Fiddly switch assembles for the footlights, before they are sealed inside weatherproof plastic.
The knots are because the heatshrink plastic sleeving won't contract to the cable width, but will close around the knots.
One set of knots is glued on, partly to simply the job, partly because I'm pushed for time, mainly because I'd lacquered the boards before I realised I needed a second knot.
The folding on the left of the board is the cable clamp, the plastic bit around the switch is to stop the heatshrink tube squeezing the button permanently down, and board is longer than you would think it need's to be because these boards are tiny and it must orientate correctly within the tube, and stay in place in use.

Velleman PMK 111 INTERVAL TIMER
A new generation of cheap lightweight plastic electronic technology that does not require silicon, but which is optically transparent and can be coated onto everyday objects would transform our world.
"Working collaboratively with industry is not only satisfying in that I see aspects of my work translate into real engineered products, but it provides inspiration for new avenues of research too. Roadmapping then allows me to critically assess how I should be developing my research portfolio and engaging with industry to maximise the likelihood of productive collaboration."
—Dr Andrew Flewitt
Imagine electronically updated food labels, computers embedded in our armchairs, even contact lenses linking us directly to the Internet to bring us into the age of plastic electronics. In this video podcast Dr Andrew Flewitt and Dr Robert Phaal both from the Department of Engineering and Scott White serial entrepreneur and CEO of Pragmatic Printing talk about the creative partnership forged between different parts of the Department of Engineering and outside companies that enable the technology and research in this area to be exploited successfully.

MEDITERRANEAN SEA (Feb. 09, 2011) - Electronics Technician 2nd Class David Bunch fires a M16-A1 rifle during a qualification exercise onboard USS Mount Whitney (LCC/JCC 20). Mount Whitney is the U.S. 6th Fleet flagship homeported in Gaeta, Italy, and operates with a hybrid crew of U.S. Sailors and Military Sealift Command civil service mariners.

This photo recorded March 10, 2020, after visiting Space Center Houston. We've driven past this Fry's Electronics half a dozen times in recent years and I kept promising we'd stop and get a photo, so I finally did.

Dirty Electronics Mute Synth custom modified by A.S.M.O. for Daniel Miller (The Normal / Mute Records).
Touch panels hardwired to pots and switches, 3 LFOs, one for each oscillator and feedback.
Low / band pass resonant filter with external voltage control input, self oscillates at full resonance.
Panel is covered in (warm) leatherette, nice!
After hours spent carefully reworking the ARM (it arrived with some pins bent inwards, which wasn't noticed until after reflow, where they held it up and all the other pins didn't touch the pcb) and many more hours spent going over everything to work out why it wasn't programming, it suddenly started programming! hurrah
BSR spectrum analyzer 10x9 LED panel and driver board-- love that LED panel-- need to get it talking again.

BuildBrighton is working on making a pseudo-theremin for the electronica DJs Evil Nine. It will be a MIDI controller that works by sensing arm movements using ultrasonic range finders.

Ribbon cable meant for a dual-row 0.100" connector has conductors every 0.050", the same as the fine-pitch connector on the WD-C2401P display. Two sets of "helping hands" and a fine-tipped iron yield this.
Here, showing what the wires leading off-board lead to: an "action" button, a 3-position power/mode switch, and a 9V battery clip.
The power/mode switch was a fun design element to put in - made me think of the "PRO 1 - OFF - PRO 2" switch on the venerable Mattel Electronics Football.
This one didn't work out of the box. Eventually I figured out the previous owner had installed custom attenuation on X and Z which I have removed and reverted to standard. Then I found impedances were still off and I couldn't drive test 1V into X, Y and Z simultaneously. Turned out they had swapped X signal and signal ground versus schematic. I'm undoing that at the PCB connector level so as not to cause more confusion later.
I couldn't get hold of a precision shunt resistor, so I had to do with this 10% 5W one here. It didn't turn out too bad at all. This one doesn't affect the current displayed on the power supply's display (the display measures the current itself), but the current set-point in the opamp feedback loop. I have a schematic, but it is not quite matching the PCB revision I have, so I couldn't instantly figure out which pot to tweak to compensate for small deviations. Reverse engineering a schematic from a given PCB sucks.
I compared the current set on the power supply (via a keypad) and the current measured by a good multimeter and it wasn't off by more than 5% worst case. That's good enough for me right now.
