Sprig Is An Open Source Handheld Game Console
[Hack Club] is a group that aims to teach teenagers about tech by involving them in open-source projects. One of the group’s latest efforts is Sprig, an open-source handheld game console, and [Hack Club] has even been giving them away!

Ultrasound levitation soldering kits will be present at OpenFest for soldering workshop
Sound travels approximately at 343 meters per second. When two speakers are placed opposite one another and they generate sound with same phases, then acoustic standing sound waves are formed.

Odroid N2L Takes Aim at Raspberry Pi 4
Now smaller than a Raspberry Pi 4 (opens in new tab), the Odroid N2L makes a fine alternative if you don’t mind that there's no Wi-Fi, Bluetooth or Ethernet. Its six-core processor is made up of four Cortex-A73 cores which at up to 2.4GHz are faster than the 1.5GHz quad-core A-72 model in the Pi, and adds a couple of A-53 efficiency cores too, plus a Mali-G52 GPU. RAM comes in the form of either 2GB or 4GB of LPDDR4 running at 3216 MT/s, and there's both an eMMC socket and Micro SD card slot for storage.

Students Build Supercomputer From Jetson Nano Kits
After receiving a small grant to create the Jetson cluster, it was built from scratch in four months by two students, who also created the acrylic casing, more than 60 of the interconnecting cables, and the power supplies by hand, learning about wire stripping, networking, and laser cutters along the way. (Only one small fire was started.) The computer began life as a collection of Jetson Nano modules spread across a desk, using cardboard boxes as "heatsinks," but was upgraded into the current neat acrylic casing using 3D vector files fed into the laser cutter at the university’s makerspace.

Tiny Computer, Huge Learnings: Students at SMU Build Baby Supercomputer With NVIDIA Jetson Edge AI Platform
“We started this project to demonstrate the nuts and bolts of what goes into a computer cluster,” said Eric Godat, team lead for research and data science in the internal IT organization at SMU.
Next week, the baby supercomputer will be on display at SC22, a supercomputing conference taking place in Dallas, just down the highway from SMU.

Raspberry Pi CEO Talks Pi Inventory, Next-Gen Boards
Update (11/10): A previous version of this story incorrectly stated that Upton expects the current shortages to continue for a year, rather than that he expects all stock issues to have been resolved by this time next year. "There’s a vast difference between feeling confident that we’ll be free of shortages in a year and feeling that there will be a year of shortages," Upton told us. To be clearer, this means that he expects the situation to improve over time and to be completely resolved within 12 months.

Using the Arduino IoT Cloud to dispense pet treats | Arduino Blog
Recently, one of Instructables user mikerobertgodfrey’s friends adopted a senior dog who experiences frequent separation anxiety, thus causing him to panic when left on his own. As an attempt to help, Mike decided to build an Internet-connected wireless treat dispenser that would accompany a pet camera for remote training.
The device was constructed by first taking various rectangular pieces of plywood an assembling them around a central hub to create a fan-like object with a total of eight compartments for treats. This component was then sandwiched between a solid wooden base and a covering plate of clear acrylic to prevent treats from falling out. Lastly, Mike attached a servo at the back in order to rotate the dispensing mechanism and also embedded an Arduino Nano RP2040 Connect board into the base.
