New Kit Options Now Available!

I’m excited to announce some additional options for buying the Analog-Style LED Clock Kit!

To save on the price of the kit as well as the cost of shipping, we are now offering a “Barebones” version of the kit. It does not come with a printed manual or a power supply, and the frame is optional. This may be a particularly attractive option for our international customers. Most customers outside the United States would likely not be able to use the normally included power supply and would have to supply one of their own anyway.

You can now buy either kit with a pre-assembled printed circuit board. Absolutely no soldering required! You will still need to paint the frame, attach the numbers and install the PCB into it. This is a great option for those who feel uncomfortable with the soldering part of the project.

I’m also pleased to announce that all our kits and parts are now RoHS compliant!

Be sure to check out the available options for our Analog-Style LED Clock Kit as well as the “Barebones” Kit!
