An open source USB programmer for PIC micros, I2C EEPROMs, some ATMEL micros, generic I2C/SPI devices and (soon) other devices.
Open Programmer PIC and Atmel
- Completely free and Open Source (including firmware)
- Programs PIC10-12-16-18, 24xxxx I2C EEPROMs, some ATMEL micros, communicates with generic I2C & SPI devices (see supported devices)
- USB interface, HID class (same as keyboards, mice, etc.)
- Self powered
- Doesn’t need drivers
- Built from easy to find components (estimated cost ~10€)
- Hardware generated timings for maximum speed and reliability (writes a 18F2550 in 15s, 8s under Linux)
- Doesn’t saturate your CPU and doesn’t suffer when other programs are running
- Open source control programs for Linux and Windows

First have a look at this How to Build a Robot a BeetleBot. This sparked the long lost memory of a book i read around 35 years back. My age was in single digits. This was when i had neither an idea of electronics or could afford any parts.
I had built many physics projects like weighing scale, gramophone, telegraph system, crystal radio. I will try to explain these later. Calling bells, gears and magnets from the flea markets my source of electricity & magnetism.
I read a hobby book from UK for children. It was a Beetle Car Bot, with four wheels and 4 light sensors. It could be LDR or photo-transistors, i do not remember. The light sensors were at the four corners of the car. The maneuvering was by variation in the speed of each wheel. It was based on germanium transistors mostly.
Four large lamps like 40W, had to be mounted on the ceiling, at the four corners of the room. By turning on and off these lights, this bot could go anywhere in the room. The whole book with pictures was dedicated to one bot and how-to build one.
Now that we have PIC and AVR; we can use Dimmable LED Lightning arrays to guide the bot. The challenge is in the mechanics of the bot, we have to forget that we have wireless for some time. Try this out.
BitScopes are USB or Ethernet connected PC Based Mixed Signal Oscilloscopes. This means they capture and display one, two or four analog signals and eight logic or timing signals, simultaneously. Any BitScope can be used as a Digital Storage Oscilloscope, Logic State Analyzer, Spectrum Analyzer or Data Recorder.

BS325 is a classic 2+8 channel BitScope which combines deep capture high performance mixed signal data acquisition and full network connectivity in one compact unit.
BitScope 325 – PC Oscilloscope
BS325 connects via ethernet and is electrically isolated from the host. USB adapters are also available.
BS325 is user programmable, software extendable and can be integrated with third party software.
To make this easy the BitScope Library is available for BS325. The library can be used to create custom applications or to integrate one or more BS325 units into specialised testing and data acquisition systems.
The library is included as standard with BS325 and is compatible for Windows, Linux and Macintosh platforms.
If you want to build electronic circuits, you need to connect the components of your circuit somehow. If you expect to make your circuit work more than just a few times, you need a solid way of connecting them. You need to create a printed circuit board (PCB).
“I started playing with electronics as a hobby when I was 14. Since then I have finished a Master’s degree and founded two electronic design companies.”

The radar sensor uses a Ultra-Wideband (UWB) chip from Novelda. It sends out electromagnetic pulses and analyzes the pulses that are reflected back. In the video above, a part of the electromagnetic pulse will be reflected back when it hits the wall and a part of it penetrates the wall and is reflected from the cabinet behind the wall.
