KNITTING MACHINE REBUILD TAKES IT TO THE NEXT LEVEL

Those of us who to textile work may own a sewing machine and even if we’re really into it and have the funds, an overlocker. But there’s another machine in that field that few of us will have, and that’s a knitting machine. These machines have a sliding carriage over a long array of needles, and even the cheaper ones are way more expensive than for example a pretty decent oscilloscope. [Irene Wolf] has a Pa ...

USELESS MACHINE FOR AN EXISTENTIAL QUANDARY

There’s no project that dives into existential quandaries more than a useless machine, as they can truly illustrate the futility of existence by turning themselves off once they have been powered on. Typically this is done with a simple switch, but for something that can truly put the lights out, and then re-illuminate them, [James]’s latest project is a useless machine that performs this exercise with a ca ...

RESISTORS SORTER MEASURES VALUES

We’ve all been there. A big bag of resistors all mixed up. Maybe you bought them cheap. Maybe your neatly organized drawers spilled. Of course, you can excruciatingly read the color codes one by one. Or use a meter. But either way, it is a tedious job. [Ishann’s] solution was to build an automatic sorter that directly measures the value using a voltage divider, rather than rely on machine vision as is often ...

PINBALL MACHINE NEEDS NO WIZARD

Ever since he was a young boy, [Tyler] has played the silver ball. And like us, he’s had a lifelong fascination with the intricate electromechanical beasts that surround them. In his recently-completed senior year of college, [Tyler] assembled a mechatronics dream team of [Kevin, Cody, and Omar] to help turn those visions into self-playing pinball reality. You can indeed play the machine manually, and the A ...

OPEN SOURCE PICK AND PLACE HAS A $450 BOM COST

Give your grizzled and cramped hands a break from stuffing boards with surface mount components. This is the job of pick and place machine, and over the years these tools of the trade for Printed Circuit Board Assembly (PCBA) have gotten closer to reality for the home shop; with some models diving below the $10,000 mark. But if you’re not doing it professionally, those are still unobtanium. The cost of this ...

ESPRESSO MACHINE NOW POWERS PLANTS

This thing has what plants crave! No, not electrolytes exactly — just water, light, and moisture polling every 30 minutes. We think it’s fitting to take something that once manufactured liquid liveliness for humans and turn it into a smart garden that does the same thing for plants. So let’s just get this out of the way: the espresso machine was abandoned because it was leaking water from a gasket. [The Pla ...

AN ARDUINO-BASED FLUTE PLAYING MACHINE

It’s one thing to be able to transcribe music from a flute, and it’s another to be able to make a flute play pre-written music. The latter is what [Abhilash Patel] decided to pursue in the flute player machine, an Arduino-based project that uses an air flow mechanism and PVC pipes to control the notes produced by a makeshift flute. It’s currently able to play 17 notes, just over two octaves starting from th ...

Distinguish Walking and Running Using Machine Learning

Electronic market is full of devices called pedometer and fitness tracker. They counts the number of steps you have taken, distance you have covered, whether you are walking or running and bunch of other stuff. Ever wondered, how these devices perform such measurements. I decided to make one on my own and share the knowledge of making it with guys. In this instructable we will develop accelerometer data acc ...
