gnome-flashback lock screen bypass with context menu key
Pressing the context menu key at the gnome-flashback lock screen appears to send further input events to the active window underneath, bypassing the lock screen.

SIMPL
simple-captive-lever-escapement-with
The escape wheel now has a locking face, which should help to decouple the escape wheel from the balance wheel during part of the cycle, hopefulling improving accuracy.
There are no banking pins, the idea was that the escape wheel would pull the pallet pin into the root until it couldn't go any deeper, but in practice it doesn't seem to get that far. Maybe the locking face needs a steeper angle.
Ideally I think the slot in the lever would have more free space to allow the balance wheel to swing freely, but for now I'm just using the same lever as before.

MAKIN
making-aluminium-keycaps-on-the-6040-cnc
See here for pngcam: https://github.com/jes/pngcam
This is kind of a crazy way to make these parts, but it works and it was the easiest way for me to do it. Ideally you'd use a 5-axis machine, but even on a 3-axis machine you could do it a lot more efficiently than this.
The cutting tools I have are too small to form the cross in the keycap, so I cut a cylinder out instead and 3d print an insert to make it fit on the switch.
You can see a handful of previous failed attempts still attached to the base material.
At the end I sanded and polished one of the keycaps.

MESHM
meshmill-3d-cam-for-linux-how-to-use-it
Github project: https://github.com/jes/meshmill
AppImage: https://github.com/jes/meshmill/releases/tag/v0.1.1
If you use Linux and are interested in 3D CAM, hopefully this video tempts to you to try out Meshmill. Currently only available for x86_64. If you want to build it for another platform please get in touch and I'll gladly assist.
In hindsight I should have gone for a simpler part and done several iterations before trying to share it. This part is many hours of machining, and it isn't perfect:
- The top surface is gouged because the travel moves sometimes follow the part geometry exactly instead of hopping up to the "rapid Z clearance", & I had zeroed the Z axis too low.
- The plywood flaked off in the bottom right because there were voids in it - I have captured these pieces and intend to glue them back on.
I'm going to cover it in black flocking and build a box around it to store a jug and 4 little drinking cups.

CAT L
cat-laser-test
This is an automatic laser turret to entertain my friend's cat.
I think it sometimes stops moving because the Arduino resets when the servos draw too much current, need to work out what to do about that. Maybe just limit the max. travel speed and min. dwell time?
The knobs are travel speed, dwell time, X range, Y range.
It picks a random position, moves the laser there, waits for the dwell time, and then repeats.

ADVEN
advent-of-code-on-scamp-2021-day-2
In both parts of this problem, I failed to account for integer overflow, which wasted a lot of time.
I also had some trouble today with the editor dropping characters that I type. I'm not completely sure why. I know that it does drop characters if I type too fast, but I don't think I was typing any faster than normal, and I haven't made any changes to the editor since yesterday. If the problem persists I will have to investigate.
