I asked +Simon Stuart​ “can you make your Raspberry Pi 2 devices crash by flash light?” he did: it fails!

Posted by jpluimers on 2015/02/09

Too bad: it is indeed possible to restart a Raspberry Pi 2 by using a high power flash.

It appears that U16, the SMPS chip, is the culprit.

Yes, bit of bluetac on that chip and it survives the flash

Source: Raspberry Pi • View topic – Why is the PI2 camera-shy ?

Simon Stuart checked it:

it’s true!

Put the high-power flash (which I believe uses a Xenon bulb) on my camera, and behold a shot to the top of the board does indeed crash it every time!

Never in a million years would I have thought such a thing were possible!

At first Simon could not reproduce it: you really need a high power flash.

I’m glad I didn’t order any Raspberry Pi 2 yet.

USB Typewriter — Classic Typewriters for the Digital Age (for mechanical typewriters, not electrical ones)

Posted by jpluimers on 2014/03/19

Nicely done: the USB Typewriter — Classic Typewriters for the Digital Age, as they can do almost all keys a PC keyboard can do see the USB Typewriter — FAQ using a mechanical (not electrical!) typewriter.

Basically the opposite of  the IBM Selectric Computer Terminal, the Daisy wheel printing, the IBM 1050 systemand the IBM 2741 Console.

Note the kits (there are both soldering and non-soldering versions) are mostly aimed at models that once were popular in the USA, so for manufacturers like Adler there are no guidelines (but the existing guidelines for soldering and for non-soldering probably work fine).

Jean-Luc Aufranc. is a great guy with lots of knowledge in the embedded world (read his resume).

I’ve been interested in Raspberry Pi experiments for a while now, so I was glad that today he pointed me to this very nice kit:

You can get it through DealExtreme, which I will do soon.

(I just saw how a guy is using a massive amount of Raspberry Pi and custom ASICs to mine for BitCoins)
