World’s First Petabyte Hard Disk Drive Contains Glass for Better Storage Capacity

Glass is the future of data storage, as proven by Microsoft in 2016 when they showed the world how could the DNA strands be used to store data. It serves as the biological counterpart to the traditional flash- or disk-based storage.

But as Microsoft has tested, they found that glass storage is more practical. Somewhat like the traditional DVD recording media, they also used infrared layers to distort the glass but placed it inside the glass and away from the open air. According to Microsoft, the data recorded is read by lasers and decoded by the machine learning as light reflects off the glass.

New Xeon-capable motherboard offers 20 USB 3.2 ports

Industrial PC company Portwell is offering an unusual server motherboard. The PEB-9783G2AR is a FlexATX board designed for use in low-profile chassis, supporting Intel Comet Lake-S CPUs and up to 128GiB of DDR4 ECC RAM. This, and the rest of the board’s specs, are pretty normal—but then there’s the 20 USB 3.2 type-A ports.

Building a USB Type-C PD Powerbank the Super Simple Way || Testing an Aliexpress PCB!

In this small project I will show you how to create a DIY USB Type-C PD powerbank the super simple way. To do that I will firstly test a powerbank PCB based around the IP5328P IC I got from Aliexpress. The measurements will show us how suitable the PCB is for creating a DIY powerbank. Afterwards I will then show you how I created a Li-Ion battery pack and a custom 3D printed enclosure before I will put all the components together to form the powerbank. Let’s get started!

Soldering basics and choosing a cheap soldering iron.

The soldering equipment on eBay is actually very usable. I test a cheap generic 936 soldering station in this video, including a look inside the unit and at the PCB, and exploration of the actual iron.
One of the nicest things about these soldering stations is the ready availability of cheap parts from the internal PCBs to the complete irons and a wide selection of tips/bits.
