General Discussion / bricklet cases design files
« on: January 30, 2015, 17:43:03 »
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.

General Discussion / Maximum bricklet cable length
« on: January 01, 2015, 21:34:39 »
Hey guys,

The blog post about the master brick 2.1 says:

Quote
With a Master 2.0 and four Bricklet connectors, the maximum bus length was 4x2m = 8m. To increase the electromagnetic immunity, we split the I2C bus into four different buses with an I2C hub.

Does this mean the 2.1 version of the master brick can use 8m bricklet cables since every bricklet port has its own bus?

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:

Skip to around 8:00 if you're in a hurry :)

Tinkerforge rocks guys!

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.

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?

General Discussion / Problem with multiple Master bricks
« on: March 11, 2014, 14:43:27 »
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.

General Discussion / 20x4 OLED Display
« on: January 10, 2014, 12:08:04 »
Hey guys,

I came across the following:

Might be a good replacement for the LCD versions. OLED has *much* better readability.

Hi fellas,

Any idea when the motion detection bricklet will be available and what its price is going to be? I plan to install motion sensors in every room of my house and use the feedback to switch lights.

Now I could use a 5v motion detector sensor with the IO bricklets, but if Tinkerforge has a bricklet coming at a reasonable price I'll wait for that.

I've seen the bricklet in the server room kit, so I hope its about to hit the shop!

General Discussion / Request: Larger mounting plates
« on: October 16, 2013, 11:43:42 »
Hi,

Could you add a larger mounting plate to your shop? Preferable one that is at least 4 times larger then the current largest one. I can always saw a bit off when its to big. The current plates arent big enough to fit a master brick and a single io16 bricklet. Also, I would like to mount a master brick and several dual relay bricklets on 1 plate.

Hope you can make this happen.

Kind regards,
Geert Schuring.

General Discussion / Ethernet extention fairly expensive
« on: August 21, 2013, 15:18:13 »
Hey folks,

I really like the Ethernet extension but the price is keeping me from buying several of them. Especially since you also need a master brick, and the bricklet cables only reach 2m. That means I need about 7 or 8 master bricks spread throughout the house. The Ethernet extension is really great because I can reuse the Ethernet cables already present, but its so expensive that buying a set of raspberrypi's instead looks like a realistic alternative.

Could you explain a bit about the reasons for the high costs of the Ethernet extension?

thanks,
Geert.

General Discussion / Industrial bricklets...

Could you clarify what you mean with industrial bricklets, and when they are expected to become available in the shop?

General Discussion / Motion sensor
« on: August 16, 2012, 15:42:47 »
Hey folks,

I'd like to use a motion sensor in my home, and came across the following component: http://www.conrad.nl/ce/nl/product/172500/PIR-SMD-bewegingsmelder-3-12V2mA

Can you create a bricklet for this, or explain how I can use an existing bricklet to connect this censor?

General Discussion / LCD20x4 freezes
« on: August 14, 2012, 19:25:34 »
Hey folks,

I'm having trouble with my LCD20x4 after upgrading the master brick firmware to the latest version today.
After a certain amount of time the backlight is somehow disabled, and the LCD no longer responds to any commands send from brickv or my Java program. The buttons are still functional thought! I can see brickv reporting "pressed" and "released" when i press the 3 buttons.
There are no errors reported by either brickv or the running Java program.
When i look closely to the LCD I can still see the text that it was showing last, altough its hard so see with the backlight off.

The master brick (1.1) is running version 1.2.4 of its firmware, and the LCD bricklet has firmware version 1.1.0.

3 other bricklets connected to the same master brick still function like they should, so it looks like an isolated LCD problem. When I hit the reset button in brickv the master brick restarts and the LCD work again, only to freeze again after a seemingly random period of time.

I hope this description is informative enough to locate the problem. I'm trying to create a reproducible scenario that triggers the problem.

Kind regards,
Geert Schuring.

General Discussion / IO16 output voltage issue
« on: August 14, 2012, 17:36:40 »
Hello fellows,

I'm measuring around 4.50 volts of output on the 16IO bricklet while the switch on the bricklet reading "3.3V <--> 5V" is switched to "5V".

Switching it to 3.3V results in a perfect 3.30 volts of output, but the 5V is really not even close. Is this a known issue?

Kind regards,
Geert Schuring.
