What are we going to do is program an ATMega328P without an external crystal by using USBASP programmer and the Arduino IDE. Why would we want this? It uses less components and gets up closer to knowing how to program with something like WINAVR and because programming is fun an addicting. Not everything runs on […]

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 […]

Ok first of all this was a final project for my microprocessor course in my University, and its intended to clarify and guide to someone has a similar project or just want to do it and learn , since when i was doing this project it wasn’t so easy to find the information and examples […]

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) […]

(Phys.org)—Two large international teams of researchers have conducted two separate analysis of the nature of plants and each has found something new. Both teams have had their work published in the latest issue of the journal Nature—the first looks at trait commonalities among plant forms that allow for surviving natural selection

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 […]

**DISCLAIMER** I do not and will not take responsibility for anyone who gets in trouble for this, by either imitating emergency personnel, or using without a permit/lisence. Updates! -I have shortened the code -Changed 16 LED’s to 8 -Changed/added more flash patterns -Renamed variables As promised, this is the ATMega 2650 version of the police […]
