Week 1 & 2 - PCB Layouts
Log from 25in24 Electronics Project Board
I've started by laying out the five boards in Eagle 9.52. Boards are now being ordered through JLC. All parts have been ordered through Mouser and Digikey - however sourcing a small meter and solar panel that will match have been a bit of...

Week 3 part 2 - testing
Log from 25in24 Electronics Project Board
Well, initial testing was more difficult than expected - took about five hours just to get a couple of basic circuits working. Made a number of incorrect assumptions / mistakes including:Assuming it might be differences between components (germanium...

Rev1 Preliminary Accuracy and Precision Test
Log from Multimeter
As the title says, this is a preliminary test of the first version of the multimeter. Before the test, I basically calibrated it using my Fluke 101 as a reference. The results of the test are as follows: 2.5V Error: 0.569, Coeff of Var: 0.0102 5V Error:...

Rev1 Display Bodge
Log from Multimeter
To make the display work on revision 1, I bypassed the display driver and wired the pico IO pins strait to the segment LEDs. It is a little faint, as the display driver circuit worked completely differently, but it works to test the display.

Rev1 Voltage Test
Log from Multimeter
I did another test with the rev1 prototype, this time only measuring voltage, and bringing it all the way to the maximum voltage of 60V. Again I am doing calibration and comparison to my Fluke 101 Multimeter. This has a problem as the Fluke 101 does...

Prerequisites and software
Log from VGA videocard for microcontrollers
Sometimes, when making your own devices on microcontrollers, there is a need to display huge amounts of information on a display and to use a bigger screen for ease of perception. Unfortunately, there are no ready-made and budget-friendly solutions for...

From prototype to product creation
Log from VGA videocard for microcontrollers
First of all, you should pay attention to the ROM used. The flash-ROM chip from an old computer motherboard has a finicky parallel interface where the address is written in two runs. This complicates the operating logic and increases access time. Additionally,...

Step 1:hardware
Log from Weather Station With A7670 -- Remote Monitoring
Insert the SIM card into the slot on the back of the boardConnect 0.96 OLED to Maduino Zero 4G LTE(CAT1 A7670) 's SCL and SDA;Connect Temperature and humidity sensor's data pin to Maduino Zero 4G LTE(CAT1 A7670) 's D6;Connect Photosensitive...

Step 2: Firmware about sensor
Log from Weather Station With A7670 -- Remote Monitoring
At first, we need to prepare the environment for ESP32 development board programming in arduino, and you can cheak this guide.This is a library for our Monochrome OLEDs based on SSD1306 drivers. #include This library allows you to communicate with...

Step 4: Firmware about LTE
Log from Weather Station With A7670 -- Remote Monitoring
Using HTTP(S) AT Commands, accessing to HTTP server,SerialUSB.println("Maduino Zero 4G LTE CAT1 Test Start!"); SerialUSB.println("Wait a few minutes for 4G star"); delay(3000); sendData("AT", 1000, DEBUG); delay(5000); sendData("AT+CICCID", 1000, DEBUG);...

Schematic
Log from "Perpetual" Wristwatch
It's have simple schematic, for save pins I used Charlieplexing(35 components in total): https://en.wikipedia.org/wiki/CharlieplexingIn this project i use for charging 12 light sensor BPW34S, on clear sun one cell make 0.5-0.6 V and ~2 mA, connect its...

basic protocol structure
Log from VEVOR diesel heater protocol
Some days ago a friend told me about the heaters from Vevor and after some search I found this page very promising: http://afterburner.mrjones.id.au/ So I hoped the Vevor ones have the same protocol structure and things would be quite easy....

What is an egg?
Log from Wobble
Starting project by learning more about eggs.. I'd like to figure out how to create a nice 3D printed egg shape that can hold a circuit board, battery, and motor assembly. I'll start by printing off some free variants from thingiverse. Ultimately I want...

Egg #1
Log from Wobble
I used this great tutorial to make a threaded egg in Fusion360. I made mine about 5 inches around with an egg-shaped volume inside rather than the cylindrical volume in the video. The 50% scaled test print turned out great and looks like an egg....

Hello world
Log from Workshop Automation
Obligatory title. This project has already been underway for months and will likely continue to evolve for as long as I can. Since my workshop is in my basement with no windows, I wanted a way to keep an eye on the outside world. I don't...
