MintyStick! Andrew writes:

Finally, I have succeeding in producing my own variation on the MintyBoost. I found inspiration on this post (http://forums.adafruit.com/viewtopic.php?f=15&t=18225) on the Adafruit forums. It looks like a stick of gum, and I like it, because it’s single-sided, and because it looked like it would be pretty easy to make at home with my toner transfer setup. I call it the MintStick, because sometimes I don’t like to spend a lot of time trying to come up with good names for things. It’s version 3.0 to indicate compatibility with the MintyBoost 3.0 (since it ought to support the same devices).

The XGS AVR 8-Bit system was developed to be a very competitive entry/midrange development kit for the Atmel ATmega644 AVR processor with 64K FLASH, 4K SRAM, and running at 28+ MIPs. The kit includes everything you need to get started developing applications on the very popular platform.

Deddie Lab has two interesting Secret Dice projects. The first one is wooden and the second one is metallic. These dices will open only if the secret code is entered. To enter the code you must tilt the box in the correct ways. When the correct code is entered a servo motor will unlock the box so you can get your reward.  [via]

Kerry Wong needed some ultrasonic range finders for a project so he build his own. He writes:

The theory behind ultrasonic ranging is quite simple. Typically a short ultrasonic burst is transmitted from the transmitter. When there is an object in the path of the ultrasonic pulse, some portion of the transmitted ultrasonic wave is reflected and the ultrasonic receiver can detect such echo.

He provides schematic and code on the link below.

James Floyd Kelly writes about a cool resource: [via]

Found some GREAT information on Bolt Depot’s homepage, including this printable poster that displays all the different bolts and nuts and connectors along with their official names. Click on the Fastener Tab at the top of the website and there are even more resources, including a great tutorial explaining how fasteners are identified (including how to accurately describe a bolt’s length, type, etc.)

Equations for electronics math are available anywhere. If you have the excellent Maker’s Notebook, with its reference section and a calculator, you can plug in numbers and get answers to many of your circuitry questions. So why learn to do such estimates in your head? Because thinking through questions gives you an intuitive feel for them. It helps you quickly sort and refine ideas before committing physical resources to them.

This project is about interfacing a SNES controller and 16×2 LCD to a PIC16f84A to type out which buttons are pressed.
