What would you give for a battery, 5x the storage capacity of whatever you’re reading from? Well, the countdown to commercial availability for batteries of this type of capacity has already begun and it would be considerably cheaper than then currently available batteries. This radical improvement comes from using sulfur cathodes rather than graphite in lithium-ion batteries. Sulfur […]
The REF_XDPS21071_45W1 from Infineon is a 45W USB-PD type C charger reference design in a small form factor. The reference design has been developed to demonstrate the performance by meeting various regulatory limits as well as allowing for small form factor designs. It features Infineon’s digital flyback controller XDPS21071, 700V CoolMOS™ P7 Superjunction MOSFET (IPD70R360P7S), OptiMOS™ PD synchronous-rectification MOSFET

For British kids of a certain age, their first experience of a computer was very likely to have been in front of a Sinclair ZX81. The lesser-known predecessor to the wildly-successful ZX Spectrum, it came in at under £100 and sported a Z80 processor and a whopping 1k of memory. In the long tradition of

STMicroelectronics is making design starts using 8-bit STM8 microcontrollers (MCUs) faster, more affordable, and more accessible for creative minds of all types by introducing new development boards in the easy-to-use Nucleo-32 form factor. The compact boards are controlled and powered conveniently through a USB connection. An ST-LINK debugger/programmer is integrated, which saves using an external

Hearing loss is a common problem for many – especially those who may have attended too many loud concerts in their youth. [mircemk] had recently been for a hearing test, and noticed that the procedure was actually quite straightforward. Armed with this knowledge, he decided to build his own test system and document it for others to
It’s becoming quite obvious that traditional batteries are limiting the progress of IoT devices. They are expensive, they contain harmful chemicals and most importantly All-Batteries-Will-Die. Vemund Kval Bakken chief technology officer and co-founder at ONiO say the real problem with the battery approach to IoT comes when you actually consider the battery shelf life as well as the environmental

When the need for speed overcomes you, thoughts generally don’t turn to 8-bit computers. Sure, an 8-bit machine is fun for retro gameplay and reliving the glory days, and there certainly were some old machines that were notably faster than the others. But raw computing power isn’t really the point of retrocomputing. Or is it?
THIS SNAPPY 8-BIT MICROCOMPUTER BRINGS THE SPEED TO RETROCOMPUTING Continue Reading
Picosun Group, global provider of leading AGILE ALD® (Atomic Layer Deposition) thin film coating solutions, reports record performance of silicon-integrated, three-dimensional deep trench microcapacitors manufactured using its ALD technology. Increasing efficiency and performance demands of portable and wearable electronics, along with their shrinking size in accordance with the Moore’s law, set new challenges to the power
