Tabletop Christmas Tree with LEDs
THIS WORKSHOP HAS NOT BEEN RUN SINCE 2017, IS AVAILABLE FOR ARCHIVAL PURPOSES ONLY. ANYONE SEEKING TO ADAPT THIS WORKSHOP SHOULD CONSIDER THE FOLLOWING INFORMATION.
WARNING - This workshop makes use of small coin cell/ button batteries.
In December 2020, the Australian Government made mandatory safety and information standards for button/coin batteries and consumer goods that contain button/coin batteries (the standards). The standards included an 18 month transition period and became mandatory from 22 June 2022. From 22 June 2022 manufacturers, importers, wholesalers and retailers of button/coin batteries or consumer goods that contain button/coin batteries supplied to Australia, must comply with the applicable Australian mandatory safety and information standards. Supplying or selling non-compliant products to consumers in Australia is illegal. The four mandatory standards are as follows:
• Consumer Goods (Products Containing Button/Coin Batteries) Safety Standard
• Consumer Goods (Products Containing Button/Coin Batteries) Information Standard
• Consumer Goods (Button/Coin Batteries) Safety Standard
• Consumer Goods (Button/Coin Batteries) Information Standard
This workshop was devised as a Christmas special in 2017, and reprised the next year.
Laser cut 3mm acrylic parts are held together with locating rings, though a few spots of acrylic glue are usually needed to make it stable. The multilayer base is held together with clips, also cut from 3mm acrylic, and a coin cell battery held in place with tape.
A simple circuit (without a switch) brings power from a CR 2032 coin cell battery to an LED at the top of the tree. If battery safety is a concern, then the multi-layer battery holder made in the base of the three can be glued over, but this makes battery replacement problematic.
Contact between wires and the battery terminals is assisted by using sticky tape to fix the bared ends of the wires in place.
A battery will last about 24h (depending on the colour of the LED).
