Editorial interest 82/100 Selection signal · not a rating of the site

MIJING STUDIO presents a programmable magnetic-field coil device controlled through a phone over Bluetooth.

Landing page captured for the 2026-09-21 issue.

For: Magnetic-field researchers and experimental electronics users
Worth noticing: The controller supports 0–1 MHz output, 16 channels, three waveforms, BLE control, and 2.4G Wi-Fi OTA updates.

Field notes

The control page exposes a concrete operating model rather than a generic product pitch: users can add channels, set durations from 0.5 to 60 seconds, mix or cycle frequencies, save up to 20 presets, and apply settings to a connected device. Audio mode uses a second classic-Bluetooth connection, while the device accepts firmware releases over 2.4G Wi-Fi. The accompanying library is explicitly presented as reference material, not medical advice.
