James Newman built himself a 16-bit Megaprocessor using transistors in frames taking 12 by 2 meters. Wow!
Posted by jpluimers on 2016/07/07
It took James Newman more than one and a half years of actually building progress and more than that (thinking about it started in 2011) for designing his own Megaprocessor using transistors.
For like EUR 50000 and a lot of “learning opportunities” he built himself a room full of visual computing: you can see the LEDs on all the PCB boards indicating exactly what’s going on (heck: he even made the RAM visualise an actual tetris implementation).
All for the sake of understanding transistors and discrete logic after which things got out of hand.
Hopefully a tech museum will buy this.
His site as a truckload of information, for instance the Source: Megaprocessor – FAQ: good/bad/ugly linking to lots of technical details and decisions made (like throwing out surface mount components but using lead based solder or having dual output logic).
There’s a lot of video too (like Megaprocessor – How ?) but – especially these weeks – the downloading is slow, to it’s faster and easier to watch his Youtube playlists:
They are currently 6 videos each, but he has uploaded more videos and is working on more.
Finally, James even built an assembler for this 16-bit processor. How cool is that!

Interesting: Somfy Smoove Origin RTS Protocol | PushStack a base to start Hacking Somfy.
The Somfy protocol is tricky as it uses rolling keys.

Obsolescence Guaranteed – PiDP-8 – powered by a Raspberry Pi
Posted by jpluimers on 2016/05/02
If you have a Raspberry Pi left, then you can make this:
The PiDP-8/I is a modern replica of the 1968 PDP-8/I computer. It’s open-source hardware, so schematics, design files & software are available.

Linux-Based Low-Latency Multichannel Audio System (CTAG face2|4)
Posted by jpluimers on 2016/03/24
Just wow (via Joe C. Hecht):
Linux-Based Low-Latency Multichannel Audio System (CTAG face2|4)
We’ve developed a multichannel audio system based on the AD1938 audio codec by Analog Devices and the BeagleBone Green (TI AM335X SoC).The audio system offers 2 stereo inputs and 4 stereo outputs.The whole project is based on open source software.To demonstrate the possibilities of the audio system, I’ve created a surround delay effect with the open source C++ library DSPatch by Marcus Tomlinson.Moreover I’ve created an automatic test based on GNU octave to evaluate the audio system characteristis, such as latency, THD+N, DNR, crosstalk and frequency-response.

Replace Boxee by Raspberry Pi as most TV support doing video+USB keybard over HDMI
Posted by jpluimers on 2016/02/22
If for instance your Boxee gets old or breaks down, you can use a Raspberry Pi as a replacement with Kodi as media player.
This combination will understand the Video+USB over HDMI which most TV supports officially named HDMI-CEC , but most vendors “invented” their own names (see list below).
The core is the kodi support for CEC.
Basically it comes down to using three cables going to the Pi: Power from TV (or some other source), HDMI to TV, and wired Ethernet. And a distribution for RaspberryPi containing kodi will work, for instance from OpenELEC Mediacenter – Download: Raspberry Pi Builds
Chad MILLER has more details on how to get this to work: My Boxee box is getting old, but I knew of no replacements. The problem is I …
Names known for HDMI-CEC via Wikipedia:
Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link and Regza Link (Toshiba), RIHD (Remote Interactive over HDMI) (Onkyo), RuncoLink (Runco International), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
Because of the naming, turning on CEC can be confusing: How to Enable HDMI-CEC on Your TV, and Why You Should

Can a Raspberry Pi do NAT port forwarding to a non LAN address? If so, what distribution would be the easiest one?
Johannes Self added some nice comments for generic Linux distributions in the G+ thread, but just in case my blog readers have even more concrete answers…
