This is a completed project.The HX711 has all of the necessary components to process the output of a velocity sensor: 24-bit resolution with nominal sample rates of either 80Hz or 10Hz, a programmable gain pre-amplifier with gain values of 32, 64 and...
Feature List Provide a stable powersupply with short time UPS functionBackup short power interruptions 1 million switching cycles recoded in the eePROM. DC Specification (For best performance use the official raspberry pi USB-C power supply) Input Voltage5V...
The general plan and choices made beforehandThe most important property of an FPV video feed is latency. When the latency of the video is too high, the plane becomes uncontrollable. Half a second is a lot of latency. Latency originates from multiple...
DataThe first step was to get the solar data from my Growatt 3000MTL inverter online into pvoutput.org, which is a great tool for uploading and comparing PV data. The method for getting the data into pvoutput is beyond the scope of this project (but...
First preview :) There nothing, just display and buttons ;) Display configuration sudo apt-get install cmake cd ~ git clone https://github.com/juj/fbcp-ili9341.git cd fbcp-ili9341 mkdir build cd build cd fbcp-ili9341/build rm -r * cmake -DST7789VW=ON...
I wanted to challenge the long range shooting communities to the idea of making their own smart devices to help advance the hobby. I had brainstormed for a while hoping to build up a thermal scope that would be much more affordable than the standard...
Hardware to buyAlmost all of the hardware for the Pyball is available off the shelf at Adafruit. Feel free to shop around though; these are generic items and you might find better prices at Amazon or one of the big-time suppliers like Mouser, Digi-Key,...
When I say "anomaly detection" you may imagine an overly complicated process, something exclusive to deep learning algorithms and indecipherable coding. In reality, the concept of uncovering anomalous behavior in a system is really just the act of identifying...
M10CUBE (M10 in short) road map This is a teamwork project! It is up to the contributors choice to show their name in public Soon... A PLC software using all M10CUBE I/Os : First PLC software will be CODESYS (Raspberry Pi runtime is free...
## BOM Other than the 3d printed parts (all FDM parts printed in black PETG, all Resin printed in Elegoo ABS-like clear-red) the following was used: ### Base- Raspberry Pi 4 (+SD card)- Corsair K65 RGB 60% mechanical keyboard (don't get too attached...
Two separate and identical elements are used which consist of a stepper motor driven spiral, magnetic vertical slider and steel ball bearing. The ball is attracted to the magnet on the slider and the pair are lifted by the spiral as it rotates with the...
If you need a very-high throughput or a multithreaded web server to host data for everyone on the web, look at Apache (with CGI), NGINX or https://www.gnu.org/software/libmicrohttpd/ However they are limited by the CGI's basic inability to preserve a...
Here is the basic hardware I have landed on: Raspberry PI - Use a zero for low power consumption, assuming it can process the audio Audio ADC - TI's tlv320adc6140 is used in the Amazon Echo and other continuous listening devices. Its based on a...
PROBLEM : Many industrial applications involve checking for flaws in places where worker cannot act due to immense heat, toxic gases & limited space. Hence it is essential to monitor such parameters in high value engineering sectors such as electrical...
What It Is and What It's Not (Updated) Since the DEC VT100 was the gold standard for serial terminals in the early years, that's what I will base my design on, and since it will be a driver for a 2:3 scale PDP-8I I'll scale my design accordingly....
