- PinoTaur
- MCP23S08
- I/O Expanders Verse Shift Registers?
- Wagon Tach Project
- 3D printed the housing
- Need to run the wire from the distributor to inside the cab
- To knock down the distributor signal
- In series diode to prevent negative flyback? voltage from affecting circuit
- Resistor divider

- MacroAmp Testing
- Used a variac to bring the amp up to voltage
- Found some of the resistances were too high
- It can be difficult to determine what a transformer tap will produce - I chose to guesstimate and fix it later...it works
- Higher gain when powered from the transformer. About 100x gain
- Tested into a Power amp - Works
- HUGE ISSUE: MICROPHONIC TUBES
- Next steps - Get everything in the enclosure. Wire the output transformers
R.F.O.
- Chip component gets heat out of tight spots without leaking electrons
- TT Electronics has introduced a surface-mount component designed exclusively to get heat out of tight spots.
- SMD thermal junctions that can be placed with a pick and place
- Can use creative thermal paths instead of more traditional “heat planes”
- Server maker Super Micro to ditch 'made-in-China' parts on spy fears
- Check out Episode 142 of the MEP with Misha and Church
- This a security move or just money due to tariffs?
- Was there something TO the Bloomberg article that caused this to happen behind the scenes?
- On better datasheets
- Suggested alternate reading: https://www.embeddedrelated.com/showarticle/809.php
- Manufacturers could provide a “legend” or “guide” for their family of datasheets
- Don't just photocopy your old datasheet and slap your name on top. Do just a little bit of effort and make a new datasheet. Also if you do photocopy anything AT LEAST DO IT STRAIGHT.
