Truckla Gets an Open Source Charging Buddy

Posted on April 11, 2023 by Navarre Bartz

A red Tesla Model 3 converted into a pickup truck with a black lumber rack extending over the roof of the cab sits in a grey garage. A black and silver charging robot is approaching its charging port from the right side attached to a black cable. The charging bot is mostly a series of tubes attached to a wheeled platform and the charging connector itself is attached to a linear actuator to insert the charging device.

More than three years have passed since Tesla announced its Cybertruck, and while not a one has been delivered, the first Tesla truck, Truckla, has kept on truckin’. [Simone Giertz] …read more Continue reading Truckla Gets an Open Source Charging Buddy→

Tempus Nectit, a DIY Knitting Clock with Instructions

Posted on April 5, 2023 by Navarre Bartz

A white, house-shaped clock with the words "TEMPUS NECTIT" written in faux Roman script in black on a strip of silver at the base of the "roof." a white power cord extends from the left of the enclosure, and the center of the clock is a 22 pin knitting machine wheel with one pin covered in silver metalic. A white plastic peg extends from the bottom right of the enclosure to hold the feedstock yarn.

We’re no strangers to unusual clocks here at Hackaday, and some of our favorites make time a little more tangible like [Kyle Rankin]’s knitting clock. Inspired by our coverage of …read more Continue reading Tempus Nectit, a DIY Knitting Clock with Instructions→

Biohybrid Implant Patches Broken Nerves with Stem Cells

Posted on March 30, 2023 by Navarre Bartz

A clear flexible PCB with a number of gold electrodes on one end. It is wrapped over a black cable to demonstrate its flexibility. A set of dashed white lines goes from one end to a zoomed in image of the circuit structure inset in the top right of the image.

Neural interfaces have made great strides in recent years, but still suffer from poor longevity and resolution. Researchers at the University of Cambridge have developed a biohybrid implant to improve …read more Continue reading Biohybrid Implant Patches Broken Nerves with Stem Cells→

Grow Your Own Brain Electrodes

Posted on March 24, 2023 by Navarre Bartz

A clear droplet sits on a blue PCB with gold traces. A syringe with a drop of clear liquid sits above the droplet.

Bioelectronics has been making great strides in recent years, but interfacing rigid electrical components with biological systems that are anything but can prove tricky. Researchers at the Laboratory for Organic …read more Continue reading Grow Your Own Brain Electrodes→

ISA over TPM to Your PC

Posted on March 23, 2023 by Navarre Bartz

A green PCB with an ISA card slot and various connectors and components. The text "DISAPPOINTMENT LPC to ISA Adapter" is printed in the bottom left of the board.

Sometimes you really want to use your legacy SoundBlaster instead of emulating it for classic games. While modern PCs don’t have ISA slots, [TheRasteri] is fixing this shortcoming with his …read more Continue reading ISA over TPM to Your PC→

A Little Chess with Your Timepiece

Posted on March 23, 2023 by Navarre Bartz

A metal watch is held in a man's fingers. The watchface has a laser etched chess board with miniature chess pieces made of brass enacting a match. The time is told on an etched chess clock to the right hand side of the timepiece and a small window on the rightmost "clock" shows the date.

Some things remain classics, even after centuries, and chess and watches have certainly stood the test of time. [W&M Levsha] decided to combine them both in this “Chess Club” watch …read more Continue reading A Little Chess with Your Timepiece→

While some might say we’re living in a cyberpunk future already, one technology that’s conspicuously absent is wetware. The Unconventional Computing Laboratory is working to change that. Previous work with …read more Continue reading Unconventional Computing Laboratory Grows Its Own Electronics→

Electronic Bandage Speeds Wound Healing

Posted on March 12, 2023 by Navarre Bartz

A closeup of a ring and "flower" electrode attached to a translucent piece of material with fainter wires. The flower and ring electrodes are made of molybdenum that has a somewhat accordion fold back-and-forth cross-section.

We’re a long way from the dermal regenerators in Star Trek, but researchers at Northwestern University have made a leap forward in the convenient use of electrotherapy for wound healing. …read more Continue reading Electronic Bandage Speeds Wound Healing→

AGES of Renewable Energy Storage

Posted on March 3, 2023 by Navarre Bartz

As society transitions toward renewable energy sources, energy storage inevitably comes to mind. Researchers at the University of Illinois at Urbana-Champaign have found one way to store renewable energy that …read more Continue reading AGES of Renewable Energy Storage→

A Look Inside Bicycle Gearboxes

Posted on March 2, 2023 by Navarre Bartz

A line art schematic of a bicycle CVT drive. Two large green circles at the bottom have the text "1. Increases speed" where the crank arm would enter the system. A series of cam arms highlighted in red say "2. Converts from rotary to reciprocating motion." Finally, a blue highlighted bearing says "3. Converts from reciprocating back to rotary motion."

While bicycle gearboxes date back to at least the 1920s, they’re relatively unseen in bike racing. One exception is Honda’s race-winning mid-drive gearboxes, and [Alee Denham] gives us a look …read more Continue reading A Look Inside Bicycle Gearboxes→
