While I'm a hacker of all kinds of electronics things by night, my day job is being a software developer. That mostly means sitting in front of a computer all day, entering code, debugging, etcetera. You probably can imagine my main weapon of choice to tame all that code is my keyboard: I'm usually happily tapping…
An experiment to understand how the discrepancy between logical and native screen dimensions on the iPhone 6 Plus affects rendering quality.
What does it take to build a little 68000-based protoboard computer, and get it running Linux? In my case, about three weeks of spare time, plenty of coffee, and a strong dose of stubborness. After banging my head against the wall with problems ranging from the inductance of pushbutton switches to memory leaks in the…
What does a recycled (heavily used) go kart tire, an action-packed three-phase servo drive and a gyro/accelerometer have in common?
(Update 2014-10-30: Due to some interest in this project, I added schematics for the GALs)
I am making a brain for my model plane so that it can fly by itself. I could have bought an off-the-shelf kit but I wanted to build it myself to understand how everything works from the ground up.
The latest version of the Intel manual has a couple of new instructions for non-volatile storage, like SSDs . What's that about?
There was a recent thread about the Apple 1’s noisy -5 volt supply on Applefritter , so I asked Woz the following:
Please forgive me for the lack of new content over the last five or so months. After my most recent post about neural networks and quadcopte...
This led to some general discussion that this particular device really is in a class of devices, now called the "killers", which need to be made.
The 8-bit Z80 microprocessor is famed for use in many early personal computers such the Osborne 1, TRS-80, and Sinclair ZX Spectrum. The Z80...
If you look closely at the datasheet for a Z-80 chip, you'll notice the data pins are in a random-looking order. The address pins (A) are ni...
Nobody doubts that the C64 was the greatest selling single computer model of all time, it even made it into the Guinness Book of World Records, but nobody quite knows how many it really was: Most sources say 17 million, others say 22 or even 30 million. With a high degree of confidence, I can now…
[Note to the impatient: to try out my beamforming simulation, which produced the above image, visit my beamlab test page - ideally in a brow...
Samuel Clay is a grad student in the schools of design and of engineering at Harvard. He founded NewsBlur , a personal RSS news reader, and Turn Touch , beautiful control for the smart home.
Update: It turns out my 7805 isn't counterfeit. eclectro did an in-depth search ( details on reddit ) and found an old 7805 datasheet fro...
Last year, a group of Media Lab students visited Shenzhen with, bunnie, an old friend and my hardware guru....
3d printing projects, Ultimaker and other DIY 3d stuff
A very warm welcome to my most ambitious project to date. In this project I’m going to attempt to design and build a sprite-based graphics accelerator that will function as a co-processor to an MCU. Using cheap off-the-shelf components I’m hoping to achieve a level of gaming performance that compares well to popular…
