Teamviewer - using aliases

I really like teamviewer (free for personal use), after creating an account and running it on most of my machines and my android tablet the one thing i couldn't find easily figure out was why one of my machines had a human readable name and all the others showed up with just the teamviewer id.

The annoying thing is that only the machine with the human readable name has an option to change its properties and the others only allow me to connect to them. Googled for an answer for ages, must be a typical case of me searching using the wrong keywords or nobody else trying to do this...

Finally after messing around for ages i found that i had to add the machines manually in computers and contacts (not logical as they're in my list already...), then you get the option to add an alias (grumble: why do have to type in the teamviewer id - would like to see a rightclick option for that).

Great now i'll be able to connect to the correct machine in one go without having to memorize the teamview id.

As a 'benefit' the machines are now listed twice: directly in the 'my computer' list and once under my account. And there must be some logic as to why the machines show up yellow (idle) under the account but green (active) in the 'my computer' list.

Key-fob is sorted, can we do the same for URUK WiFi Router Module (Arduino Compatible)

Cool! The Pi-Lite key-fob (see yesterday's post:Get a Pi Lite and we'll all a Pi Lite key-fob as a bonus!) should be happening as they went over £10K today.

Can we do the same for URUK WiFi Router Module (Arduino Compatible) , i'd like to get one of those ... currently at just over $6K, there is another week to get it funded at $10K.

Get a Pi Lite and we'll all a Pi Lite key-fob as a bonus!

There is always something interesting on Kickstarter...

Pi Lite white - Bright white LED display for Raspberry Pi

If they reach £10K (easy, the project is over £9 already) we'll all get the Pi Lite acrylic key-fob as a bonus, so go on get one!

Don't have a 3D printer yet? Do something about it!

A couple of Kickstarters worth looking at:


Rigidbot (build volume: 10"x10"x10" /  25.4x25.4x25.4cm or 12"x16"x10" / 30x40x25.4cm)
Some people are worried that they're not going to reach all their stretch goals... The initial goal was only $31.5k, now to get the heated print bed they need 31.7x that, currently they at almost 60%. You can make it happen!


Cyrus (build volume: 10"x11"x12")
Almost half way to the goal, looks great. Like shiny things? Like Swarovski gems? Then go for the Great Reward whilst it's still available. Don't forget to add the heated bed, lcd and dual extruder!


So you choice is simple: get a Rigidbot. Or a Cyrus. Or a couple of both. Or 31 Cyruses / 750 t-shirts! Come on, what are you waiting for?

36
And whilst you're at it don't forget to get a couple of these: Doodle 3D Wireless 3d printing and a way to get the kids hooked also (kids: sell it to mom and dad as an educational tool and you'll get to play with the 3d printer once they're bored with it), what more can you ask for?

Arduino + Canbus shield + GPS Receiver - update 1

A quick update on my Arduino + Canbus shield + GPS Receiver post from last year.

I had this plan to put the files in a sub folder in order to make sure that i would hit the limit to the number of files in the root of the file system, added a bit of code that would create up to a thousand files. Somehow it didn't work: didn't want to write in the sub folder...

But why use separate files anyway? The files will be evaluated on my main machine, it's easy enough for it to split the file. That simplifies the code a lot:


void start_new_file(void) 
{
 digitalWrite(LED2, HIGH);

 // we want to add to the end of the file file and flush manually for performance and to be nice to the sd card
 file = SD.open("DATA.TXT", O_READ | O_APPEND | O_WRITE);
 digitalWrite(LED2, LOW);
}

Also spotted the post Why is the SD library slow? and decided to flush the file manually. Performance isn't really an issue but fewer writes to the SD won't hurt! I flush before checking for the click.
