Part 1 Design and Build a Mylar Electrostatic Telescope

Part 1. Design and Build an Aluminized Mylar Electrostatic Telescope by Professor Robert George Mertens, Ph.D. For more videos in this series, please visit my website, at https://www.wherearemyplacebos.com/ga... There are more videos on various subjects on my youtube channel, at    / @robertmertensphd   In this first video, we've been working on the concept for several years, although this isn't the first time this experiment has been done. There is even one Aluminized Mylar telescope that was funded by NASA and launched into space, now in orbit, but imperfect in its design and performance. 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: (This list is, of course, incomplete. There are many individual items needed to accomplish this experiment, and the list is long. In addition to all of these items, it would help to have a good deal of knowledge of electronics, mechanical systems, feedback control systems, high-voltage electronics, and much more.) 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. Tools 1. Voltmeter w/high-voltage probe. 2. Oscilloscope. 3. Electrical leads. 4. 3-D Printer. 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.
