Very cool! I've designed a lot of Hilbert Curve marble tracks, using OpenSCAD and python


Small world, I opted for a Gosper curve myself, but when it got too big, cut out specific pieces and connected those.

It gives everything a uniform look while allowing to fill the space in a different way.


That sounds super interesting, do you have a link?


Not the person you asked, but look up "Hilbert Curve" on Thingiverse, Printables, or Thangs and I bet you'll find somebody who uploaded a marble run with more information for you.


Yeah if there's more interest I can publish the GH and onshape! I just need to sanity check that I didn't leave any keys in it or anything...


Blog post about my mechanical design, robot math, stress testing, and competition for "Mech Warfare", a small airsoft-only battlebots competition this summer


OP getting this robot working in about 3 months was insanely impressive.

what is the no gimmicks rule?


I can't quote it offhand, but it's stuff like:

- Don't stick your camera on an arm and poke it around corners to see the opponent

- No detachable parts? It's more nuanced than this. Not leaving "mines" I think is a case of this.

Basically there's a few goals to the rules (this has been an on and off competition for about 15 years now): keep the spirit of "pilots in giant mech robots" (loosely 90s era stuff), and homogenize the competition slightly for competitiveness.

Melee is still allowed! If you walk into the other robot and trigger one of their 4 score panels, that still counts.

It's a hard competition to prep for. Numerous bespoke HW subsystems, software, budgets that grow quickly with the size/weight of your bot... and being reliable.


Excellent write-up. This is one of those side projects that has been on my list since forever and this seems about the level of accomplishment and tech that is within reach. Good effort! I'm looking forward to further refinements.


Thanks!

How else m I going to geotarget you with ads? /s


I thought about this, but I've seen several times where the signs say that the train is running late, but it's actually there and leaves perfectly on time!

The schedule has been much more reliable since the electrification


Thanks :)


bullet trains should be displayed in red, but I haven't tested it yet at the right time and I've been too lazy to write tests with mocked time / gps :)


Looking at it now and the bullet has black text


"22nd st" shows up separately


Made this while procrastinating some actual work, in an effort to get some more dopamine from crossing off todos.

Completing an item gets you a confetti explosion, a satisfying ding, and shakes the item.

Section headers (starting with "#") are even more exciting to cross off


Also there's no backend - everything is in localStorage
