The MeArm Pi is a fantastic little robot kit that was the first place winner of the Enlightened Pi contest here on Hackaday. It’s crushing the Shitty Robots subreddit, and compared to the old MeArm kit, it’s much, much simpler to assemble. Ask me how I know. Now the MeArm Pi is a Kickstarter. This tiny robot arm is programmable in everything from Scratch to Perl. It’s highly recommended for children ages 8 to those wanting to recreate the opening scene of Pee Wee’s Big Adventure.

Almost a year ago, Lulzbot unveiled their latest 3D printer at the Midwest RepRap Festival. The Taz 6 is a great printer, but it’s a bit of a departure from their previous designs. The biggest change was the ‘brain box’, the controller box that encases the power supply, stepper drivers, and other associated electronics. Last year, Lulzbot said they would be selling this brain box by itself. It’s out now, ready for integration into your own self-built Taz, or a 3D printer of your own design.

Speaking of the Midwest RepRap Festival, it’s only a month away. It’s scheduled for March 25-26th at the Elkhart County 4-H Fairgrounds in Goshen, Indiana. Why the middle of nowhere? It ensures only the cool kids make it. For one weekend a year, Goshen, Indiana turns into the nexus of all things 3D printing. Don’t ask questions, just come. It’s free, although it would be cool if you kicked a few bucks over to the organizers.

[Clickspring] — the guy who built a fantastic clock in his home shop – is working on his second project. It’s an Antikythera Mechanism, and the latest episode is about building a gigantic gear. This is a unique approach to building an Antikythera Mechanism. [Clickspring] is still using modern tools, but he’s figuring out how this machine was built with tools available 2000 years ago.

Ogopogo. Champ is a picture of a log and Nessie is a toy submarine with a head made out of plastic wood. Ogopogo is a plesiosaur. Are you going to tell me a log – or at best a beaver – can kick the ass of a plesiosaur? Ogo. Pogo. Plesiosaur. The Travelling Hacker Box has conquered Ogopogo.

The ESP32 is quickly becoming the coolest microcontroller platform out there. You know what that means – Kickstarters! The FluoWiFi is Arduino-derived dev board featuring the ESP32 for WiFi, Bluetooth, and all the cool wireless goodies. This board also features an ATMega644p — basically the little sister to the ATMega1284p – for all your standard microcontroller Arduino stuff. It’s £25 for a board, which makes it pretty inexpensive for what you’re getting.
