Wow, this is amazing! As a songwriter, the only feature that I’d really need to make it an insta-buy is always-recording audio as well (and then you bookmark it and it only keeps what you sang when you started playing, since obviously audio takes way more storage space). This is probably way out of scope right now, but just adding my feedback. The always-recording piano is brilliant, but I’m not sure how useful it’d be for me without the melodies I’m improvising to go along with it. Honestly, if I wasn’t broke, I’d invest in you building that feature (or entirely separate product?) because it’d be such a gamechanger (and then you could sell it to people who play any instrument).


What kind of quality do you need from the voice recordings? Adding an integrated microphone to that enclosure would be doable but will be limited by quality and where you can place it. I'm asking because I never have a microphone while playing, but I do sing so having a rough idea what I was singing would be nice but not vital.

Seems the ESP32 can to Speex encoding so I guess Chip could integrate this as well. If he manages to earn money on this.


Audio is the next product!


TBH, I've really want a passthrough one-button 8-channel recorder for a long time. It's great for rehearsals of small groups.


Do you have a mailing list?


send an email to chipweinberger@jamcorder.com

I'll add you when I create one.

Appreciate the interest :)


If the problem is psychological trauma, wouldn’t therapy be the obvious solution?


The root cause is psychological, but it's manifested itself in physical changes. She's hyper-sensitive to certain sounds for example, which causes her to not be able to fall asleep, or to abruptly wake up. Mostly low frequency sounds, so hard to block.

But yeah, as I mention in a reply to a sibling comment, she's tried therapy for years without much progress, though recently making some progress on that front.


I know it really sucks and have struggled with it myself for a long time. Two things really worked for me.

Try these: https://www.loopearplugs.com/products/quiet

And at the same time have some calming barely perceptible background noise from a speaker somewhere in the room. White noise, brown noise, lofi, whatever works. Make sure the bedroom has blackout curtains and soft light.

As for cannabis, she doesn't have to smoke it. Appropriate edibles will knock her to sleep. Doesn't have to be a permanent thing either, breaking the cycle and getting good sleep for a few weeks is life changing and may be the start of a virtuous cycle instead.

I recommend both of you enjoy this video together: https://www.youtube.com/watch?v=mK2iXQm4LJs

Good luck!


As someone who was diagnosed with severe ADHD 20 years ago, marijuana makes my brain far more active. If if I have an edible around 5pm, I won’t sleep until 1am (I normally go to sleep by 9/9:30). I constantly want to do things. For me, weed is an upper.

My wife and my girlfriend are both jealous of the effect it has on me. But I’m jealous on the sleep-inducing or calming effect it has on them.

Please don’t assume marijuana affects everyone equally. It may work, but if it doesn’t, your girlfriend will know immediately so you can stop trying it. Ask her how marijuana normally affects her before trying that.


Note I wrote appropriate edibles. There is a variety.

I leave it to you to research a bit further and perhaps try different kinds, with some trial and error you may get lucky yet.


Thanks, much appreciated.

Just saw they very recently approved some canabis oil drops for medicinal use here, so that might also be an option.


I am sensitive to low frequency sounds . The thing that seems to work for me is to play thunderstorm sounds, with isolating earphones. Because this sound has a high degree of randomness across the frequency spectrum, and its spectrum varies randomly over short timescales as well, external noise is masked even if it's still audible - because the brain can easily fit it into the thunderstorm pattern, and so doesn't get triggered by it.

Your milage may vary of course


you say that so flippantly

Phones have completely fucked our posture because they have to be hunched over and our fingers need to contort into unnatural shapes and do repetitive motions. The form factor of being able to stand up straight (or sit back) naturally while computing is the killer feature.


I assure you our posture was already terrible


That’s an interesting take, and I can agree with it. How will you sell this however?


Be the one person who doesn't look like a hunchback endlessly poking at a small tablet - by standing upright and endlessly poking into the space around you.


Basically all the housing in NYC—from the brownstones in Bed-Stuy to the high rises on the Upper East Side—were built during the early 20th century when there was a huge population boom, to provide affordable housing for literally millions of people.

We need to keep doing that. NYC doesn’t need a few thousand more apartments—it needs hundreds of thousands more apartments.


The “problem” is that many (most?) delivery cyclists in NYC aren’t legally allowed to work, so this option would be jeopardizing a large part of their workforce (bad for DoorDash) while also being bad for the workers themselves (who aren’t exactly swimming in job options). I’m not making a value judgement here, just weighing in with a tradeoff to consider.


    many (most?) delivery cyclists in NYC aren’t legally allowed to work
Woah. Are you saying these people are illegal immigrants, or don't have a work visa? I never heard this before. That is a bold claim. Do you have any evidence to share? I tried Googling, but I couldn't find anything.



I feel like maybe one of the causes of apparently such widespread sleep apnea is how most people, as far as I gather, sleep with their windows closed. This is deeply unnatural—we evolved to sleep more or less outside, or at least in a shelter with a steady airflow—so of COURSE sleeping in an unventilated box with stale, stagnant air is going to result in not getting enough air while sleeping. A CPAP machine is basically doing the same thing. This is pure speculation, so I’m curious if anyone else has any perspective on this.


Hmm no the oxygen level is definitely not a problem in most cases, especially considering a sleeping person uses even less of it.

Also a CPAP doesn't increase the amount of oxygen. It just increases the air pressure a bit to keep the airways from collapsing.


This is indeed pure speculation and not how a CPAP works or even sound in thesis.

There is not an oxygen supply problem in a room even if it isn’t actively being ventilated. If there was, you’d have bigger problems. Also plenty of people do have some form of ventilation or air circulation in their homes.

Unless you’re sleeping in a tiny cramped space that is almost fully sealed, this is not an issue.


Sleep apnea and its treatment has nothing to do with whatever work of fiction you’ve invented here.

For cars, it’s actually even more cartoonish than that. Read The Power Broker; auto-centric urban planning is basically entirely the result of Robert Moses’ insane power and influence (in the same way that the reason everyone has smartphones is basically solely because of Steve Jobs).


This is exactly what I’m talking about. That is too cartoonish to be real. I’m not denying that whichever person lobbied or propagandized in whatever way, but it is extremely unlikely to have been the main cause.

A more plausible explanation is that there is an emergent phenomenon where the use of cars drastically reduced the degree of coordination required to develop usable residential property. People are generally lazy when they can be, and so future developers took the easy route of developing land without much regard for things like walkability, because they no longer strictly had to. Prior to cars, if a developer did this, they would not have sold the property. Cars dissolved a natural constraint on property development.


I know it seems too cartoonish to be real, but if you read about Robert Moses, you’ll see that it is shockingly true. He didn’t just lobby and propogandize; he had absolute power over all public works projects in NYC. That’s not a typo or an exaggeration—absolute power, outside of the established system of checks and balances. And he genuinely loved cars, and hated public transit, so his projects were all designed as such. Since his reign, no one has had nearly as much power (some say he was as powerful as Gengis Khan), so it’s been very difficult to reverse the impact of his decisions.

Robert Moses was so influential in reshaping the urban fabric of the US to prioritize cars that everything else is basically a footnote.


It isn't the story itself that I'm saying is cartoonish (though it may be as well). It is jumping from that factually happening to that being the primary cause for the nation's car centric infrastructure and lifestyle. IME an emergent social dynamics explanation is much more likely to be correct than a conspiracy theory most of the time.


It’s not a conspiracy theory. The nation’s car-centic instructure is a direct result of the decisions and actions of Robert Moses, as detailed in The Power Broker.

Not to say that “emergent social dynamics” didn’t play a role, but Moses singlehandedly built most highways in NYC, and influenced hundreds (thousands?) more around the world. And he built them not simply as a response to emerging demand, but because he personally saw cars as the future of transportation.

I suggest reading The Power Broker to learn more about this; I wouldn’t have believed it either before reading it!
