I bought this “Spherical Rotation 56 LED Lamp POV Rotating Clock DIY Part+TTL Serial Downloader” from eBay, and it came without a manual, of course. So in this video series I will be building the kit until it is complete, working and reprogrammed.
In this video I will be reprogramming the STC chip with new texts and new images. The hardest part about reprogramming it, was finding the software, so here it is: http://files.banggood.com/2016/08/SKU343833.rar
The second hardest part was getting a USB to TTL adapter to work. The one which worked for me so far is this one: http://www.ebay.com/itm/CP2102-USB-2-0-to-TTL-UART-Module-6Pin-Serial-Converter-STC-Replace-FT232-Module-/381374541932
If the above link expired, search for CP2102 on eBay, and you’ll find the correct adapter.
