ELECTRIC WHEELCHAIR MAKES A GREAT BASE FOR A BIG ROBOT

Building robots can be fun, and remains a popular pastime among many in the hacker and maker set. However the hardware side of things can be daunting. This is particularly the case for those attempting to build something on a larger scale. A great shortcut is to start with a robust mechanical platform from the outset – and using an electric wheelchair is a great way to do so. [Nikita] started this project w ...

Around the world with Timeline’s Remote Production

In the world of outdoor broadcast, what do you do when you have an event in South Africa one day, and – let’s say – in the UK the next? It would be a logistical nightmare, not to mention expensive, to ship an OB van with all its kit and a whole production crew between locations in such a short space of time. We spoke to broadcast services specialist, Timeline TV, about the innovative remote production solut ...

A DC Motor Controller with Control Leds

It can be controlled through logic levels to set the speed and the direction of the rotation of CC brushed motors and stepper motors; outputs have LEDs indicating the rotation direction. The circuit board we are presenting this time is based on the dual-bridge driver L298N, in a traditionally mounted version in a Multiwatt container with 15 staggered pins; it has two terminal blocks for attaching to DC moto ...

Diodes – Types and Applications

In semiconductor and electronics industry, a diode is a widely used discrete component. It is a significant element in many electronic circuits and applications ranging from low power signal circuits to power rectification. Based on the functions and ratings, there are different types of diodes. However, all semiconductor diodes contain a PN junction to perform their basic operation. Definition of a Diode A ...

MCPCB – FIVE QUESTIONS YOU MUST KNOW

Introduction In recent years LED technology has experienced rapid growth in its adoption and general application. Like any other electronic device, LEDs make use of electricity. However, they generate a rather massive amount of heat that would usually be harmful to the lifetime and integrity of the circuit board within it. Metal Core Printed Circuit Board (MCPCB) Technology is responsible for the ability of ...

Teardown and experiments with a Doppler microwave transceiver

I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler radar module before and was wondering if I this one is any different inside. The C900502 transceiver has a very sturdy metal casing. It is measured at roughly 5cm by 5cm by ...

Easy IoT Weather Station With Multiple Sensors

A weather station is a fun project that teaches you a ton about electronics with the added benefit being an actually useful little device. The project requires a bunch of cheap parts and sensors totaling less than $15, and the whole thing ends up fitting in your hand. The station creates a web site that monitors temperature, dew point, humidity, pressure, light index, and rain (Thingspeak channel). It’s a p ...

MAKING A DIGITAL CLOCK A LITTLE MORE INTUITIVE

Digital clocks are extremely useful and generally considered pretty easy to read. However, they can sometimes have rather arcane interfaces for setting the time and alarms. For [Michael Wessel], he noted that in the 1980s he had to routinely help his grandparents set their clocks for this very reason. That inspired his most recent project – a digital clock that’s intuitive to use. Many digital clocks work i ...
