Leadscrew Buddy upgrade for 70 year old lathe

My lathe is quite old. It is a Myford M type. This design was originally manufactured by British company Drummond until Myford took over manufacture in 1941.The manufacturer’s plate of my lathe has 1949 stamped on it.
It’s a pretty basic lathe, but it fits into the very limited space I have in my garage workshop. Recently I needed to use power feed on the lead screw, which is when I realised it could do with a modern upgrade.

As with most low tech lathes, the lead screw is driven from the spindle via a set of gears, and by changing these the feed speed can be set. On my lathe the gears are proper 1940s metal things, and the gear assembly involves interlocking them with pins and adjusting two mounts that can be swivelled to allow for the differing diameters.

Tachometer (RPM Meter) || DIY or Buy || How a 3€ sensor outdoes a 29€ product!

In this episode of DIY or Buy we will be having a closer look at a commercial tachometer (RPM Meter) and test it in order to find out that it is pretty much unusable. Afterwards I will show you how a 3€ IR distance sensor works and how we can use it to build a proper DIY tachometer that functions properly. Let’s get started!

A 3D-Printed SCARA Robot Arm That Won’t Break the Bank

In the world of industrial robots, six-axis models are perhaps what comes to mind. However, SCARA – Selective Compliance Assembly/Articulated Robot Arms – are also quite common, for applications where complicated 3D orientation isn’t needed. While these machines can cost many thousands of dollars, and are normally refined over years of work, YouTuber How To Mechatronics created a version of his own using four NEMA 17 motors and an array of 3D-printed components.

As seen in the video below, the device employs timing belts and pulleys inside the segments for power transmission and gear reduction in the horizontal direction. The Z-axis is driven by another stepper, along with a lead screw, held in place with a series of four rods and linear ball bearings. For the “hand” portion, a servo motor controls an end effector, enabling it to pick and place objects as necessary.

Gas Leak Detector Sensor | Fart Detector | Using Arduino Uno and MQ-2 Sensor | Methane Detector

Hello Guys I have Prepare a Tutorial Video on How You Can make a LPG gas Leak Detector Device using MQ-2 sensor and display the data on LCD In this Video I have Used MQ-2 Sensor with Arduino to Receive the Data from the sensor . MQ Sensor senses the air and send and sends it to the Arduino and the data is printed to the LCD Display .Then when the gas level crosses its threshold the light and buzzer are turned on and Alert is Displayed

Use SEFR (ML) on Arduino Nano for Color Recognition

A few months ago, some researchers published a paper called SEFR: A Fast Linear-Time Classifier for Ultra-Low Power Devices. It’s possible to run it on a regular Arduino Uno – more ever, to train the machine learning model on the device itself. Simply put, SEFR (which got its name from a related algorithm called semi-supervised ensemble learning guided feature ranking method) calculates a hyperplane between different classes of data with their average values.

Needless to say, as one who sucks at math, I have became very, very interested in this algorithm.

Tiny Machine Learning: The Next AI Revolution

Miniaturization of electronics started by NASA’s push became an entire consumer products industry. Now we’re carrying the complete works of Beethoven on a lapel pin listening to it in headphones. — Neil deGrasse Tyson, astrophysicist and science commentator

[…] the pervasiveness of ultra-low-power embedded devices, coupled with the introduction of embedded machine learning frameworks like TensorFlow Lite for Microcontrollers will enable the mass proliferation of AI-powered IoT devices. — Vijay Janapa Reddi, Associate Professor at Harvard University

Boca Can Teach Anyone About Robotics

This simple, 3D-printed quadruped robot is designed to explore control theory and machine learning.

Anyone can learn about robotics, but what if there was an inexpensive, hands-on approach? That’s where Boca comes into play. Nguyễn Phương Duy designed his open source, 3D-printed platform for makers and researchers interested in exploring control theory, machine learning, and reinforcement learning.

Boca has eight degrees of freedom with some great moves to help you in your robotics research and study. It can be purchased in two different flavors if you so choose: either fully assembled or with a kit that has the required components to get started with robotics. Duy is also making a 12-degrees of freedom variant, set to be released soon.
