The Gertbot board works as either a stand-alone power controller connected to a computer via a serial link and controlled from Windows or as a plug-in to the Raspberry Pi environment. It has four channels each capable of driving 30 V at 2.5 A and can drive both capacitive and inductive loads. Besides four H-bridges […]

I’ve been reading a lot about receivers, and it sounds like one important thing is filtering. It makes sense too – simple receivers can suffer from front end overload due to a strong signal.  And when on the ham bands, you never know where that strong signal may be – it could be someone driving […]

Using laser-cutting, off-the-shelf hardware and Arduino, you can make your own simple 3 axis robot. Attach a brush or pen to make a quick drawing robot, or extend Piccolo with sensors, custom toolheads, or by using multiple Piccolos together. Experiment with 2D or 3D digital fabrication at a small scale!   For more detail: PICCOLO, A […]

These days I was thinking about a better PIC programmer that can work with Microchip MPLAB IDE software so that I can write my own programs or edit someone else’s programs. I found that there are numerous versions of the famous Microchip PICkit 2 on the web. Some of them are using the original schematic […]

Introduction In my first article using the Arduino 2009 board, I described a simple temperature sensor interfaced using Visual Basic. I have developed the board and Visual Basic code to give a fairly usable indoor weather station. Overall Operation The Arduino 2009 acts as a standalone weather station. It does not display the data. It […]

This BLE smart car is completed based on our latest design Bluetooth 4.0 chiped- BLEDuino, L298 Motor shield, smart car body. The smart car production is simple, as DIY enthusiasts can complete their own smart car only in the form of building blocks, and the operation is also very simple, just controlling it via Bluetooth […]

At University, Alexander Zenger and I decided to realize a weatherstation with an Arduino Microcontroller. We wanted to measure temperature, pressure and humidity. It should be also possible to get every 5 min a value update on an external server. Our basic idea was to develop a weatherstation which is easy to use with different […]

The Bluetooth Special Interest Group (SIG) has published the specs for the next generation of Bluetooth devices. Bluetooth 4.2 has a few improvements that will be of particular interest to developers of IoT devices. The biggest change is support for an Internet Protocol Support Profile (IPSP) which enables IPv6 for Bluetooth. This means that wearable […]
