Who did fail to properly close the fridge (again)?

By martinm, in DIY and Programming, september 23,2022.

At Yoctopuce we have a small refrigerator that is used to keep the stock of solder paste, a few bottles of water and occasional picnics cool. We've noticed that the little flick of the wrist we all usually give the door isn't always enough to close it. It then stays open for hours before anyone notices. We suspect this is a result of the heavy water bottles stored in the door. We could probably solve the problem by slightly tilting the fridge with wedges, but a Yoctopuce overkill was much more fun...

Two years ago, we told you about reed switches, especially to warn you about the difficulties that you can encounter when you want to use them to build a rev counter. But we had somewhat forgotten to tell you about Hall effect sensors, which can be a welcome substitute.

A WiFi-driven LED aquarium lightning

Following an epic tadpole story that did not turn out as planned, four goldfish came into my house with their aquarium. The aquarium was second hand, so the lighting was no longer in working order. No worries, we will repair it in the Yoctopuce way...

A USB full-color scrolling LED display

By mvuilleu, in DIY, july 01,2022.

While working on our radar last week, we realized that it was a bit unfortunate that two Yocto-Color-V2 were required to drive a 32x8 LED display. Even more so, that we had just developped a custom device for a customer, capable of driving 512 RGB LEDs. Therefore, we decided to improve the situation by expanding the capability of the Yocto-Color-V2.

More and more sites require two-factor authentication via SMS. From a security standpoint, it's very good, but it can become bothersome if the login is shared by several people. This week, we are going to see how to receive an authentication SMS and to transfer it to several people.
