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 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 →
Introduction into RS-485 and CAN Bus After playing with micro controllers for a bit it gets clear that at some stage you want to control things at a distance. Doing this can very quickly get complicated and expensive. For the particular projects I wanted to control wireless was not an option as it was too … 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 →
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.
|
1 2 3 |
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 of … 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 →
Leap-motion is changing the way we interact with computers. It’s a small device that you plug into your computer that tracks the movements of your hands. Your gestures can then be turned into commands that can control applications or like in the video a robot arm. This might look like a very primitive design but if … Read More →
Having the need to do Arduino Hardware testing I decided to make a shield with a secondary ATMega328 micro-controller and ended up with this shield… Behold, an extendable multi-core Arduino!!!
The following are a few of the shield / boards that are compatible with GRBL. GRBL is G-Code interpreter that is able to run on small Atmel Micro-controllers like the controllers used on Arduino Boards. Using GRBL (software) and these micro-controllers(Hardware) makes it very easy and affordable to build your own Computer Numerated Controlled Machines(CNC) … Read More →
