I wrote a small business preventive maintenance and calibration tracker ( https://pmcal.net ) as a side project. A few manufacturing companies that I have a close relationship with are using it and love it, but I have kind of hit a wall with other growth avenues (Google Ads, organic promotion on the web). I have been thinking of marketing directly to ISO 9001 auditors, because “can you get email reminders” is a quest…

Nice. A calibration tracker is actually on my list of possible future projects :-) I'm surprised to see it here since it's not typical HN fare!

We're increasing the brain's restorative function during sleep. Over the last 4.5 years, we've been developing slow-wave enhancement technology which increases the effectiveness of deep sleep. We've developed the full stack, our own hardware, soft conductive dry (no paste or gel) electrodes, comfortable EEG headband, embedded sleep stage classification and stimulation models, the list goes on and on. We're currently…

Very excited to see this as I’ve been struggling to increase my amount of deep sleep each night. I sleep 7.5 hours, but only get an average of 1 hour of deep sleep. What’s the timeline look like?

So something that I wrote about in a recent blog post[1], we don't increase the amount of TIME in deep sleep. We increase the restorative function (synchronous firing of neurons) without altering sleep time.

We'll be launching a pre-sale once we complete our fit testing (end of Q2 '25) and shipping Q4.

Good use of tech. Hardest thing will be corrosion on the fabric electrodes. Muse S has much to teach if you haven't looked at them yet.

We don't use fabric electrodes, we've developed our own conductive silicone. The other thing to learn from Muse S is that mastoid (over ear) electrodes are nearly impossible. We have comb electrodes similar to dreem.

Though, I don't think corrosion is the issue with Muse S, the electrodes tear as I understand it. Either way, they are not robust enough.

Very interesting, what do you estimate the price will be?

We'll be competitive to the high end of other wearable devices (think Oura/Whoop). We aim to make the starting price affordable by offering a subscription plan, though we are also considering a "full fare" for people who hate subscriptions, but that would be considerably more up front.

A Lottie animation generator that allows to create a Lottie animation from an image and text input.

That sounds really cool. How would you create such a thing?

Some time ago, I began searching for Python-related events and discovered that many PUGs (local Python User Groups) had disappeared sometime around COVID (at least my local PUGs). After analyzing the ones listed on the official Python website, I found only about 18% were still active, with most hosted on Meetup. This makes sense, as maintaining a community requires time and money, which small PUGs don't have. Meetup…

Good work, It looks promising. Perhaps feed it with some group info. If you're expecting people to just show up and list their events I don't think you'll get much traction.

I just finished building a Night Routine manager for me and my wife that help us keep alternating who does the toddler night routine. I needed this because we both have evening activities and trying to figure how to block day for it while keeping the routine fair was hard. https://github.com/Belphemur/night-routine I wanted to build everything from the ground up in Go and have it fully integrated with Google Calendar…

My wife and I alternate and handle conflicts by exception. Meaning, if we have a conflict the other person subs in. I think calendaring things around your home schedule will be hard for the 'things'. Like, a lot of our evening activities are scheduled events that we can't control (concert, theater, etc) or even a group (dad's dinner, etc) and the occasional work stuff. Anyways, I just think it would be hard to plan for the home duties as a conflict and instead we try to sub in for each other and shoot for something that 'feels fair' over time instead of quantitatively fair on a tracker. I'm all for building tools for youself so if you think this would be of use then that's awesome, just thought I'd share my 2 cents on the 'problem space' :)

Also, FWIW, I think I'm the one that is in the deficit of fair although dad's usually get a bad rep in this regard. I end up doing a lot more night time reps because she does frequent girls nights and has multiple friend groups she's trying to stay engaged with and is in a theater group and mahjong group, etc. However, I balance it with my occasional "take an entire day" to myself. Stuff like this is hard to track and why I think it's important to shoot for what 'feels fair' and make sure you talk about it occasionally so nobody suddenly has repressed feelings of inequality.

I recently launched SpiesInDC, a Cold War history subscription service that delivers reproductions of historical documents and speeches, maps, photos, and even coins and stamps to your real mailbox. I have always loved reading about Cold War history, and I'm an avid stamp collector, so I combined the two together and people really seem to love it.

Very interesting. All the best for your thesis. Mine is not nearly as interesting enough.

Thanks! Appreciate it. Your work looks very interesting too, especially in the distributed systems space. Cheers!

I'd love to turn my spectrogram tool into something more of a scientific tool for sound labelling and analysis. Do you use a spectrograph for your project?

Hey thePhytochemist, cool tool! Yes, spectrograms are fundamental for us. Audacity is the classic for quick looks. For systematic analysis and ML inputs, it's mostly programmatic generation via libraries like torch.audio or librosa. Spectrograms are a common ML input, though other representations are being explored.

Enhancing frequenSee for scientific use (labelling/analysis) sounds like a good idea. But I am not sure what is missing from the current tooling. What functionalities were you thinking of adding?
