CNX Software ☛ DDR4 supply/demand stress leads to Raspberry Pi CM4/CM5 price increases
The price of DDR4 memory has increased dramatically in recent months due to limited supply and increased demand for Hey Hi (AI) workloads. The Raspberry Pi Compute Module 4 and 5 (CM4/CM5) are based on LPDDR4 memory, and Raspberry Pi reports that memory costs are roughly 120% higher than they were just a year ago. So they have no choice but to increase the price by $5 to $10 for the CM4 and CM5, as well as the Raspberry Pi 500 keyboard PC. I assume the $200 price tag for the Raspberry Pi 500+ mechanical keyboard PC released last week already includes this new reality.

Arduino ☛ This Arduino Nano R4-controlled hourglass simulates sand with LEDs
Outside of playing board games, hourglasses are almost entirely pointless these days. And yet, they’re still incredibly satisfying. Watching the sand fall in a steady and consistent stream is downright mesmerizing. Sadly, you probably can’t make your own hourglass unless you happen to be very skilled at glassblowing. But you can create this LED hourglass with sand physics instead.
