Fresh hacks every day
Years ago we covered using thermite to destroy a hard drive. The idea is that if you melt through the platters, the data is completely unrecoverable. There are tons of videos of people doing this, but they all have a similar format. There’s a hard drive, with a flower pot or soda can sitting on top full of thermite. … Read the rest
This lantern was built from recyclable goods. It’s a bit dangerous when used like the image above, but [The Green Gentleman] does give you a few other options in his build instructions which make for much safer operation.
The lantern enclosure is made from old cans and a glass jar. He screwed a couple of boards together at a right … Read the rest
We’re surprised that we haven’t come across any of [Robert Murray-Smith's] projects before. Looking through his collection of YouTube uploads proves that he’s a very active amateur chemist (we assume this is a hobby because he performs the experiment in a mayonnaise jar). The video we’re featuring today is about ten minutes of his technique for synthesizing graphene. The … Read the rest
If you’ve ever used an extruding 3D printer, you know that the resulting prints aren’t exactly smooth. At the Southackton hackerspace [James] and [Bracken] worked out a method of smoothing the parts out using vapor. The method involves heating acetone until it forms a vapor, then exposing ABS parts to the vapor. The method only works with ABS, but … Read the rest
We think that anyone who’s done at-home PCB fabrication will appreciate the tidiness that [Fran] maintains throughout her etching process. She recently posted a three-part video tutorial which showcases her techniques. As you can see in the screenshot above, her habits reek of top-notch laboratory skills.
Regular readers can probably guess what circuit she’s etching. It’s the test boards for … Read the rest
If you’re thinking of trying the acetone-vapor polishing process to smooth your 3D printed objects you simply must check out [Christopher's] experiments with the process. He found out about the process from our feature a few days ago and decided to perform a series of experiments on different printed models.
The results were mixed. He performed the process in … Read the rest
One of the issues with extruder-based 3D printing is that it can be very difficult to print objects that have voids in them. You simply must have something to deposit the soft material on until it has a chance to harden. [Matt] found a solution which should work for any extruder-based printer (with one caveat we’ll get to in a … Read the rest
