Novel programming interfaces for MCUs might catch us by surprise, but then we inevitably get up to speed with the changes required. Today’s bastion is HVTPI – a “12V reset” addition to the TPI we’ve just started getting used to, and [Sam Ettinger] has shared a simple circuit to teach us all about it, along with PCB […]

LED and LCD displays are a technological marvel. They’ve brought the price of televisions and monitors down to unheard-of levels since the days of CRTs, but this upside arguably comes with an aesthetic cost. When everything is covered in bland computer screens, the world tends to look a lot more monotonous. Not so several decades

Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks. Today, [Raphael (@rbaron_)] is here to teach us (Twitter, unrolled) what it takes to build a soil-embedded sensor that can actually survive contact with a plant. As the picture might hint, waterproofing is of

Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as follows: Dual sine wave output, synchronized Frequency, Amplitude, and Phase control Low harmonics under 1 MHz Scriptable via Python The heart of the

Often used to make rugs, tufting is a process wherein a hollow needle is used to cram thread or yarn into fabric in some kind of pattern. This can be done by hand, with a gun, or with big machines. Some machines are set up to punch the same pattern quickly over and over again,

[Mr Innovative] decided to make his version of a small pen plotter (video after the break) to make labels on masking tape. The result is an impressive compact machine that is remotely controlled using your smartphone. The plotter is constructed using several different techniques, a piece of plywood as the base, a 3D printed bracket for the

Arduino enthusiast Roni Bandini has created an interesting project investigating is it possible to train a small device with artificial intelligence in order to detect harmful gases? In this machine learning project an Arduino microcontroller was used together with a multi gas sensor and Edge Impulse are used to achieve the goal. Detects harmful gases “Experiencing a chemical

Sometimes you need a little utility device to do a very simple job, and do it well.This one-shot IR helper from [Gregory Sanders] is just that. [Gregory] had a TV that didn’t support automatically turning on when the power was applied. This is frustrating when you like to leave devices switched hard off when not in
ONE SHOT IR HELPER IS A GREAT BEGINNER PROJECT Continue Reading
