I have depression. And just because I have depression does not mean I'm any less lovable, investable, or any -able. A part of me refuses to die, and this part knows I can turn my pain into something positive for others. This is my creed, purpose, momentum, gravity, and rope

My own brainwave recorded by my own @neurosity hardware. It’s my first tattoo! I’ve wanted this tattoo for years but it had to be recorded with hardware I built. I’m proud. The brainwave was eyes closed focusing on the present.

I moved back into my parents basement. couldn’t risk staying in NYC with my asthma. I moved everything needed to build+reflow PCBs, compile embedded Linux builds with 16-core PC, and run @neurosity from my Mac Book Pro.

Demand is growing faster than churn @neurosity I think it’s right to give people the option to cancel, versus forcing them to buy a product outright immediately. I see churn, aka membership cancels, as a form of feedback we can measure. I saw a customer join the membership

Fuming about teenage suicide 😡 this is the group I want to help so bad. Just lost an amazing family friend and I feel so helpless. This is the group I think of when people ask me why I am running neurosity. As someone who almost lost the battle, as someone who dreams of helping.

@moizali This opinion is unpopular most likely because it’s discriminatory and likely due to the effects of systemic racism. There is a strong correlation between student performance on the SAT and race/ethnicity, highest level of parental education, and family income. Source:.

@WesLouis_, Apoorva, and I making the one-of-a-kind white crown for @Grimezsz last month. Did you know that white is actually a combination of all colors in the color spectrum? 🧐. It’s fitting, after all – she’s the queen of eclectic, electronic, experimental dream pop 🗯️

Thanks to everyone who keeps buying Crowns! We sold more Crowns last month than we had in inventory to start the month, so we had to keep manufacturing to keep up with demand throughout the month. We hired an operations teammate to speed up production to stay ahead of demand.

This is where the @neurosity magic happens. The monitor on the right is for most of my computer work (programming, PCB design, administrative) and the left monitor and keyboard support building/testing/debugging hardware. There is a full hardware lab to the left out of picture.

It's Neurosity's 3rd birthday! 3 years ago I had a quad-core computer with a custom brain imaging chip on the ugliest thing you could imagine with no operating system. Alex and I teamed up, and with his code, theories, and design we made the Crown

"But Farza, I'm a hardware startup". What I've learned from hardware founders at @fdotinc is that you can 100% build prototypes + get users fast. @andrewjaykeller shipped an early version of the @neurosity on a pair of old Bose headphones as the base!!.

I want the phrase to be “Life/Work” instead of “Work/Life” balance. Can we put consideration for life before work?. Last weekend I went hiking to Mount Tam with a bunch of founders and friends from @fdotinc who are helping me pursue balanced life; I’m very grateful for them!

Now open to the public, rent a Crown for $100/month. . For researchers and app developers, we've eliminated spending $20K on 20 devices for a month of research! That now costs $2K and any problems, we'll overnight a replacement, and ask questions later.

@LaraNerdsom @ladyleet @reactjs We heavily use #RxJS at @neurosity due to the fact that the brain is a continuous stream of events. We have a whole library written in RxJS for brainwave processing called eeg-pipes and we use RxJS in a lot of other places too.
