I always wanted to make a PCB and this is my first professional circuit board attempt. So before you decide to start this project you should know there could be some mistakes or it could be more reliable and compact. This design is not the most efficient and cheapest way to make a DIY MPPT […]

Have you ever tried to play a game only to find out you don’t have any dice? That’s not a problem anymore! Now you can create your very own digital dice using LEDs and your Arduino board. This is a beginner-level project. This project will allow you to push a button and randomly generate a […]

In this tutorial we are going to show you how to make an interactive sound wave print within a picture frame, so you can see and hear your favourite song at the same time! When you touch the print through the glass of the frame, it will play the song shown in the sound wave […]

Always wanted to have a graphical weather station? And with accurate sensors? Maybe this project is something for you. With this weather station you can see what the weather is “doing”. Temperatures for example might rise or fall. From a normal thermometer it is not possible to see the temperature history. With this weather station […]

Hi! My name’s Jack and I’m a senior at Boston College studying Computer Science and Finance. This semester, I’m taking Physical Computing with Professor Gallaugher. We’ve been following a flipped classroom model and I made this project utilizing Professor Gallaugher’s Circuit Python YouTube tutorials. For my Campus School Assistive Tech Project, I made a realistic-looking touch-enabled […]

Lumileds has added news LEDs to its Luxeon IR Domed Line with a significant increase in both DC and pulse drive current–up to 1.5A and 5.0A, respectively. The new emitters deliver radiant power of 1350mW at 850nm wavelength (slightly visible) or 1450mW at 940nm (invisible or covert IR). These new IR LEDs are engineered to […]

Hey, what’s up, everyone? So here’s something useful: a custom breakout board for using the ESPWROOM02U module for tinkering and testing. The ESP-WROOM-02U Breakout Board is an ESP8266EX-based microcontroller that offers the same features as its predecessor, the ESP Series, but is way smaller, making it suitable for implementing into a badge or wearable project. […]

The world continues to be dominated by freelancers, meaning you have a great chance of becoming a successful freelance accountant. Whether you choose to do this in your spare time or become a full-time freelancer, marketing is the key to finding and retaining clients. Many small businesses cannot afford an in-house accountant, which is where […]

If you’ve ever looked at prices for prosthetic hand, you may have noticed that they can cost upwards of $5000, with more advanced myoelectric controlled arms priced at over $20,000. Such prices are not ideal considering that over 80 percent of amputees are from developing countries where access to prosthetic limbs is limited by lack […]

My garage door comes with a motor and a 433MHz remote that I don’t always carry with me because it is quite bulky and in the way. Because of that, sometimes when I am in front of it and I want to open it, I had to go inside and press the trigger switch that […]
