Hackaday ☛ Witch’s Staff Build Is A Rad Glowing Costume Prop
Let’s say you’re going to a music festival. You could just take water, sunscreen, and a hat. Or, you could take a rad glowing witch’s staff to really draw some eyes and have some fun. [MZandtheRaspberryPi] recently undertook just such a build for a friend and we love how it turned out.

Arduino ☛ An engineer’s journey to bring the ultimate TMJ pain relief tool to market
To the average person, invention and new product development seem like pretty straightforward processes; you come up with a killer idea, do the engineering work to cobble together a working prototype, have a truckload of units manufactured, and then sell those to turn a profit. But the reality is far, far more complicated than that.

CNX Software ☛ Olimex RVPC is a one Euro RISC-V computer kit with VGA and PS/2 connectors
Olimex RVPC is one Euro RISC-V computer powered by a WCH CH32V003 RISC-V microcontroller and equipped with a VGA port for video output and a PS/2 connector to connect a keyboard. You won’t be able to do much with this device as an end-user, but it does not matter since the RVPC open-source hardware board mostly targets the education market and is offered as a kit to be soldered to lower the selling price and to serve as a soldering learning kit.

Raspberry Pi ☛ It's all hands OFF deck with this Pi-powered LEGO card shuffler
Louis used a LEGO Spike education kit with Raspberry Pi’s LEGO Build HAT to create a simpler but more robust design. The kit includes cycle motors, which he attached directly to the Build HAT’s four connectors. “The Build HAT made it pretty easy to pick up all the motors and plug them in.” He then programmed Raspberry Pi 4 over SSH, “which made it easy to tweak code.”

Arduino ☛ Marble art madness from a marvelous machine
The mechanisms all work in concert to drop the marbles into the display area, creating images of 32×32 pixels (1,024 “pixels” in total) and up to eight colors. The machine can automatically reset itself and then display a new image, so it can keep going indefinitely while spectators watch the intricate dance play out.

SparkFun Electronics ☛ Understanding Odometry and Its Applications
Think of odometry as the GPS for robots and autonomous vehicles, but without relying on satellites. It's all about using data from motion sensors to figure out how far something has traveled. By tracking these movements, odometry helps in calculating the relative position of the vehicle, which is for navigation and mapping.

Hackaday ☛ FieldStation42 - OTA TV Simulator
I started this project after noting how my enthusiasm and interest in television had changed over time. With a million streaming options, why was I bored with it all? Something feels heartless about it all and it made me wonder if the experience of TV had been better when I was a kid in the late 1970's and 80s. I decided to try and recreate the experience I had with TV back in the day. While my personal experiment focuses on my own experience in the late 70's and early 80s, the hardware/software described in this project can easily extend to any era of OTA broadcast television.

CNX Software ☛ Jumperless V5 programmable breadboard is based on Raspberry Pi RP2350B, features a built-in power supply (Crowdfunding)
Jumperless V5 is a one-of-a-kind, programmable breadboard based on a Raspberry Pi RP2350B microcontroller that lets you skip the jumper wires and jump right into prototyping. It is described as “an Integrated Development Environment (IDE) for hardware.” The Jumperless V5 also removes the need for test equipment as it comes with built-in power supplies and can function as a multimeter, oscilloscope, function generator, and logic analyzer.
