Mini HV UPDI (High Voltage Unified Program and Debug Interface) programmer for the new megaAVR 0-, tinyAVR 0- and 1-series microcontrollers built on ATtiny1604/1614 based on the design and the firmware by Dlloydev (https://github.com/Dlloydev/jtag2updi). The Mini HV UPDI programmer will enable you to use the additional configuration settings for the UPDI pin without the fear of getting...
<p><strong>Attention!</strong> I strongly recommend coating the board with varnish after assembly and using it only in a dielectric case.</p>
<li>High voltage: 400V RMS</li>
<li>Low freq: <100kHz</li>
<li>Input selector: triangle\star\isolated differential</li>
A modern take on the original Tesla Coil using electronic circuitry; this specific type is a Dual Resonance Solid State Tesla Coil. This is based on Steve Ward's original design at http://stevehv.4hv.org/SSTC5.htm and updated for modern and easily available components.
When a Townsend avalanche is created in a Geiger-Muller tube by some high-energy particle, the signal is inverted and sent to the trigger pin of a ne555 in monostable mode (T ~ 2s), whose output is sent to the clock-enable pin of a decade counter driving the cathodes of a Nixie tube, while the clock signal of the decade counter comes from the ouput of another ne555 in astable mode (f ~ 1-50Hz thro...
