New TOH idea by bill_klpd, Multimeter TOH.

Seems that i started to think about this further.

First, sketching the UI:


Block diagram of the electronics part: (First draft)


First 3D sketch:


HW Specs:

• Voltage measurement ranges 200mV, 2V, 20V, 200V DC (AC TBD)
• Current measurement 200mA, 2A (TBD)
• Resistance measurement 200, 2k, 200k, 20MEGohms (TBD)
• Possibility to measure low-side current and high-side voltage at the same time --> Power (W) measurement.
• Isolated from phone (floating) should be safe to keep USB charger connected while taking measurements.
• Fused current measurement

SW Specs:

• Continuous measurements with adjustable rate
• Min/avg/max display
• Single shot measurement when in hold mode
• Beep when new min max value, or beep when short in Resistance mode.
• Logging of readings with timestamps
• Trigger events with alerts also possible TBD
• "Plotter" view on separate page of latest results TBD
• or simpler graph view in main page TBD
