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.

Guiding a spotlight with rangefinders

By mvuilleu, in DIY, march 22,2024.

A month ago, we presented in this blog two products whose tests had proved quite successful: a small rangefinder that worked over 10m, and a small DMX512-controlled motorized spotlight. We thought we'd make a fun little project by combining them, and there's nothing like this kind of testing to see if a product lives up to its promise...

Communicating with DMX512 devices

By mvuilleu, in DIY, march 01,2024.

DMX512 is a lighting control standard widely used in theater and nightclub technology. It enables all kinds of stage equipment to be remotely controlled from a central console, simply via a long three-wire bus on which the spotlights are chained. But can a Yoctopuce module be used to access a DMX512 bus?
