Electronics Reverse Engineering Walkthrough – Hacking the Monoprice Select Mini 3D Printer

I’d like to design my own custom UI for my Monoprice select mini 3D printer. But before writing some software we obviously need to know our enemy and reverse engineer all the hardware components.
In this video I will go through every single detail in how I reverse engineered the MP Select Mini (or Malyan M200) 3D Printer.

DIY Class D Audio Amplifier

In this project I will show you why a class AB amplifier is pretty inefficient and how a class D amplifier on the other hand improves this efficiency. At the end I will show you how we can apply the theory of operation of a class D amp to a couple of common components in order to create our own DIY class D audio amp.

$2 18650 Li-ion Battery Charger: How to Design and 3D Print | TP4056 module

How to design and 3D print a 18650 Battery Charger for under $2 on an Ender 3 using a TP4056 module In this video I show you how I designed and 3D printed my 18650 battery charger and how I soldered all the wires.
The price of one charger for 4 batterys is under $2.
Price of a charger for 4 batterys: around $2 100 contacts $5
4 pair of contacts 4x $0.1 = $0.4
10 TP4056 $2
4 pieces 4 x $0.2 = $0.8
Some filament less then $1

Raspberry Pi 4 Firmware Updates Tested: A Deep Dive Into Thermal Performance and Optimization

The Raspberry Pi 4 launched earlier this year to critical acclaim, thanks to upgrades including but not limited to a more powerful processor, the first new graphics processor in Raspberry Pi history, true gigabit Ethernet connectivity, and PCI Express-connected USB 3.0 ports.
It also drew some criticism for its higher-than-expected power draw and, correspondingly, heat output — something the engineers at the Raspberry Pi Foundation have been working to address in a series of firmware updates.
