The present age is the age of speed and speed is life. The automatic section of engineering is playing a big role in speeding up life. Whose unique discovery is Raspberry pi. Raspberry pi is a series of small computers that have been developed in United...
Reconnected everything & there was obviously a major malfunction. There's either a dead board, broken wire, or a contaminated connector. The LCD was only driven 1 way instead of oscillating. There were bad columns on 1 side while the other...
After some kernel hacking, I was able to get the board to work with my Raspberry Pi!I made some measurements using Room EQ Wizard with the board looping the outputs back to the inputs. REW only seemed to work in 16 bit mode, so the THD+N measurements...
The goal was to plug the monitors into the existing 4B which is used for sound processing. Things were going well with the raspberry pi 1B on a single monitor, but the 4B does not support 1366x768. The problem is it's a very uncommon mode...

The updated LG5 boards just arrived from OSH Park today, so all of these results, such as they are, were obtained with a modified LG4 board. I decided to update the python code that monitors the status of the ups and decides when to shutdown the...
Before you start, make sure you have a working Processing environment on your Pi. [See Tutorial-1] This Tutorial Gave me a bit of a headache, I can not find much reliable information online using the GPIO pins from inside the Processing environment....
[Needed : microSD reader, network, USB-C to USB cable, power source] - Connect to the Raspberry with your computer - Type in the root of the Raspberry "touch main_program.py" and "sudo nano main_program.py" start coding the program. -...
Last weekend I downloaded the software needed to design a printed circuit board, and have it appear on a delivery truck at my front door 5-days later. Viola. That was cool. and since this was my first purchase, they threw in all the...
