Arachnid Ale Uses Yeast to Make Spider Silk

Posted on by

Many people who read Hackaday hold the title of “Webmaster” but [The Thought Emporium] is after slightly different credentials with the same title. He aims to modify a strain of yeast to produce spider silk. Charlotte’s Web didn’t go into great detail about the different types of silk that a spider can produce, but the video and screencap after the break give a rundown of how spiders make different types of silk, and that each species of spider makes a unique silk. For this experiment, the desired silk is “beta sheets” which the video explains are hard and strong.

Some …read more

Most of us have heard some form of the adage, “You can buy cheaper, but you’ll never pay less.” It means that cheaper products ultimately do not stand up to the needs of their superior counterparts. Hackers love to prove this aphorism wrong by applying inexpensive upgrades to inexpensive tools to fill up a feature-rich tool bag. Take [The Thought Emporium] who has upgraded an entry-level microscope into one capable of polarized and dark-field microscopy. You can also see the video after the break.

Functionally, polarized images can reveal hidden features of things like striations in crystals or stress lines …read more

Wireless Charger Truck Mod Keeps Juice Flowing On The Move

Posted on by

Wireless charging is great tech, but its relative novelty means it may not be everywhere you want it. When one of those places is your vehicle, well, you make like [Braxen McConnell] and crack it open to install a wireless charger!

After dismantling the centre console, [McConnell] had to make a few cuts behind the scenes to make room for the wireless charger — as well as cutting down the charger itself. He also took apart the charger and flipped the board and charging coil around inside its case; the reason for this is the closer the coil is to …read more

Wideband Woes and the Junkbox Miata

Posted on by

As ever, I am fighting a marginally winning battle against my 1991 Mazda MX-5, and this is the story of how I came to install a wideband oxygen sensor in my Japanese thoroughbred. It came about as part of my ongoing project to build myself a viable racecar, and to figure out why my 1990s Japanese economy car engine runs more like a late 1970s Malaise-era boat anchor.

I’ve always considered myself unlucky. My taste for early 90s metal has meant I’ve never known the loving embrace of OBD-2 diagnostics, and I’ve had to make to do with whatever hokey …read more

Different Differentials & The Pitfalls of the Easy Swap

Posted on by

I dig cars, and I do car stuff. I started fairly late in life, though, and I’m only just starting to get into the whole modification thing. Now, as far as automobiles go, you can pretty much do anything you set your mind to – engine swaps, drivetrain conversions, you name it – it’s been done. But such jobs require a high level of fabrication skill, automotive knowledge, and often a fully stocked machine shop to match. Those of us new to the scene tend to start a little bit smaller.

So where does one begin? Well, there’s a huge …read more
