> Today we’re going to be taking a look at the new ArduCam Time of Flight (ToF) Camera. This is a new camera by ArdCam that gives your Raspberry Pi 3D vision by adding an IR laser illuminator alongside the camera lens.

> A common problem among owners of multiple pets is how to feed them separately. If one animal needs special food, is on a diet, or likes to eat from another’s bowl, it becomes difficult to control each pet’s consumption. That is especially true when one pet doesn’t like to finish their bowl of food immediately and leaves it open to theft by another. To solve this problem and prevent one cat from stealing another cat’s special diabetic diet food, Tomas built a selective pet feeder.

> Like most of us would, Tomas first thought of using NFC tags on his cat’s collars to grant access to their food bowls. But NFC has a very limited range, which makes it hard to use in a situation like this. After considering other solutions, Tomas realized that one of his cats weighs quite a bit more than the other. If they were a similar weight then this wouldn’t work, but because the difference is substantial, he figured he could use a scale to grant access to the special diet food.

Raspberry Pi RP2040 gets into BBC Micro:bit lookalike board

> ELECFREAKS Pico:ed V2 is a Raspberry Pi RP2040 board heavily inspired by the BBC Micro:bit with an edge connector exposing rings suitable for crocodile clips, a 17×7 LED matrix display, and designed for the classroom.

> We’ve seen several BBC Micro:bit clones – or rather adaptations – over the years with boards such as the SiFive Learn Inventor, Elecrow Mbits, and HiHope “Big Brother” board. The Pico:ed V2 adds to the list, and the main differences are that it is based on the Raspberry Pi RP2040 microcontroller instead, and does not come with wireless connectivity relying on a USB interface only.
