Build an Arduino boost converter
https://www.electronics-lab.com/build-battery-boost-power-supply/
Lucas Reed has a tutorial on how to build a boost converter using an Arduino. Have you ever needed to power a project that’s not near an outlet? Have you needed to test using different voltages? Are you curious about analog circuits and power? Using Autodesk Circuits and a lead-acid battery, you can create a […]
USB to RS485 converter
https://www.electronics-lab.com/usb-rs485-converter/
Marko Pavlin has published a USB to RS485 converter. He writes: Testing of sensors with RS485 using PC without proper interface is not possible. Since RS232 interfaces are very rare, the interface should be hooked to USB. The interface between USB and RS485 can be soldered with one of the many FTDI interfaces with added […]

Jesus Echavarria has posted a new project, a dual USB – Serial and I2C converter to communicate with serial and I2C devices. Hi all! After a couple of months with a lot of work, I come here again with the last board I develop before Christmas. It’s a dual USB serial and I2C converter based […]
Isolated USB-to-UART converter
https://www.electronics-lab.com/isolated-usb-to-uart-converter/
Jacob Beningo shows how to build an isolated USB to UART converter using Sparkfun’s modules. A simple isolation circuit that costs only a few dollars could have been used to protect the USB port on the computer. Embedded system developers get used to plugging strange hardware and components into their computers on a daily basis […]
LT8714 – 80V/5A synchronous 4-quadrant DC/DC controller
https://www.electronics-lab.com/lt8714-80v5a-synchronous-4-quadrant-dcdc-controller/
Linear Technology Corporation announces the LT8714, an 80V input synchronous PWM four quadrant output DC/DC controller. This device cleanly transitions the output voltage through zero volts with up to 5A sourcing and sinking current capability, regardless of the output voltage polarity, making it ideal for regulating to positive, negative, or zero volts. The bipolar output […]

NE555 timer sparks low-cost voltage-to-frequency converter
https://www.electronics-lab.com/ne555-timer-sparks-low-cost-voltage-to-frequency-converter/
by Gyula Dioszegi @ edn.com: In 1971, Signetics—later Philips—introduced the NE555 timer, and manufacturers are still producing more than 1 billion of them a year. By adding a few components to the NE555, you can build a simple voltage-to-frequency converter for less than 50 cents. The circuit contains a Miller integrator based on a TL071 along […]
