Introduction From project to project the number of hex files on our PC was increasing. Many people send us their virgin ATMegas to get them flashed. And last not least distributing PCB’s and pre-flahed chips via agile-hardware forced us to burn many, many AVRs. In principle this is a work an ape should do but […]

In this Instructable, we will be building a compass using the TinyShield Compass as well as the Circle Edge Led shield. Step 1: Materials After getting your boards and battery, the Arduino IDE will be the first thing to download if you have not done so already. When the IDE has been loaded go to
GPS Clock Assembly, Part III January 10, 2015 Filed in: GPS | Arduino | Electronics | Clocks | Laser Cutting Pinoco was hit with the holiday rush, so it took a few extra weeks to get my new batch of laser cut acrylic. I nailed it this time. Right away I could tell the engraving

Swiss scientists have created the first semiconductor laser consisting solely of elements of main group IV (the carbon group) on the periodic table. Simply, this means that the new device is directly compatible with other elements in that group – such as silicon, carbon, and lead – and so can be directly incorporated in a

The MX100T from Aim-TTi (Aim Thurlby Thandar) is a 315W precision laboratory power supply’s three outputs can each provide 0 to 35 V at 0 to 3 A. Range switching extends the capabilities so that outputs can be set to 16 V/6 A or 70 V/1.5 A for maximum versatility; where higher power is needed

This library is an update of the software PWM driver you can find here: http://davidegironi.blogspot.it/2013/03/controlling-dc-motor-speed-and_6.html For DC motor information please look at the above link. This update implements also progressive start / stop features using hardware timer. The PWM frequency have to be selected in the way that the switch frequency is much higher than the dynamics

In embedded systems, oftentimes it is needed to generate analog outputs from a microcontroller. Examples of such include, generating audio tones, voice, music, smooth continuous waveforms, function generators, voltage reference generators, etc. Traditionally in such cases the most common techniques applied are based on Pulse Width Modulation (PWM), resistor networks and external Digital-to-Analog Converter (DAC)
The batteries inside our smartphones and laptops are fighting a losing battle when it comes to keeping these devices juiced up, but researchers from ETH Zurich have discovered a new type of glass material that could make a major difference: vanadate-borate glass. The glass can be used as an electrode material in lithium-ion batteries to

Encapsulated in a tiny 9.0×6.5×1.83-mm QFN package, the ISL8203M step-down DC/DC power module from Intersil furnishes an adjustable output voltage between 0.8 V to 5 V to allow designers to use one device to build a single 6-A or dual 3-A output power supply. The ISL8203M simplifies power-supply design for FPGAs, ASICs, microprocessors, DSPs, and

Here’s the finished DAC! it was a very fun project and very fulfilling to make something that I actually use everyday. Overall the audio specs aren’t anything amazing, but it definitely is an improvement on the built in audio of my computer. Another Shot of the Finished DAC Pretty Blue Lights!!! There are two LED’s
