UV-C bulbs use a dab of mercury plus a glowing hot filliment in a low pressure tube of glass to generate ultraviolet light that peaks around 253.7 nano meters, the optimal germicidal wavelength in the UV-C part of the spectrum. Not to be...
#include #ifdef __AVR__ #include #endif // Which pin on the Arduino is connected to the NeoPixels? // On a Trinket or Gemma we suggest changing this to 1 #define PIN 6 // How many NeoPixels are attached to the Arduino? #define NUMPIXELS 48 // How much...
Sizing Your Solar Power SystemOne of the first things that comes up in a solar powered design is how to design the power system. The three main questions to be asked and answered are:How much power do I need? How many solar panels do I need? What size...
I've had comments regarding the validity of using Geiger–Müller Tubes for a cosmic ray (muon) detector. Pointing out that Photomultipliers and scintillation panels are best, and yes the are far more effective. However, they are also expensive,...
Plug in your Cat's nervous system. Connect the Photon to your other components. I do this by using 3x20 breakaway right angle headers where several rows have been shorted together to be power and others to be ground. This lets me better organize my components.Pin...
Wire as follows: Both potentiometers Pin 1: 5v Both potentiometers Pin 3: ground Left potentiometer Pin 2: A0 Right potentiometer Pin 2: A3. Note that they have two channels, and all three wires have to connect to the same channel...
To modify a Quartex Q-80 movement, first obtain the Q-80 variant crazy clock board. If you make the boards yourself, you must get them made with 1mm thickness. 1.6mm, which is the "standard" thickness, won't fit properly.
