The probe is just a ATtiny85 board with a handful of components. A resistor and diode help protect the probe and the circuit under test. There are also a few LEDs and a buzzer. The rest of the ...
The secret sauce is in component selection and tuning. Opengeiger uses the BPW34 diode because it is relatively common and has a large surface area, but also because it has a very low capacitance ...
Diode lasers are electrically driven lasers generally made from semiconducting materials. In addition to the optical considerations common with all semiconductors, diode laser structures must also ...
Here I propose a set of principles to guide probe qualification. Mechanism of action. A quality chemical probe has sufficient mechanistic data versus its intended molecular target to enable ...
