LT8335 – Converter minimizes quiescent current
Outfitted with a 2-A, 28-V power switch, the LT8335 2-MHz step-up DC/DC converter from Linear Technology operates from an input of 3 V to 25 V, suitable for applications with input sources ranging from a single-cell lithium-ion battery to automotive inputs. The LT®8335 is a current...

Noela and Miguel from Area0x33 made a really helpful tool on hackaday.io. They designed a fully open source hardware USB stick to store your username/password pairs on. MemType uses Atmel ATtiny85 MCU and V-USB to do the communication over USB. V-USB is software-only implementation...
Continue ReadingDifferential Pair Routing and Meander Tool in Eagle CAD
When you see some board designs, especially ones with high speed signals or differential pair signals, then you will notice a lot of zigzag/meander lines on PCB. If you’re wondering whether you can do differential pair routing, then the answer is simply yes by using Meander...
Continue ReadingThey’re ‘Not’ JUST Capacitors
James Lewis from Kemet has made a presentation to address some of misconceptions about capacitors like how you should de-rate capacitors. James said that de-rating depends on the chemistry and configuration of a particularly capacitor. So he started by asking a question: Should...
