In this video we will be having a closer look at active rectifiers. For decades we have been using full bridge rectifiers to convert our mains AC voltage into a DC voltage that we can then step down to power all of our electronics devices. But the problem is that a full bridge rectifier consists of 4 diodes that come with a noticeable voltage drop and thus power losses. Because of that an active rectifier uses MOSFETs instead of diodes in order to decrease power losses. Does that makes sense? Let’s find out!
This video is about how to 3D print fabric in a conventional desktop 3D printer. We review the basics of 3D printed fabrics and the different ways of making them, including a step by step tutorial to print your first fabric swatch.
Make your Amiga 500 Mini infinitely better with the A500mini Pandory mod!
Download, then pop it on a usb stick. Easy!
Note: This is a softmod. It does not change anything on the THEA500MINI. To remove it, delete the folder or just don’t use the USB stick.

An overheating CPU can cause the touchscreen to lag and even shut down during driving.
Electric car maker Tesla issued a soft recall for almost 130,000 of its cars because of an overheating issue with its onboard CPU, according to a report by electrek. The overheating can cause the infotainment touchscreen to malfunction. Thankfully this type of recall doesn’t require people to return their car to the dealership, and a fix will be made available via over-the-air software update.
What I wouldn’t have given for this tech back in the 80s. PCBWay.com gave me the opportunity to make this board and sponsored this video.

I challenged myself to port my Ludum Dare 46 entry to as many consoles as I could during the jam’s voting period. It went better than I expected and, by the end, the game was working on the PS Vita, Nintendo DS, Wii, GameCube, and PSP!
I’ve been on Thingiverse for about ten years, and it has served me well. More recently however, there have been a series of problems and other, more developed options have become available. In this video, I explain why I’ve switched my online designs to Printables by Prusa and take you through its advantages and how to use it. This includes easily migrating all of your Things from Thingiverse.
Could this bring Luigi back?
I have converted the 1/87 scale BUSCH Smart Fortwo into the radio controlled model.
The steering is operated by 3.9mm diameter stepper motor and the drive by 4.1mm diameter DC motor.
Wireless communication is performed by two Bluetooth modules(RN4871U).
The RN4871U must be configured for communication before assembly.
The transmitter is built on the breadboard.
The microcontroller used is ATtiny3217 on the transmitter and ATtiny1616 on the receiver(the car side).
Single axis self-balancing reaction wheel inverted pendulum. This thing is inherently unstable and a common challenge in control theory. The mechanical structure is built using only Lego parts. Motor is also Lego. Angle sensor and electronics are not Lego.
