Hackaday Links: December 3, 2017

Remember the Psion? Back when PDAs were a thing, the Psion was the best you could get. It was, effectively, a palm-top computer with a real qwerty keyboard. It didn’t have Bluetooth, it couldn’t browse the web, and it didn’t have WiFi, but this was an AA-powered productivity machine that could fit in your pocket. Now there’s a new palmtop from Psion engineers. The Gemini PDA is basically a smartphone with a real keyboard that runs Ubuntu. It’s also has a smaller battery than other devices with this form factor, meaning the TSA thinks it’s a smartphone. This thing is going to be cool.

TechShop, Inc. has reached an agreement to sell the company to TechShop 2.0, LLC. New ownership seeks to re-open, continue running makerspaces. Details coming soon.

Arcade monitors are cool, and vector monitors are even cooler. [Arcade Jason] created a gigantic 36″ vector monitor. It’s thirty-six inches of Gravitar, in all its vector glory.

A few links posts ago, I pointed out someone was selling really awesome, really cheap LED panels on eBay. I got my ten panels, and [Ian Hanschen] bought sixty or some other absurd amount. Now, these panels are going for $300 for a 10-pack instead of $50. Sorry about that. Nevertheless, the reverse engineering adventure is still ongoing, and eventually, someone is going to play Mario on these things.

The ESP32 is finding its way into all sorts of consumer electronics. Check this thing out. It’s an ESP32, four buttons, and a circular display. If you want to make your own Nest thermostat, or anything else that needs an awesome circular display, there you go.

Speaking of circular displays, are there any non-CRT displays that come with a polar coordinate system? Every circular LCD or OLED I’ve ever seen uses a Cartesian system, which doesn’t really make sense when you can’t see 30% of the pixels.

Hold the phone, this is far too clever. [Eduardo] needed to flash an ESP-12 module before soldering it onto a PCB. The usual way of doing this is with an absurd pogo pin jig. You know what’s cheaper than pogo pins? Safety pins. Clever overwhelming.

For the last few months we’ve been running The Hackaday Prize, a challenge for you to build the best bit of hardware. Right now — I mean right now — you should be finishing up your project, crossing your t’s and dotting your lowercase j’s. The last challenge in the Prize ends tomorrow. After that, we’re going to pick 20 finalists for the Anything Goes challenge, then send the finalists off to our fantastic team of judges. Time to get to work! Make sure your project meets all the requirements!

It’s been a few weeks, so it’s time to start talking about Star Trek. I’m paying ten dollars a month to watch Star Trek: Discovery. I was going to pay that anyway, but I think this might actually be worth it. Highlights include Cardassian voles and Gorn skeletons. Also on the Star Trek front is The Orville, [Seth MacFarlane]’s TNG-inspired show. The Orville has far surpassed my expectations and is more Star Trek than Discovery. Leave your thoughts below.

It’s a new edition of Project Binky! Two blokes are spending years stuffing a 4WD Celica into a Mini. It’s the must-watch YouTube series of the decade.

AstroPrint now has an app. If you’re managing a 3D printer remotely and you’re not using Octoprint, you’re probably using AstroPrint. Now it’s in app format.

Have fifty bucks and want to blow it on something cool? A company is selling used LED display tiles on eBay. You get a case of ten for fifty bucks. Will you be able to drive them? Who knows and who cares? It’s fifty bucks for massive blinkies.

[Peter] is building an ultralight in his basement. For this YouTube update, he’s making the wings.

Oh it’s deer season, so here’s how you make deer jerky.

If you’re messing around with Z-Wave modules and Raspberry Pis, there’s a contest for you. The grand prize is an all-expense paid trip to CES2018 in Las Vegas. Why anyone would be enthusiastic about a trip to CES is beyond me, but the Excalibur arcade has Crazy Taxi, so that’s cool.

Go is the language all the cool kids are using. GoCV gives Go programmers access to OpenCV.
