Mobile Raspberry Pi with ANY iPad. No USB-C needed.
Following on my from earlier video about pairing the Raspberry Pi 4 with the iPad Pro over USB-C, this video show how to pair any iPad (or iPhone, or Android tablet) with a Pi4 or a Pi3 over WiFi.
Not only that, but this solution solves the problem of how to charge the iPad while using the Pi, and provides a really nice interface for working with WiFi while on the go.
A Uranium Glass Marble Ring Oscillator for Your Next Steampunk Project
If you’ve never considered owning a greenish, slightly radioactive device that glows in a circular pattern, then this Uranium Glass Marble Ring Oscillator, or UMRO might change your mind. It nominally runs on a 9V battery, and is small enough that it could be worn as a steampunk-style pendant or placed into an antique flashlight case as creator Aeon Junophor did with his. Or one of his at least, as he’s geared up to build multiples of this interesting unit.
How to Recycle Cardboard into Anything with 3D Printing!
Paper is an incredible material, but why does it always have to be flat? I’ve developed a process to turn paper into a three-dimensional material, using as little as a 3D printer, a blender, a vice, and pinch of rice.
The resulting material has the texture of paper, but is as hard and rigid as plastic, moldable into an infinite variety of shapes, and completely biodegradable.
Building an Arduino-Based SSD
Normally, SD cards are used to store large amounts of data when logging information or retrieving files. However, SD cards have slow access times and require 4 GPIO pins, along with more software overhead. When using microcontrollers that are short on RAM and/or GPIO pins, such as the ATtiny family, storing large amounts of data while keeping a program small can be a large issue.
Build an 8 GHz Sampling Oscilloscope with Analog Devices’ ADCMP582 Comparator
Oscilloscopes, you don’t always need one, but when you do the good ones can cost quite a bit. There is hope. Instead of buying an expensive piece of equipment, others such as programmer Ted Yapo, decide to create their own, which he has done with his open source 8GHz Sampling Oscilloscope.
Giant 3D Printer from Scratch!
It works! The Big 3D Printer MkII is finished and it works beautifully. I made a first test print of a 66mm combination wrench, 800mm in length with absolutely no warping!! It shows a few holes in the top because it has too little infill but hey! it is the first print!! It took only 6 hours but I’m sure that this thing can go way faster.
Water Cooling is DEAD. Meet the THERMOSIPHON!
The startup IceGiant is trying to change the computer cooling landscape – and according to our testing they’re off to a good start.
