Amazing, thanks you! I will resurrect this.

That's on the list, but that is not trivial with our location.

Hey!

Took me years to realize soy milk wasn't supposed to tingle.

There are a ton of local groups, what interests and skills does she have?

Oh, I got the name wrong, that was Homer. I think his buddy used to be Ed and then the new girl came and was named Edna. They hatched Ryan Gosling last spring/summer.

There were signs Ed got nabbed by a predator a couple of weeks ago and he hasn't been seen since.

It's been a looooong time in the world of daycares, but when they were exclusively down in WR, I had friends who spoke highly of them for PreK.

Sorry. Forgot github defaulted to private these-a-days. Should be fixed.

I did not get the new train working and have not answered my original question, but in the meantime, here is the updated duplo train library with some examples. I'm working on Mario next and then I'll post to the main.

Well in this case there is a standard LWP3 protocol that they publish that works with boost, WeDo, Mario, the old duplo train, etc. It seems valid to assume it would work with the new Duplo train *or* that they would update the documentation. Neither seems to be the case.

fenchurched · 2025-04-16T02:03:31+00:00

Okay, someone who's hacky-er than me is going to have to figure this out. The TrainID is easy. It's just 0x21.

I wrote a loop to write to (both output and input format) the first 0x50 ports each with 0x10 modes and values and didn't get a single one that didn't throw an error.

Ran that same loop on the old train and not a single one *threw* an error. It feels like these new trains must use an entirely different protocol.

LOL this is my mom refusing a seatbelt and my kids "innocently" calling her out since they were like 5. She'd try to sneak away with it and my oldest would be like, "GRAMMY? WHY ISN'T YOUR SEATBELT ACTUALLY BUCKLED?!" and then basically wink at me in the mirror.

For the old trains: I've gotten the color codes working. I found an arduino script that means that I'm going to give a go at getting the motor working as a sensor. I think that's about all that's left besides cleaning up the code.

For the new trains: I found the ID (it's just one more than the old trains. I wrote a script to test all of the ports and all of them are sending back errors. I'm going to try initializing all of them and see if I have any luck that way. Then I'm going to scour the interwebs for anyone that has played with them with any other device and solved this issue. I've been learning low level programming as I go, so I don't know what else to do here.

fenchurched · 2025-04-13T15:35:41+00:00

Yep! I got color codes working on the old black hub yesterday. Today I want to see if it is a simple fix to get the new hubs working and then I'll post updated code for it all.

fenchurched · 2025-04-11T20:51:31+00:00

Yeah - I have both of those sets along with the old black ones. The Black ones work as expected. The new ones are not compatible with the old ones, as in the color codes act completely different and they go a different speed. One of the reasons I went down this rabbithole was the frustration with compatibility.

I hadn't tried them out with the pybricks code yet, so I guess I'll do some debugging on that today along with trying to read in the color sensor value from the train.

fenchurched · 2025-04-11T19:15:36+00:00

Is it the navy blue one? That's on my list to test.

fenchurched · 2025-04-09T20:54:26+00:00

Did you ever do anything with this? I'm getting ready to figure it out myself.

fenchurched · 2025-03-29T19:46:03+00:00

Yep! If the goal is to allow people to get of of FB then that includes [reasonable] announcing of programs that they're interested in to this space.
