Podcast Notes
- Parker
- Wagon Chime Module Repaired
- StarWars Detonator Prop
- RPI3 CM Motherboard USB Hub Saga
- LAN9514
- Page 14/15 of the datasheet
- PRTCTL or Port Control
- Single I/O that operates as a input and output
- It operates as an open drain with an internal pullup
- When the USB Power Switch senses an overcurrent it needs to drives the PRTCTL pin low
- Then the LAN9514 also drives the pin low
- This PRTCTL needs to operate the enable pin on the USB Power Switch
- MP62551 or TPS2054B
- Would need 4 MP62551 but I can provide 2A total verse 500mA
- Operates the way the PRTCTL needs
- Possibly breaking this HUB circuit into its own to prototype?
- LAN9514
- Improving the Prop Dev Stick
- Stephen
- Beginning the eq build. There is a lot to do so it is taking a bit of time
- Gold fingers and connectors – They work!
- Trying a special coax connection – Different rings on top and bottom
- R.F.O.
- Bluetooth chip doesn’t need a battery because it harvests energy from the air
- Wiliot
- Embedded in consumer products to provide easy access to a digital manual when the original paper version is long lost, or it could be put on a clothing label and used to communicate the optimal settings to a washing machine
- $30 million financing from Amazon and Samsung
- Possible release in 2019 but they are shooting for 2020
- HOWMAX30 – MAX-30 Single User Earplugs
- Incorrect part listing on Amazon leads to hilarious reviews
- Bluetooth chip doesn’t need a battery because it harvests energy from the air
