Satellites are man-made instruments that collect information and data from space. Humans have pioneered space technology over the years and space technology is more accessible than ever. Earlier Satellites used to be very complicated and expensive but Now space technology is more accessible and affordable than ever. Nowadays we can build a satellite quite easily […]
This is an Instructable about a mini oscilloscope I made, it isn’t anywhere near as capable as a real (digital) oscilloscope (such as my Rigol) but I think it is nice to have. Even more important, I enjoy making things, even when they have no real use. For an example of that, just look at
Overview I grew up watching Star Trek: The Next Generation. I’ve always wanted to build a Star Trek themed device, so I finally got around to remixing one of my old projects to make a Star Trek Display Terminal. The terminal provides the following information: Weather – using the National Weather Service Indoor Temperature, Humidity

Gamify your chain reaction by using a Strawbees grabber connected to Makey Makey to start a timer in Scratch when you grab a conductive egg. Drop the egg on the Strawbees roller coaster track. When the egg rolls into the egg drop, it stops the timer. Here is what our full project in action looks
It is a 3D paper heart which starts Blinking (Glowing) when someone holds it. To surprise someone, this gift is a perfect idea as it looks like a simple origami heart but it starts blinking just like a beating heart when someone touches or holds it. This Origami beating heart can be easily made in
Hi there! i have built a climate box to grow mushrooms. It can regulate both temperature and humidity. The heating or cooling works with a peltier element. The air humidity is increased with an ultrasonic nebuliser. I have built everything modular, so that you can also reproduce individual parts. Have fun with the manual Step
When you need pulses of any sort, long, short and with variable frequency you can use one or two 555 timers. That works, is easy to set up and is cheap. But it also limited to a certain range in frequency and pulse length. If you want a precise pulse length you will need an
The Kitronik Inventor’s Kit for the BBC micro:bit is a great introduction to microcontrollers with electronics using a breadboard. This version of the kit is designed for use with the inexpensive BBC micro:bit. The detailed tutorial book which comes with the kit includes MakeCode examples using Blocks and JavaScript equivalent code for the last few projects. This is more suitable

This 3D printed switch will allow the user to turn a Makey Makey into a “finger slide” for a “click” in gaming or could be right/left arrows to scroll through presentations. The addition of right and left terminal mounts for the ground wire makes it flexible to meet the hand dominance needs of the user.
Controlling your computer by using hotkeys and macros is a great way of speeding up your workflow. Unfortunately a device dedicated to doing that (for example Elgato’s Stream Deck) will cost you about $120. That is why I designed FreeTouchDeck. FreeTouchDeck will cost you about $20 (including shipping!) to make. It uses an ESP32 and
