I just designed an open source digital bench power supply using +Atmel 's Atmega8 and the results are nice http://www.pocketmagic.net/digital-bench-power-supply/ . Adjustable voltage and current, shortcircuit protection, temperature protection, alarm sounds, simple interface and a generous LCD. 
Circuit diagram and construction details for a DIY digital variable regulated power supply, for your work bench. A new design made from scratch.

+Radu Motisan​ ok. Prima oara tre sa termin un proiect care mi-a scos peri albi si după aia o fac. Tot diferit fata de tine o sa fac softul in arduino. BTW ai încercat sa comanzi ceva in pwm de pe sursa ta? Nu vâjâie?

+Atmel, global leader in microcontroller solutions, featured #uRADMonitor in their blog post http://blog.atmel.com/2015/03/30/building-a-portable-environmental-monitor-to-combat-pollution/ #IoT   #nuclear  
This Hackaday Prize entry will measure and track air quality using a global infrastructure.  It’s no secret that air pollution, particularly matter that goes unseen by the human eye, ranks high amo...

It's a bit weird to imagine everything with an IP address. I'm not entirely sure how I feel about this idea.

The open source uRADMonitor-KIT1 is intended for those interested in building their own radiation devices to contribute to the uRADMonitor network. http://www.uradmonitor.com/uradmonitor-kit1-an-open-source-diy-dosimeter/ #uradmonitor

6 Radiation Dosimeters have been put to a test. Results are surprising: http://www.pocketmagic.net/comparison-of-dosimeters/ #uradmonitor #nuclear 
An article presenting a comparison of dosimeters, showing how different the measurements can be even when using the same radiation source.

The second #uRADMonitor unit in Turkey went online http://www.uradmonitor.com/?open=12000047  #IoT #nuclear #safety 
View the global radiation map, the radiation levels and detailed readings if you click any of the nodes on the map.

Hey guys, here's my new project for HaD Prize 2015 addressing pollution and environmental air quality monitoring . You can vote by pressing the "Give a Skull" button!
The portable environmental monitor addresses pollution, the kind that we are unable to see but directly affects our health and causes life threatening diseases such as cancer. Airborne toxic chemicals, radioactive dust and radioactive radon are correlated with cases of pulmonary cancer. Since our biological senses can do little to warn us of such possible dangers, we plan to design the Portable environmental monitor as a first line detection and...

@hackaday prize 2015 starts tomorrow. Wondering what's the best idea I should participate with, out of the many appealing possibilities. Ideally, it should be the type of technology that people can benefit from, making a better future for us all.
This is about doing, not about about waiting for something to happen. The Hackaday Prize will send one person into space for building the next evolution of hardware.
