Part 14 Design and Build a Mylar Electrostatic Telescope Make the Electrostatic Nodes

Part 14 Design and Build an Aluminized Mylar Electrostatic Telescope Make the Electrostatic Nodes by Professor Robert George Mertens, Ph.D. In Part 14, we cut and solder the electrostatic nodes that will carry the electrostatic fields to bend the Mylar mirror. This is a series of videos that will document our historical experiment, if it's successful, to design and build a workable and functional Newtonian telescope made of Aluminized Mylar and electrostatic fields. The Mylar we'll be using in this experiment will be 2 mils (0.002 in) thick, and have a fine (about 5 - 10 nanometer) layer of evaporated Aluminum. Electrostatic fields will be used to manipulate the shape of the mirror, and even make corrections. Materials: 1. Proto board, electronics. 2. Various resistors, capacitors, inductors, diodes, transformers. 3. NE555 Timer, LM339 Comparator, 7474 D-Flip-Flop, 74123 Monostable Multivibrator, LM358 Operational Amplifier. 4. 2N2222 (PN2222) BJT. 5. Power supplies, 18VDC, 5VDC, 12VDC. 6. Stepper motor w/driver chip. 7. Copper sheet roll. Tools 1. Voltmeter 2. Oscilloscope 3. Electrical leads 4. 3-D Printer. 5. Common tools (screw drivers, pliers, wire cutter, wire stripper, etc.). 6. Soldering iron. Software/Hardware 1. Computer w/internet 2. Web browser 3. Access to youtube (to watch this video series) 4. LTSpice Simulation software. 5. FreeCAD. 6. KiCad. Music: No music this round.
