Approximate Computing

An article doing the rounds recently on approximate computing:

https://en.wikipedia.org/wiki/Approximate_computing

Approximate computing is a computation which returns a possibly inaccurate result rather than a guaranteed accurate result, for a situation where an approximate result is sufficient for a purpose. Approximate computing is based on the observation that in many scenarios, although performing exact computation requires large amount of resources, allowing bounded approximation can provide disproportionate gains in performance and energy, while still achieving acceptable result accuracy.

Battery Change

Easy Battery Change

Just a reminder that changing a battery on a G-Shock is easy and should not be avoided.

Raspberry PI 3 Adventures

We finally got our hands on the Raspberry Pi 3.


Tests, impressions and comparisons to follow.

One of the first comparisons will be to see what framerates this hardware can achieve with the 5MP camera and the software 'motion'.

Western Digital PIDrive

If you are lucky enough to live in a select few countries then Western Digital is willing to sell you a power reduce small form factor harddrive for use with your Raspberry Pi:

Intel announcing onboard FPGA on the same die as a Xeon processor

The Register has an interesting article on the announcement that Intel plan to ship Xeon chips with build in FGPA

Intel bought Altera last year.

Raspbery Pi GPS


Adding GPS location data to a Raspberry PI project is fairly easy.

The most common way is to add a GPS module that outputs text data on a serial port.

Below is a GPS module purchased on eBay that includes a Neo-6 GPS module, a Raspberry Pi specific PCB and a GPS antenna (not seen in the photo).


As soon as this module is powered up it attempts to send data over the UART pins.
