After taking apart a full automatic foam soap dispenser, I went online and hunted for a foam pump on its own. These pumps simultaneously pump soapy liquid and air together to create a continuous foam-soap on demand. I found just one listing on eBay with the pumps:- https://www.ebay.com/itm/264812164691 The total with shipping is currently $4.54. Lets see if he puts the price up. The construction is very typical for these. A three diaphragm pump with direct motor drive swash-plate style, and matching round rubber umbrella flap valves to make sure the air and liquid end up going through multiple meshes to whip it up into a mousse. The liquid I was using was a mixture of washing up liquid (dish soap) and water. About 1 part soap to 4 parts water.

Yeah seriously, I did actually get a batch of Cyberpussy PCBs made... It's just one of those things that seemed like a good idea at the time but caused so many complaints on my website that I took the project and kit down. The absolution button was a one-off and was inspired by the notorious Sisters of Perpetual Indulgence, a group of suspicious "nuns" that give out free sin vouchers. It's a button... You press it... It lights up... Your are immediately absolved of all sin. (Including all the really naughty ones.) This button is guaranteed to be equally, if not more effective than the catholic church as it is non judgemental.

These are really cheap and common devices on eBay, sold as toys for printing images onto thermally sensitive paper. This one came with several rolls including coloured paper and self adhesive label material. The printer can only print one colour, usually black, dictated by the paper itself. The app does allow printing of photos, and uses dithering to get rough shades of grey. Given the relatively low resolution, the images are surprisingly identifiable. The thermal printers are very minimalist and refined due to their widespread use in receipt and label printers. If you consider that almost every till has a thermal printer for ease of maintenance (no ink) and an absolute minimum of moving parts, then it makes them very cheap and available for items like this one. The printing is done by heating up the paper with a row of tiny resistors. When heated the thermally sensitive paper changes colour. Although the USB data lines are there, I plugged the printer into the USB port of my Chromebook and it didn't detect it. It may work with a PC.

In hindsight I'm thinking that there is possibly a risk that if the LEDs in the tap point for the charger circuit fail open circuit, then when the cell is charged and the charge chip tries to break the current flow then it will be potentially exposed to hundreds of volts and could fail, potentially letting the lithium cell continue charging until it too fails in a very overcharged state.... I have to admit that this is a very clever idea. It's a standard LED lamp with the addition of a lithium cell. In normal use it charges from the mains while lit, but in the event of power failure it will light up automatically, but only if the wall switch controlling that light is on. That basically means you can turn it on and off from the light switch even when there's a power cut. It does this by applying a small DC voltage to the lamps contacts and detecting if it is bridged. If the wall switch is off then no significant current will flow, but if it is on then current will flow through other appliances and circuits in the house and it will detect that and light. This does mean that it can only really be used in a single lamp holder on its own, and the switch can only be a simple one with no active electronics. My apologies for all the random noises. I filmed this at work and there were explosions and gunshots in the background. Some lights on part of the show also needed their positioning adjusted slightly, so there was some loud walkie talkie use too because I had the volume up quite high. (It's a very loud show.)
