For several years now, the Raspberry Pi Foundation has been marketing 7-inch screens into which you can install a Raspberry Pi (sold separately) to create an all-in-one system. At Yoctopuce, we even have several that we use every day to monitor various experiments. But when we stumbled across SeeedStudio's reTerminal, we were keen to test it out to see if it could be used as an alternative.
While shopping at one of our usual suppliers, we came across an intriguing gadget: AA batteries, with an integrated USB-C charging port and which promise a capacity of 1600mAh for a 1.5V voltage. We couldn't resist the temptation to buy a pack, just to check if an AA battery with an integrated charger really works.
YoctoHubs make it very easy to create DIY projects that are remotely controlled by a server. All you have to do is to provide a network connection and a power supply, a simple USB charger can do the trick. We recently asked ourselves the following question: all USB chargers are probably not equivalent in terms of efficiency, but up to what point?
We have been asked several times whether we were going to manufacture a color sensor, also known as a RGB sensor. To be honest, the answer is: "we don't really know". You are about to understand why: this week, we are going to interface the TAOS TCS34725 color sensor with a Yocto-I2C.
At Yoctopuce, we like to buy random sensors, just to check if we can make them work with Yoctopuce hardware. This week we chose the GY-US42V2 sold by Play-Zone.ch and referenced as a "SRF02".
