Lee Peterson ☛ How to improve wearing a NATO strap
By simply cutting off the under keeper and using a match to seal the edge you remove the extra nylon and then you just turn it into a single pass as you can see in the image above.

Arduino ☛ This miniature monorail stays upright with the help of gyro stabilization
Hyperspace Pirate took advantage of that fact to create a shrunken-down version of the 20th century experimental monorail that travels along a 24″ track. It uses a control moment gyroscope (CMG) to keep the car upright on the single narrow rail. A CMG like this one uses a spinning mass’s inertia to resist torque that would change the axis of rotation. If you’ve ever played with one of those gyroscope hand exercise balls, this works in a similar manner. This monorail utilizes two of them to counteract side-to-side tipping, while cancelling out the tendency of them to reduce forward-backward tilting.

Hackaday ☛ Hardware Bug In Raspberry Pi’s RP2350 Causes Faulty Pull-Down Behavior
The newly released RP2350 microcontroller has a confirmed new bug in the current A2 stepping, affecting GPIO pull-down behavior. Listed in the Raspberry Pi RP2350 datasheet as errata RP2350-E9, it involves a situation where a GPIO pin is configured as a pull-down with input buffer enabled. After this pin is then driven to Vdd (e.g. 3.3V) and then disconnected, it will stay at around 2.1 – 2.2 V for a Vdd of 3.3V. This issue was discovered by [Ian Lesnet] of [Dangerous Prototypes] while working on an early hardware design using this MCU.
