My sensorboard MYS 1.0beta
-
Got my five kits last week. Soldered the first one this weekend and I must say that I'm really glad I bought them. Very nice layout and easy to understand. The surface mounted resistors/capacitors where a bit tricky with my shaky hands and old greasy glasses but I managed to do it eventually.

@henno Hi and thanks for the feedback.
I am allways interested if anyone see anything that is unclear or needs improvement. -
Are those pads for 0805? I was just wondering if we could all agree on some sort of footprint for future designs. Would help when pre-ordering components ...
Also, I've been reading up on Eagle and I'm seeing a lot of older complaints about the footprint for 0805 resistors. Has this been fixed in newer versions of Eagle or should we use a custom library like the one from Adafruit?

@bjornhallberg yes I am using 0805 component as they seem to be easiest to source and you can still solder them by hand.
I can recomend getting a sortiment kit from ebay with resistors and capasitors for ~10-15$ for experimenting.
In my kit there is only some basic values resistors included 1K, 4,7K and 10K. When using the ADC other values may be needed for dividing input voltages. Maybe that I will add 100K to next batch of kits.
What is people complaining about eagle library files?http://www.sa2avr.se

But I think I will try to find some more commonly used values instead of getting one of those broad kits that only has maybe 20 or 50 of each value and tons of values you'll never use. At least I wont before 0805 also becomes tragically oversized and unfashionable :-)
Quick question, if you've ordered cheapo Ebay components like smd caps and resistors, did you notice anything compared to more expensive name brands?

What is people complaining about eagle library files?If I understood this right, and the issue may have been resolved, the 0805 pads for resistors specifically (?) were a bit cramped, leaving too little space at the ends to apply heat and solder. Made them no easier than 0603 to some people, at least according to how Eagle drew them. But I guess that also depends on your specific soldering technique.

I also like to have 5 boards... Please tell me how to order and how you like the payment...
Thnx for the great work!
-
Would like 5 too, if still available.
-
I am soon out of boards to sell. Only got about 15 boards left.
ping @twisted if you still need boards please read your pm.
Because of that have I started ordering components for another batch of boards.
I have also started developing a LED pwm daugtherboard for easy dimming of led strips.
More info on that when first prototype is ready. -
I have ordered 300 more boards yesterday.
As soon as they arrive I hope to have my online ordering page ready.
I also going to sell the boards without components for you that want to source components yourself or are soldering everything directly on board without sockets.
Stay tuned. -
Yes when I stop providing the boards. After that am I going to release it as open hardware.
For now am I selling the boards and the money I making on them are spent on developing new boards. -

I think it would be a good idea to release the design files right now, as it allows people to get a detailed insight in your design and what they'll receive when ordering.
Furthermore every body can help improve the design, but you'll keep in charge of course.
The whole idea about MySensors (both software and hardware) is to be open so everybody will benefit in the long run. -
I now have 300 boards on my desk and have set up an online ordering system on my page http://www.sa2avr.se/mys-1-1/
After a discussion with @hek have I also released the board files for mys 1.1 on my page.
