Hardware Hands-On

You have little chance today to get your hands dirty with electronics or computer hardware, either we deal with small devices like mobile phones, tablet and notebooks which are not made to be opened and tinkered with or our hardware is virtual only and sits in the cloud (no screwdriver required). Few people now still own a desktop size PC where one can add or change hardware (major hardware companies claiming massive loss due to dropping sales in this market).
During my studies in the 90’s we still dealt with CPU’s at a very low level which helped to ‘see’ and understand what’s going on.

If time allows I am doing some DIY  projects with Arduino or Raspberry Pi, 2 electronic platforms which seam to be similar at the first glance, but operating very differently.

The Arduino is a progammable microcontroller, designed to work with sensors or to control external components like relays or motors. Is a very hardware oriented device, no OS or whatsoever included. It does basically what you program it to do. More info and getting started at http://arduino.cc



The Raspberry Pi on the opposite end is rather a miniature computer, running an OS from a SD card and equipped with ethernet, HDMI and USB plugs. It is clearly more a software platform which can be used for more powerful applications than the Arduino. More info and getting started at http://www.raspberrypi.org

You have the option to combine both, to have processing power of a computer and the myriad of inputs and outputs to the real physcial world.

Crowdfunding Projects I back (2)

Another small project I backed is the Gamebuino, an Arduino based retro game console. Simple concept to pick up basic game programming with this 8bit gadget that reminds me of the Gameboy that Nintendo launched in April 1989. Amazing, the one-man project managed to gather 1.000% of the funding he asked for. The device was funded for 25$ as early bird backer.

Hardware History Lane – Casio Cassiopeia

Over the years we spend a lot of money into gadgets and electronics, only to see its value dropping to zero and being out-dated the moment you open the box the first time. While doing some spring cleaning I unearthed the  Casio Cassiopeia that I bought in 2001 (for ~800.- DM) , surprisingly it still charges and works.

Casio Cassiopeia EM-500G

This is EM-500G, a slimmed down version of the E-125. Some specs:

  • CPU: NEC VR4122 MIPS (150 MHz)
  • Memory: 16 MB ROM
  • Display: LCD, 240 × 320 Pixel, 65536 Farben
  • Interfaces: Seriell/USB and IrDA
  • MultimediaCard Slot
  • Windows Poecket PC 3.0

Compared to todays mobile phone and tablet hardware seems like nothing (vs. eg. a dual-core 1.7 GHz and 2GB of a Samsung Sx phone).
I am just wondering what we gain in 13 year with CPU speed times 10 and memory times 100 from a user point of view ? Yes, we have Android and iOS with 1.000.000 applications to download, 3D Games on HD screens, music and videos (the Cassiopeia  can handle that too to some extent), but the basic features are still the same. I used the Cassiopeia that time to remote dial in into Unix servers, using a Siemens S35 as modem.

Crowdfunding Projects I back

Crowdfunding becomes more and more popular with many successful projects coming out of the various platforms in the web (most Kickstarter and IndieGoGo). I like the idea of independent smart people coming up with an idea and let a product or concept take off without backing by a huge MNC (though these companies might buy a crowfunded project and turn off supporters, but that is another story). I believe crowdfunding can be a source of genuine products which are not made solely to hog patents and increase shareholder values.

Doing panoramic and spherical photography for more than 15 years now, I am excited about the new ideas, technologies and products coming up.
Sometimes you should follow your ideas or visions, I did some basic research for an own panorama rig similar to the projects below back in 2007 (link), but did not really complete the project and with the requirement to export the images and stitch them in the PC it was not very practical. In 2007 I did not see the option to stitch with hardware on-board.

One already successful funded project is the Panono Camera Ball (a camera in the shape of a ball thrown into the air to snap an full spherical images with 36 small cameras built-in).


2 new projects that are still in the funding phase I back with 300 U$ each. Both try to create 360 degree images and videos

The CentrCam
At the time of writing the project still have to fund another 360.000 U$ in 6 days, seems to become unlikely being successful.

The 360Cam
which is already 280% founded.

Lets see who makes the race (they are not competing I guess) but is a bit strange that the 360Cam has a target of 150.000 $ only, with a much richer feature and quality list compared to the 900.000$ target of the CentrCam that would output video in a lower quality and smaller resolution. Anyway lets wait for the funding results, I am happy to support both (at least I add both to my panorama collection).

FB aquires WhatsApp – Bye and Thanks for the Fish

WhatsApp known for its massive security issues, still used by millions of people as a free replacement of SMS and MMS, was acquired by FB, one (maybe the) biggest data harvester in the internet. I dont use FB, the acquisition is a reason to finally move on to another more secure communication tool: Threema  (Made in Switzerland app with end-to-end encryption). Hope they wont sell privacy for money. Please help to spread the word.

It is NOT free, but is time to understand FREE comes at a price !
