💻 heatshrink: An Embedded Data Compression Library
In embedded systems, space is always tight. Adding pennies of extra storage can be enough to kill a budget (when multiplied by hundreds of thousands or even millions of units), so available space has to be used effectively.
Heatshrink is an open-source data compression library designed for resources-constrained embedded systems that works with as little as 50 bytes of RAM.
The library is written in C language and has the following key features:
▫️ Low memory usage – As low as 50 bytes with specific parameters, and usually under 300 bytes are needed.
▫️ Incremental, bounded CPU use – Input data is processed in tiny bites.
▫️ Static or dynamic memory allocation.
▫️ Released under an ISC license which allows you to use the library freely, even in commercial products.

🤖 KAUDA - Open-Source 3D-printable Robotic Arm
KAUDA is a printable and DIY robotic arm developed with the aim of creating a robot that could cover the functions you want at a low cost, without losing quality and efficiency. Developed by a maker for makers, for those who want to work on it, apply changes, study new functions and therefore have fun with it.
The KAUDA is a five-axis arm with a gripping tool and has a completely open-source set of schematics so it can be printed on any 3D printer. The robot arm uses three stepper motors and two servo motors, and is based on the Arduino MEGA 2560 for control.

📃 Top 5 PCB Design Guidelines Every PCB Designer Needs to Know
Guidelines that you need to know to design your next manufacturable, functional, and reliable PCB.
▫️ Fine-Tuning Your Component Placement: Be sure to orient similar components in the same direction as this will help with effective routing in PCB design. Avoid placing components on the solder side of a board that would rest behind plated through-hole components.
▫️ Placing Your Power, Ground & Signal Traces: It’s always recommended to have your power and ground planes internal to your printed circuit board, while also being symmetrical and centered. This will help to prevent your board from bending, which will also affect whether your components are properly positioned.
▫️ Keeping Things Separate: Be sure to keep the power ground and control ground separate for each power supply stage. To reduce capacitive coupling due to the placement of a large ground plane, try to have your analog ground crossed only by analog lines.

📰 New Optical Switch up to 1000x Faster Than Transistors
“Optical accelerator” devices could one day soon turbocharge tailored applications
A new optical switch is, at 1 trillion operations per second, between 100 and 1,000 times faster than today's leading commercial electronic transistors, research that may one day help lead to a new generation of computers based on light instead of electricity.
Optical computers that replace conventional transistors with optical switches could theoretically operate more quickly than regular computers, as photons travel at the speed of light, while electrons, typically, don’t.
The new device not only can operate extraordinarily quickly, but it can switch using as little as one photon of input on average. In contrast, transistors generally needs dozens of times more energy to switch, while those that switch using single electrons are much slower.
