DIY pick and place machine from parts of scanner, inkjet printer, DVD player and vaccuum pump – Open Theremin – Urs Gaudenz
Posted by jpluimers on 2017/01/30
Urs Gaudenz manufactures Open.Theremin kits using his do it yourself pick and place machine which he built from low cost scanner, ink jet printer, DVD player mechanics and some Arduino controlling. Even his solder oven is Arduino controlled!
This is months of work showing a work flow in a 11 minute youtube video. Well done!

If anyone ever wants to have a batch of LTE dumb phones built…
Posted by jpluimers on 2017/01/09
If anyone ever wants to have a batch of LTE dumb phones built:
+Jeroen Wiert Pluimers I’m not aware of simple-voice-only phones with LTE modem. From my former life at a telephone producer i remember costs to get a platform running and the effort spend on special editions, i’d say if you are willing to buy 50000 we could find someone producing this for you. In China. But as written above, a basic-2G service (for M2M and emergency signalling or calls) will stay for long.

#220 feature `SKIP_FIRMWARE` by jpluimers · Pull Request #221 · Hexxeh/rpi-update
Posted by jpluimers on 2016/12/13
Reminder to self: Fix #220 feature SKIP_FIRMWARE by jpluimers · Pull Request #221 · Hexxeh/rpi-update
It’s bash. How hard can it be.
(no that was a rhetorical question).

Meet PoisonTap, the $5 tool that ransacks password-protected computers | Ars Technica
Posted by jpluimers on 2016/11/23
Too bad Ars Technica redirects https to http while preaching anyone should use https.
Anyway: OS device driver install and network configuration should probably be less automatic than it is now.
All the more reason to go fully https (hello LetsEncrypt, goodbye Embarcadero).
A video showing how it works is below.
The clever device emulates a USB ethernet adapter (that virtually every operating system has default drivers for) then fakes being 1.0.0.1 handing out DHCP address 1.0.0.10 with a netmask of 128.0.0.1 thereby routing almost all network traffic over it.
It makes a tiny peace of the internet unreachable (like 1.0.0.1 itself in Brisbane Australia).
More details on how it works at [WayBack] Samy Kamkar: PoisonTap – exploiting locked computers over USB.
Lets not leave this out:
Securing Against PoisonTap
Server-Side Security
If you are running a web server, securing against PoisonTap is simple:
- Use HTTPS exclusively, at the very least for authentication and authenticated content
- Honestly, you should use HTTPS exclusively and always redirect HTTP content to HTTPS, preventing a user being tricked into providing credentials or other PII over HTTP
- Ensure Secure flag is enabled on cookies, preventing HTTPS cookies from leaking over HTTP
- When loading remote Javascript resources, use the Subresource Integrity script tag attribute
- Use HSTS to prevent HTTPS downgrade attacks
Desktop Security
- Adding cement to your USB and Thunderbolt ports can be effective
- Closing your browser every time you walk away from your machine can work, but is entirely impractical
- Disabling USB ports is also effective, though also impractical
- Locking your computer has no effect as the network and USB stacks operate while the machine is locked, however, going into an encrypted sleep mode where a key is required to decrypt memory (e.g., FileVault2 + deep sleep) solves most of the issues as your browser will no longer make requests, even if woken up

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!
