RE:Creation - Gadgeteer Capacitive 5" LCD by dominik38 on Jul 15, 2014 at 2:30am

I comprehend your point. Hard to intermediate way for your situation Banging Head
How about only selling the PCBs? Would be a Win-WIn situation for everyone? Additionally it makes shipping easier.

Edit: Or a version with everything on it, only without the display? So one can get the display directly a the supplier and only has to connect it to the socket?

I know, I know..I only need a few...will take a closer look about the complexity of the driver. I think there are many code examples which could be adapted

RE:Bluetooth Module Eagle Files by dominik38 on Jul 14, 2014 at 2:53pm

Okay thanks for the info!
I think I have to build one =/

RE:Bluetooth Module Eagle Files by dominik38 on Jul 14, 2014 at 2:36pm

@ RoSchmi - are you sure?

I checked following:

1) comment on DX.com for Bluetooth module:
http://club.dx.com/reviews/text/80711/425931
2) the guy links that site: http://www.samenkopen.net/action_product/46212/778874

3) when I compare the pins from that site with the ones from the module page:
http://www.ghielectronics.com/downloads/schematic/Bluetooth_Module_SCH.pdf

It seems to be the same?

RE:Bluetooth Module Eagle Files by dominik38 on Jul 14, 2014 at 1:40pm

As far as I know Justins module was 40$?
Little bit too expensive for that project.
And I have HC-05 modules here, so it would be a good opportunity to use them Cheesy

Combination of learning and sharing, plus a little gadget money. In that sense, it's been successful for me.

100% agreement!

Bluetooth Module Eagle Files by dominik38 on Jul 14, 2014 at 12:33pm

Hey,

I need some cheap Bluetooth modules, and wanted to produce a few PCBs of the discontinued bluetooth module (https://www.ghielectronics.com/catalog/product/312 )

Could GHI be so kind to share the eagle files? It would save me a lot of time Smiley

Another question: What Bluetooth module is that? HC-05 or HC-06?

Cheers,
Dominik

I sold a few modules, but the income didn't cover the expenditures. If you set the price too high, there is no interrest for your module. So I set the price as low as I can, so that it just covers the material costs and a little more to buy parts for new modules.
If I make a mistake e.g in the layout, and I have to order new PCBs, then I have a big minus. So all in all it's just a hobby, and I don't try to get rich from it.

It would be a nice second income if the orders were >100 (although a lot of work too), so I think that should be a goal for us..to spread the word of Gadgeteer! Smiley

Will add some more soon

Architect says:

Shouldn't be hard. Justin alone can cover the whole 10.
I put one listing and 2-3 more are coming.

Do we need 10 products, or 10 different persons each with minimum 1 product?

Simon from Vilnius says:
I think we need 10 people listing something to unlock the market...

Uh..that makes it more difficult Huh

RE:Modlab Site by dominik38 on Jul 7, 2014 at 9:14am

@ransomhall

Very good idea!

I'm also interrested in a nRF24L01+ module, as I have a few from dx here and want to build a cheap network.

My thoughts are:

- OLED Module (SSD1306) (I saw that Justin already built one!)
- Vibration Detection Module (Sensolute mvs 060802)
- Memory Display (Sharp LS013B4DN04)
- GadgeteerCable Tester --> already under construction

Anyone interrested in some of the modules?
The Memory Display looks very interresting as it consumes very little power!

RE:Modlab Site by dominik38 on Jul 7, 2014 at 1:04am

I'm in! So only 8 left Cheesy

nice one.. I like Smiley

RE:Getting wrong value from sensor by dominik38 on Jun 27, 2014 at 7:30am

I try that! thx

RE:Getting wrong value from sensor by dominik38 on Jun 27, 2014 at 3:34am

No ideas? Sad

RE:Getting wrong value from sensor by dominik38 on Jun 21, 2014 at 8:19am

According to the datasheet, the conversiontime is 240ms.

Have tried different cable lengths, from 10cm to 20cm. But shorter cable has no positive effect.

Getting wrong value from sensor by dominik38 on Jun 20, 2014 at 8:44am

Hey guys,

I'm having a strange issue with my Temp7410 module and don't know where to start debugging.

Following situation:

I request the temperature from the sensor every second.

Everything works fine, but
-) when I touch the sensor IC or
-) bend a cable or
-) blow the sensor (smoothly with my mouth)

I sometimes get '0' as return value.

I checked the solder joints, desoldered everything and soldered it again,
changed the cables, and decreased I2C clock frequency from 400kHz to 100kHz.

Last night I left it alone in the living room, capturing the temperature, and there was not a single '0' reading.

I built a second circle on a breadboard, to see if it's a layout issue. But same behavior.

So I expect it to be a problem with my driver, but I'm not doing anything else than reading a register from the sensor every second. I don't know what could be wrong there.

You can find the driver here:
https://github.com/dominik38/Temp7410

Additionally I have attached an image of the circuit.

Does anyone had a similar issue? Or could give me a hint where to start?

Cheers,
Dominik

RE:Creation - Button Extender by dominik38 on May 24, 2014 at 4:31pm

hvelo says:

I would have thought if one pin was interrupt capable, then at least one of the buttons would have fired these events.

According to this:
I just implemented the interrupt code für Button0 (Pin3 = interrupt capable), but I didn't get good results for it when I push the button for a very short period. So I won't implement that code in future releases.

Cheers
Dominik
