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. 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 (R1) resistor in place. (Version 3.03 and on does not … 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 →
