Digital Multimeter
At the end of the Spring 2025 semester, the larger Digital Multimeter Project had constructed a PCB device that was capable of measuring DC voltage of up to 200 volts and DC current of up to 5 amps. It had a range selection dial, a central processor with two external ADCs, easily replaceable fuses, a large liquid crystal display, all for a rough cost of $60 per unit. The project was sponsored internally by OSHE and was completed under budget. The Mini Digital Multimeter Project presents a compact measurement device, about the size of a credit card, which is capable of capturing DC voltage measurements of up to 30 volts, DC current measurements of up to 1 amp, and resistance measurements up to 100,000 ohms. Designed with affordability and mass production in mind, the device will maintain a bill of materials of $10 and prioritize surface mount components while minimizing through hole components where possible. Switching between measurement modes will be easy and intuitive, with a clear mode selection button and indicators to guide users to their desired measurement type. This device will also employ numerous safety features such as fuses, graphical warnings and an enclosure to protect users and ensure safe operation.
