Main - open-plc - OpenPLC - an open hardware alternative for automation OpenPLC is an open hardware alternative for industrial and home automation. It uses the well known ATmega chips as main processor, the same used on Arduino. This means that OpenPLC is code-compatible with all arduino sketches. The main features of the OpenPLC are: ● Protected 24V Digital Inputs (8 inputs for each module)
Open source hardware Open source hardware consists of physical artifacts of technology designed and offered by the open design movement. Both free and open source software (FOSS) as well as open source hardware is created by this open source culture movement and applies a like concept to a variety of components. The term usually means that information about the hardware is easily discerned. Hardware design (i.e. mechanical drawings, schematics, bills of material, PCB layout data, HDL source code and integrated circuit layout data), in addition to the software that drives the hardware, are all released with the FOSS approach.
20 Creative DIY Project Ideas We all have many old and unused items lying around in our homes or garages waiting to be thrown away. I don’t know if you’ve noticed, but there’s a great feeling of liberation that comes after shedding old stuff. However, before you start cleaning your home, we want to show you 20 incredibly creative Do It Yourself projects that may change your mind. You’ll learn that a lot of useless items can be transformed into wonderful creations. Digital Chromatic Guitar Tuner (2008) LCD connections. MIDI connector connections. The amplification stage, which takes the input from the guitar and feeds it to the Arduino.
Maker Faire New York Debrief - News by Emcee Grady | October 06, 2010 | 8 comments Share Use this URL to share: Share on Twitter Share on Facebook Share on Google+ As you may have known, Maker Faire New York has come and gone and SparkFun was in attendance. It was awesome! We saw some amazing projects, met some great people, and just generally had a wonderful time. One of our favorite things to do at Maker Faire is meet and talk with some of our customers. DC-DC Bipolar Power Supply for Effect Pedals « Obsoletetechnology Certain circuits require a bipolar power supply. In a portable unit like an effect pedal, that can sometimes be troublesome, since it is likely that we want to power our effects with a standard 9V or 12V wall-wart or batteries and really don’t like the idea of putting an AC mains transformer plus rectifiers and filtering into our boxes. A good way getting around this problem is by using a step-up converter, also called DC-DC converter. A DC-DC converter converts a voltage level into another voltage level by temporaryly storing the energy in a capacitor or an inductor and then releasing the energy to the output thus multiplying the output voltage. I have used the LT3467 converter in a 9V input to +-15V output configuration. The schematic is similar to the one in the LT 3467 datasheet, which you can refer to, would you require to caculate a different voltage output level.
The MacBook Air Samsung SSD is about to get twice as fast I had a chance to meet with Samsung Storage solutions at CES 2012 this week and got the low down on its new OEM SSDs that Apple tends to buy in large numbers. Samsung and Toshiba are the OEMs that provide the SSDs in MacBook Airs. Samsung’s 470 OEM SSD product is noticeably faster than the Toshiba model that Apple also puts in otherwise identical MacBook Airs. Stampendous Tutorials Welcome to my tutorials just for Stampendous!
