Dutsfilter

Hi


Got a nice Case with lots of fancy LEDs..
But it still needs a dust filter on its giant three fan intake.




Mosquito netting.. bought at some stage for very cheap for unknown reason..

And it comes with magnets!

Cut it stick it be happy.. that was easy.

Bike odometer

I wanted to get a bike odometer... Well there was still my old galaxy 3 lying around... It's even water resistant.
Holder for 1€ from China.

First GPS fix with a new firmware (OMA)

Digihud as the odometer.(using GPS) It also fearures a HUD display overlaying other software.

And since I don't know where to stop:
For navigation be on road.

All apps need to be loaded via apk since the device is way too old for play store.

Next step: power over the generator from the bike with a buffer battery.

Door closer

So our cat always wants to walk in... But I wanna have the door closed... First prototype... In the end the rope is white and all the stuff should be on the left side of the door. Can easily be adjusted by adding or removing water.

Designer Lamp

Oh what a nice lamp...
330€? !!!!!! No way... let's get to work!

Easel: 19€
Lampshade (Ikea): 24€
Lamp: 1.99€
Cables and bulb fitting: 5.50€

Total:  50.49€ ;)
Total work time: 30 min


First I got rid of all the stuff not needed since we will not have to hold a picture with it. The bulb fitting was grinded down a bit on the sides to fit between the wooden parts. The wood piece at the top was moved down to make room for the fitting. I just screwed the fitting in with two wood screws. (Tight!)


That's it..

Nice lamp:
And fully extended:

Cat Communicator

So during the holidays we had to leave Jack alone (apart from neighbours and cat-sitter). And of course we wanted to check in with him from time to time to see how he is doing.
So I got a cheap Webcam and a very old Aspire Aspire One 150D (I painted It red at some stage... ). Lubuntu running on it btw..

First I had to open up the Webcam and disable the LEDs. I had no way of switching them off with Linux. And by disabling I mean just cutting them off.. ;)

Next step: Hook up two 2€ servos and a bit off leftover wood.

And the whole thing from the other side.. took like 5min...



Since it tends to be a bit dark in Hamburg sometimes there is also an LED from an old torch:

The LED works fine directly on the Arduino pin which was a bit unexpected.
I don't need to write about the Servo libraries for Arduino.

To communicate I use Skype (no need for dyndns, there is an IP grabber)
You have to set Skype to auto accept calls.
And to communicate with Arduino I just log in to the shell via ssh.

Commands to the Arduino with:
 
echo "command" > "your ard e.g. /dev/ttyACM0"
 
 
 
 


Careful! The Arduino reset needs to be disabled in order to use the echo command:










The whole setup:















And a screen-shot from a Skype session during the holidays:




I know... he was a bit confused...
