This soldering exercise trains your own soldering skills and can be used as a night light or decoration after completion. Thanks to its compact size and power supply via mains adapter or battery, the light can be conveniently taken anywhere.
The brightness of the LEDs can be controlled using a push-button and self-locking switch. Alternatively, any infrared remote control can be used for this purpose.
Special features:
- can be made by yourself
- simple switching
- two positions for brightness control (12 or 18 illuminated LEDs)
- can be controlled alternatively with any infrared remote control
