How to use a fully differential amplifier as a level shifter
Loren Siebert @ ti.com discuss about how to interface signals that have a reference voltage that isn't 0V while preserving the DC information. Many signal paths are direct current (DC)-coupled, and this can lead to challenges when different portions of the signal path require...

MemType USB Stick With All Your Passwords
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...

Differential 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...

They’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...

Temperature controlled Fan
Ahmad Al-Shalabi and Bassma Karbouj show us how to control a DC fan using easy to find components. The fan works when temperature reach into pre-specified threshold. The purpose of this project is creating a cooling system by controlling in a DC fan in a simple way without using...

Inverter crystal oscillator
Vasily Ivanenko build some discrete chip oscillators with 74HC series logic gates and tests them on his oscilloscope. He writes: In numerous RF synthesizer chips lies an inverter with input and output pins for making a reference crystal oscillator clock. I built some discrete chip...

A 1.99$ Wifi Module from ITEAD Based on ESP8285 the Killer of ESP8266
Espressif announced ESP8285 a Wi-Fi chip for wearable devices on May,2016. Some described this chip as the killer of ESP8266, that is because ESP8285 includes an embedded 1 MByte flash memory. This means smaller area in PCB is needed to include your Wifi chip while the old ESP8266 needed...
