HOW TO - Make a cheap $5 camera handlebar mount for a motorcycle
Curtis writes - "I made a very inexpensive mount to stick my small digital camera onto my motorcycle handlebars. Using video mode and a large SD card I can record video while running the bike through canyons, and since it is behind the windscreen even the audio doesn't sound that bad." - Link.

HOW TO - Make a RGB mood lamp
Tobe shows you how to make a really neat RGB lamp - "On this page i will explain how i created my own colour changing lamp with red, green and blue leds that fades between all colours of the rainbow. It really comes out well at night when other light are dimmed. In daylight conditions the colors aren't noticed well. Although it's low budget i must say the result is nice. Here are some photo's of my lamp in action. Click on any foto to see it in a bigger size." [via] - Link.

HOW TO - Make a simple AM radio
Here's how to make a fantastic (and simple) AM radio, Grendel - "I just finished making quite possibly the world's most simple radio. I had read a few HOWTOs for constructing a crystal radio. Some links offered the basic formulas for figuring the specs needed for the coil if you wanted to tune various frequencies. I purchased 3 spools of "Enamel-Coated Magnet Wire" from Radio Shack for ~$5, and picked up a crystal ear piece while at EPO in Houston." [via] - Link.

DIY Retro iPod
Brunurb writes - "A classic radio used as an iPod Portable Audio System. Hacked this classic radio so that it worked as an iPod boombox. It works with 4 batteries to power the amplifier giving high volume level, ideal for outdoor use. It can also work without batteries with a volume suitable for indoor listening. Go to photos on the right to view the building instructions." - Link.

HOW TO - Raising cockroaches (intentionally)
Leevonk shows you how to make a nice habitat for raising cockroaches - "...simple instructions on how to make a happy habitat for cockroaches to thrive. Taking a look around my kitchen, it seems that a lack of work is involved in this task. This is pretty much true. But in case anyone wants to be sure of how to make a good habitat, this is how." - Link.
Why would you want to do this? See the previous project of course...
Cockroach Control System (via psychological manipulation) - Link.
Allows a microcomputer (e.g. basic stamp) to autonomously control a cockroach's direction of movement. You could also make a remote control system. The basic stamp sends TTL signals to a uLN2803 chip which amplifies the current enough to contract a nitinol (shape memory alloy) strand. The contracting nitinol strand flips open one of two flaps which hang on either side of the cockroach's antennae. This creates an illusion for the cockroach of -
- "hallway",
- "wall left, open right", and
- "wall right, open left"

HOW TO - Make a "Time Fountain"
Nathan made an incredible "Time Fountain" fluorescent drops illuminated by LEDs, he writes - "I suppose it might be called a "Backwards in Time Fountain" or a "Time Manipulation Fountain" but I figured those titles would be a bit long. Using an old battery-powered small fountain as a base, drops are pumped through a brass tube, falling out of the end at a very regular interval. A microcontroller coordinates the speed of the pump and the strobe rate of the LEDs." - Link.

HOW TO - Make coin wrap rolls
Dimitrios writes - "Having to sort coins each month for my side business, I wanted a quick solution to the trouble of doing this with torn paper, and handwriting the denominations on the rolls. I searched the internet thinking that surely this must be downloadable somewhere, only to find it wasn't. Sure, you can buy these rolls ready made at an office store, but that's like a box of 5,000 boring rolls. Instead I designed my own, and made it available to the public for free..." - Link.

Science project - Electric Motor
MAKE Flickr photo pool member Oskay's son Christian built this electric motor his third grade science project, he writes - "What is a good science project and turns really fast? An electric motor! I built an electric motor for my school science project in third grade. It was fun to build and got a lot of attention at the school's science fair. I was looking in a book for a science project idea when I saw instructions for building an electric motor. My parents approved the idea, so Windell and I went looking for parts. " - Link.

HOW TO - Make a garage door monitor
HomeToys has a pretty intense garage door monitoring project (code included) - "One critical monitoring element for any home automation system is the garage door. There are many ways to do this including using your traditional magnetic contacts which will change state when the garage door is open or closed. This method satisfies the minimal requirement of knowing the open/close status of the garage door. But what happens if more detail about the garage door is needed? For instance what can you do if you would like to know the exact position of the door (say if it got stuck during its open/close travel)? What if you wanted to know this garage door position to within a few inches?" [via] - Link.

USB circuit design
Electronics-project-design.com has a background of what USB is and does as well as a reference project to check out - "The following USB2.0 reference project from Freescale Semiconductor describes in detailed the design of a USB2.0 Card Reader. It support cards such as Compactflash, Memory Stick, Memory Stick Duo, Magic Gate, Secure Digital, MultimediaCard and SmartMedia. The schematic and source code of the reference projects are provided. This project is a good reference for students who need to do an electronics project in their final year of studies." - Link & Universal serial bus card reader.

HOW TO - Make a DIY camera strap
Homemade, professional looking camera strap @ Mattyfu - "Alrighty so I just got my new camera (kodak p850) and it is wicked rad and I'm having lots of fun figuring out all the buttons and whatnot but now that I have a real camera I need a real camera strap, the one that came with it is fairly comfortable but I never wear straps around my neck so I've been checking ebay and google for possible alternatives. Fortunately a product already exists that is exactly what I'm looking for, actually many many different variations of what I'm looking for exist and they all have one thing in common, they're all ridiculously overpriced for the amount of material that your getting. I'm cheap crafty I think I can make my own for less and have just as good of a product. And so it begins." [via] - Link.

RF-Condenser microphone circuit
Here's how to make a RF-Condenser microphone circuit that's similar to a Sennheiser MKH series mic, Uwe writes - "This RF-circuit is operating at 7.68 MHz and 48 V phantom power supplied. It is tested with a large diaphragm cardioid capsule from Ralf Falk, who himself is designing a LF tube microphone and with a small diaphragm capsule from a Sennheiser MKH415... Lots of experiments, gathered experiences and improvements during the development - with quite satisfactory results, to my point of view." - Link.

"Hacking" Nokia cell phone LCDs
Jakob has a handy guide on (re)using the Nokia cell phone LCD screens for projects, he writes - "Many old Nokia cellular phones have graphical LCDs based on the PCD8544 controller. These are perfect for various electronic projects with microcontrollers. The interface is a two-wire serial type (clock and data), and some additional signals. The LCD supply is a single 3.3 V with very low supply current." - Link.
