Touch-proof OpenBCI EEG/EMG/ECG enclosure

thingiverse

This is an enclosure for the OpenBCI Cyton and Ganglion biosensing boards. It exposes eight touch-proof connectors (8x1 for the Cyton or 4x2 for the Ganglion) plus a connector for the common reference and for the ground. It comes with an external on/off switch and a micro-USB port for charging the LiPo battery. Although I did not try it, the enclosure should be high enough to mount an additional WiFi field on the board. The complete design includes the following additional components: - OpenBCI [Cyton](https://shop.openbci.com/collections/frontpage/products/cyton-biosensing-board-8-channel) or [Ganglion](https://shop.openbci.com/collections/frontpage/products/pre-order-ganglion-board?variant=13461804483) biosensing board - 10 touch-proof connectors, which I sourced from [Medcat](https://www.medcat.nl/supplies/En/adapters.htm) - 10 [Dupont female jumper cables](https://www.ebay.com/itm/40pcs-Dupont-Wire-Color-Jumper-Cable-2-54mm-1P-1P-Female-Female-For-Arduino/191674518846?epid=5003515415&hash=item2ca0b10d3e:g:X78AAOSwEeFVA-sE:rk:3:pf:0) (not shown on the photos) - [850 mAh LiPo battery](https://www.ebay.com/itm/5-pcs-802540-3-7V-850mAh-Lipo-Polymer-Battery-For-Bluetooth-MP3-MID-DVD-PAD-GPS-/113022961251?hash=item1a50b18663) - [LiPo charger/protector module](https://www.ebay.com/sch/sis.html?_nkw=5x+18650+Lithium+Battery+Charging+%2B+Protection+Circuit+Board+Charger+Module+Z5J0&_id=382315378651&&_trksid=p2057872.m2749.l2658) with micro-USB connector - (optional) two short pieces of 1 mm diameter transparent fiber for the light guides - [on/off switch](https://www.ebay.com/itm/10Pcs-1A-30V-DC-250V-Black-Latching-On-Off-Mini-Torch-Push-Button-Switch-/152823515700?hash=item2394fdca34) - 5 mm LED, connected through a 150 Ohm resistor to the on/off switch - 2.5 mm screws to secure the OpenBCI board and the lid The design is made in Fusion 360 and is fully parametric; so it can be changed if needed. The 1st version that I printed was too low to mount a WiFi shield on top of the Cyton board; the height was increased in version 2. In the 2nd version (as displayed on the photo), the board is in the middle of the enclosure; this causes a lot of stress on the wires from the Dupont header to the touch-proof connectors, which caused some of them to break at the solder joints. In the 3rd and latest version, I rotated the Cyton/Ganglion board 45 degrees and moved it to the corner, which makes connecting the Dupont wires much easier. **Disclaimer:** *This design and the OpenBCI board are not medical devices, nor are they intended for medical diagnosis.*
