There is much pleasure in useless knowledge. Bertrand Russell. Rheoscopic Fluid (mica in suspension). May 19, 2015 Amateur Science. I mentioned in my Maker Faire wrap up post that I had spoken with Ben Krasnow, the science guru behind the Applied Science. Youtube channel. If you haven’t watched his videos, by all means, go over there and give it a whirl. Between playing with chemicals, low temperatures, rockets, X rays, and electron microscope, it’s simply humbling. What is a rheoscope, you ask? For unde...

There is much pleasure in useless knowledge. Bertrand Russell. Using a SainSmart LCD panel with the Arduino 1.6.3 IDE…. April 22, 2015 Arduino. Yesterday I experienced some frustration. With the SainSmart I2C LCD Module. The basics are essentially this:. The LiquidCrystal library that ships with I2C is probably fine for connecting to LCDs with a parallel interface, but it does not support I2C bus displays. You can download the code by clicking here. This is kind of a pain,. The commands you type also var...

There is much pleasure in useless knowledge. Bertrand Russell. Another try at an Arduino Based Morse Beacon. November 14, 2009 Amateur Radio. Back in 2008, I blogged about a stupid program I wrote to implement a Morse Beacon on the Arduino. 1) { if (p and 1) dash() ; else dit() ; p = p / 2 ; } delay(2*DOTLEN) ; return ; } } /* if we drop off the end, then we send a space */ Serial.print("? Well, I couldn’t leave that alone, witness this…. You get about a 500hz tone, and it works really well. Then you mig...

As a first (but not particularly challenging) test, I downloaded my Morse beacon. Code It worked fine, with no changes: the Teensy even uses pin 13 to flash its tiny onboard orange led. Pretty nifty. The Teensy family is well supported with platformio as well. Laquo; Interested in the history of my callsign: K6HX. 4/27/2015 at 10:07 am.
