When I showed my 60 NeoPixel LED clock prototype to my daughter and her girlfriend, and they both wanted to have one right away :-). Well, that clock was just a proof of concept, with lots of temporary wiring. So I decided this week-end to beautify it and to make it look nice and clean(er). There is nothing like a week-end project with adding a few more LEDs and features :-).
When I started this blog back on February 1st 2012 with a ‘hello world‘ post, I did not know where and how this well end up. WordPress.com (the host of this blog) counted 1862 views in that first month. 30 months later (time is flying by!), views they are beyond 100k every month! Thanks to you all for commenting and liking posts, which is very encouraging. And there was one suggesting made recently which I would like to address:
It always takes longer than expected: actually 4 weeks from the first board out of the reflow oven (“First New Zumo Board out of the Reflow Oven“), until I have it working on the Pololu chassis. But now I have a mobile Robot with WiFi, GPS, Bluetooth, nRF24L01+ and all the stuff I have dreamed off 🙂
The wired Ethernet connectivity works out of the box with the Freescale RIoT board :-). But to make it more ‘IoT’ capable, a WiFi connection would be a big plus. The element14 site did not tell which WiFi dongles are supported, and a thread in the element14 forum on that topic has not really provided much information. With some risks I decided to order the Wi-Pi WiFi dongle which seems to be popular in the Raspberry Pi community (thus that Wi-Pi name?). And as I anyway have a Raspy, my thinking was that if it does not work with the RIoT board, I still can use it with the Raspy 🙂
I understand the challenges of board vendors: they produce many boards, and typically they have an early/first firmware version on it. And when that board gets shipped to customers, that firmware typically is old and outdated :-(. Same for the RIoT board I have received: I was desperately trying some advanced features, only to realize that the firmware on the board is an older one from this year. So time to update the Android on that board.
Sometimes I have source files in my project which I do not want to get compiled (or excluded from build). Because as I’m using the ‘managed make’, all source files matching certain extensions (like *.c) are automatically included into the build.
To exclude a file from build, I right-click on it to get to the properties. There I can select a check box to have it excluded from the build:

This week-end tour with the motor bike was down to Italy and back through the alps. And it started with nice weather conditions:
At the university we have several projects with internet connectivity running. Yes, there is a hype around IoT, and in my view many false perceptions around this what it could or should be. Anyway, for these projects in many cases the Raspberry Pi boards are used, and I use a model B board of the Raspy too. I’m very happy with the Raspy, but I wanted to explore different options, so I ordered a RIoT board two weeks ago. When I looked at it the first time, I was thinking that this board could be a better (although larger) board than the Raspberry Pi one: more USB, more GPIO, micro-SD card, more processing power:
Well, then this week the new Raspberry Pi B+ came out: more USB, more GPIO, but same processing power as the standard B model.
