Following the previous log An individual job and all the necessary processing, I wrote the program gold_01.c to check the behaviour before I increase parallelism. First thing it did was confirm that the result C=1 occurs only when the result X=0. So...
Barcode (QR) reader – part 1 Here's another one of my little weekend projects (in this case, more than one weekend). It is a barcode (and QR) reader that plugs into the PC's USB port and is seen by the system as an HID device, specifically a keyboard....
While we were trying to figure out how to display it on a 4x8x32 LED matrix we decided to take a little break and try and wire the speaker to the Arduino board using a resistance. The only issue we had with this was the quality of our speaker. We ordered...
IntroductionThe mini CNC engraving machine laser engraving machine is suit for make non- metal processing such as plastic , wood , acrylic , pvc, pcb, wood or the like material , etc.And airframe adopt profiles + plastic ，small size, light weight...
Dan Maloney12:00 PMOK folks, here we go! I'm Dan, I'll be moderating today along with Dusan as we welcome Quinn Dunki back to the Hack Chat. We had Quinn on a couple of years ago to talk about machining in general, but now we want to get into specifics...
There are plenty of great implementations of different and historically important CPUs available on various FPGA-based platforms, but to my knowledge very few trying to implement calculator CPUs. Old calculators where one of the first examples of "microcontrollers"...
In order to decode the 23 bytes of payload that the sensor is sending we need to implement a decoder, in this case we need to create one custom. Once you select to create a custom decoder you just simply copy and paste the next code which is written...
1 Intro The Enecsys Gateway is a Zigbee gateway allowing communications between the Enecsys microinverters and their monitoring backend. The Enecsys company is unfortunately defunct since 2015 and their DNS domains have been taken over by a UK enecsys...
It is Wednesday my dudes, 15:56, 22/02/2023 Well, let's see if I can get this right this time. I will first try to make that dang equation work, and then I will try to see articles using actual heavy duty McKibben muscles and guess the dimensions...
(Here's the complete description - sorry for some redundancy.) There are many single chip bipolar stepper motor controllers. These can supply one to two amps and work great for most NEMA 17 and smaller motors. But I wanted to control a long NEMA 23 motor...
Really Mike, why a TMD-3? Before I talk about what TMD-3 will be, I would like to give a brief overview of Turing machines, the TMD-1 and TMD-2 designs, and what prompted me to want to do a TMD-3. Turing Machines 101 The Turing machine was invented in...
The story behind this project Every now and then I would find the need for a differential probe. I’d end up using a high voltage diff probe, which you've probably seen lurking around most electronics labs – the ones housed in a large rectangular box...
I bought the 8 Mbit flash P25Q80H-SSH-IT at lcsc.com for $0.10 if you buy 10. First I tried it with this circuit on a breadboard: The numbers are the pin numbers on a Arduino Nano, which runs with 5 V, so I used the resistor dividers for scaling...
Monday, 13:38, 26/12/2022 I didn't had an idea for a Project Log 18 yet, but since I added so many off-topics on Project Log 17, my Hackaday website started to lag and I was afraid of resulting in the same problem/bug that happened in the Project...
