Outline Tens of thousands of people creates they own programs on brainfuck esoteric programming language. Thousands - creates they own brainfuck compilers or emulators to run their creation. But the only one man tries to create Brainfuck Relay...
HIKVISION DS-7316HI-S Table of Contents 1. Symptoms 1.1. RS-232 interface fix1.2. Firmware restore 1 Symptoms The HIKVISION DS-7316HI-S is an NVR supporting analog CCTV cameras which I got for free. It was declared to be broken and indeed was failing...
Overview Internally, the sculpture is organized into modules of four motors. Every module has a circuit board with the motor drivers, power regulators, comms interfaces, and two microcontrollers. Each microcontroller is responsible for the position...
Here's a video of the Z axis lower limit optical detector in operation. Upper is similar. On the lower, I had to swap the 3-pin connector to the outside, else the router base plate would hit it on the way down. I made the interrupters from 3/4 x 3/4...
Update: I added that stubborn LibreOffice pie chart at the end ;)What does it take to be a winner? Getting an entry in early sure helps.I think projects with pictures, videos, and clear details, look like they get more attention.Here is the competition,...
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...
The Mission I needed some stripboard for a prototype. Even in the age of Oshpark and JLCPCB I still find stripboard prototypes to be useful. I can make them in an afternoon and they are easy to modify. But, where to source stripboard? ...
Consumer CNC machines and open source firmwares have come a long way in a short amount of time but still lack some features that I wanted after obtaining my first CNC. Although MPG handwheels are common on machines running Mach or LinuxCNC, they...
A new and improved spreadsheet is now sorted by project, instead of by contest, making it easier to sort and analyze (no more double entries!) Get the spreadsheet, it looks much better. Download the new one here. It has presorted sheets for most Skulls,...
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...
As I found in the last post, the isolated UART bus daisychained through the Tesla modules is running at an odd frequency, 612,500bps. This is problematic as it is not a standard PC baud rate. I had an FTDI board lying around so I had a peek at the datasheet...
Here's an electrical schematic. It really is very simple. I wanted to have another one or two LED rows, but I want separate pwm for each one and the servo library eats up two of my pwm pins. Oh well, four will still look cool.I have been making the various...
