Using Arduino to get the cost of probeware down (for science education).
Vernier's cheapest interface is $61 and handles one sensor: www.vernier.com/mbl
Arduino Uno is $30 and has 6 analog inputs: www.sparkfun.com/products/9950
Our goal is to interoperate with this curriculum: www.concord.org/activities/research-focus/probeware
Arduino clone with real-time clock, microSD socket, radio module and USB interface. The layout is designed for easy assembly and maximum compatibility with the Arduino Uno, with additional functionality being compatible with the Arduino Mega2560. The optional LM61 temperature sensor is not fitted, nor is the 5V regulator.
Version 2.1 features a few minor of improvements over version 2; the most significant is the addition of Microchip MCP2200 USB to UART converter.

Space was limited in my room so I decided long ago to remove my bed and build a lofted setup.
I do a lot of tinkering so I built in a U shaped desk that extends more or less around the full perimeter of my room with lots of space to work on things. My desktop setup lies directly underneath my bed and on the opposite side I have a soldering/electronics station.
I recently underwent a few hardware upgrades for my desktop which include a liquid cooled 6 core, 64 gb RAM custom machine and 3x 27" Achieva Shimian Korean IPS displays. These are mounted to the wall with monitor arms and can be pulled closer to the edge of the table if needed. The setup works really well for my 3d modeling and coding work.
They are also backlit by a RGB LED strip powered by an Arduino R3 and Python based client on the desktop which changes color according to the color on the screens. I find that it helps a lot with eye strain and adds a great ambiance to the room.

$9 ARDUINO lesson 2. I copied the code from the web site but had to add the int definitions. push the button and light the LED!
I know everyone has done this before. RFID and arduino that is. But looking at the example code it looks like the antenna is always in receive mode. I am not sure how this affects the life of the chip / reader but I thought of adding a way to detect human presence before activating the receiver.
I found some little IR heat detector (here: www.allelectronics.com/make-a-store/item/IRD-10/INFRARED-... and tossed together some analog read code and viola. Now when the IR detector detects over a certain variable heat temp it activates the RFID reader.
I will post the code and write up on my blog.
This is a fully Arduino-compatible setup based on the Arduino breadboard except with a USB to serial converter and an RS232 level shifter instead of the FTDI chip. I used the parallel cable I'd made previously to burn the bootloader, then I was able to program it and to communicate with it via USB. This was all done using the normal Arduino software on Linux.
Our third Arduino 101 class at Tam Makers went really well. I taught this evening course with co-instructor Donald Day on Thursdays, from June 16 to 30, 2016, at the woodshop in Tam High School in Mill Valley.
We worked with an enthusiastic group of seven students, including adults with diverse backgrounds, as well as a couple high school students. Our partner Geo Monley worked both as a mentor and as a student during the hands-on sessions.
We started the class at 6pm, by giving students an overview of how circuits work. We then learned how to use a multimeter, how to solder electronics, and how to control rainbow-colored NeoPixel lights.
Students seemed to really enjoy this class and told us they learned a lot from it. Several expressed an interest in taking intermediate and advanced classes in the future. This is one of our first maker courses at Tam Makers, and we’re really happy that it is going so well; we look forward to teaching more classes in the fall.

Wow, could not be simpler. Sonar unit streams the distance continuously on an analog line. 3 Wires, vcc, gnd, A0.
The next part of my nixie tube clock is some kind of real time clock that can keep track of time. The DS1307 is tiny and does just that. While the final clock may use GPS to get an accurate time, odds are it will be used to set one of these in case GPS reception is lost. The clock seems accurate - it's kept time for a day at least!
I'm using the AVR's TWI hardware rather than Wiring library's I²C code as I may not use an Arduino in the final clock (but they're really handy to prototype with!).
The LCD shows pretty much what the nixie tubes will: date and time, both six digits.
An add-on Gilroy’s been toying with for everybody’s favorite Arduino enclosure, this makes it simple to change out a 9V battery when your project needs the base & lid to stay together.
a $30 embedded development kit.
program it in C. the software is free and there is a lot of free library support in source form.
Few lightings taken with my 30D and the arduino lightnig trigger.. still mounted on the Breadboard :) ..
I bought this very cool book from the Computer History Museum, that's the KENBAK-1.
This is an Arduino-based emulation of the KENBAK-1, considered by some to be the first "personal computer". It was first advertised for sale in the September 1971 issue of Scientific American (forty years ago!).

Finding the traditional USB Arduino a bit too big? This board includes everything the larger board does (except the USB to Serial portion) and does so in 1/6th the space (18 x 33mm). With the reduced size and cost it makes slipping an Arduino into almost anything possible. It also comes with the headers unpopulated letting you either solder in headers (for use in a breadboard) or your own wires directly to the board.

Part of my plan to make a low-power wifi-enabled magnetometer for AuroraWatch UK. This shield is designed for Calunium, but will work with full functionality on the Arduino Mega2560. It will also operate on a standard Arduino but flow control and some of the GPIO features of the RN-XV are not available.
The shield uses logic level translators on both the inputs and the output from the SD card. This means it can be safely used in situations where there are 5V devices on the SPI bus (eg MicroMag3), see blog.stevemarple.co.uk/2011/10/interfacing-33v-devices-to... for a discussion of the problem.

This is something I had been meaning to complete for quite a while. I needed something that was portable, clean and easy to store random things in to prototype stuff on the fly.
The Proto Desk allows me to sit on the couch with my laptop and arduino and mess around.
