Bits Flying In
- Parker
- Ordered Compressor IoT Board. Will start on the Software side.
- Wrote an article about PCB board outlines and what to watch out for. It is waiting for Stephen to look over it and make sure it is not missing anything.
- Defining planes in DipTrace with board outlines vs Eagle.
- Parker has Vias that haunt him. Bad pinout designs for ICs can cause unnecessary vias in board layout. The LSM9DS1TR is an example of one.
- Stephen
- Synthesizer Update
- MIDI code problems and triumphs
- Audio clip of before tuning and after tuning.
- Frequency doubles for every ½ volt you put in for the VCO (Voltage Controlled Oscillator).
- Zener diode - Zener diodes leak - caused huge calibration issues with synth.
- The Zener diode was installed to prevent over voltage of the ADC.
- Lower frequencies were really sharp, higher frequencies were flat. Plot of IV curve now matches with data sheet.
- Basically Stephen characterized the Zener Diode leakage current!
- Article series for the synth - on modules and theory of operation. Block diagrams and explain how these work.
- Synthesizer Update
- Pick Of the Week (POW)
- Doomed Thermostat
- Honeywell Prestige Thermostat
- STM32F429 processor ARM9 processor
- This is starting to be the 1337 version of blinky. Hello Doom?
- It runs doom!
- Doomed Thermostat
- Rapid Fire Opinion (RFO)
- TI reference design TIDA-01243
- USB Type-C™ and Power Delivery Minidock With Video and Charging Support Reference Design
- 20V 3A (60W)
- Procedural generating random medieval cities - HackADay
- Great for D&D.
- Generate a city on the go.
- Cool color scheme.
- 3D printing D&D figurines? Stephen goes back on his opinion of 3D printers.
- Raspberry Pi named a finalist for national engineering award - Electronics Weekly
- Raspberry Pi has been named as one of this finalists for this year’s coveted MacRobert Award, the innovation prize awarded each year by the Royal Academy of Engineering.
- 1% of the Global PC Market
- TI reference design TIDA-01243
