Ideas for new labs
Lab instruments
- DDS impedance meter
- Frequency meter -- digital input/input protection/timing
- DVM-- voltage, resistance, capacitance
- digital scope -- with external SPI ADC
- signal generator -- DDS with SPI DAC and concurrent serial control
- Timing: stop watch
Motors
- static helicopter
- slot cars
- swingbot
- elevator
Audio
- ADC, realtime filtering, and parallel DAC output.
- FFT or FWT or DCT to drive spectrum analyser
- FFT spectrogram on TV
- 8 frequency-channel audio filters with light control using PWMs.
- variable delay reverb unit
Games
- Lunar lander
- orbital shooter
Consumer
- led flashlight
- DCC railroad
