The STRENGTH of 3D prints REMELTED in SALT

Everyone is currently talking about 3D prints remelted in salt, but how strong are they really? I printed parts in DasFilament PLA, ESUN PLA+, DasFilament PETG and ESUN ABS, and remelted them in salt. I’ve also been looking at different salt grain sizes and the temperatures that are necessary to properly re-melt the parts. Let’s find out, if we can get 3D prints with the strength of injection molded parts!

DeLorean Electric Car Conversion: Behind The Build

A lot has changed since Back To The Future was released in 1985. During these last 3.5 decades, we’ve seen a plethora of hybrid and electric cars enter the market – from the practical Toyota Prius to the industry disrupting Tesla. The EV revolution has also inadvertently led to a new era in DIY electric cars. With more electric cars on the road, Motors, inverters and battery cells, which used to be hard to come by, are now readily available on the after market.

John DeLorean’s DMC-12 – the car we all know and love as Doc and Marty’s Back to the Future Car was meant to be the definitive sports car of the 1980’s. The gull-wing doors and stainless steel exterior made it a unique curiosity for car enthusiasts. However, there was one big problem with the DMC-12, its small 6 cylinder engine put out a feeble 130 hp. But for one special DeLorean, a Buick Grand National Engine swap created, what was referred to as, the world’s fastest DeLorean. The turbocharged 4.3 liter v6 was tuned to 570 horsepower.

Hey LEGO, I Fixed Your NES! – I Built A LEGO NES That Really Works!

I Built a LEGO NES That Actually Works! I bought the Lego Nintendo Entertainment System set to build on camera. It took quite a while to build but looked pretty cool when I was done… but it’s just a Lego set so I doesn’t actually play games. So I decided to fix that by building my own version which will fit original NES games and actually play those games.

DIY Android+Arduino Controlled Labyrinth (Maze) Game

The device presented in the video represents marble maze game that is controlled using a smartphone via Bluetooth connection.

The device consists of two parts. The first is the Arduino part where the servo motors are controlled and the second part where the signals generated by the accelerometer are sent via the Android smartphone. It consist few components:

– Arduino Nano microcontroller

– Bluetooth adapter

– and two 9g servo motors

How to Make a WiFi Repeater using ESP32 NodeMCU | WiFi Router Range Extender ESP8266

In today’s video we look at how to extend the range of an existing WiFi network by repeating the signal. This extension will be done using an ESP32 NodeMCU. This process also works for ESP32 only.

ESP32 as WiFi NAT router. It can be used as — Simple range extender for an existing WiFi network — Setting up an additional WiFi network with different SSID/password for guests or IOT devices.
