This Flip Lamp is going to be a neat project for our Maker’s club at school next year.
LED Choices include:
- Super Bright 10mm LED (PPCOM-08860) 3.0 to 3.4 VDC @ 80mA (£1.36)
- 5V Colour Change 10mm LED (PPKIT3544) 2.7 to 5.0VDC @ 25mA (£0.76) Note: Does not require a CL Resistor.
The Lamp will be powered by a simple CR2032 3V battery. Amazon currently sell packs of 12 Panasonic CR2032 for £3.70 (£0.31 each)
Battery Holder Choices include:
- Coin Battery Holder – Sewable SMB (£1.36) : Flat base could be mounted directly to the jar lid with glue.
- Coin Cell Holder (£0.29): Has posts that would need bending outwards.
The circuit will be turned on and off by a Tilt Switch (£1.76)
