Upcycling an old fan

By mvuilleu, in DIY, Internet of Things and Measures, september 27,2024.

Almost ten years ago, we showed you how to combat humidity in a room using humidity-controlled ventilation. The system described had just then been installed in a cellar, where it worked efficiently until very recently. Unfortunately, the discovery of mold alerted us to a problem, and a quick check revealed that the system had broken down: the fan controlling the air intake had died.

A decorative IoT and PoE lamp

To tell you the truth, this week we had planned to continue our series on USB batteries, but it turns out that the associated experiments are taking longer than expected. Actually, this is rather good news, but this also means we had to fall back on an emergency topic...

RFID and key management

By martinm, in Programming and DIY, may 23,2024.

In the past, we've been asked several times whether it was possible to build a key management system based on Yoctopuce modules. Of course, we're talking about keys for opening locks, not cryptographic keys. We did propose a modest project a few years ago, but with the arrival of Yocto-RFID-15693, we can think bigger.

Who's let their coffee get cold (again)?

By martinm, in DIY, may 03,2024.

Yoctopuce has a self-service coffee machine. To get a coffee, all you have to do is walk over to the machine, place your cup underneath, press a button and wait. This wait can sometimes be a little long, because the machine has to grind a dose of coffee beans and possibly heat up if it hasn't been used for a few hours. It therefore happens quite often that the "customer" goes off to do something else while waiting, and forgets to come back for his coffee, which will be found cold by the next "customer". To put an end to this rather dumb waste, we've found a solution thanks to the brand new Yocto-RFID-15693.

A macro keyboard, Yoctopuce-style

By Tiago, in DIY, april 12,2024.

Some time ago, we presented a method for driving Yoctopuce modules with an Elgato Stream Deck. Today, we're showing you how to create a macro keyboard, inspired by the Stream Deck but based on a Yoctopuce module.
