All plastic 150W eBay desk mini-heater. (With schematic.)
I got this just to see what the safety features were like. There seems to have been a spate of mini heaters being sold that either plug directly into a socket or are designed to be placed on a desk for low level local heating. Most of the lower power ones seem to use PTC based heaters that self regulate around a small temperature range by increasing their resistance as they get hotter. I wondered what other thermal protection was present inside.
The unit seems to house a very standard looking heater module. It's quite neat that they've fitted it all into an optimal space. The replacement label on the box was wrong. The original data it was covering was correct for power and dimensions.
The fan isn't quite as quiet as the camera makes it seem. There seems to be noise gate that masks lower level noise.

What makes this ioniser unique is the dust collection mat that is charged to a high positive potential with respect to the supply to make it a preferential dust collection zone than surrounding furnishings.

Since Halloween is fast approaching I thought I'd take a look at two of Poundland's new products. The projector actually costs £5 and the strobe £2. One is not very good and one is very hackable indeed.

This unit is completely different from the other unit I looked at. It has different circuitry and a very odd optical system for the nebula effect.
Thanks to Christopher for sending the faulty unit for us to explore.
The manufacturer might be inspired by the video, as two of the optical components can be combined to give a really neat effect.

This light almost looks like it has been repurposed from other random components. It has three LEDs red, green and blue with lenses on them, a patterned disk with just a mass of random images, a set of rotating lenses and an outer layer of lenses too.
It projects a morphing mish-mash if images onto your wall or floor that continually move like a lurid kaleidoscope. It's quite interesting, and you can get different effects from it by removing layers of lenses.

By special request. Trimming the full bear back to a long goatee fast with a funnel and shaver.
Last time I recorded this I did it with a black short and got requests to do it again with a lighter colour so the resulting goatee is actually visible.
To do this you'll need a 4" (100mm) funnel and a good beard trimmer that is freshly cleaned and oiled.

A quick look inside one of the electrical boxes associated with some styles of street lighting, and the repair of the Sangamo time switch inside.
Also featuring the sudden disassembly of the more-complex-than-expected solar dial that compensates for differing hours of darkness throughout the year. (I did actually manage to reassemble it again after two goes.)
I'm not completely sure what component was missing from the box. I don't think it was a contactor, and the only convenient ballast to fit remotely in local street lighting is the older mercury vapour type with no high voltage ignition pulses.

This thing actually does disrupt molecules. By applying a high voltage to needle tips in front of oppositely charged rings it generates small points of electrical plasma that split air molecules into separate atoms, allowing some to recombine into short lived, but very useful active molecules like ozone.
This project is designed to be used with the cheap ioniser style power supplies on eBay, and will convert them to a mini "ionic breeze" type unit that blows a gentle draught of air out the front with active components that have beneficial effects in some indoor environments.
I made a video about ozone that explains more:-

Here are links to the PCB zipped gerber files. You'll probably have to copy and paste the links into your browser. YouTube might block links to zip files for security reasons.
It's two separate designs because the corners are rounded and PCB makers may not like two different PCBs being submitted as a single panel.
The main needle holding panel:-

The front plate with different text:-

I've since tested this module with mains voltage ioniser modules, and the differing module sizes give different levels of ozone output. If using the mains voltage modules I recommend using two 1 Megohm resistors in series with each wire for safety. Preferably 1/2W or 1W resistors for their higher voltage rating. It works very well with the 12V module I showed, which is effectively an ozone generator already with its two opposite polarity carbon fibre emitters. When used with this panel much more ozone is generated.

Apart from the very good heatsinking of the LEDs on this light, there is a very unusual feature in that the metal bodied USB plug can go in either way round.
I'm still pondering if I'll continue using this phone as my main camera. Comments welcomed.
Here's a general eBay search link for this USB light.

This light was sent by Miek (Me-Yack) after he bought it on eBay but wasn't sure about the wiring colours. In reality it's quite an odd arrangement. To get an earth/ground connection on the metal baseplate of these lights a separate earth wire and eyelet/fork crimp onto a case screw is probably best.
It's most likely the yellow wire is an override for the PIR sensor function. If you used a two way switch that toggled between the red and yellow wire it would switch between continuous-on and automatic mode.
The high apparent power when the light is off is due to the use of a simple capacitive dropper power supply for the circuitry that has to provide enough current to activate the relay. If your utility company charges for apparent power, as many can do with the smart meters, then it means this light could cost as much to run when it's off as when it's on. Not many utility companies do charge for apparent power yet, but it's going to be a thing in the future because.... profit.
