Episode Details
Back to EpisodesThe Amp Hour #462 - Boat Anchors
Published 6 years, 5 months ago
Description
- Chris has almost finished reading Eccentric Orbits and has been working on satellite comms in the meantime.
- Flat earther documentary on Netflix, Behind The Curve
- Satellite internet is en vogue again, with Elon Musk launching Starlink and pasts guests like Maarten Engalen (Hiber)
- 5G distances are pretty short (depending on the implementation)
- Discontinuing 3G in Australia
- GSM wasn't a big factor yet during the timeframe of Eccentric Orbits (1993 - 2002ish)
- Shahriar did a review of the Siglent SVA1032X and Chris is getting a demo unit soon!
- The HP8753ES was another one on Chris' watch list, but it's a "boat anchor" (heavy piece of test equipment)
- The TDS220 was one of the earlier scopes that changed the standard for how much space it took up on the bench top.
- Dave advertises when there are auctions on the EEVblog forum "Buy / Sell" section. This is a good way to find an auction house to sign up for future notifications.
- Gerbers were a standard format used for photo plotting. The aperture was how wide the light beam was opened as it passed across the board.
- Chris has a "residency" where he gets to try out a Bantam Tools machine. He talked with MG about milling circuitboards a couple months ago.
- The Dragonfly is another machine that supposedly "prints" layered PCBs. It would work well as a super crisis option, but probably not for most PCBs.
- The plan is for Chris to mill out antenna shapes, like those shown in TI App Note 58 (AN058)
- Dave and David have been working with the Richtek USB C processor
- Seeed Studio has some new boards coming out with a RISC V Bumblebee core, made by Giga Devices. The part number is super confusing!
- ARM is allowing custom instructions to be added to the Cortex cores, ostensibly because they're feeling pressure from the RISC V option.
- In Dave's new video about LED lights flickering, the part he was looking at was marked the same as a datasheet, but had a completely different implementation.
- Chris released Getting To Blinky 5.0 videos
- A writer at Digikey tore down and reviewed a $17 power supply
- The device we were discussing on episode 460 was a process meter (Dave made a video about it). It ended up selling out
