Not interested here, because I don’t think this tech of SonarPen is good for artists. From what I could see on the demo at this time code the device tip is bulky, the line is lagging hard, the variation of pressure have steps in them (and there is a cord to the stylus?).
From what I see, you can’t do quick gesture or sketch because of lag, nor line-art because of precision. So, a device like that feels to me like a gadget that make digital drawing hard.
Anyway, I salute the ingeniosity of Elton to make a compatibility bridge with this type of hardware to Krita, the generosity to share the source code and post here builds and the idea of porting hardware affordable to Krita.
Just how did you find this video? it is not listed anymore. I want to give that fellow who comented there the info, that he has to use a special build of krita. I feel so bad for him not beeing able to use krita! I would like to know the specs of that tablet, to know if it is the pen or the tablet.
The video that @Deevad refered to was our very first successful run of SonarPen on Krita. It was running on Krita v5.2.2 using a Samsung Galaxy Tab A7 Lite with a Mediatek MT8768T Helio P22T cpu. The Samsung Galaxy Tab A7 Lite was a give away device from the mobile network for signing up a mobile plan. It was a painfully slow device but that’s what we had handy in the office at that moment. Also we believe if a super budget device can run at this performance, the app will run great on Android with better spec.
To show how slow the Galaxy Tab A7 Lite is, at the splash screen, we have to speed up 1000% to avoid a 30-40 seconds load time. There is no speed up or other alternation at the drawing footage, which gives the illusion of SonarPen is slow and laggy. I am very sorry that no explaination was given when I posted the original video, and caused confussion.
The goal of the SonarPen was to help promotion digital drawing at the lowest cost. There is no doubt stylus bundled by the device, like the S-Pen or Apple Pencil gives the best performace. But such setup also comes with a much higher price tag. I too agree the disc nib is not the best nib for drawing, however that keeps the cost down. We believe Krita has a similar mission (to promote digital art), that’s why we hired programmers to port the SDK to C++ to work with Krita.
SonarPen has been used by over 350,000 users around the world. I am sure the cable must have caused inconvenience at some point, but that doesn’t stop them from creating beautiful drawings. Here are some drawings posted by SoanrPen users using other drawing apps. SonarPen 2 drawing stylus (@mysonarpen) • Instagram photos and videos
I hope my explaination is able to remove some doubtd that @Deevad has.
I just found out, that there is a sonarpen2 with pointy tip, tilt detection and palm rejection out now. Does this pen also work with android and your krita version?
Thank you for the extra info. The video on the Instagram profile about the (upcoming?) SonarPen v2 looks like it address a lot of issue, no lag on the trailer, and a precise brush tip. I’ll keep an eyes on this tech for sure, maybe one day I’ll get my hands on it. I have a spare Galaxy Pro Tab here that has no stylus and run on Debian 12, used in the living room as a portable media consulting devices (photos, videos, etc); I wonder if this type of stylus are supported on GNU/Linux, have you got info about them @elton ? (sorry if you already wrote it somewhere in this long thread)
