Re: eagle

Hi hosam, mattylad has given a really helpful option there. That could be the best way to go about this actually. On the other hand. Eagle saves versions of your schematics. You could take the latest *.s# file and rename to change the extension to .sch Modify the schematic to be exactly the same as ...

Re: Thingdev + relay

Hello,
Try using this instead: https://www.sparkfun.com/products/14236

Be careful when dealing with AC. It's dangerous.

Cheers

Re: Arduino With RFID

Hi,
I think you need to double check the connections and make sure they are right and not loose.
If that test passes, try different code like paulvha suggested.

All the best.

Re: Weather Station Errors.

Hi David, I think the MPL3115 library was not installed well or not installed. Go to https://github.com/sparkfun/MPL3115A2_Breakout/tree/V_H1.1_L1.2.0/Libraries/Arduino and download the repo as a zip file. Open arduino IDE, go to include, then mamage libraries, then choose add zip files. Navigate to...

Re: Question from a newbie about switches

Hi Harley, To help out Danv, if using a DPST, connect the common line to your circuit and eitger of the poles to 12V or 24V. If using a DPDT, the connection is still the same but the switch will have 3 stops when toggled instead of two. The middle (often) stop is for off and either side is 12V or 24...

Re: Gerber files for board greater than 2 layers

8 layers is really impressive for a second PCB. Well, I haven't seen any ready made Eagle Gerber Generator files for anything higher than 4 layers. But what I do know is that you can copy the 4 layer Gerber Gen file and add the other fpur layers. In the additional 4 tabs, You will need to include th...

Re: Problems Autorouting pcb with Ver. 7.7.0

Hi KevinRoach , The Autoraouter in Eagle will not give you the same result if the components are layout out differently from the original. In 7.7, the autorouter may have been updated therefore would work better. Your DRU files may also be different from the original, this makes Eagle route the boar...

Re: High Speed PCB Design

Hi Williamhawk , I'll try to answer some of your questions. 4. As Mattylad mentioned, SMD parts have very many advantages over through type components. I'd add one more advantage, when you get to high frequencies like you are, using through type components creates tiny pointy stubs on the opposite s...

Re: Beginner PCB design for LED clock

Hi ajk48n, I took a look at your PCB specifically to see what you did with the decoupling capacitors. An easy to remember rule of thumb while laying down decoupling capacitors is to always put them as close as possible to the pin they feed power to. Then when laying the power trace, let the line go ...
