I'm Yiming. WellObserve is a central place for my drawings, paintings, computer programs and other weird stuff.
I recently added newsletter feature on the website, and you guys can subscribe my newsletter and get updates on all sorts of interesting stuff (about one or two e-mails per month).

Added LZMA algorithm to compress our paint canvas data. Files saved with this method have a size reduction of around 50% compared to current PNG method. This feature needs to be turned on manually in the user preference. Please test and report issues.
Data processing routine of huge canvases is improved. Now the program shouldn't crash with very huge canvases (still limited by the memory of your computer).
A new "Stamp" feature is created to "Stamp" the layer on top onto the layer below without actually merging both layers. This feature is useful for merging sketch layers and preserving original sketch at the mean time.
Input device detection logic on Linux is improved, now it should recognize more devices made by more manufacturers and virtual devices coming from xwayland.
Adjusted the feeling of the gouache brush (applicable for pigment canvas).
Additional explanation of what's going on with the electronics part of this model:
Lights and wiring to switches are all verified to work.
Installation of the rear of the device includes a rotation step of the shell on top of the main solenoid. the structure of the wire slot wasn't taking this into account, and due to the tight fit structure, there aren't much extra space for wires to pass through. So the main controls in the rear failed to be connected in the end.
Due to the consideration of the structure integrity, the switch holder was made directly on the shell as a unibody, it's theoretically possible to assemble, but not very easily accessible. Additionally the mode switch requires some instant glue to fix the articulating structure, one side of the mode switch was then accidentally glued in place.
Overall, the appearance is not affected, but it is also very hard to connect the main control. So the circuit part of this project is not continued.
In future projects, fully kinematic (only manually movable structure) designs will be preferred, and if there will be electrified designs in the end, the structure should be designed in a way where wire compartments can be opened after assembling, and switch assemblies should be separate structures that simplifies wiring.
STATUS: Finished with mechanical. Electric components pending.
This is an updated design based on the Hurricane Launcher concept I did last year for the comic and a similar rifle design from this more recent piece. The intention is to make a 3d printable model out of it.
Note: Projectile launching structure is NOT planned or implemented.
