I'll skip to the happy ending. I can drive the display, the back light, and can read data from the touch screen, but achieving those milestones took much much longer than it should've. This update won't have much info on the actual e-reader project but...
The first challenge was to think about how to arrange the cells. Requirements from my side were: Modular/stackable design to extend the powerbankStable and reliable assembly for portable useDedicated fuse for cells for more security With this requirements...
From everything that was learnt from the hardware development a real / custom actuator had to be developed. After some research the best/easiest solution for me was the 3-Phase driver DRV8305 paired with 6x N-MOSFETs and the PSOC4 Processor. ...
Now it's time to assemble the driver and LEDs in the case. First, I dismantle the original parts from the case. Eight screws in total. Six screws for the LED panel and two screws for the controller.However, I still had to solve the problem of audible...
Friday, 13:25, 02/12/2022 - Yes, "02/12", it took my two days to finish this Project Log since I had to rewrite it time and time again.At first I thought this was a waste of time, but after doing this, I feel like I have a better idea...
Results of a recent study concerning computer technology and people with disabilities indicate that virtual reality tours are effective in conveying information and, in some cases, reducing anxiety. Disabled persons (DP) or disadvantaged people (DP)...
IoT technology revolutionizes the world, everyone is familiar with IoT technology until he is not living under the rock IoT technologies are everywhere starting from our home to offices, and everything is converted or would be converted into IoT systems....
OverviewThis is a scientific calculator I built that uses RPN notation. Features:BCD number format with 1-255 placesInternal accuracy configurable from 6 to 32 decimal placesTwo separate 200 level stacksOptional scientific notationFunctions: (a)sin,...
VideoQuick demo video of the hardware in actionUpdate videoThe beginningAnother year another hackaday prize, (I hope this is going to be an annual affair). After entering last years contest with a project I just happen to be working on at the time I...
Which colours are LEDs sensitive to ? LEDs are nice for illumination, and sometimes, LEDs are used as a colour sensor. But I wished to use a handful of LEDs as a spectral sensor with more channels than just red, green blue... So I soldered 14 different...
Arduino LED 8X8 DOT Matrix Display with MAX7219 The Dot Matrix display is so useful that every enthusiast once came across it. It is a two dimensional patterned LED array that is used to represent character, symbol and images. Almost every outdoor LED...
