Tiny USB Windows® Key
In this post, you can see a tiny, yet quite useful, microcontroller-based USB key/Foot Pedal for Windows™ computers as a little do-it-yourself project. It is particularly geared as single function key, but other usages are […]
Bicycle Headlamp & Taillight
This article comes with the construction points of a do it yourself bicycle headlamp (white) and taillight (red or amber). The bicycle headlamp-tail light set presented here provides brilliant illumination for all bicycles, and can […]
A Funny Digital Toggle Switch
This time I’d like to share my funny thoughts on the build of a very ‘hobbyist’ digital toggle switch device. The project idea keeps things as simple as they can be. You have a sensor […]
Arduino – Get Better Analog
This is a quick primer on analog signal processing, which lets you smooth out the noise from analog readings in Arduino microcontrollers, resolving one of the major disquiets of analog sensor inputs, very easily. Recently, […]
Arduino Bird Feeder Servo
Feeding birds everyday will go a long way in the conservation of birds. So just remember that by installing a nest box in your garden you are actively participating in bringing about a vast change […]
Arduino High-Power Driver/Switch Guide
The Arduino is an excellent microcontroller you probably already know that. An Arduino board can however only control low-current devices, so often you need a proper driver circuitry to handle the low-current control signals and […]
MCP4725 I2C DAC Module – Quick Entry
For a while now, I’ve had need of a simple digital to analog converter circuit to be able to work with an Arduino microcontroller. To this end, I had a good search around and eventually […]
Philips Astra Spot Review & Teardown
For a long time I’ve been wanting to use elegant spotlights in my workshop, and although I have a few issues to take care of, like a simple model and a way to install it, […]
Coreless Motor Guide
If you’re in a plan to make a minuscule robot, you’ll then need to learn more about a coreless motor. I came across it as a pretty great solution for an upcoming healthcare electronics project. […]
L293D Arduino Motor Driver Shield – A Quick Walk
On COVID-19 lockdown days, I came across several motor driver modules in my scrap box in the attic – surprisingly most of them are unused Chinese modules. The L293 Arduino Motor Driver Shield, in particular, […]
