I'm a few hours from Gdl, but I'd rather not get more specific than that. Guadalajara is nice! I kinda wanna move there! You ever been?

I understand- and yea, got a little place down thereabouts.  Spent a few summers there thus far.  Love it :heart:

That's super cool. Good luck with that! I don't really know much about even simple robotics(which is bad...because my dad always puts those cute little sets in my stocking at christmas and I am a terrible person for never doing them :facepalm:) but I know compatibility issues can be a real bitch with stuff like raspberry pi, so fingers crossed you can work it all out without frankensteining it. Looks like you've got some fun troubleshooting ahead though lol.


Yeah I got the original Mindstorms set as a present as a teenager and did not do anything that cool with it. More recently someone gave me a couple Nvidia GPUs hoping I would figure out some stuff in Tensorflow. I find gifts with big expectations a lot of pressure.

I took an embedded systems course a few years ago that used the previous generation of Mindstorms  (and other projects that ran as simulations) and always wanted to get back into it. One cool concept that predates computers is the PID (proportional integral derivative) controller. Apparently there were mechanical implementations for getting big ships to follow a desired heading without a helmsman having to manually correct for external factors.

The lab we did on it was a simulation of an inverted pendulum, which pretty much is the same setup as a Segway or something (if it was on rails). The only simulated input detects the angle of the upper part, and the output is motor power. The proportional term is the raw angle, you calculate rate of change of the angle for the derivative, and the integral is the average of the last so many readings. For each of those 3 factors you work out how much it diverges from a target value you specify (e.g the angle should be vertical, its rate of change should be zero, and the running average of the angle should be vertical.) For each of those error terms, you determine by experimentation a coefficient for its contribution to motor power, and sum the three contribution terms. Don't know if that was the clearest explanation, but the TLDR is it's not all that complex to set up but the results are impressive when you get those 3 coefficients tuned nicely.

Would like to try making a Segway type thing that balances itself but this set did not come with the accelerometer sensor you would need.

For Mexico it's crime. I had trouble sleeping last time I visited Canada, because we stayed in a rental house and the rooms had glass windows with no bars at street level. That shit's unthinkable here, you only get bar free windows past the first floor in good neighborhoods and the second or third in bad ones.



My parents had to put bars on the basement windows at our place when I was growing up, kept getting burgled. Also metal reinforcing on the back door. The house is on a corner with a bus stop, and not all that far from some rougher areas. But the rough areas are not really that rough as far as violent crime. Surprisingly the roughest places in Canada are not the big cities but out in the sticks.

I got this Lego Mindstorms robotics set recently and I found out yesterday you can put Linux on the controller brick. So I got that set up and I can SSH into it, but the example programs are not finding the motors etc. Not sure if I screwed up a step setting it up, might have to start from scratch. But it looks like it should be cool when it works. Apparently things like cameras will work in the USB port like normal if they would otherwise work with Linux. The wifi adapter I had did not work under the original Lego firmware and now I can use it.


Dope! You got any pics? I've got a couple Raspberry Pi laying around I haven't done much with, I've been wanting to set up a timelapse camera or a dashcam, the hard part for the dascam would be the hard drive, since a micro SD card will eventually die from so many writes and having a portable harddrive sitting on my dashboard is gonna get my window smashed. A contractor from my last job  made his own gimbal with arduino and milled steel and it was dope!


Yeah I have a couple of RPis (A+ and Zero, both pretty much the same thing under the hood) that I never did anything too cool with like using the I/O pins or a camera or anything. Somewhere in the house I have a 5" HDMI LCD that I got for them.

Aren't accelerometers super cheap nowadays though?

I never really felt unsafe in Canada, even the sketchiest of lighting over there is much better than what we have here. My sister laughed at some California students calling a normal (to us) van sketchy AF and they were worried they were gonna get kidnapped or something, just because the van had some wear and tear on it :lol:

I've always sucked at hardware, even simple things I can't get to work. I wanna get back into it, but simple projects don't seem challenging enough and more complex ones seem out of my league. Maybe I should just get off my ass and try.

In other news, I'm really happy with how my first successful loph graft is looking, it's tiny but growing great despite the tiny stock:

I pretty much too all the core classes for both majors.

I like that stuff.

I did about half a CS degree and dropped out. I find it enjoyable but some of the requirements were too onerous for me at the time (math, stats, operating systems). I pretty much took whatever courses I thought would be fun. Embedded systems, computer graphics (ray tracing type stuff), artificial intelligence, security, etc.

Ninja cat nice cacti! A little skinny but I'm sure it will thicken  up in time.

Been dabbing budder lately,  it is quickly becoming my favorite cannabis extract. Has a similar effect to black hash but stronger.

There is a marathon of Cosmos on right now so that's nice! Tho going to play drums soon probably throws in Ill Communication and play along :awehigh:

I have a CS degree, and I liked the first half but hated the second half of the course. Mainly pushed through it because I liked the work and I thought it would be tough to get a job without a degree.

Thanks Sonic! That reminds me, I've got some hash laying around I wanna vape. Gonna get blasteeeeddd.

Just waking my lazy ass up.

What’s up friends.

Gonna get some breakfast in me then we heading off to Lilys parents to drop off the brats for a few days.

Lily has the weekend off so the three of us are gonna hit up the Denver rally’s all weekend.

I’ve been doing this all day every day for like a week and a half straight, I’m getting tired, my body is getting worn out from the heat and my emotions are in a tangle, so much sadness, anger, disappointment, passion, hope and unity. It all fills you up in turn, it leaves you so full of emotion but that type of passion gives in one have but takes and drains with the other.

I’m tired but this fights isn’t going to fight itself.

If you care, stop being a keyboard warrior and please engage on the streets. This isn’t some photo op to show halfassed support to feel better about yourself, real change requires sacrifice and your time is the very least you could give.

There was a rally here yesterday but I was working and didn't even know it was happening so I missed it lol.

It was good to hear about it tho, a lot of racism where I live. Still a lot of anger from Inuit people towards white people (rightfully so) as well as a lot of racism towards black people from a lot of Inuit.
The recent history of Inuit people is devastating.

The structural pieces are Lego Technic style, so a lot of beams connected by pins rather than the traditional bricks. They are compatible with regular Lego though. There are also regular bricks with the Technic holes in the sides but there aren't any in this set. In early Technic sets that's all there was. That's what the first Mindstorms set used.
