How to design and make a high quality HiFi planar speaker with a flexible PCB and planar magnets and later make some 3D printed headphones with these planar speakers.
Very easy circuit of a TRIAC AC dimmer with a DIAC and a potentiometer control. See the schematic and the needed components and make a homemade powerful AC powerdimmer
Took this Universal brushed motor from an old washing machine. See how to control and the wire connection for this motor with DC and AC and get a lot of power out of it.
This is a kit with the vacuum tubes, the transformers and all the needed resistors and capacitors to make a vacuum tube power audio amplifier. Check the schematic, the part list and how to assemble this circuit.
Homemade AM radio based on vacuum tubes and a regenerative coil configuration. It uses 2P2 tubes and it has low power output but it works and we can receive AM radio channels. Learn how it works, see the schematic and test it out.
How a capacitor works. How to measure the charge, voltage, distance and dielectric configurations. How permittivity affects the capacitance. Cool experiment.
Homemade coilgun with separate PCB for each stage. Big coils, huge high voltage capacitors and thyristor control for powerful magnetic field. Very high speed metal bullet detected with phototransistors.
Homemade Vacuum Tube Preamplifier PCB design with analog parts and through hole components. Audio amplifier board with volume control and cool look, purple color.
