ERRF 18: New Products Make their Debut
While ostensibly the purpose of the recent East Coast RepRap Festival (ERRF) was to celebrate the 3D printing community and culture, it should come as no surprise that more than a few companies decided to use the event as an opportunity to publicly launch new products. Who can blame them? It’s not as if every day…

Putting More Tech Into More Hands: The Robin Hoods of Hackaday Prize
Many different projects started with the same thought: “That’s really expensive… I wonder if I could build my own for less.” Success is rewarded with satisfaction on top of the money saved, but true hacker heroes share their work so that others can build their own as well.

Moving Ferrofluid with PCB Coils
Moving Ferrofluid with PCB Coils!
What if ferrofluid can be moved around with a simple PCB? This is what this project is all about!
Kicad: Designing With Complex Shapes
KiCad presentation by Andrew Sowa at Teardown 2018:
Kicad: Designing With Complex Shapes
While most PCBs can be simple rectangles, sometimes the design requires more complex geometry. EDA tools don’t always make this simple, so we will go over a few KiCad tips to make it easier. In this talk you will learn how to import unique board shapes from Fusion 360, create arbitrary fill zones using images, and embed high-frequency RF filters. We will use multiple software packages to enhance KiCad’s performance beyond its obvious use.
Open Source DIY Printers are Alive and Well: What We Saw At ERRF 2018
If you follow the desktop 3D printer market, it probably won’t surprise you to hear that nearly every 3D printer on display at the inaugural East Coast RepRap Festival (ERRF) was made in China. Even Printrbot CEO Brook Drumm had to admit that this was the year his company may finally bite the bullet and begin selling a branded and customized printer built overseas.
When you can get a decent (but let’s be clear, not great) 3D printer for $200 USD, it’s no surprise that American and European manufacturers are having a hard time staying competitive. But not everyone is seduced by low-cost printers. They know they could buy a decent printer for a couple hundred bucks, but for them that’s not the point. Some hackers are just as (if not more) interested in designing and building the machines than they are churning out little plastic boats with the finished product.
Luckily for us, these are also the type of folks who document their builds and make all their collected information and design files available for others under an open source license. Such builders exemplify the true spirit of the RepRap movement, and we’re happy to report that in a sea of imported printers, there were several interesting home built open source printers.
Whether you want to build your own copy of one of these machines, or simply get inspired by some of the ideas their creators had, these machines are physical proof that just because you can order a cheap 3D printer on eBay right now doesn’t mean you have to.

How To Design Custom Shaped Boards In Fritzing
If you’re looking to get started in designing a few PCBs, you could use one of the many software packages that allow you to create a PCB quickly, easily, and with a minimum amount of fuss. You could also use Fritzing. Fritzing is terribad and you shouldn’t use it, but that doesn’t mean you still…

Story of a SparkFun AVC Rover
Multi-year adventure of building JRover from scratch, as told by its creator, Jesse Brockmann, on the SparkFun blog:
Story of a SparkFun AVC Rover
I first started working on my SparkFun AVC rover back in 2011, but I didn’t have a finished rover until 2014. I first heard about the competition on the SparkFun site and thought AVC would be a great challenge – even then I thought self-driving cars would become mainstream. I hope I can provide some useful information for those of you working on or considering making a rover.
My latest rover uses the following components:
- Traxxas Slash 4×4 Platinum LCG Truck
- Anaconda street tires
- Traxxas RPM sensor
- RC4WD 35-turn brushed motor
- Castle ESC
- 3S 5400mah LiPo
- Teensy 3.5
- 2GB+ micro SD card
- BNO-055 IMU
- Headers
- Various jumper wires
- Tactile Buttons
- Custom JRover Baseboard and Button Board
- Digole 2” LCD display
- Airplane RC transmitter and receiver with PPM output
- USB battery bank
Video Quick-Bit: The Things That Move Robots
Magenta Strongheart returns for a look at some of the coolest robotic entries from this year’s Hackaday Prize. Each of these answered the challenge for modular designs that will help supercharge new robot projects. We think that cheap and abundant motor designs are poised to revolutionize robotics and several of the entries thought along those…
