Youtuber Bitluni, who we all know for doing crazy projects such as 256 Core Supercluster with the 10-cent Microcontroller or making his own ASIC chip has released a video on his new project - a custom ASIC-powered DIY hologram display. This is not the first time he is making his own custom chip, a month back he showcased his custom chip, which holds pixel data, that can be used to display a hard-coded animation. It was the same as the first time he used the Tiny Tapout project for manufacturing his custom ASCI. If you are not familiar, the Tiny Tapout is an open-source project where you can make your own custom ASIC for a few hundred dollars, something that would normally cost tens of thousands of dollars. the Tiny Tapout offers space in silicon wafers for the designers where we can add our design and get it fabricated with the other designs and as an ASIC chip ready for testing.
The custom chip is capable of driving an 8 LED POV display. Bitluni explained that he dropped his first approach to store the text data within the ASIC chip due to the limitation in which he can only store 20-30 columns of pixel data. Later he finalised another approach where he was able to store 30 words of 7bits, where the highest significant bit is used to identify if the word represents a column of pixels or a whole character of eight-by-eight pixels from a character ROM that's on the ASIC itself. The character ROM within the ASIC contains capital letters, numbers and a few special characters. You can find more information about it on his YouTube channel bitluni.
