  • Hey! I made one of these myself! Mine was a lot simpler, using the Jimmie P Rodgers Open Heart kit and the Sparkfun “Pulse Sensor” ( part SEN-11574). I hacked the code the Arduino runs together from the demo stuff that came with the two pieces of hardware. Works like a champ on a 9-V battery with a pouch my lovely wife sewed together to hold it. It might not be exactly as accurate, but you didn’t need to stick anything on your body.

  • Heh. I come from the other side of what seems to be a pretty big divide in the robotics world – I’m comfortable with software, less so with hardware. The easiest way to learn a new development tool is to actually do a project with it. The problem often comes down to finding a project hard enough to be interesting, but simple enough to get your arms around. For learning new programming languages, I"m a big fan of Project Euler ( https://projecteuler.net/ ), a series of increasingly difficult math problems meant to be solved with the help of a computer. If you can get 25 or so of these babies solved, you’ll have a pretty strong foundation in the new language of your choice.

  • Cigarboxnation.com is a great source for cigar boxes, in a wide variety of shapes and prices. My current (not yet completed) project uses one. Cigar boxes are easy to work and relatively cheap.

  • Oops.

  • Heh! This is a really fun thing. I got it working with an Arduino, a 9V battery, and the Open Heart Kit from Maker Shed ( http://www.makershed.com/products/open-heart-kit ). Video with source code links is here ( https://www.youtube.com/watch?v=guZ9PStlZfk ).

  • Wonderful essay. Mr. Tolkein’s quote “He who breaks a thing to find out what it is has left the path of wisdom” infuriated me when I read it. Breaking things is he path of wisdom.

  • Would this fold if used as a guitar neck? Is it strong enough to support one or more strings, tuned to make music?

  • A simple and reliable kit. The only trouble I had was that I tested it on a breadboard with two separate regions, served by two different power rails. So it looked like it wasn’t working until I put my jumpers into the correct holes. So, pro tip: study the anatomy of your breadboard before testing.l

  • This was a fun kit. It went together quickly with no major issues, even though the order of assembly is a little different from what I’m used to . Usually I’ve soldered in resistors,caps,sockets,switches,rheostats, battery. The kit instructions go capacitors,sockets,switches,rheostats, resistors, batteries. Inserting the Arduino is tricky, since her socket is closely surrounded by other components. I sure wish if it had an IR LED that would talk to the Nebulophone.

  • Hey! The BNC->BNC cable is the right answer for my oscilloscope. You can also use the BNC->alligator clips connector to hook this thing directly to a little speaker. I’m using a 2" transistor radio speaker much like Sparkfun’s COM-09151. Actually hearing the signal made it easier to figure out how sweep and other features worked, and it’s way cheaper than an O-scope too!

No public wish lists :(
