- RPI3 Compute Module
- PCM5122 Routed
- LAN9514 Routed
- single upstream USB port on BCM2835
- Pin 44 Ethernet 25MHz output
- Pin 31 LAN RESET
- Information found on the Raspberry pi forum
- Need to add USB current limiting
- CM3 HOME
- Guido Ottaviani made his own carrier board I have been looking at for inspiration to solve some of the final problems
- 1473149-4
- Connector being used to socket the RPI3 Compute Module
- Stephen
- Crazy EQ amplifier design continuation
- Opted to go with a card edge solution for each EQ band
- Each band connects via a 36 pin PCI-Express connector
- +12V
- -12V
- +5v Reference
- -5V reference
- Gnd
- 4 In Signals
- Cut
- Boost
- Potentiometer pin 2
- 21 modules in total. 1 module has all of the power and main signal in/out from the amp. This sends all of the other modules their power/ground and signals.
- Need to rethink things - Feedback loops are crappy.. Need to go with a 64 pin solution
- Beveled edges and Hard Gold plating discussion in a future episode
- R.F.O.
- Debugging I²C with Hardware
- I²CDriver is a crowdfunded effort by James Bowman
- Open Source tool used to easily drive I2C devices
- Controls with a GUI, command-line, C and C++ using a single source file, or Python 2 and 3, using a module
- Low Cost Reverse Polarity and Over Current Protection
- Jeri Ellsworth's new video on reverse bias protection
- Has a Robbie Robot on her desk!
- Methods
- “One of the options is to do nothing”
- Diode input
- Exploding Diode
- PMOS FET
- Low rds on - “almost not there”
- Body Diode - Watch out for this
