I have decided to build a handheld digital compass for orienteering, with altitude and temperature functions. I haven’t used a compass in decades, and some folks have never used one, so I thought I’d post a link to a great tutorial describing the parts of a compass, and how it’s used. Enjoy! http://www.nwcg.gov/pms/pubs/475/PMS475_chap4.pdf

One of the goodies I received from Hacktronics the other day is the HDPM01 module. The HDPM01 module includes a pressure module and a compass module. Apparently, there is also a barometer and a temperature sensor on this module. The HDPM01 pressure module includes a piezo-resistive pressure sensor and an ADC interface. It provides 16 …
Want to try out your designs virtually, before committing to hardware? You can sim the Arduino, and many other microcontroller platforms at http://www.virtualbreadboard.com/ See the video at http://www.virtualbreadboard.com/videos/VBB_5_ArduinoShow/ArduinoShow.html
This past weekend I picked up a very handy gadget, a Helping Hand. Two adjustable alligator claws to hold circuit boards or small work pieces, a holder for my soldering iron, and a LED lighted magnifier make my Arduino experimentations a lot easier. $10 at “Workshop Tools“.
A box arrived from Hacktronics today. Inside was 4 1w RGB LED’s, 3 LM317 voltage regulators, 10a Power MOSFETS, 7 npn transistors, resistors, a compass module, 5 potentiometers, and a 12vdc 1a ac adaptor. Over the next few days I’ll be posting pics, videos and code.
While I’m awaiting the delivery of my 1w RGB LED’s and the MOSFETS to drive them, I thought I’d share some examples of projects built by Miguel Sánchez that I’m a big fan of.
