mini CNC project[300×300mm] based on 2020 / 4020 - alum. X-profiles

EN
That is my “redesigned” idea of mini CNC router. All parts where ordered from Aliexpress or Ebay and it was not so much as cost actually.
The project took few months to assemble and to get all parts. The result is quite average but not that bad.
Axis movement is smooth with that rollers, but not very strong in that setup. If you wish to have stronger base, then your design must be with only big V-wheels, made from strong ABS plastic and maybe few of them on each side as the developer from OPEN BUILD make.

Atmel ATTiny85 and mini OLED 128*32px i2c how to..

EN

Welcome!
Have you been searching in internet for that particular combination of OLED screen and controller? Yeah, me too.
And I found some solution that work good for me, and if you like to test it hopefully do the same for you.
Before starting my write up, will kindly suggest you to get the following:

TinyWireM - I2C library , best for Attiny85
You can downloaded it here: http://github.com/adafruit/TinyWireM

Tiny4kOLED - one really good I2C OLED library, dedicated to 128*32 - SSD1306 module
You can downloaded it here: https://github.com/datacute/Tiny4kOLED

LCD Image Converter - that is the best converting ALL IN ONE software
I`ve ever found. And will do most of the work for you. All credits goes to it the developer.
You can downloaded it here: https://www.riuson.c … /lcd-image-converter

IMPORTANT:
- inside the file: Tiny4kOLED.h (from Tiny4kOLED library folder) , find that: #include “Tiny4kOLED_TinyWireM.h” It should be unmarked, and all other with “//” in front
- ATTINY85 SDA/SCL pins are : SDA= D0 (pin5) / SCL=D2(pin7)

Bluetooth GPS sender

EN

Here is the story: I use my cellphone as GPS navigation unit most of the time in my car and unfortunately it GPS chip do not get so fast satellite coverage, or either I need to turn on the 4G network on for fast location.
As “bonus” the back of the phone get hot. Also, sometimes due the navigation process and heat from the car vents phone get fast hot and start loose control.
Next, I try to use my old Nokia LD4W Bluetooth unit and via right GPS sender app my android phone start to work better.
After that, seems become dependent of the battery of that Nokia unit so I bought few parts and create “proper” car GPS sender.
