Tutorial on the Theory, Design and Characterization of a CMOS Transimpedance Amplifier
https://www.electronics-lab.com/tutorial-on-the-theory-design-and-characterization-of-a-cmos-transimpedance-amplifier/
In this episode, Shahriar and Shayan discuss the design and characterization of a deceptively simple CMOS inverter-based transimpedance amplifier. The the large and small signal behavior of the CMOS inverter is discussed and measured using the Keithley 2450 and 2460 source meters. The transient response is also measured using a Keysight MSO-S series oscilloscope. The […]

Arduino MKR1000 – 32-bit board with WiFi
https://www.electronics-lab.com/arduino-mkr1000-32-bit-board-with-wifi/
The MKR1000 development board from Arduino provides a simple way to add wireless connectivity to IoT battery-powered projects. Arduino MKR1000 is based on the Atmel ATSAMW25 SoC (System on Chip), that is part of the SmartConnect family of Atmel Wireless devices, specifically designed for IoT projects and devices. The ATSAMW25 is composed of three main […]
ATiny does 170×240 VGA with 8 Colors
https://www.electronics-lab.com/atiny-does-170x240-vga-with-8-colors/
AtomicZombie @ avrfreaks.net used an ATtiny85 ATMEL microcontroller to produce a 170×240 VGA signal and also send audio along with video. The original plan was to just bit bang some mono VGA and do up a Pong or Tetris game, but things went MUCH MUCH further than I ever thought possible, so over the next few […]
Raspberry Pi Zero Information Display
https://www.electronics-lab.com/raspberry-pi-zero-internet-connected-information-display/
Frederick @ frederickvandenbosch.be has build an Internet connected OLED display using Raspberry Pi Zero module. After last week’s Pi Zero mod, I thought I’d try a slightly more useful project. Using an Adafruit OLED display, two push buttons, a wifi dongle and a Pi Zero, I made an internet connected information display. The information could be […]
DIY I2C LCD Display
https://www.electronics-lab.com/diy-i2c-lcd-display/
sspence @ instructables.com shows how to interface a character LCD using I2C and only two IO pins. The typical parallel LCD used with an Arduino (16×2 or 20×4) has 16 pins. Only 6 I/O pins are required on the Arduino, but what if you could get that down to two I/O pins, and still have those […]
FUN but REAL: Manually or lying down
https://www.electronics-lab.com/fun-but-real-manually-or-lying-down/
Yes, these are your options when you want to set time relay of 12.51 series from Finder producer. Italian producer accommodated less active installers that can now set, resp. program time relay also lying down. Of course, something for something – you need to have a computer but luckily it is something that almost any […]
