Summary edit
| Description |
English: I'm still exploring the basic behaviors of transistors and capacitors, since I've never seen them explained terribly well beyond capacitors store charge and transistors switch and amplify! I'd gotten the Parallax BASIC Stamp HomeWork board for Christmas, but never got around to programming it since, well, it's programmed in BASIC, and the BASIC tokenizer doesn't work under Linux (well, not without some trickery, anyway). Compare that with the Arduino, which can be up and running in a matter of minutes, and uses C/C++ and the GNU toolchain. I picked up the voltmeter at Ax-Man Surplus. It looks nifty and chunky, but unfortunately the needle isn't damped at all, so it wobbles a lot when voltage goes on or off. It's an EMICO NF2C-2137. The company is "Electro-Mech. Inst. Co. Inc., Perkasie., PA., U.S.A." Ah, the goold old days, back when the period was the "e-" or "i-" prefix of its day (and yes, there was really a period after "Perkasie" on the label).. |
