“You can get your hands on some very interesting components when disassembling old electronics. One such I’ve found was this VFD (Vacuum Fluorescent Display). Trying to reverse-engineer the controller was, however not the way to go as all ICs …
“The process of making a salvaged VFD Arduino-friendly. You can get your hands on some very interesting components when disassembling old electronics. One such I’ve found was this VFD (Vacuum Fluorescent Display). Trying to reverse-engineer the controller was, however …
“An astronomical clock with 16 functions, with only three shift registers Years ago I ordered 12 7-segment displays. I wanted to make a clock that displayed the time and date. But it appeared that it took too much digital IC …
“This cube is easy to build with no circuit board and minimum external components; and it comes with a lot of animations and effects. This is the third and final project in a series to see how much LED cube …
“The displays are driven with a daisy chained shift register. The converter on the left generates the 24V rail and the centre converter provides 1.5V for the filaments. Both converters can be disconnected via jumper for initial setup and …
“In some situations, in your designs with Arduino and microcontrollers, you can use a shift register like 74HC595 to directly trigger LED, LED array and displays, but if you check the datasheet, you will see that you need to be …
