DIY – How to make 1:150 micro RC Car

I modified the TOMYTEC “THE Car Collection” 1/150 TOYOTA CROWN to work with a remote control. The car is controlled by a self-made infrared remote control.
The remote control format is proprietary.
The battery installed in the car is a lithium polymer battery(3.7V 40mAh).
I used motors by removing weights of the vibration motors.
In order to write the program of the microcontroller(ATtiny1616) used on the car, you need ATMEL STUDIO 7 or later and a device that can use UPDI.
I use MPLAB PICkit 4. AVRISP mkII cannot be used.

Alternative-meat startup is hoping a 3D-printed steak can upend the meat industry

It may look like Play-Doh. But it’s actually a 3D-printed steak.
It’s made by the Israeli alternative-meat startup Redefine Meat, and the technology behind it is one of many contenders in today’s sizzling-hot international race to capitalize on the growing faux-meat market.
Redefine Meat isn’t focusing on alternatives to ground beef or sausages, but whole-cut steaks — an area of the market that has yet to hit the mainstream.

How to fine-tune pfSense 2.4.5 for 1Gbit throughput on APU2/APU3/APU4

Background information

APU2, APU3 and APU4 have four 1Ghz CPU cores, pfSense by default uses only 1 core per connection. This limitation still exists, however, a single-core performance has considerably improved. With new BIOS, and settings described below, pfSense can route about 750-800Mbit/s on one connection.

APU2*4 have very performant Intel I210-AT Network Interfaces. These NICs have 4 transmit and four receive queues, being able to work simultaneously on 4 connections. With some fine0tuning, pfSense can take advantage of this and route at 1Gbit when using more than one connection.
