- Synth update. PCBs should arrive next week.
- To match the transistors for the synth, Stephen is going to use his transistor matcher to test them. See Figure 3.
- Stephen needs 6 matched BC547C transistors. He is going to buy 100 transistors ($5.70) so that he can pick the best 6 that match.
- The Open PLC that Parker and Stephen have been talking about is finally doing something!
- Building a hand place bench
- Controls sensors and barcode scanner
- Stephen is also going to use it in a museum project
- Have we gone too far with RGB LEDs? Razer Chroma Mug holder.
- Samsung might just be a bunch of pyros. Fire Breaks out in Chinese factory that makes Samsung note 7 batteries.
- Computers that can survive on the surface of Venus
- Sulphuric rain is easy, Not being cremated by 470°C (878°F) or crushed by 90 atmospheres or 9MPa is hard.
- Longest survival time for a human-made object on Venus was 127 minutes, back in 1981 when the Soviet spacecraft Venera 13 landed there. Took the only color picture of the surface.
- Semiconductor Silicon Carbide electronics, support high temperatures.
- NASA’s Glenn Research Center developed high temperature wire bonding.
- GEER—the Glenn Extreme Environments Rig. Can simulate the surface of Venus.
- Oscillator operated for 521 hours before they turned the simulator off.
- The Footprint Files – Properly marking parts with silkscreen – Capacitors. Look for the article Parker will be writing next week!
