Kit for the Stackable LED Christmas Tree
A kit of parts to build a single board for the Expandable Christmas Tree. Includes the PCB, IC, capacitor, resistors, high-brightness LEDs (three green, three red and three white) and connectors.
As well as the specified 1kΩ resistors, we are including 820Ω and 220Ω resistors. These can be used with the white and red LEDs respectively, to better match their brightness to the green LEDs.
Refer to the November 2018 issue for assembly, set-up and operating instructions. The Digital Interface Module in the same issue can be used to drive the Tree (http://www.siliconchip.com.au/Shop/20/4750).
You will get a discount if you order more than one. Price breaks are at four ($32 total), 18 ($126), 31 ($199) and 38 ($229).
Note: photo shows assembled kit.
