A while back, we constructed a pair of LED skateboard truck-risers. That project was intentionally created without the aid of advanced tools and techniques. We decided to try the concept again but without limiting ourselves. This time around we used custom designed PCBs and 3D printed parts. There was no limiting ourselves to hand tools and

This project uses green surface-mount LED’s along with an AVR ATTiny45 microcontroller to simulate the behavior of fireflies in a jar. (note: the firefly behavior in this video has been greatly sped up in order to be easier to represent in a short film. The default behavior has significantly more variance in its brightness and

Welcome to my version of the LED reactive table! I was inspired by previous work using discrete LEDs, such as this one, but I figured it would be easier and more fun to use NeoPixels — programmable RGB LEDs that can be set to any color you want. The table consists of a large array of infrared emitters

Designing hardware logic circuits can be fun. The old school way to do this was with NAND gates, on a bread board, wired up with jumper wires. This is still possible, but it doesn’t take much before the number of gates gets out of hand. A newer option is to use an FPGA (Field Programmable

I don’t have to introduce your colleague, Richard. He is The Backbone of the society. Hard worker, everyone knows he is busy all day. He gets all the praise. But you know the truth. And only you. He is hardly working. All he does is roam around with a folder with empty sheets of papers.

This tutorial shows how to move two stepper motors so they will synchronously arrive at defined destination point. There are many sophisticated solutions for doing this such as GRBL or Marlin. Using an Arduino, there are also dedicated “Multi Stepper” libraries that can support you. However, we will use a more basic approach here making it as easy as possible

Since getting an Arduino starter kit I was wondering what to make of all those fancy buttons, shiny LEDs, touchscreen LCD displays… I was thinking about weather station, but I was told that in the maker’s world, weather station is like a “Hello World” app. Like playing “Stairway to Heaven” in a guitar store. Then, when

Tic Tac Toe is a two player game in which the players compete to get 3 pieces in a row. In this project we constructed a Tic Tac Toe game using a number pad and neo pixels as pieces. This results in a portable Tic Tac Toe game requiring only a wall outlet to play.

This is a little diorama made with Arduino for a school project. What happens is a party which just stops playing music. As the sound stops there’s a bright light which turns on. There are two partypeople. One is having a stroke or something because of the alcohol. The other one thinks ‘Dam’n, the party
Party’s Over! Continue Reading
Exactly a year ago (February 2020), James’ wife wanted to expand her plant growing setup in the house. This included a bigger, larger, taller plant growing area AND the need for more lighting. BINGO! The seed for the Idea was planted. After an exhaustive market research, not able to find the product that we had
