Loud objects & Lullatone - electronicy music and soldering
If the Maker movement had a soundtrack I think there might be couple songs from Lullatone & Loud Objects / Tristan Perich/1-Bit Music. I went to Glasslands Gallery in NY, it's a warehouse-like space in Williamsburg that had a few bleepity-bloop electronic sampled music acts in one evening. Loud Objects being a live soldering show that screams out at you with Tristan drumming out in the end, a great contrast of meat and machine (the 1-bit music CD comes with chips too)... Lullatone is from Japan and there at one point I thought I was in a 3rd grade music class taken over by Hello Kitty, Super Mario and maybe a truck of sugar.... Good times -Link.
Does Making things have a sound? Post up your fave bands in the comments (the more DIY music instrument the better)...

Arduino category on MAKE
There are so many Arduino projects lately (and we are now stocking, well trying to keep stocking) the Arudino kits in the Maker store I'm giving them their own category here on MAKE...
What's Arduino? Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments - Link.

Punch the (alarm) clock, no really...
Here's how to mod an alarm clock so that it will enter snooze mode when you smack it, Dimension Engineering writes -
In this project, we will bypass the mechanical snooze switch on top, and instead turn the alarm clock off in a much more fun way: punching it! Hopefully along the way I will be able to teach you some techniques that are useful in reverse engineering, so you can apply them to future projects.DE-ACCM application note: Hacking an alarm clock - [via] Link.This project is aimed at intermediate electronics enthusiasts, who have mastered the art of the multimeter and are comfortable with soldering a complex circuit.
This project involves working with a device that connects to mains voltages. The alarm clock I used just so happened to be designed so well that it was impossible to touch any mains voltages inside it. Other alarm clocks may not give you this comfort and will most likely have a different layout inside. Do not attempt this project unless you are 100% sure you know you can do it safely!
Zork!:
Shocking alarm clock!- Link.

DIY remote camera trigger (PDF)
Wiley has a 46+ page PDF on how to make your own DIY auto-camera trigger - [via] - Link (PDF).
From the pages of MAKE:
Kite Aerial Photography Puts Your Eye in the Sky. To take pictures from a kite, you need three things: a kite, a camera, and a special rig that attaches the camera to the kiteline and activates the shutter button on the camera. Here's how to do it.

The SunFlopper: a mini heliostat made from a floppy drive
Brian writes -
This is still pretty much a work-in-progress, but I did manage to create a successful heliostat (sun tracker) from the above TEAC model FD-235HF 3.5" floppy drive. This procedure will likely work just fine, with a bit of adaptation, on any drive new enough to have CMOS logic on its chipset. This particular drive (probably a lot of others) only needs a single 5V DC supply. It has two boards, one with the stepper and main logic, and one with the spindle. The first is the only one needed, and it draws 0.1 Watt with the motor off, and 1 Watt with the motor running, so it should be easy enough to power with a cheapo hobbyist 5V solar cell if stand-alone operation is needed, perhaps a sub-watt one if a large capacitor is supplied to build up enough juice for a motor step over time...The SunFlopper: a mini heliostat made from a floppy drive - [via] Link.

Modifying a cheap portable cellphone jammer
This is interesting, "Blastwavelabs" bought a portable cell phone jammer from a company called DealExtreme, it appears the jammer ships set to frequencies outside North America but it can be modded to work by turning the trim pots a bit (small potentiometers to tune/trim the voltage)... I'm not sure that would actually work that great without a spectrum analyzer, either way a fun read and please debate in comments about a device like this... - Link.

Intro to Breadboard Electronics - Make: Video Podcast
This weekend, learn how to put your projects on a breadboard! Start off by going to the Sparkfun site and go through their tutorial about getting power set up on your board. - Link
Then get out Make: Volume 10 (Note: I mistakenly called it volume 11 in the podcast, but it's Volume 10) and look up the article on 555 timers by Charles Platt. We're going to make a timer that you can use when playing chess to know when your partner's turn is up! I'll also put this article in the pdf that goes along with this video. - Subscribe Link

Intro to Breadboard Electronics - Make: PDFcast
Breadboarding is a great way to get started in electronics. You don't need to solder and you can put things in and take things out really easily.
The 555 is a beautiful thing. Download this pdf, read it, and make this project and learn more about this cute little 8 legged bit of silicon!

OpenFM's Open source radio transmitter
OpenFM's Open source radio transmitter -
When Adapted Consulting's co-Founder, Frederic Renet couldn't find a commercial radio that was energy efficient, easy to repair and affordable, he decided to build his own. These requirements were crucial for where he was installing radios in rural Africa. Based on that first model, Fred has designed a new radio that we call "Open FM".Main Page - OpenFM - [via] Thanks Terrie! Link.Adapted's OpenFM radio kit is a low power, affordable open source solution created for use in remote areas. The system is robust and was designed to withstand harsh weather conditions, including high temperatures, dust and humidity. It has been optimized to be energy efficient, allowing it to operate using solar power and so is particularly well suited for rural environments that lack dependable electricity.

Make a USB power/charger from a wall wart
A user on the Hacked Gadgets Forum posted this simple conversion of a common wall-wart into a USB power supply/device charger. He used the power adapter from an old Iomega drive and a few common components. I've seen several versions of these floating around. Easy to make. Nice to have around.
