Yes it still happens. Someone was having a problem with computer / server fans. These things can get insanely loud, think vacuum cleaner on maximum power. Some of the 40x40mm models spin up to 6000 rpm. Absolutely not an issue if servers are rack-mounted in a server-room, but if you like to keep one of those machines in your personal space, that is a big no-no. I was asked if I could build a little something that would measure the tacho-signal of the slow-spin-fans and scale that up to values that match the signal from the previous fans, fooling the hardware-monitoring, making it believe everything was ‘as usual’.

This particular model is not cheap ($399), but the extra resolution and features of the “Premier” series scopes are handy.
(which I have not used myself but gets generally positive reviews). Here’s a sample image from the AM4113T (converted to jpg but otherwise unmodified): The included Dino Capture software is surprisingly usable and allows you to take instant snapshots and videos and make a number of measurements and annotations directly within the tool (only supported on the more expensive Premier series).

Maker tips: I continue to be impressed by Gar’s Tips & Tools, a newsletter that we co-publish with Gareth Branwyn. I got a big bump in subscribers after this. For years, I saw other people, like my pal Kent Barnes, recommending alignment dots for mindlessly mating a jack to a plug without having to align the exact location or figure out the plug orientation. One of the most-requested projects I get asked about are DIY rolly cabinets for storing portable parts organizer cases, popular among makers.
Several weeks ago, I got a message from a subscriber saying that they couldn’t believe I hadn’t written about Tim Hunkin’s latest series, The Secret Life of Components.
