Maker Peter Balch has been able to turn an Arduino Nano into an oscilloscope the size of a matchbox. This oscilloscope costs the price of an Arduino Nano (£2 and a display (£3) plus a few pence for resistors.
The simplest version of this device, which he calls the ArdOsc, displays data on a computer screen, but a 1.3” OLED can also be added if you want to use it on its own.
This little oscilloscope can be modified adding capabilities including a logic display, signal generator, and other useful tools according to the needs.
ArdOsc specifications include:
- max 1M samples/second, min 1000sps
- 8-bits per sample
- DC 0-5V; AC +/- 550mV, AC +/- 117mV, AC +/- 25mV
- USB “PC scope” or built-in display
- could be battery-powered
- optional logic display
- optional frequency meter
- optional voltmeter
