I have some years posted links to different Christmas lights project on the net. This year is no different. Here is the first one on this topic. Christmas light controller is its own percussion section article tells that Jason and his father took advantage of a week off of work over Thanksgiving to design and →
Arduino Leonardo is a pretty new microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed →
Netduino is an interesting dev board built around the .NET Micro framework with the goal of being compatible with Arduino shields. Netduino is an open source hardware platform that can run .NET Micro Framework 4.2 code. The Netduino is a dev board built around the .NET Micro framework with the goal of being compatible with →
H-bridge circuit is a very useful in electrical motor controlling. You can drive a DC motor easily at both directions with H-bridge, and if you add some PWM to driver circuit you can even control the motor speed on both directions. There are very many simple H-bridge circuit designs in Internet. Nowadays there are many →
I saw some days ago a pointer to The ultimate low-cost dev board. Or at least looks pretty close to it. The shrimp is a very, very minimal Arduino-compatible circuit meant to control all the pins on an ATMega328. The components only cost about £1.40 ($2.25 USD) when bought in volume, making it perfect for →
MaKey MaKey is an interesting gadget that allows you to easily build your own touchpad keyboard to your PC. →
OpenPLC, for industrial automation to Halloween displays article factories have programmable logic controllers to take care of their automation tasks and they are also good devices to control your Halloween effects. open-plc project is an open hardware design to build your own programmable logic controller. Included in the OpenPLC are four 24V inputs, four 24V →
The microprocessor world seems to be going in ARM direction. And so seems to be microcontrollers. Cheap ARM based 32-bit micro-controllers are taking their place and trying to replace less powerful 8- and 16-bit micro-controllers. I wrote earlier that Arduino Goes ARM. It took quite bit of time for Arduino to take that step and →
PCBs without any substrate article tells that Kimio Kosaka is taking the concept of free-formed circuits to the next level with O’Baka Project No.7. Arduino Skeleton “0′baka Project” means a stupid project. This project is to make things which is not art and which is not usable. It’s a fully functioning Arduino board, without the →
Raspberry Pi and Arduino seems to be the most interesting small single board platforms at the moment for the hobbyists. It is a bit sad to see some people who are very passionate about the Arduino community coming down quite hard on the Raspberry Pi project as the Big Bad, suggesting that we’re trying to →
