We aren't as happy with LED lighting as we used to be. They are expensive, don't last long and clearly are a major source of e-waste.
A simple, quick, and very cheap circuit to turn on an LED when it gets dark. Read more about this project here.
These are the LED arrays we put together this weekend...designed on Tuesday, got parts and PCBs on Thursday, assembled them Friday night and Saturday afternoon.
Super portable Arduino-compatible thing.
- 3xAAA battery-powered
- RGB LED on PWM pins
- 38kHz IR remote receiver
- ATmega8 w/ internal oscillator running @8MHz
- old Arduino bootloader w/ fuses set to not need ext. crystal
- 15mA idle current
- fits in pocket
- causes small amounts of glee
I purchased a LED work-light at Bunnings (Same as Home Depot), for the sole purpose of possibly using it out in the field shooting portraits in low light. The light cost $27AU, and after playing for 1/2 hour with it, I love it. It's called a BatLight…..will upload pic a bit later on, after it comes off the charger :)
Sandia researchers Jerry Simmons (left to right), Jeff Tsao, and Mike Coltrin show LED devices at their lab in Sandia's Center for Integrated Nanotechnologies facility. Simmons is leading a team that has been awarded $18 million by DOE for advanced LED research and development over the next five years. (More information) Photo courtesy Sandia National Laboratories.
Made in Germany : no, it's not an Agfa, the shutterbutton is not orange but green.
Made in Singapore : no, it's not a Rollei XF, but it's a lookalike.
Made in Spain : YESSSSS, toreador prend garde à toi, toreador, toreador, ...garde à toi,...
An LED wine charm. Simple but effective. No, it doesn't blink. You could certainly put a tiny lithium battery on the back side of the stem if you wanted it to light up, but it might start to get in the way of using it as a wine glass. =(
This is part of a DIY "solder your own wine charms" project; read more about it here.

After a Plank's Constant Determination lab in AP Physics B, I decided to experiment with the infrared diodes in the lab kit and see how well they're "seen" by the camera. As it turns out, very well. The diode that appears to be lit up a violet-white color (not the bright red one to its right) is an infrared diode emitting at a vacuum wavelength of ~940nm. Of course, since it's infrared, humans are incapable of seeing it, but despite the camera's IR filter, the CCD sensor sees the infrared just fine.
For those of you interested, Wikipedia has a nice article on infrared photography.
See also this picture, which I took of the same kit but with one of the visible light LEDs.

Yesterday, I bought a non-working Canon FT QL with a Canon FL 50mm, f1.8 lens for $8. I have another FT QL, so I figured that I could use it for a parts camera. But that's not why I bought it - I wanted the lens as it's the early issue FL 50mm with the amber multi-coating (it was later changed to magenta.) Just this and the previous poppy photo, but it seems like a good lens so far.
London, England, Covent Garden, Christmas 2008, LED tubes decorate the Apple Market galleria in an interactive display activated by shoppers' movements. Detail, manipulated.
Many road authorities are switching from high pressure sodium street lights to LED.
In the living room, the difference in the light produced by these two technologies can be seen reflected in the lamp stand. The left side of the lamp stand is lit by an LED flashlight on its dimmest setting. The right side of the lamp stand is lit, through the living room window, by a high pressure sodium street lamp.
The light from outside shows an eerie amber, almost red colour. The LED produces a crisp and cheerful white.
Time to turn the light back on so that I do not trip, Van Dyke-esque over the ottoman (or tripod).

Two recent changes were made to this store. They replaced the old plastic aisle signs with the brown ones on the left and replaced the lights in the ceiling with brighter LED lights. Everything else is the orginal decor.
A sizeable Royal Navy contingent from shore establishments across south Hampshire took part in the annual Service of Remembrance in Portsmouth on Sunday (November 13).
The Band of Her Majesty’s Royal Marines Collingwood led a parade of 78 Navy personnel, marching into the city’s Guildhall Square for the service conducted by The Very Reverend David Brindley, Dean of Portsmouth Anglican Cathedral, and Father James McAuley of St John’s Roman Catholic Cathedral.
HMS Collingwood provided a 24-man guard and there were 18-strong platoons from HMS Sultan and HMS King Alfred. Ten ceremonial staff from HMS Excellent also joined the parade.
A large number of veterans received a rousing welcome as they were led into the Guildhall Square by the Portsmouth Citadel Salvation Army Band.
The service concluded with a wreath-laying ceremony at the war memorials adjacent to the Guildhall. Among the wreath-layers were Rear Admiral Richard Stokes, Assistant Chief of Naval Staff (Support), Major General Rob Magowan, Commandant General Royal Marines, and Captain Sam Shattock of the Royal Fleet Auxiliary.
