NextThingCo Introduces C.H.I.P. Pro, GR8 System On Module

Posted on by

NextThingCo, makers of the very popular C.H.I.P. single board Linux computer, have released the latest iteration of their hardware. It’s the C.H.I.P. Pro, an SBC designed to be the embedded brains of your next great project, product, or Internet of Things thing.

The C.H.I.P. Pro features an Allwinner R8 ARMv7 Cortex-A8 running at 1 GHz, a MALI-400 GPU, and either 256 MB or 512 MB of NAND Flash. The Pro also features 802.11 b/g/n WiFi, Bluetooth 4.2, and is fully certified by the FCC. This board will be available in December at supposedly any quantity for $16.

The design of …read more

Creating A PCB In Everything: Friends Don’t Let Friends Use Fritzing

Posted on by

This week, we’re continuing our Creating A PCB In Everything series, where we go through the steps to create a simple, barebones PCB in different EDA suites. We’re done with Eagle, and now it’s time to move onto Fritzing.

Fritzing came out of the Interaction Design Lab at the University of Applied Sciences of Potsdam in 2007 as a project initiated by Professor Reto Wettach, André Knörig and Zach Eveland. It is frequently compared to Processing, Wiring, or Arduino in that it provides an easy way for artists, creatives, or ‘makers’ to dip their toes into the waters of PCB …read more

Hackaday Prize Entry: Augmented Reality Historical Reenactments

Posted on by

Go to a pier, boardwalk, the tip of Manhattan, or a battlefield, and you’ll see beautifully crafted coin operated binoculars. Drop a coin in, and you’ll see the Statue of Liberty, a container ship rolling coal, or a beautiful pasture that was once the site of terrific horrors. For just a quarter, these binoculars allow you to take in the sights, but simply by virtue of the location of where these machines are placed, you’re standing in the midsts of history. There’s so much more there. If only there was a way to experience that.

This is why [Ben …read more

Porting NES to the ESP32

Posted on by

There’s an elephant in the room when it comes to the Raspberry Pi Zero. The Pi Zero is an immensely popular single board computer, but out of stock issues for the first year may be due to one simple fact: you can run a Nintendo emulator on it. Instead of cool projects like clusters, CNC controllers, and Linux-based throwies, all the potential for the Pi Zero was initially wasted on rescuing the princess.

Espressif has a new chip coming out, the ESP32, and it’s a miraculous Internet of Things thing. It’s cheap, exceptionally powerful, and although we expect the stock …read more

These 20 Projects Won $1000 For Assistive Technologies

Posted on by

For the last seven months, Hackaday has been hosting the greatest hardware competition on Earth. The Hackaday Prize is a challenge to Build Something That Matters, asking hardware creators around the world to focus their skills to change the world.

The results have been spectacular. In five rounds of design challenges, we’ve seen more than 1000 entries and so far eighty of them have won $1000 and a chance to win the Grand Prize: $150,000 and a residency at the Supplyframe DesignLab in Pasadena.

Last week, we wrapped up the last challenge for the Hackaday Prize: Assistive Technologies. We’re …read more

Hackaday Links: October 9, 2016

Atari is back! That’s what some dude says. There are no real details in that post, other than ‘Atari is Back!’

The ESP32 is coming, and it’s going to be awesome. Espressif has just released an Arduino core for the ESP32 WiFi chip. The digitalRead, digitalWrite, SPI, Serial, Wire, and WiFi “should” work. If you’re looking for ESP32 hardware, they’re infrequently available and frequently out of stock. Thankfully, stock levels won’t be the Raspberry Pi Zero all over again until someone figures out how to run an NES emulator on the ESP32.

Tiny, cheap ARM boards would make for great …read more

Certification For Open Source Hardware Anounced

Posted on by

Today at the Open Hardware Summit in Portland, Alicia Gibb and Michael Weinberg of the Open Source Hardware Association (OSHWA) launched the Open Source Hardware Certification program. It’s live, and you can certify your own hardware as Open Hardware right now.

What Is Open Source Hardware?

Open Source Hardware can’t be defined without first discussing open source software. At its very core, open source software is just a copyright hack, enabled by a worldwide universal computer network. The rise of open source software is tied to the increasing ease of distributing said software, either through BBSes, Usenet, and the web. …read more

Tiny Smoothies At Maker Faire

Posted on by

For almost the last decade, desktop 3D printing has, at its heart, been centered around 8-bit microcontrollers. The ATmegas and other Atmel chips are good enough to move a few steppers and squirt some plastic. With faster processors, you get smoother acceleration, leading to better prints. Modern ARM devices have a lot of peripherals, allowing for onboard WiFi and Ethernet connectivity. The future is 32-bit print controllers.

Right now there are a few 32-bit controllers, from the very weird, out-of-nowhere controller for the Monoprice Mini 3D printer to the more traditional SmoothieBoard. Only one of these boards has the open …read more

A Reproduction Vintage Sound Card

Posted on by

Before the AdLib sound card, sound on PCs was in a terrible shape. Since the dawn of IBM, all PCs included a speaker, but this PC speaker was only capable of sounding one note at a time. Chords on the PC speaker produced a weird ‘bubbling’ effect. Just a few years later, 8-bit sound could be created with the Covox Speech Thing, effectively a resistor ladder, with the parallel port on one side, and an 1/8″ plug on the other. These solutions for PC sound sucked.

It wasn’t until the first AdLib cards that superior sound showed up on the …read more

DIY Nozzle Socks For Your 3D Printer

Posted on by

If you have a 3D printer, your nozzle and heater block are invariably covered in a weird goo consisting of decomposed and burnt plastic. There’s only one way around this – a nozzle sock, or a silicone boot that wraps around the heater block and stops all that goo from accumulating.

Right now, E3D sells silicone nozzle socks for their normal-sized heater blocks, with a release for their maxi-sized Volcano blocks coming shortly. [Ubermeisters] couldn’t wait, so he designed a 3D printed mold to cast as many Volcano nozzle socks as he could ever need.

The mold itself is taken …read more
