This is my journey building an open source car system with Go & Qt, rear camera, live OpenGL map … Cross compilation In Part I, I had to patch qtmultimedia for the camera to work, but Qt compilation is resource hungry, same goes for the osrm compilation, the memory of the Raspberry Pi is too small. I had to to set up…
Thanks for the featured writeup Hackaday! Make sure to check out the comments over there as well. Looks like Hackernoon picked it up as well, make sure to check in with the comments there too. It would be great if you could also head over to Hacker News, give an upvote, and join in the comments there. Let's get this…
Why I switched to Windows 10 from macOS and built a water-cooled and overclocked 5.2GHz 6-core PC for photo editing with Adobe Lightroom Classic CC.
Back in 2015, I wrote a popular post comparing the performance of a number of microSD cards when used with the Raspberry Pi. In the intervening three years, the marketplace hasn't changed a ton, but there have been two new revisions to the Raspberry Pi (the model 3 B and just-released model 3 B+). In that article, I…
The holographic display of the future is here and you can have one on your desk for under $600. Ever since I saw Princess Leia appealing to Obi Wan that
I recently started FPGA programming and figured it would be fun to use an FPGA to implement the FizzBuzz algorithm. An FPGA ( Field-Progra...
I've used Macs as my primary computing devices my entire life. And though I continue to use a Mac for my primary workstation for both work and personal projects, my use of computers has evolved in the past few years quite a bit. With more of my stuff moving into the cloud and fewer software applications being…
Using high speed cameras, it’s possible to record the vibrations of everyday objects caused by nearby sounds and reverse engineer the sounds…essentially turning

Yesterday, during OsmoDevCon 2018, Steve Markgraf released osmo-fl2k, a new Osmocom member project which enables the use of FL2000 USB-VGA adapters as ultra-low-cost SDR transmitters. How does it wor
We've been archiving a bunch of old Xerox Alto disk packs from the 1970s. A few of them turned out to be password-protected, so I needed ...
I always love when I find a really dumb solution that works reliably to fix a problem that should never really be a problem in the first place. But having worked with audio devices before—though nothing nearly as complex as the AirPods—I am willing to cut Apple some slack in building a seamless aural experience with…
Looking inside the Intel 8087, an early floating point chip, I noticed an interesting feature on the die: the substrate bias generation circ...
Intel is in an increasingly bad position in part because it has been captive to its integrated model. Or, you could simply say they were disrupted.
When you read up on the DisplayPort connector in the VESA specification, it will show that both the source and the sink are supposed to provide power at 3.3V+-10% and 500mA on the DP_PWR pin, pin 20, of the connector.
Photo by Kevin Steinhardt When Azeem asked me to give a talk at CogX, he asked me to focus on just a single point that I wanted the audience to take away. A few years ago my priority would have bee…
Ault and Wiborg’s art nouveau poster ads.
The Intel Management Engine is an auxillary microprocessor embedded into modern Intel x86 CPUs or chipsets. 1 It runs an Intel-signed proprietary binary blob. Due to code signing restrictions enforced by the hardware, it cannot be modified or replaced by the user. (AMD x86 CPUs have a similar auxillary microprocessor…
I’ve been using Macs for almost nine years. I got a 15” MacBook Pro the summer before my freshman year of college through my school’s computer store. I used it for six years before getting a 13” model in 2015. I’m considering getting a new one in the next year or two, but the latest MacBook Pros have become worse in…
I don’t own an Apple Watch. I do have a Fitbit. But the Apple Watch 4 announcement intrigued me in a way no other product has since the original IPhone. This wasn’t just another product announcemen…
Since February 2016, I have been participating in DIYRobocars meetups here in the SF Bay Area, wherein a bunch of amateur roboticists compete in autonomous time trials with RC cars. I had been doing very well in the competition with essentially just a glorified line-following robot, but have lately upgraded to a full…
Last year Purism contacted me after they read on the Pepper&Carrot blog that my laptop has been stolen in the burglary of my house. At that time, they proposed me to contribute to my Pepper&Carrot project by sending me a shiny new Librem13 laptop. So, since October 2017 I have this laptop with me and because I saw a…
Move over, Sennheiser. Make yourself scarce, Bose. Here comes the ultimate Hi-Fi solution for your living room: The Commodore 64! I s it sa...
It was clear when Ouster started developing the OS-1 three years ago that deep learning research for cameras was outpacing lidar research…
When the iPhone X launched, a lot of designers were put off about the screen shape. Those complaints have mostly died down, but I haven’t…
In a stuffed apartment filled with hydrofluoric acid, oscilloscopes and a transistor curve tracer, Jeri Ellsworth carefully places a hand-cut silicon wafer into a 1000 degree furnace. The ambient noise of police sirens can be heard in the background: "Ugh, the police are coming... So the instructions for the…
