We loved Arduino Nano’s but always wanted a bit more performance and memory. So we decided to create a Arduino Nano compatible board but with an upgrade micro-controller that is similar to an Arduino Zero. They are now ready and shipping from our online store : Protoneer Online Store http://wiki.protoneer.co.nz/NANO-ARM Nano-ARM forum page
Do it yourself CNC projects are popping up everywhere and we decided that we wanted to contribute to the growth. Here are a few of our design goals: Modular Design – We wanted to do more than just keep cost down. We wanted things to be reusable and up-gradable. (Arduino , Individual Stepper Motor Drivers and … Read More →
I have lately been flashing a bunch of Arduino micro-controllers with GRBL and I had a small issue where an older version of GRBL’s settings were stuck in the Arduino’s EEPROM. To get around this I used a quick script from the Arduino website to clear it. I thought it would be useful for people … Read More →
I am currently working on a neat project (Raspberry Pi CNC Board) where I have to program a bunch of Arduinos for each of the boards I am making. At first I did it with the Arduino IDE one board at a time but that was very tedious and required me to sometime change the … Read More →
A few months ago while designing the Arduino CNC Shield I bumped into a guy that was also going through the process of building a CNC machine. Between us we had some good brain storms and ended up with the current version of the CNC Shield. He has been keeping himself busy with a few interesting … Read More →
UFactory.cc has designed a promising DIY robot arm that is able to lift over 300gm using standard hobby Servo’s. The Robot Arm has 4 degrees of freedom at the moment but I can see it being modified to be even more flexible. The Design is based on one of the fastest palletising robot … Read More →
This is a quick guide to help with assembling the Arduino CNC Shield V3.XX. We also have a discussion forum for this board : http://forum.protoneer.co.nz/viewforum.php?f=6 Contents: Assembly Steps First Run Jumper Settings. 4th Axis Configuration End Stop Configuration Configuring Micro Stepping for Each Axis First step is to solder the Power Wire( or Fuse) and 10K … Read More →
Luca Dentella posted an example on his blog about creating a full-working dashboard for Arduino (charts and gauges) in Javascript, running entirely in a web browser without the need for a web-server. In this implementation, Luca uses the Arduino connected to an AM2302 sensor (DHT22) to get temperature and humidity values, which are then displayed on the dashboard. … Read More →
If you have ever tried to use sprintf() on an Arduino to convert from a float to a string, you will notice it doesn’t work. sprintf(buf,”%f”, floatvar); The above function will most likely return a “?” to your char buffer. If you google around, you’ll see various functions that people have written to overcome this, but all … Read More →
Cellular made easy – Add GSM/3G support to your Arduino/Raspberry Pi/BeagleBone projects Chris Higgins at SparqEE has come up with a simple development board[CELLv1.0] that can give your projects cellular capabilities. So what can you actually do with it? Well,I can think of lots of things: Add an off-grid internet connection to your home automation system. … Read More →
