Redditor Goodolelubot made Harley Quinn’s mallet to go with his wife’s cosplay for SC Comicon last weekend. He said this is his biggest EVA foam build yet. He wrapped the material around an empty Quikrete tube to give it structure. Once he had the shape down, he used a dremel with a sanding bit to give the foam texture and cracks and knots to simulate wood grain. He says:
“Painting wasn’t too hard. Its just black primer/paint deep into every crack, then lightly brush painted acrylic over the top using minimal paint so it didn’t go into the deep cracks.”
You can see the unpainted version of the foam with the wood grain in the below picture:

First released in 1977, the Atari 2600 — or Atari VCS, as it was originally known — wasn’t the first home video game console. But it did help usher in a novel concept: having games stored on cartridges that you could swap in and out of the machine. These games were sold individually in stores, and the boxes lining retail shelves had to do a lot of the heavy lifting in terms of promotion. One of the earliest games to hit the Atari 2600 was Combat, which was not only part of the first wave of launch titles, but came packaged with the console for several years. It was also the first cover painted by Cliff Spohn, an artist who helped define the look of Atari box art early on. “I kind of approached them like a paperback book cover or a poster for some sporting event,” says Spohn.

“Get in the action with Atari!” Since its formation in 1972, Atari pioneered video game technology and built today’s multi-billion dollar industry, developing arcade games, home video systems, and personal computers to entertain millions of children and adults with fan-favorite games like Asteroids, Centipede, Missile Command, and Yar’s Revenge. To usher in the new era of electronic entertainment, the company hired an array of talented illustrators to emblazon game cartridges, boxes, magazine advertisements, and more with mind-blowing visions of fantasy and sports thrills, science fiction and adventure, that elevated pixelated gaming to the realm of high art. Art of Atari is the first official retrospective of the company’s illustrative accomplishments, spanning over four decades and cultivated from museums and private collections worldwide.
We arrived in Berlin yesterday from Dublin and I checked for events at makerspaces here. I found FabLab Berlin from Adafruit blog posts so I checked out their events. Tonight they had their weekly open house! Here is what I saw.

Awesome project tutorial from Team RWarrior up on Hackster.io.
We offer simple solutions that give individuals the key to producing their own food to feed their family and community. To create this little wonder, we took inspiration from the most effective permaculture techniques in order to regenerate the soil, and linked it with aquaponics (a symbiosis between fish and plants with vertical growing towers). Furthermore, to minimize our solution’s daily maintenance, we added Open-Source hardware that automates certain routine tasks.
Adafruit HTU21D-F Temperature & Humidity Sensor Breakout Board: It’s summer and you’re sweating and your hair’s all frizzy and all you really want to know is why the weatherman said this morning that today’s relative humidity would max out at a perfectly reasonable 52% when it feels more like 77%. Enter the HTU21D-F Temperature + Humidity Sensor – the best way to prove the weatherman wrong! (read more)
Last summer we installed new electric sunshades on our house. A few weeks later in the autumn we discovered they are quite wind sensitive and need to be protected. We could not let them down when leaving the house and also at night we had to be careful or stand up and raise them in all rooms as soon there was wind or storm.
This was the point when I decided to install a windsensor to control the sunshades. So the first thing was to find something that works well with our existing house automation system “Homematic”, which was not easy and every solution that I found was either expensive and/or not working well together with Homematic.

Pi Wars is a challenge-based robotics competition with Raspberry Pi-controlled robots – and its happening in Cambridge this weekend! Via Raspberrypi.org
On 1-2 April, Cambridge Raspberry Jam will be hosting Pi Wars 2017, the latest iteration of their successful robotics challenge competition.
For those unfamiliar with the setup, Pi Wars contestants use home-brew Raspberry Pi-powered robots to compete across seven challenge courses. There’s also a host of other categories, including prizes for Artistic and Technical Merit, as well as an award for ‘Funniest Robot’!
With only a few days to go until the big weekend, we’ve wrangled Pi Wars 2017 hosts, Mike and Tim, to give us the lowdown on everything you need to know before the main event.
This is the third time the competition has been run, and this time we’re running the event over two days:
Saturday – School teams.
Sunday – Beginner, Intermediate and Pro/Veteran teams.
With teams coming all the way from the USA, Germany, Switzerland, Wales and Scotland as well as England, it truly is an international competition! There are more than 65 teams competing across the weekend. Judging by some of the tweets we’ve been seeing, there’s likely to be some fierce competition!
Check out some of the action from the 2015 competition in the video below!

Recently I have been working on a project that would allow anyone to turn a Raspberry Pi into a universal remote. To do this I have been using LIRC (LINUX Infrared Remote Control), LIRC is a package that allows you to decode and send infra-red signals to many (but not all) commonly used remote controls. This project provides a starting point for experimenting with an IR LED and the LIRC package on the Raspberry Pi and extending the basic setup with new features and functionality, such as adding an IR receiver to generate a LIRC remote profile using an existing remote control.

Researchers at the University of Illinois at Chicago College of Medicine and Massachusetts Eye and Ear/Harvard Medical School have developed a cheap, portable camera that can photograph the retina without the need for pupil-dilating eye drops. Made out of simple parts mostly available online, the camera’s total cost is about $185.
“As residents seeing patients in the hospital, there are often times when we are not allowed to dilate patients — neurosurgery patients for example,” said Dr. Bailey Shen, a second-year ophthalmology resident at the UIC College of Medicine. “Also, there are times when we find something abnormal in the back of the eye, but it is not practical to wheel the patient all the way over to the outpatient eye clinic just for a photograph.”
The prototype camera can be carried in your pocket, Shen said, and can take pictures of the back of the eye without eye drops. The pictures can be shared with other doctors, or attached to the patient’s medical record.
The camera is based on the Raspberry Pi 2 computer, a low-cost, single-board computer designed to teach children how to build and program computers. The board hooks up to a small, cheap infrared camera, and a dual infrared- and white-light-emitting diode. A handful of other components — a lens, a small display screen and several cables — make up the rest of the camera.

This is the third iteration in the Handheld Linux Terminal project I’ve been working on for a while now. Like the others, the aim is to create a small, all-in-one computer that is both portable, and usable.
One of the main problems with the last version was that it took way too long to make, and some of the finishing wasn’t as good as it could have been.
However, this version takes a slightly different approach, to create a much more polished finished product. It also has a few more features, like HDMI out, wifi and bluetooth built in, and 50% larger battery capacity.
I call it the Zero Terminal.
N-O-D-E’s ‘Zero Terminal’ slightly reminds me of the HTC Dream or early iterations of the Droid phones by Motorola with their slider keyboards. The action looks pretty slick and the power button disguised in the camera viewport is very clever.
And I really dig the peek of the inside of the device:
The Pi Zero W in combination with the other tech crammed inside the case make for some impressive specs in such a small package:
And if you have the necessary peripherals, it could be a full-fledged GUI system as well:
PowerBoost 1000 Charger – Rechargeable 5V Lipo USB Boost @ 1A – 1000C: PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-sharing battery charger circuit, you’ll be able to keep your power-hungry project running even while recharging the battery! This little DC/DC boost converter module can be powered by any 3.7V LiIon/LiPoly battery, and convert the battery output to 5.2V DC for running your 5V projects. Read more.
PiTFT Plus 480×320 3.5″ TFT+Touchscreen for Raspberry Pi: Is this not the cutest, little display for the Raspberry Pi? It features a 3.5″ display with 480×320 16-bit color pixels and a resistive touch overlay just like our popular original, but this one is engineered specifically to work with the newer “2×20 connector” Raspberry Pi’s. The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top! Read more.

Check out the winners of the first Pioneers Challenge!
After months of planning and making, we’ve come to the end of the first cycle of our new digital making programme for teenagers: it’s time to announce the Pioneers winners!
We laid down the epic challenge of making us laugh. And boy, did the teams deliver. I can honestly say that my face hurt from all the laughing on judging day.

When the spell is pronounced correctly and understood by the Pi, it tells an Arduino to ‘shoot’ the spell out of the wand via an infrared LED. If the infrared receiver attached to the opponent recognises the spell, it sets off the TENS machine to deliver an electric current to the appropriate body part. Expelliarmus, for example, sets off the TENS connected to the arm, while calling out a successful Petrificus Totalus renders the opponent near immobilised as every pad is activated. For a moment’s rest, calling out “Protego” toward your own infrared receiver offers a few moments of protection against all spells aimed in your direction. Phew.
Serakirah Cosplay is a Guild Wars 2 aficionado and recently made a costume based on her warrior in the game. Her character dons the exemplar attire armor. Serakirah crafted the legendary sword Bolt to accompany the costume. The prop replica looks to be a few feet tall. To keep it at a relatively light weight, Serakirah kept the build simple. She used foam rubber, Worbla, and black Worbla to construct the foundation of the golden weapon. She added blue LEDs to give it a glowing effect.

Self-described “avid hacker” Adam Ringwood has taken realism to new heights by connecting his real car up to a game of Mario Kart 64, running on a laptop. The reading of OBD-II telemetry data from the car’s onboard computer is done by a Raspberry Pi and a PiCAN2 add-on board. The readings are processed and converted into control signals by the Pi and then transmitted to the laptop. The steering wheel controls the steering of the Kart whilst other events, for example from windshield wipers, headlights, brakes control other aspects of the game such as the ‘jump’ command.

Great new project + write-up from Matthew Wagner up on his blog Hackmypi. Via RaspberryPiPod.
A family member asked me to put a camera in our garage recently, and immediately I decided to use a Pi Zero. Back when I was interviewing for my current job, I was dabbling with the idea of making a wireless, battery powered IP camera that I was going to attach to my dog, and get some cool footage of my dog running around. I never fully finished that project because, at the time, giving the Pi Zero wifi involved either soldering on a wifi chip to the bottom of the Pi, or using the MicroUSB port. Also, at the time, battery powering a Pi Zero project was a bit outside my skillset.
Recently, with the help of Red Bear Labs, I was able to make a few of these IP cameras. I started the build back before the Pi Zero W came out, so this hardware guide is how to build one of these cameras on the Pi Zero 1.3. This project will be part 1 of a multi-part project, incorporating a few Pi zero’s, a Pi 3, some software and some hardware. Ending, hopefully, with a fully functional security system that notifies the owner when there is movement.
