Make an "Easy Button" musical interface
Jro writes - "This project modifies a $5 Staple's Easy Button and an inexpensive USB keyboard so that they can be used as an input device for live musical performances (or anything else that requires a button or footswitch). It alllows cheap buttons to be created that each send a keyboard character as input to a program. In addition, the proceeds of easy button sales goes to the Boys and Girls Club of America." - Link.

HOW TO - Make a Nikon D200 GPS mount and cable (GPS camera)
Kevin writes - "I have been searching for a good way to connect a Nikon D200 to a GPS in order to geocode photos. I have not found a solution that I thought was near a reasonable price. I have therefore made my own. I made a project page for it and posted it for all to see and replicate..." [via] - Link.

PIC Based Oscilloscope with LCD
Steve writes - "Here's my latest oscilloscope project, this time utilizing a graphical LCD...The oscilloscope measures the average voltage, the maximum voltage, the minimum voltage, the peak-to-peak voltage, and the zero-crossing frequency for a DC signal over 100 samples. The oscilloscope has a built in edge trigger function that can be set to capture on rise or fall (or disabled altogether). The time scale for the display is variable and can be easily redefined. Likewise, the voltage range can be change to 0-5V, 0-2.5V, and 0-1.25V. The main limitations of this oscilloscope include relatively slow acquisition time and sampling rate (~60kHz) and the fact that the inputs are limited by the constraints of the internal ADC." - Link.

Making quick prototyping modules
Here's an older-ish how-to on making quick prototyping modules, Jeff writes - "For years I have had a need to quickly create electronic circuitry for experimentation. Like most other people I have gone through all the stages. Wire-wrap, soldering point-to-point, pluggable ProtoBoards. I have tried various methods for making my PC boards. Iron-on transfer, plotting directly on PC boards, tape on boards and various forms of photo etch. Even when I had good results I still had a single purpose board. Sometimes you can modify the board for another purpose, but there had to be a better way. I had been contemplating creating modules with the old methods. Probably point-to-point wiring on perf board. But after seeing that people were having good luck with PC boards from places like www.apcircuits.com and www.olimex.com I decided to go directly to PC boards..." - Link (schematics included).

HOW TO - Make a digital thermometer
Simon @ SciToys show you how to make a DIY digital thermometer a multimeter, LM34 / LM35 ICs, 180k ohm resistor, and a 9V battery - "With the easy availability of inexpensive digital multimeters, and integrated circuit temperature sensors, it is now very easy to build a sensitive and accurate digital thermometer that can be used for many experiments around the house or in the amateur laboratory.
There are two tenperature sensors that make this particulary easy -- the LM34 and the LM35. These are callibrated in Fahrenheit and Celsius respectively, and when read by the meter, they produce ten millivolts per degree in their respective scales, so the meter can be directly read in temperatures, down to a tenth of a degree.

Parallax Propeller (review)
EiED online's Bill Wong reviews the propellor multicore processor from Parallax (best known for their BASIC stamp) - "Parallax took a major turn from its bread and butter Basic Stamps and SX processors with its new Propeller architecture. The Propeller packs eight 32-bit processors, called cogs, into a single package... Packing eight identical processors in the same package with shared memory may seem like a straight forward architecture but the Propeller is a bit more complicated and novel. For example, all eight cogs have access to all of the same 32 IO pins at the same time. This can make debugging a bit difficult if two processors accidentally use the same pin at the same time in a different fashion. This simply means designers need to have a good understanding of the application and its implementation." [via] - Link.

This is not your grandfather's HAM radio...
Here's a special MAKEZine.com article "This is not your grandfather's HAM radio" - by Thomas Arey N2EI.
Many folks who read Make probably have an image of their grandfather, father, or kindly older neighbor heading down into their basement to talk to people around the world by way of amateur radio. This classic image of voice (and Morse code) communication is still played out every day in thousands of locations. HF radio communication has long been the mainstay of amateur radio.
In the world of modern electronics communication and experimentation, ham radio has gone well beyond the scope of the basic radio communication that might have been the hobby of your grandfather. Also, amateur radio is the only radio service remaining where participants are encouraged to build, modify and improve their equipment in pursuit of the radio art. This seems to fall right in line with the philosophy of Make.

Scrounging electronic parts
David writes - "Microcontroller hobbyist and electronic project enthusiast can stock up on useful parts by scrounging. Before you throw away an electronic device, take it apart. Examine how it was made and what parts were used. Look for reusable power supplies, microcontrollers, connectors, LCD, LEDs, knobs, meters and even the enclosure.
This article describes a recent scrounging project on a 3Com SuperStack II switch. This Ethernet switch was purchased to use in a home network for $10 at a Goodwill computer store. Unfortunately it was discovered later that the device had very loud fans and was actually only a 10MBit switch. Instead of just throwing it away, it was gutted for parts." - Link.

HOW TO - Make a homemade Electronics Lab for kids
Adam writes - "Today with the help of my four year old son Kai, we built a little experimenter's board because he has been wanting to "learn about 'lectricty" for a while now.
First I found an old piece of MDF from my shed and cut off a bit about 10″ by 6″. Then I bought some screw eyes from the hardware shop. I already had this bunch of colourful clip leads." - Link.

3D Wireless mouse
Neat, here's a 3D IR/Ulrasonic mouse project from students @ the University of California - "The goal of FRE3SPACE was to create a wireless mouse that could operate in three dimensions. In other words, while holding the mouse in the air you could move your arm left or right, up and down, towards and away, in relation to your computer. Our system would detect the 3D position of the mouse and give this information to the PC to be used by other applications." [via] - Link.

Weekend Projects - Make a persistence of vision gadget
There's still enough time to at least -start- getting/ordering the parts for this MAKE weekend project before the weekend is over - in this video Jake McKenzie, Matt Dalton, and Bre Pettis show how to put together a persistence of vision gadget that you can put on your bicycle. Persistence of vision is a perceptual process where your brain holds an image in it's head for a moment. This process is what lets us think that movies have people moving in them instead of seeing all 24 frames a second as individual pictures. This project programs LEDs to flash and appear to make words in the air. Watch the video to learn more and make sure to check out the instructions! - Link & get it on iTunes - Link.

The NES AdPAD
Silas shows you how to mod a NES Advantage pad, with optional add on NES controller, he - "I really like my NES, and i really like the features of the NES Advantage pad :-P Unfortunatly the advantage pad is not good to play with. It requires enourmous movement of your hand to use the joystick, and the A & B buttons tend to get stuck. Also you can't move freely with it, like the normal NES pad. Therefore i desided to add a port to the NES advantage pad, to allow a normal NES pad to be used, and to use the "Turbo" option, and the "player 1 or 2" option... I've called my creation the " NES AdPAD." :-P" - Link.

DIY Mold resistant ultraviolet bread box
Jared writes - "This project came from a challenge I was given by a fan of InventGeek. Basically they chose the most common place and mundane item they could think of and challenged me to improve it in a practical way. So how do you improve a bread box? Well for starters I how about making it more useful than just a nice place to put your bread and we are not talking about putting a computer in it. After modding out our bread box I think we have come up with something terribly practical. Worst case then we have come up with a really clever science fair project for you your kid to do." - Link.

Make a touch screen slotmachine & blackjack machine for your car
Jeez, Max is on a roll, again, this time making a touch screen blackjack machine for a boring start and stop commute - "Okay today I was thinking and figured, why don't I just put a touch-screen slotmachine in my car? I am stuck in traffic 2 hours a day. So that's 2 x 5 days x 12 months = 120 hours a year. "I can gamble while I am waiting at the stop light," I figured. So you are thinking, "Doesn't this guy have something better to do?" Actually, this is the best thing I can think of right now of doing... The CuTOUCH runs on 9 to 24DC power so I figured I just needed to provide 12V from the cigarette lighter plug. Well since I just got a new LG cholcolate phone, I decided it was time to junk my Motorola V3 Car adaptor and put it to some good use." - Link.
