Show HN: Hacker Newspaper – Yet another HN front end optimized for mobile
https://hackernews.paperd.ink/
I was trying to find better content (doom) scrolling sources (quit Instagram, YouTube, etc). HN was great but I couldn't read properly on my phone hence I built Hacker Newspaper -- a mobile first HN reader.Key things: - Mobile-first, newspaper-style UI - Tap goes to comments, not article - Nested threads that don't get crushed on small screensStill WIP, would love some feedback. Thanks!

Thanks Abhishek! It's a pleasant surprise to see you again and remember about needgap.

Sorry I don't get it. Do you mean people spend huge amounts of money to promote the product? And thanks! Just wanted to make a minimum lovable product.

If only! Maybe when the patents finally expire, it'll take off like 3D printing did.

They use recycled kindles hence the color and touchscreen I guess.

As commented by another user, we were selling for 89$ with free 3d printed enclosure and free shipping. However, the size of screen is smaller.

That seems to be one strategy. For us, we had about 500 people who filled our very first user research form and we kept a target of minimum 300 orders to be able to manufacture the units and at least break even. Turns out, not even half of the 500 folks read our crowdfunding launch email. We didn't have any money to spend on paid promotion. So we then did everything, from posting on relevant social media channels to trying to get articles written about us by blogs to cold emailing people who I thought would like the product - and one of them did who offered us the FOSSUnited grant! I guess whatever works best for your product/campaign.

(OP here) Update: We sold out the first batch of paperd.ink! Thanks to each one of our supporters, we managed to pull this off because of you. As next step, we would love to talk with the users once they have paperd.ink in their hands. And for those who missed out, you can drop your emails or keep a track of our social media to be updated. Thanks again!
PS: I will reply to the pending comments shortly. Sorry things have been busy here (our website crashed twice in the last 5 hours).

Looks confusing imo. Exact dimensions are mentioned here though https://docs.paperd.ink/docs/hardware/hardware/#dimensions

Thanks! One unit will have a devboard (PCB) with e-paper display connected on the front side. And there's also the enclosure set which has a front panel, back panel, 4 buttons and 2 stands (check this to get a better idea https://docs.paperd.ink/docs/3d-files/assembly/). We don't send assembled enclosure with devboard, that is DIY.

Sure thing I'll add in FAQ soon. If you do not want to solder then https://www.amazon.com/dp/B09FLDCJCB is a good option as the connector is directly compatible with paperd.ink. But it has a lower capacity.
For a higher capacity, we recommend https://www.adafruit.com/product/258 but you will have to cut and swap the connections since the connector is of the opposite polarity.
Hope that helps!

Fill in the first two entries for Title and URL and have "Show HN: " in the beginning of the title, that should work (or Show HN submissions, not sure about other kinds of posts.

Fair. Personally I am not a big fan of touch because of the latency in response and paperd.ink is open-source. PineNote is a whole different beast though.
Re:Show HN: Paperd.ink – an open-source e-paper development board

It does not. Touch screen e-paper displays (like Kindles) are too expensive, consume significantly more power and have a noticeable lag in the response when you try to use them. paperd.ink is more of an output device.

Thanks! We're selling the dev board for 89USD along with a free 3d printed enclosure and free shipping.

Indeed. Fun fact: e-ink is the name of the brand whereas e-paper display is the general term.
Show HN: Paperd.ink – an open-source e-paper development board
paperd.ink (https://paperd.ink) is an open-source e-paper development board. We wanted to build something with e-paper given its low-power nature and beautiful, high contrast display which complements your environment and is easy on the eye. Thus, we started working on something to be developed along the lines of Arduino, Raspberry Pi’s open-source ecosystem.paperd.ink has a 4.2” e-paper...

Oh no need to desolder, just disable some MOSFETs usings GPIOs in the code. The MOSFETs enable/disable parts of the circuit like SD card, e-paper, battery monitoring, etc

Sure you can. We wanted something like this for ourselves and thought of sharing it with the world. Thankfully some of them liked it too
