System Assembly Troubleshooting / Soldering Coaxial Cable to CMOS Imaging Sensor PCB

« on: May 12, 2017, 10:07:35 PM »

For the life of me, I can't solder the coax to the CMOS PCB without a short (if I even get it on in the first place). An tips for this? I have v3.2, with the 2 holes instead of 5 (and much less room to work with). Also, the CMOS PCB I'm working with has a short between signal and ground without any visible solder or anything on it, maybe because I heated it over and over. Is this PCB toast or is there hope to fix it?

Optics / GRIN lenses from Inscopix

Edit: I didn't realize we could buy 1.8 mm GRIN lenses from Edmund Optics. But I'll leave this here to let people know that Inscopix and Grintech (who I first emailed) will not sell the objective lens.

I emailed Inscopix for purchasing GRIN lenses, and I was surprised when they told me the largest diameter lens they sell is 1.0 mm. After a couple more emails, I got this message:

"Thanks for your reply. We proudly provide the neuroscience community with fully assembled nVista systems for in-vivo calcium imaging. We do not make any components of our technology, including the objective lens, available for individual resale whether through Inscopix directly or through Grintech.

Thank you for understanding and please let me know if I can help you with any of the relay lenses.

Best,
Katrina"

General Discussion / Upcoming workshop

« on: January 03, 2017, 09:45:55 PM »

Hi,

I'm attending the upcoming workshop in January, and I just have a couple questions.

1. Apart from reading through the wiki site, is there anything else that is critical to do to prepare for the workshop?
2. Is programming experience required for set-up and use of the miniscope system? I do not have any, but I'm willing to learn what is required.
3. When is the current group order for PCB components being sent out?

Thanks,
Casey
