Title: Exact dimensions of the electrodes and the CAD model
Post by: ellecieffe on August 24, 2013, 04:11:01 PM
Hi to all,
where can I find the exact dimensions of the electrodes and the CAD model of the mechanical part ?

Hi guys

Are these the right dimensions?

Can anybody send me some pics of the electrodes? I need to know the dimensions of the cable mount on the top, please.

:D

Hey there!

The picture with the dimensions you have embedded in your post is TOTALLY not right. The dimensions of the box are L x W x H: 88mm x 50mm x (22-25)mm.

There are schematics for both the passive and the active electordes. Did you check them: https://www.olimex.com/Products/EEG/Electrodes/EEG-PE/resources/MOD-EEG-PE_sch.pdf (https://www.olimex.com/Products/EEG/Electrodes/EEG-PE/resources/MOD-EEG-PE_sch.pdf) ;https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/resources/EEG-AE.pdf (https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/resources/EEG-AE.pdf)?

mmm ???

Sorry but I mean the physical dimensions of the electrodes, not of the box.
From the schematic I can not see them, I extracted the pic from  eagle files

Hmmm, sorry I missed "the electrodes" part. My bad. Unfortunately, we don't have mechanical and 3D models of our boards. The dimensions for the electrodes is overall correct (+/- 3%). We also use the dimension tool in newer versions of Eagle. By the way you have used the bottom layer for the dimensions, you might want to use layer "47  Measures" - please check my picture: http://i.imgur.com/HC0kcUT.png (http://i.imgur.com/HC0kcUT.png). We also print the board files on a piece of paper to visualize the outer dimensions and the electronic components placement.

Best regards,
