This vintage mini TV is mimicking a CRT TV but inside hidden is a UV laser projecting on a glowing 3D printing material. It's a fun 3D printing weekend project to explore simple physics.

![Programming the new ATtiny from Arduino using UPDI [Beginner Tutorial]](https://i.ytimg.com/vi/AL9vK_xMt4E/mqdefault.jpg "Programming the new ATtiny from Arduino using UPDI [Beginner Tutorial]
This tutorial shows how to make a cheap and simple UPDI Programmer and upload a sketch to the new ATtiny micro controller series. The programmer is made from an old Arduino Nano and requires only two additional passive components. The megaTinyCore library provides an Arduino core to start developing. A short blink sketch demonstration should provide a good start for every beginner in this matter.
Links to the github projects:

!!! This method stopped working with the latest megaTinyCore versions. Installing v.1.x like in this video works though. good luck!

![CRT BOY: The Circuit [ESP32, CRT, Retro]](https://i.ytimg.com/vi/ARo205bYEfI/mqdefault.jpg "CRT BOY: The Circuit [ESP32, CRT, Retro]
This is the first part of the project building a retro GAME BOY clone. An old school mini CRT is used to display the video signal generated by the ESP32 micro controller. An NES game pad is connected to be able to play games. A simple Tetris clone from a previous project is used to test the device. This part covers the building of the circuit including a simple audio amplifier.
