“Sensitive Pulse Induction metal detector which is based on ARM STM32 microcontroller. It can detect metal coih at distance of 30cm, and big metal object at distance of more than 80 cm. Supplies: - STM32F103C8 microcontroller board - WS2812 Addressable LED Strip …
“Overview: So there are plenty of display modules available to work with an SPI bus, mostly based around LED or LCD technology. But I wanted to re-use some old Nixie teck. This Instructable is what I came up with. The …
“Nixie tubes need about ~180Vdc to light up and thus on most devices, a DC-DC converter is needed. Here we designed a simple DC-DC switching regulator capable of powering most of Nixie tubes. The board accepts 12Vdc input …
“DIY sensitive VLF METAL DETECTOR with Smartphone This Metal Detector detects a small metal coin at 25 cm and pot lid at 1m distance This metal detector is capable of detecting small metal objects at great distances. For example, a …
