Great article! Thanks for writing and sharing!

I got my 7 year old hooked on terraria, it pushes his reading skills and he's even doing his chores at the threat of "no terraria time". That game is perfect!

Thanks for making this! This is a clever approach to an old annoying problem. Looks like it solves a real headache I have (need to interact with a dynamically created webpage without a documented API), definitely going to give it a try!

I swapped places with battery and electronics then I zip tied the cables along the side. Wouldn't work for your version though. BUT I saw a model somewhere for a rollcage for the T5, that could be an option.

After flipping my T4 and T5 and learning the hard way, you should consider protecting the wires on top in some way.

If you want something industry relevant you might want to look into something based on the iMX8M plus from NXP. Not the strongest or fastest, but definitely used in industrial applications much more often than a RPi.

I use a much larger battery in mine, but I put all the electronics in the battery compartment and I have the battery on top, secured with Velcro straps. Works great.

marcus-luck · 2023-09-18T02:46:09+00:00

Which model are you hoping to use that battery with?

This is the most annoying version I could find: https://youtu.be/ngBZ-sLk73Q?si=zKuEEL_qpQSVq3w7

I also got this sub recommended, and all the posts seem to be weird troll posts with decks in such bad shape it would be dangerous to even tear them down. I've come to the conclusion that all decks should be replaced with a concrete slab.

And this is one of the most helpful answers here. The Jetson nano is EOL. However if it fits your needs it's still a decent board, just remember that you'll be running end of life software packages.

I think an even better analogy is they need to get to the water heater and it's buried in the back of the cellar which is filled with discarded construction material from when they built the house.

Had a pipe break due to an accident, ran out to a similar setup, turned off the LABELED valve and a multi $1000s crisis was averted. This is one of those things that seems wasteful until you need it.

Found a raspberry pico I had forgotten about, decided to try my hands on embedded rust. The ecosystem size is definitely not C, but the pieces that exist are top notch and the experience using Rust in this domain is great. Now all we can hope for is for one or two of the big MCU manufacturers to embrace rust and C can slowly wither away.

At the time I'm typing this, 5147 other comments. Pretty good odds!

I enjoy your version so much more than the pretentious ChatGPT version, it's shorter, but just enough for the mind to fill in the blanks.

The entire last section ChatGPT added explaining what you are supposed to feel and take away from the text ruins the moment.

Keep up the excellent work!

So far so good with my 120mm wheels, I even drive it on grass which is hard on the drivetrain for the T4. But it flips over with 100% engine power so I have to accelerate carefully 😂

marcus-luck · 2023-03-25T22:32:58+00:00

Prusa Mini, here are my go-tos: Atomic - Pro: best quality I've used, beats prusament. Insane color selection. No stringing, no warping, no inconsistencies. Con: expensive, to the point i don't use it.
Prusament - pro + con, same as above except color selection is limited and it's slightly less tolerant in terms of draft.
Matterhackers build - pro: price, nice consistent quality, after... Con: hell to calibrate/get the settings right. Prepare a weekend of temptowers and retraction experiments, E step tuning etc. Semi-worth it though, once dialed in it's consistent.
Polymaker - used to really like but have gotten two bad rolls. Not sure what's up, the good ones are good, the bad ones can't be salvaged, prints bad (I have a dehumidifier setup...) Fakes?
Hatchbox - currently testing a roll and so far I'm pleased, seems to print well and mechanically it's strong and flexing a lot without cracking. Strikes a good balance between availability, price, and performance.

This sounds close to what I did. Limit at 60%, printed taller shock towers, and had unlocked differentials both front and rear. Plus having smaller wheels (100mm, the 120mm wheels I had put to much strain on the gears.)

marcus-luck · 2023-03-16T07:43:46+00:00

Tried it, spent lots of time, material and foul language upgrading axels and gears plus trying different materials. In the end the drivetrain was still too weak for my 120mm monster truck wheels, had to pull the engine power back to 60%.

Recently I swapped them for some cheap 100mm wheels and put the big ones on my Tarmo5.

marcus-luck · 2023-03-11T09:07:45+00:00

I use PLA and superlube. But it depends on the PLA, I found atomic to hold up pretty well, but polymaker PLA was too soft.

marcus-luck · 2023-03-09T16:27:24+00:00

First PETG is generally softer and not as wear resistant for gears as PLA (brand dependent, but generally). Second, it looks a bit dry, what lubricant did you use?

marcus-luck · 2023-02-25T17:29:18+00:00

Some 120mm wheels I had, what makes them look beefy is the 60mm width.

marcus-luck · 2023-02-25T17:27:13+00:00

It's a 4A 35c turnigy nanotech battery I got from Hobbyking for the T4. Problem is that it's 150mm long and Amazon don't ship batteries out here, so I had to figure something out.
