$AliExpress unbagging joy with fake lego and hotel stuff - VOLUME ALERT! Another Santa-sack of technical goodies from AliExpress for us to explore. Here are some links to the items on AliExpress (not a sponsor). These are affiliate links, but that will not affect the price you pay. Keep in mind that these products may not meet your countrys standards. Single ended cut to length LED filament:- https://s.click.aliexpress.com/e/_c4kBOIiV Cost about £1. Solar car light thing:- https://s.click.aliexpress.com/e/_c4l9Bnod Cost about £2. Fake lego portaloo portable toilet. This is apparently referred to as an MOC (My Own Creation) and is generally more fun that official models, and a tiny fraction of the price:- https://www.aliexpress.com/item/1005004572701012.html Cost about £3. Real lego has a slightly dark history. https://en.wikipedia.org/wiki/Hilary_Page Water level sensor module (Ive not explored it yet.):- https://s.click.aliexpress.com/e/_c3KSo6FX Cost about £2. UVC toilet steriliser. Ive made the video - its totally fake, but will make your toilet look very futuristic:- https://s.click.aliexpress.com/e/_c2z6dZPL Cost about £3. The intriguing glass vehicle bulbs that I tested in arcade buttons:- https://s.click.aliexpress.com/e/_c3RUv0cD Cost about £2 for a pair. Im about to order a blue version of this bulb so we can see the construction with the bare chips. High voltage module:- https://s.click.aliexpress.com/e/_c30656qV Cost about £2. As mentioned in the video the quoted output voltage is fake. Sharp electrodes will spark at around 1kV per mm due to ionisation. NEVER operate these modules with the output wires more than 20mm apart, as the high open circuit voltage can destroy the internal circuitry. Pimple hydrocolloid patches:- https://s.click.aliexpress.com/e/_c4NdiUch Cost about £1.20 for loads. German parking timer disk that cheats:- https://www.aliexpress.com/item/1005008806388282.html Cost about £3. Hotel grade programmable 500ml capacity oil diffuser for creating a controlled ambient aroma:- https://s.click.aliexpress.com/e/_c3UaFpAZ Cost about £30. I also got some Weston hotel white tea aroma oil and even on the lowest setting this unit is far too powerful for a small home. The place experiences explosive bursts of intense bergamot aroma. You can buy small USB rechargeable home aroma units for just a few pounds, and bottles of their own aromas for about £2 that can be refilled with something of your own choice. Note that thicker essential oils can be watered down with very light volatile mineral oil. Larger venturi units are used by theme parks to give a characteristic aroma to themed attractions. They are terrible to refill and maintain because you end up getting the aroma oils on your hands and clothing.
