box. around it lie assorted medium-chunky DIN rail power supplies and a DIN rail DALI adapter

    so Project Illuminating Friendship is going well

    ordered a pair of 48V 240W DIN rail PSUs from Mouser to power friend's neat 48v/DALI track lights
    they arrived so crushed that the inlet chokes had completely broken loose from the boards. clearly damaged in the warehouse and then shipped

    it took 10 days and now I have replacements
    and they are also crushed. also clearly warehouse repacked because the boxes have damage in the wrong spots

    I am flying to my friend's far-away home in 10 days

    A view through the ventilation mesh of two DIN rail PSUs. A big transformer/choke core with the traditional yellow tape band is floating free at a weird angle in each case. The vent mesh is also a bit bashed in but it's hard to see from this angle

    ok mouser can't to a correction order on a correction order so I got a credit and ordered new ones from Digi-Key and they actually shipped me normal ones

    now to pack my largest suitcase,

    a large steel box in safety orange paint takes up almost the entirety of the volume of a big suitcase

    professor abrasive's light switch factory

    these are illuminated pushbutton mechs mounted to suit Hager Rotoloc plates. fairly standard 16mm industrial buttons, LEDs replaced with warm white, into a 2-parf press fit flame retardant ABS printed housing, JST connector to my DALI bus coupler

    a snake of chunky black housed pushbuttons each with a white button and a wire tail and connector
    stages of production; pile of industrial buttons, pile of wire tails, pile of printed shells
    stages of production; looks like wire tails are soldered and housings closed on buttons. there's a box of bus couplers too and a general sense of chaos
    soldering up LEDs and resistors to go in the pushbuttons. I'll always be grateful for things I learned working at Talking Electronics eg. blu-tac is an excellent soldering fixture. also a bread knife is best for cutting IC tubes

    bus couplers are housed too.

    these take up to 6 buttons and knobs - the max that will fit on an Australian wall plate - and map them to DALI input and feedback devices (the pushbutton status LEDs are "feedback")

    a small army of printed plastic housings containing one electronick each. each has four push in wire connectors so you can loop a Dali bus in and out on 1.5mm figure 8 / speaker wire. Six JST headers provide for connection to buttons and knobs. One is upside down showing a serial number and GS1 data matrix barcode

    I still need to mount rails in the box and wire up:

    - DALI PSU
    - 12V PSU
    - 2× 48V 240W PSU
    - fan controller
    - RPi with CAN and 12v input hat
    - DALI to CAN/USB bridge
    - terminal blocks and fuses for same

    and punch out a bunch of D-type cutouts on the box's gland plate for data, power etc.

    and then pack my clothes for this trip into all the nooks and crannies. and the other big present for someone else's birthday
