  1. I also have many hundreds of euro's of tinkerforge stuff, but I'm 100% in favor of moving forward. Even if that brings some short term inconvenience. The current connectors are a weak point in an awesome system.
  2. Hello guys, I'm trying to design a custom control panel in inkscape that will be cut out of wood or plastic by a laser cutter. Can you share the design files for the cases with us so I can re-use some parts of it. Of course I'll post my design files as well. kind regards, Geert.
  3. Hey guys, The blog post about the master brick 2.1 says: Does this mean the 2.1 version of the master brick can use 8m bricklet cables since every bricklet port has its own bus?
  4. Hello everyone, I'd like to point you to an interview I did yesterday where I use Tinkerforge stuff to demo the RedHat Fuse product: http://blog.eisele.net/2014/10/developer-interview-di-6-geert-schuring.html Skip to around 8:00 if you're in a hurry Tinkerforge rocks guys!

  6. Hey Guys, I think it would be a great idea to create a bricklet that can control a display like this: http://www.adafruit.com/products/250 They are quite cheap, and the resolution combined with RGB backlight is just awesome! kind regards, Geert.
  7. Hey Guys, In a couple of months my employer is moving to a new office space. Several weeks from now the building will be prepared for our needs, which is the perfect opportunity for me to install some tinkerforge stuff throughout the office. If I can come up with a reasonable plan my employer will consider this. What would be the best/cheapest way to connect about 8 to 10 separate master bricks with each other?

  9. Thanks again. And congrats on your 1k forum posts.
  10. YES that worked! Awesome. I can now hook a whole bunch of bricks and bricklets to my odroid. GREAT! Thanks a lot for taking the time to look into my problem. Its very much appreciated!

  12. Thanks for your replies. I'm trying out several different setups to be able to answer your questions. I have a couple of answers already: - I'm seeing the problem on linux only. If I connect 3 master bricks using long (5m) usb cables and a USB hub to my Macbook Pro I have no problems at all! - The linux PC that I want to use is an Odroid U3. - The problem is not related to a particular cable or brick. - I can connect as much bricks as I want to the Odroid which all works fine... until I disconnect brickv from brickd and try to reconnect. So it looks like there's a problem in the brick/bricklets discovery mechanism on linux when a client connects. I have a Windows 8 laptop in the house (ugh) so I'll test on that one too. I'll have more answers in the coming days.
  13. Hey fellas, I'm running into trouble connecting multiple master bricks over USB to my PC. I have 3 master bricks installed in different rooms in my attic, and connect those with USB cables to a powered USB Hub, which is connected to my PC. However, if I connect more then 3 master bricks to the HUB brickv can no longer connect to brickd. If I attach 2 master bricks, then connect with brickv, and then connect the 3rd master brick to the USB Hub, I can see the third brick appear in brickv less then a second after plugging it in. But If I then disconnect brickv and try to reconnect it fails, and keeps failing until I disconnect one of the bricks. If i remember correctly I also get problems if I connect 2 master bricks with USB cables to 2 different USB ports on my Macbook. Are there any such problems known to you? These use-cases are quite important to my setup, so I would be more then happy to give more details on this problem in a Google Hangout or something. Kind regards, Geert Schuring.
  14. Hey Guys, I wouldn't buy any of these boards (voted). I love tinkerforge (spend over 400 euros on it, and not done yet ) so I'm not just being negative. I honestly think it would be a waste of time and energy to develop a new device from scratch when things like the Raspberry Pi (huge community) and the ODROID-U3 (1.7 Ghz Quad core, 2GB RAM, link: http://hardkernel.com/main/products/prdt_info.php) are available for around 50 euro's. You could turn these into a dedicated development board by shipping them with a custom OS image. Using commodity hardware would always be my preference. Another thing that I would be much more interested in is more documentation about how to write custom firmware that would make a standard master brick able to operate on its own without a PC-device connected to it. Or maybe allow the brick viewer to upload simple scripts to a master brick, that would be even better. Hope you find my feedback valuable. Unfortunately the German forum is very difficult for me to read so I can't really follow what's being said there. Kind regards, Geert.
