Going through eBay recently looking for parts for a couple of CRT-based projects, I came across these DC-DC converters. Apparently rated from 45-390v DC output at 200mA, these should be ideal for driving some of the electrodes (focus, screen, grid) in a CRT. Above is the top of the board,
Compressed air is a rather useful power source, especially when all maintenance is done by the on board crew instead of by boatyards. Screwfix had a good deal on a 50L 3.5CFM air compressor, to save space this has been permanently mounted in a free space & air will be

With every piece of Chinese electronics I obtain, mainly Baofeng radios, they come with a Europlug-type power adaptor, and a universal plug adaptor for the mains. The charger units aren’t too bad, there’s a fair amount of isolation between the primary & secondary, and even though they’re very simple &
I received this USB supply with a laser module from China that I purchased on eBay. I have heard of these nasty copies of Apple chargers going around, but I’d never received one this bad with a piece of Chinese electronics. Model No. A1265, so definitely an Apple clone. Apparently
To accompany the previous two posts about hydraulic generators & their components, here is the actual generator unit itself. Rated at 8.5kVa 230v AC, this will providea mains supply while the narrowboat is away from her home mooring. This unit will be attached to the side of the hull in
