HackSpace magazine 2: 3D printing and cheese making

via Raspberry Pi

After an incredible response to our first issue of HackSpace magazine last month, we’re excited to announce today’s release of issue 2, complete with cheese making, digital braille, and…a crochet Cthulhu?
HackSpace magazine issue 2 cover

Your spaces

This issue, we visit Swansea Hackspace to learn how to crochet, we hear about the superb things that Birmingham’s fizzPOP maker space is doing, and we’re extremely impressed by the advances in braille reader technology that are coming out of Bristol Hackspace. People are amazing.

Your projects

We’ve also collected page upon page of projects for you to try your hand at. Fancy an introduction to laser cutting? A homemade sine wave stylophone? Or how about our first foray into Adafruit’s NeoPixels, adding blinkenlights to a pair of snowboarding goggles?

And (much) older technology gets a look in too, including a tutorial showing you how to make a knife in your own cheap and cheerful backyard forge.

As always, issue 2 of HackSpace magazine is available as a free PDF download, but we’ll also be publishing online versions of selected articles for easier browsing, so be sure to follow us on Facebook and Twitter. And, of course, we want to hear your thoughts – contact us to let us know what you like and what else you’d like to see, or just to demand that we feature your project, interest or current curiosity in the next issue.

Get your copy

You can grab issue 2 of HackSpace magazine right now from WHSmith, Tesco, Sainsbury’s, and independent newsagents. If you live in the US, check out your local Barnes & Noble, Fry’s, or Micro Center next week. We’re also shipping to stores in Australia, Hong Kong, Canada, Singapore, Belgium, and Brazil, so be sure to ask your local newsagent whether they’ll be getting HackSpace magazine.

Alternatively, you can get the new issue online from our store, or digitally via our Android or iOS apps. And don’t forget, as with all our publications, a free PDF of HackSpace magazine is available from release day.

That’s it from us for this year; see you in 2018 for a ton of new things to make and do!

3D-printed miniature roller coaster powered by Arduino Mega

via Arduino Blog

While many enjoy roller coasters, few can claim the same dedication of engineer Matt Schmotzer, who 3D-printed a 1/25th scale replica of Invertigo, a boomerang coaster at Kings Island in Ohio.

As reported on 3D Printer Chat, the CAD model took only a week to complete, but 3D printing this 4’ x 8’ creation took an incredible 450 hours. This doesn’t include the countless hours spent assembling and debugging it.

The coaster runs on an Arduino Mega, using 42 of the 54 available IO pins. This allows it to not only lift and drop the coaster, but also feature details like actuated gates and restraints to keep the tiny imaginary passengers safe.

Be sure to check it out in the video below!

Ultimate 3D printer control with OctoPrint

Control and monitor your 3D printer remotely with a Raspberry Pi and OctoPrint.

3D printing

Whether you have a 3D printer at home or use one at your school or local makerspace, it’s fair to assume you’ve had a failed print or two in your time. Filament knotting or running out, your print peeling away from the print bed — these are common issues for all 3D printing enthusiasts, and they can be costly if they’re discovered too late.

OctoPrint

OctoPrint is a free open-source software, created and maintained by Gina Häußge, that performs a multitude of useful 3D printing–related tasks, including remote control of your printer, live video, and data collection.

Control and monitoring

To control the print process, use OctoPrint on a Raspberry Pi connected to your 3D printer. First, ensure a safe uninterrupted run by using the software to restrict who can access the printer. Then, before starting your print, use the web app to work on your STL file. The app also allows you to reposition the print head at any time, as well as pause or stop printing if needed.

Live video streaming

Since OctoPrint can stream video of your print as it happens, you can watch out for any faults that may require you to abort and restart. Proud of your print? Record the entire process from start to finish and upload the time-lapse video to your favourite social media platform.

Data capture

Octoprint records real-time data, such as the temperature, giving you another way to monitor your print to ensure a smooth, uninterrupted process. Moreover, the records will help with troubleshooting if there is a problem.

Print the Millenium Falcon

OK, you can print anything you like. However, this design definitely caught our eye this week.

This is a Timelapse of my biggest print project so far on my own designed/built printer. It’s 500x170x700(mm) and weights 3 Kilograms of Filament.

You can support the work of Gina and OctoPrint by visiting her Patreon account and following OctoPrint on Twitter, Facebook, or G+. And if you’ve set up a Raspberry Pi to run OctoPrint, or you’ve created some cool Pi-inspired 3D prints, make sure to share them with us on our own social media channels.

Build a Flick-controlled marble maze

via Raspberry Pi

Wiggle your fingers to guide a ball through a 3D-printed marble maze using the Pi Supply Flick board for Raspberry Pi!

Wiggle, wiggle, wiggle, wiggle, yeah

Using the Flick, previously seen in last week’s Hacker House’s gesture-controlled holographic visualiser, South Africa–based Tom Van den Bon has created a touch-free marble maze. He was motivated by, if his Twitter is any indication, his love for game-making and 3D printing.

Day 172 of #3dprint365. #3dprinted Raspberry PI Controlled Maze Thingie Part 3 #3dprint #3dprinter #thingiverse #raspberrypi #pisupply

All non-electronic parts of this build are 3D printed. The marble maze sits atop a motorised structure which moves along two axes thanks to servo motors. Tom controls the movement using gestures which are picked up by the Flick Zero, a Pi Zero–sized 3D-tracking board that can detect movement up to 15cm away.

Find the code for the maze, which takes advantage of the Flick library, on Tom’s GitHub account.

Make your own games

Our free resources are a treasure trove of fun home-brew games that you can build with your friends and family.

If you like physical games such as Tom’s gesture-controlled maze, you should definitely check out our Python quick reaction game! In it, players are pitted against each other to react as quickly as possible to a randomly lighting up LED.

You can also play solo with our Lights out game, where it’s you against four erratic lights eager to remain lit.

For games you can build on your computer with no need for any extra tech, Scratch games such as our button-smashing Olympic weightlifter and Hurdler projects are perfect — you can play them just using a keyboard and browser!

ASPIR is a full-size, Arduino-powered humanoid robot

via Arduino Blog

Building robots can be difficult, and if you want to construct something humanoid, designing the mechanics alone can be a significant task. ASPIR, which stands just over four feet tall, looks like a great place to start.

John Choi’s 3D-printed robot can move its arms, legs, and head via 33 servo motors, all controlled by an Arduino Mega, along with a servo shield.

The documentation found here is excellent; however, it comes with a warning that this is a very advanced project, taking several months to build along with $2,500 in parts. Even if you’re not willing to make that commitment, it’s worth checking out for inspiration, perhaps parts of the ASPIR could be adapted to your own design!

Students invent a low-cost electric wheelchair kit with Arduino

via Arduino Blog

While electric wheelchairs are a vital tool for those with restricted mobility, they typically cost around $2,500, an amount that’s not the most affordable. To address this problem, a group of students from Aviv High School in Israel have come up with a low-cost, 3D-printed motor conversion kit that connects to a standard push-chair without any permanent modification or damage.

The system uses a pair of motors to steer like a tank, and features a joystick and Arduino Uno for control. Another interesting feature is shown later in the video below, when it’s folded up for storage with the motor kit still attached.

You can check out the team’s website for more details this incredible project, as well as All3DP’s recent article here.
