Lightning activated camera shutter trigger

Ldetrev1
Lightng1
FC writes -

This circuit is used to trigger a camera's electronic shutter circuit when a flash of lightning is present. This circuit would also work for photographing fireworks displays or other events involving flashes of light. In a nutshell, the photo darlington converts light pulses into electrical pulses, the first LM324 section amplifies the electrical pulses, the second LM324 section is a high pass filter that only passes quick changes (lightning). The third LM324 stage is a comparator that allows only large pulses to pass through, and the 4047 one-shot stretches out the length of the pulses so that they are long enough to drive the relay and trigger the camera.

Interfacing an AVR controller to a GPS mobile phone

2687281 C4B1D8D0E3
Alex writes -

My goal is to build a kind of a mobile tracker. There are many different use cases you can think of but one of the obvious is a device, that is able to report where it is. This device can be put in your car and it could trigger an alarm, if the car got stolen. Actually it could tell you where it is.
There are already mobile tracking devices out there, but they seemed to be too expensive and too closed for my needs. Another option is one of these new Nokia N95 which have built-in GPS. They are really nice, but about 600€, which is not a bargain. So I decided to do my own.

Ben writes -

Stealth lamp was designed for a student project for a London company. They took no notice, but I am happy to give my designs to the wider community under CC. If there is lots of interst I will upload all my models.

The stealth lamp is made from 0.9mm white polypropylene, and can be laser cut in under 30 secounds. The constuction is supported by a light socket that folds the shade into place.

HOW TO - Make a camera cozy

842765623 5Da9A40C33
Evil Mad Scientist Laboratories show you how to make a neat camera cozy! -

This camera cozy protects your LCD and keeps your lens cap on when you toss your camera in your bag or are just carrying it around. It also provides storage for a spare set of batteries as well as a location for the dead ones you're taking out.

It was designed for the Canon S2IS and S3IS, but the pattern can be adapted for other similarly shaped cameras.

Disposable camera mods

Macro Lens
Greg writes -

I have been looking at mods and hacks for a while now, and I always save them when I see something cool. I have done several DIY projects using a disposable camera, and so they have always peaked my interest. I decided to take all of the mods that I have seen over the last few years and make a top ten list of what I think are the coolest mods for a disposable camera. These hacks are in no particular order.

uPNP audio streaming to the Neuros OSD

Joe writes -

It's projects like this that really illustrate the promise of the OSD: combine open source code, open standards and google summer of code and suddenly you get interoperability with a host of pc media players. It also serves to remind that a great application of the OSD is streaming audio from the PC to your stereo (or net radio shortly). The efforts to port XMMS2 to the OSD are ongoing, and now Progeny's recent Google Summer of Code project to bring uPnP to the OSD. If you're not familiar with uPNP, the demo video here should bring you up to speed (at least on one possible application). Basically what we've implemented so far is the ability to share not only your audio collection but all the media management from your PC media player to the OSD. This means if you've spent time rating your songs, creating playlist, etc then you can have all that information located in one central place and access it from your OSD.

Simple homemade tilt activated switch

imagitronics writes -

I started working on my next project tonight and realized that I needed four tilt activated switches. I wasn't exactly sure what would make a good tilt switch. The majority of online videos and tutorials for tilt switches were either undocumented, mercury based, or actually accelerometers. Luckily I found these small steel hooyahs. I have no idea what they were actually designed for, but they make pretty handy little switches.

Doublet amplifier

Sam writes -

A few weeks back I wrote up a blog about the Doublet Headphone Amplifier which lets two people listen to the same audio source with independent volume controls. I got so many emails from folks who were interested in building one that I decided to make another run of the printed circuit boards - and they've arrived!

If you want one of the PCBs, email me with your mailing address and I'll drop one in the mail to you at no charge. You'll have to supply the parts and the Altoids tin.

Music key display

Make 824
The latest Gadget Freak shows you how to make a music key display -

There was dissonance in the church when the pianist and other musicians had to hunt for the key their Music Leader was playing in. Dick's gadget took the guesswork out of the guitar, the meandering out of the mandolin and the pondering out of the piano. The Music Leader communicates the key to the others by setting the display on his Sending Unit via pushbutton or the foot switch, and the Remote Units replicate that display for everyone else. Now, they're all in one A chord (or F, or C, or...).
