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
