This instructable explains how to pinpoint the location of an object using an Arduino, two ultrasonic sensors, and Heron’s formula for triangles. There are no moving parts. Heron’s formula allows you to calculate the area of any triangle for which all sides are known. Once you know the area of a triangle, you are then […]
In the mid eighties synths manufaturers started a “less is better” process that led to barebones synths. This allowed the reduction of costs on the manufaturer side, but made the patching process tediuos if not impossible for the final user. Manufacturers themselfs and third party companies realized optional boxes full of knobs and/or sliders to […]
I think this is a topic every parent is struggling with. How much can the kids play with their iPads (or any other tablet). We tried multiple approaches, like fixed times, but that did not really work as our kid then always wanted to go home the moment he was allowed to play with his iPad. […]
This instructable will show how to monitor EC, pH, and temperature of a hydroponics setup and upload the data to IBM’s Watson service.Watson is free to get started with. There are paid plans, but the free plan is more than enough for this project. Step 1: Things You’ll Need Any ESP32 development board. This one seems reasonable, […]
Join me in creating ground effect lighting for my scooter using a bluetooth microcontroller and addressable LED strip. For this project I’m recycling two bits of pixel strip leftover from my old POV bike project tutorial. These are APA102s or DotStars, but you could totally use Neopixels for this project, I just happened to have […]
Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with […]
I made a Sunlight simulating lightbox with a mountain village skyline, that I might upgrade to a wake-up light some time, for a school project. Step 1: Get the Supplies Supplies I used: -Arduino UNO -Neopixel ledstrip 1m, 30 leds(DC5V-W2812) -3 jumper wires -USB cable type B -5V power adapter -Aluminum tape(or aluminum foil) -4mm […]
This interactive wall art piece is approximately 39″ tall and 24″ wide. I laser cut the wood at Clemson University’s Student Makerspace, then I hand-painted all the triangles and installed the lights on the back of it. This instructable will walk through how I made this exact piece, hopefully the concept of it will inspire […]
In this project I will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. And at the end I will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel. Let’s get started! […]
This was my project for Hack Sioux Falls. I built it one weekend and it turned out a lot different than I thought it would. It was a lot of fun and there are a lot of variations on what you could have the Arduino code do once you get the shadowbox wired up. My […]
