What’s better in the morning than a hot cup of tea?You should keep to the brewing time so that the tea tastes the way you want it to. Unfortunately, there’s always a lot to do and the timer beeps when you’re somewhere else. So we need an automatic “tea extraction machine”….. As always, there are […]
Today, I would like to share how to build a 3 axis CNC machine at home using available or discarded materials. Specifically in this project, I reused 2 old DC servo motors and 2 wooden wine boxes, as well as, taking advantage of my daughter’s unused school supplies. Step 1: Supplies The main materials are
Measuring air quality at any particular location isn’t too complicated. Just a sensor or two and a small microcontroller is generally all that’s needed. Predicting the upcoming air quality is a little more complicated, though, since so many factors determine how safe it will be to breathe the air outside. Luckily, though, we don’t need
This sketch provides a pinball machine controller as an extended example of a real-time logic controller utilizing third-party hardware drivers. It is configured to use hardware in the PinballShield circuit board. This sketch assumes you have already installed several third-party Arduino libraries in your IDE as described in the section Arduino Libraries. All other sketch files
Counting change is a great way to teach children about mathematics and money, but it grows tiresome for those of us that have passed the first grade. Thus, a machine should the job, as [Daniele Tartaglia] demonstrates. A vibrating motor is used to shake a hopper full of coins, letting them fall through a feeder slot
Neoden USA, a distributor of Neoden products in the US, is pleased to announce the launch of their new desktop reflow oven, Neoden IN6. The reflow oven is equipped with 6 heating zones, 3 of them are located at the top and the other 3 are located at the bottom. The multiple zones will provide a superior

The concept of vending machines in hackerspaces is nothing new, but [iooner] took it a step further – as hackers ought to. Putting HDDs into the rotating spring of a repurposed vending machine, right where you’d expect to see a Granola bar, isn’t revolutionary – but we don’t remember anybody doing it before this. And, with how
HDD VENDING MACHINE WORKS LIKE A VENDING MACHINE SHOULD Continue Reading
Branding can be done on wood with just about any old bit of hot metal, but if you want to do it well, properly-crafted tooling will go a long way. [Wesley Treat] has built just that with this modular branding iron design. The branding tooling itself is machined out of brass on an X-Carve CNC router,

An Egg plotter is an art robot that can draw on spherical shaped objects such as eggs. You could also use this machine to draw on ping pong balls and golf balls. You can use your imagination with the designs you put on it, you could for example make personalized eggs for Easter. In this
Restoring vintage computers is the favorite task of many hardware hackers. Retrocomputing probably makes you think of home computer brands like Commodore, Amiga, or Apple but [Erik Baigar] is deeply into collecting early military computers from the UK-based Elliott company. Earlier this year he made a detailed video that shows how he successfully brought an Elliott
