Digital Painting On An iPad With Real Brushes

Drawing tablets are a great way to make digital art, and iPads and other tablets are similarly popular in this area. However, they all typically involve using some sort of special stylus for input. [Richard Greene] developed another method, with Light Strokes for the iPad letting one "paint" with real paint brushes instead!

The system uses a Fresnel prism in view of the iPad's camera. This allows the camera to see only the parts of a paint brush, sponge, or other implement, as they make contact with the surface of the prism itself. This is via the principle known as total internal reflection.

Thus, simply wetting a paintbrush, sponge, or even a finger, allows one to paint quite authentically on the surface of the prism. The corresponding Light Strokes app on the iPad turns this into the pretty pixels of your creation. The app also allows one to experiment with all manner of fancy brush effects, too.

The build requires some finesse, with the lamination of the special Fresnel film onto glass using liquid optically clear adhesive, or LOCA. A series of mirrors are then assembled in an enclosure, allowing the iPad to be mounted with the camera having a good view of the glass painting area.

The project takes advantage of a simple physical effect in order to create a great artistic tool. Alternatively, if you prefer to draw directly, consider whipping up your own screen-based drawing tablet. Video after the break.

Firmware Find Hints At Subscription Plan for reMarkable Tablet

We've been keeping a close eye on the development of electronic paper tablets such as the reMarkable for a while now. These large-format devices would be a great way to view schematics and datasheets, and with the right software, could easily become an invaluable digital sidekick. Unfortunately, a troubling discovery made in a beta version of the reMarkable firmware is a strong indication the $400 USD device may be heading down a path that many in this community wouldn't feel comfortable with.

While trying to get a reMarkable tablet running firmware version 2.10.0.295 synced up to self-hosted server using rmfakecloud , Reddit user [dobum] was presented with a very unusual prompt. The tablet displayed several subscription levels, as well as brief description of what each one unlocked. It explained that standard users would get "basic functions only", while the highest tier subscription would unlock an "expanding universe of powerful tools" for the e-paper tablet. In addition, only recently used documents would be synced with the cloud unless you had a paid subscription.

After contacting support about the message, [dobum] received a response that didn't mince words:

At reMarkable, we constantly strive to improve our products and services. In addition to exploring new functionality, reMarkable is also considering new payment models that can support our vision. This includes a subscription-based model.

We want our customers to know that we are grateful for their support and that we always work to make their experience better. If we introduce a subscription model, our existing customers will get this service for free and have access to the full reMarkable experience - even powerful new features we may introduce in the future.

To their credit, at least reMarkable is being upfront by admitting a subscription model is being considered. It also sounds like existing users will be grandfathered in when it goes live, which should come as some comfort to current owners. But for prospective buyers, this could literally change everything. It's bad enough that cloud synchronization of documents would potentially be time-limited, though we'll admit there's some justification in that the company is obviously incurring costs by hosting these files. Limiting features based on subscription tier on the other hand is simply a step too far, especially on a device that the user purchased outright.

We've already seen the first tentative steps towards developing a free and open source operating system for the reMarkable tablet, and this news is only going to redouble the efforts of those who wish to liberate this very promising piece of hardware from the overbearing software it ships with. What worries us is how the company is likely to respond to such projects if they've found themselves in a situation where recurring charges have become necessary to balance the books. We've already seen a motorcycle airbag that will only deploy if the wearer has paid up for the year, so is a tablet that won't let you install additional applications unless you've sprung for the premium membership really that far fetched? Sadly, we all know the answer.

Take Note: An e-Ink Tablet From Pine64

Over the years we've seen a variety of interesting pieces of hardware emerging from the folks at Pine64, so it's always worth a second look when they announce a new product. This time it's the PineNote, a tablet that packs the same Rockchip RK3566 as used in the company's Quartz64 single board computers behind a 10.1″ 1404 x 1872 16-tone greyscale e-Ink screen.

Fitted with 4 GB of LPDDR4 RAM and 128 GB eMMC flash storage, it will feature the same Linux support as previous Pine64 products, with the slight snag of the display driver not yet being complete for 5.xx kernels. They are thus at pains to point out that this is not a ready-to-go consumer device and that early adopters will be expected to write code rather than notes on it.

That last sentence sums up Pine64's offering perfectly, they produce interesting hardware with open-source support, but sometimes the path from hardware release to stable and usable product can be a rocky one. If you're interested in hardcore hacking of an e-Ink tablet, then you may want to be an early adopter. Otherwise, hang back for a while and buy one once some of the bugs have been ironed out. Meanwhile you can see the whole update in the video below; it has a few other things including a nifty keyboard for the PinePhone.

We've mentioned Pine64 a few times over the years, it's worth noting that their products also lie outside the realm of Linux boxen.

Improved Graphics-to-Drawing Tablet Conversion

[Akaki Kuumeri] had an old Wacom Intuos digitizing graphics tablet collecting dust, and figured out how to non-destructively transform it into a drawing tablet. He was inspired by an old Hackaday post of a similar hack, but it required literally hacking a big hole into your Wacom tablet. Not wanting to permanently ruin the Wacom tablet, [Akaki] instead designed a 3D printed frame which he holds in place with a pair of straps. The design files are available on Thingiverse. He names the project, incorrectly as he later points out, WacomOLED (it rhymes with guacamole, we think).

As for the screen, he buys an old third-generation iPad and removes its Retina display panel and the foil backing, which would otherwise block the stylus's connection to the tablet. Toss in an HDMI driver board to connect the display to your computer, and presto -- you have made your own a drawing tablet. Even if you don't need a drawing tablet, [Akaki]'s hack is still interesting, if only to remind us that we can put custom HDMI displays into any project for $65 using this technique.

In the end, [Akaki] notes that unless you already have a non-graphical digitizing tablet laying around, it's probably cheaper to just buy a iPad. This is not [Akaki]'s first go at user input devices -- we wrote about his Smash Brothers game controller and flight controller yoke project last year.
