Creating Easy Glass Circuit Boards at Home: Printed circuits boards surround our daily lives : High Tech products, computer tools, household appliance, have one or more electronic circuits. Before in tutorials, I explained the manufacture of a printed circuit…

PCB FOR INTERACTIVE MODULE 8x8: I have previously done a project about "INTERACTIVE RGB LED TABLE" with A2 size, 16x16 RGB LED matrix on foam sheets. I gifted it to my friend. Today, I will share how to implement this project by designing an INTERACTIVE MODULE…

Open Frame Mini ITX PC: I've been wanting to build a small desktop PC for quite some time. I also really liked the idea of an open frame test bench style chassis- something that would allow me to easily remove/replace components.My requirements for hardware…

Daniel Hingston wanted to build a four-legged walking robot for several years, and with current coronavirus restrictions he finally got his chance. His 3D-printed robodog, dubbed “GoodBoy,” is reminiscent of a miniature version of Boston Dynamics’ Spot, which…

Two Sided PCB Using Toner Method: This describes an easy method to make professional looking two-sided printed circuit boards at home.

As a fun weekend project at home, Arnaud Atchimon and his son came up with a DIY laser blaster game comprised of a 3D-printed shooter and target setup.



Both devices are controlled by an Arduino Nano, and when the gun is powered up, you can either have…

How do we know that planets exist outside of our solar system? While too far away to observe directly, with extremely sensitive equipment like the Kepler space telescope it’s possible to detect changes in light as these exoplanets pass in front of a star.…

Er13k was inspired to create an Arduino music box to go along with his girlfriend’s giant stuffed dog Tobias. This eventually morphed into something that not only plays songs on its own speaker, but also lights up a 3D-printed keyboard with LEDs. Perhaps…

One of the simplest ways to make a mobile robot involves differential steering, where two wheels move at different speeds as needed to turn and a ball caster keeps it from tipping over. The MrK_Blockvader is an excellent take on this type of bot — demonstrated…

First the robots took our jobs, then they came for our video games. This dystopian future is brought to you by [Little French Kev] who designed this adorable 3D-printed robot arm to interface with …

When form is as important as function

3D-printed cleaning robot which is based on an fpga. The robot has several sensors to detect obstacles and a suction unit to clean floors. In addition, the robot contains a navigation algorithm that enables it to drive off rooms as efficiently as possible…

If you ever watched the 1980s Inspector Gadget cartoon, you undoubtedly wanted a hat like his, which can pop out all kinds of useful tools under voice control. Although it won’t allow you to fly off after saying “go go gadget 'copter,” DJ Harrigan's replica…

Would you like your own industrial robot arm, but don’t have tens of thousands of dollars to spend? You could instead build Giovanni Lerda’s KAUDA, a five-axis device that uses under 800g of PLA, an Arduino Mega, and other off-the-shelf parts.



KAUDA utilizes…

Pyramid Levitator: Pyramid Levitation System - How it works:The Pyramid Levitator uses two Piezo ultrasonic transmitting speakers pointing towards each other. The opposing beams of 40kHz sound waves create what's called standing waves and pressure nodes.…

Ultracapacitor Powered Robot: Little Flash is a 3d printed robot powered by ultracapacitors. To prevent getting stuck, she uses a bump switch and random path adjustments. She runs for 25 minutes and can be charged in about 40 seconds using a 10 amp constant…
