230mA output current. Very far from the rated 3A.
I think I need to get or build some sort of dummy load to test this thing further. Big fat transistor, big fat heatsink, current sense resistor + opamp as constant current source. Mabe some 4mm banana binding posts to use my DMM as current meter.
A new generation of cheap lightweight plastic electronic technology that does not require silicon, but which is optically transparent and can be coated onto everyday objects would transform our world.
"Working collaboratively with industry is not only satisfying in that I see aspects of my work translate into real engineered products, but it provides inspiration for new avenues of research too. Roadmapping then allows me to critically assess how I should be developing my research portfolio and engaging with industry to maximise the likelihood of productive collaboration."

Imagine electronically updated food labels, computers embedded in our armchairs, even contact lenses linking us directly to the Internet to bring us into the age of plastic electronics. In this video podcast Dr Andrew Flewitt and Dr Robert Phaal both from the Department of Engineering and Scott White serial entrepreneur and CEO of Pragmatic Printing talk about the creative partnership forged between different parts of the Department of Engineering and outside companies that enable the technology and research in this area to be exploited successfully.

no problem with SnPbCu solder. the lead-free stuff wets badly, doesn't stay liquid long enough and gets solid in strange ways.

Another implementation of the classic two transistor Joule Thief circuit, made entirely with surface mount components.
How to use a USBTinyISP with a breadboard. The secret is that the 10-pin header has all the pins you care about along one row.
Got a bigger breadboard :) Refactored my wires onto it. It's still hooked up to the Arduino and running Hello World.
Next step is to move it to the Raspberry Pi and get it working with some Python code I wrote.
Consumer electronics wholesale apple, iPhone distributors companies USA
Whenever it comes to sell or buy anything online the Apple devices, then every iPhone distributing companies in the USA try to be authenticated. Sometimes, it becomes hard to trust who you will trust and to whom you can buy or sell your apple devices. GlobalGeeks is one of the best iPhone
distributing company which gives you the best wholesale rates of the apple devices.

First hack for the new PS3Eye goes to Rui Pereira twitter.com/rux_twitts_here
The via is located on the front of the PCB, directly above the R19 resistor.
Council Member Brewer participated in the April 23, 2006 Manhattan Electronics Recycling Event.
Sponsors: The NYC Department of Sanitiation is sponsoring this electronics recycling event through the assistance of the Lower East Side Ecology Center and the support of Con Edison. Special thanks to our partner, the NYC Department of Park & Recreation.
555 timer set in astable mode, triggering brief pulse to turn on LED connected via separate power source using an opto-coupler. Green LED lit inbetween pulses. Red LED lit with pulse. Yellow LED on separate circuit and lit via optocoupler when pulse occurs.
This time was much more successful. I applied the solder paste with the tip of a sewing needle. Smearing it across the pads until I thought I had enough.
Result: No bridged pins!
First bit of soldering for electronics that will fit inside the nightlight/thermometer. Slide switch will be used to control whether operates as night light (constant light) or thermometer (changes color based on temperature)

FunkKit - designed By Ayal Avisar
Design Inspiration: I tried to think of different kind of transformations shoes might have in their "lifetime", this is one of them.
About the Designer
Double A, AKA Ayal Avisar, is 25 y old from Jerusalem. A Student from Bezalel Academy in Israel. Loves Foo Fighters and rock music.
This was the kitchen table on 3/19/2006. These are parts I desoldered and removed from TVs, computer power supplies, radios, camera flashes, and lots of other things which were parts of something else. I had to take this picture before I cleaned the table.
