Is there any general info about the price structure of the premium PCB service? I don't want to send files for quotes because at this time I am only thinking whether panelizing makes sense.
How about panelized 100mm x 100mm purple for example, everything else like the standard service?

Does anyone know of any special tricks needed to create a SeedStudio FusionPCB account? I've been trying most of the afternoon, and once I've completed the page and pressed Register it simply hangs, with no further updates or messages.
Thanks - Will

First, since this says 14.8V that means I'll need to power it through a transistor from the Arduino, right? What about the P2N2222AG included in the ARDX kit? I think that has a high enough V to support it.
Second, does that mean I should join two 9V batteries in series to drive the solenoid? Or is that too much (18V)? Should I get a battery that is more specific?
Finally, I'll include a diode as well since it has a kickback when the solenoid is turned off. Does the one included in the ARDX kit work for that (1N4001)? How would I figure out that it did?
Thanks!

No problem. Using USB for power only provides 5 volts to the Uno and shield(s). The relay shield I have required power to be supplied to the Vin pin on the Arduino for it to operate. There should be a power jack on the Uno where a power adapter can be connected.

Thanks for you response. Can you explain me more please. I connected the arduino uno in my PC using the usb cable.
In your response, you mean that I have to connect also the relay shield in power. What pin should I use to connect it please? Have any documentations to help me? I am very very pressed.

I am doing a project for controlling a 4 light sources. I need to turn on a light source each 5 second. For this, I bought an arduino uno and relay shield v2.0.
1) I Stacked the Relay Shield onto Arduino. And I connected Arduino to PC using a USB cable.
2) I connected each light source like this:
a) The positive wire pass throw the COM and NO before to be connected to battery. b) The negative wire pass is connected directly to the battery. c) I configure the follwing pin to control four relays:
pin 7 -> relay 1 pin 6 -> relay 2 pin 5 -> relay 3 pin 4-> relay 4 I developed my program like this:
I remark that the leds corresponding to relays work correctly turn on for each 5 seconds. But the relays are not clicked (no noise). Besides, the light sources are not worked (it is turn off ). Therefore, I changed the light source connection such that the positive wire of each light source is connected between the NO and COM. In this case, the lights sources are worked. But, the problem is : light sources are always turn on even i changed the LOW and HIGH status of pins. What is the problem. any help please!

Hi all, I managed to get my DSO Quad sorted. Here is how I did it:- 1. I connected a USB to Serial board to the UART at CN7 on the Printed Circuit Board. 2. Mine created a serial port at COM1. 3. I used the stsw-mcu005.zip from the STMicroelectronics web site. It is a Windows GUI for flashing the CPU. 4. FIRSTLY I downloaded my existing firmware from the DSO Quad and saved it. 5. I then tried a variety of Bootloader .bin files and ended up with the need to put a Licence code in each time, but at last I was able to see and use the DFU Mode 6. I then tried a variety of SYS.Hex and APP.Hex but had a problem with the top line menu in scope mode not formed correctly. 7. I flashed my previous firmware back into the quad (see step 4). 8. Hey presto everything now works properly again.
I hope this helps anyone else with a similar problem.

Hi. I have the same problem. the 'Vertual DFU USB Drive' appears for perhaps 1 - 2 seconds and then disappears. There is no drive appearance to format or do anything with.

Hi, I have the same problem. It appears on my PC (as 'DFU V3_12_C'), but I cannot copy anything to it. If I right-click on it, I can get basic properties. If I just switch it on (no >|| key) it appears on my PC as 'DSO' and I can copy to it. I have tried Windows 7 and Windows XP. Tried different USB cables and ports.
Please help

OK, I feel a bit silly now! But as I can see others might get bit by the same oversight, here's what I did wrong...
There is nothing wrong with the Yun or my code, I have been using Grove from Seeed Studio as a way of rapidly prototyping combinations of sensor for different applications. All great and fine, but I2C is not on the same pins on the Yun!
The Grove Base Shield I2C plugs can not be used when you use this shield with the Yun, though other analog and digital pins are fine. I wired a Grove I2C Hub to pins 2 (sda) and 3 (scl) and everything works great.
I have two separate systems with the following setup: a Grove shield on an Arduino Yun with an OLED Display 128*64 in the first I2C plug (the one nearest the analog plugs). Here is the problem: when I load up the "OLED_Hello_World" example nothing happens. The screens on both are dark.
These are new Yuns and seem to be working fine otherwise. I put a Grove Temp/Humidity Pro sensor on A0 and that worked great. The OLED displays don't. I tried one of the OLED displays on a Xadow, and it works fine there, so I don't think there is anything wrong with the OLED hardware.
Any idea what is going on?
The example code:
