github.com/ruenahcmohr/littlebot/… here is the code for this bot so far. sorry, it depends on the ch32fun library in a way I have not succesfully untangled yet.

ok, the mouth array ended up being made of those RGB LEDs I have like 30000 of (not all stripped yet) It turns out the red led on lots of these doesn't work??? and finding leds balanced enough to parallel like that was a pain (I dont have enough voltage to series them)

so... The wireless serial module I glued into the robot is faulty.... huh...

The RC loader uses this remote, so I just need to copy-paste its RX code into this little bot and everything should be great....

The 2.4G serial bridge modules I'm using are a pain to get into programming mode, I managed to get some configured

My initial thought was to cram a bunch of surface mount LEDs into the eyes and mouth, but they are sort of too small and I have other leds that will work fine.

ok, There was a lot of interaction going on on other sites and I didn't get everyone else updated.... wiring up the motor drivers for this weeks robot (52 robots in 52 weeks)

Morning random image 2015: Who was eating this hot water tank? RUE!!!!!!!!!!!

haha, package from aliexpress, uh, its the toy :] I know, I should have just 3d printed it, but...

How I know my pullups dont work: hook up a logic analyzer and watch everything operate properly....

This website still doesn't have polls? How am I supposed to gauge people's coffee mug hygiene?

after a series of extremely tense calls with UPS customer service in which a rep threatened to "put the package back on the boat" I managed to get them to let me self-clear and avoid the 78 dollar charge, HUGE thank you to @cdrom.ca for linking me to this page goingawesomeplaces.com/how-to-avoid...

its me

yes, and at that, I need to write some test code. I still dont know some things on finishing this robot, but I will hope it just all works out.

morning random image: 2017: You can just build a CNC machine.

Tension clips and installed the Z-drive units. This gonna look awesome 👀 #Voron

ok, stepping 4V up to 8V so I can step it down to 3V, cause that makes sense, right?

I've been streaming again, good to see new people joining! Welcome here if you're new 💛

drat, if I could fit a 9V in this robot I'd be set.

Having a hard time not being scared of a US invasion. Got some more assembly on this weeks robot, but I caught a design problem. Go figure, its the power supply. Those converters are only good down to 4V, I'm using one li-ion cell. pre-doubler?

Morning random image: 2019: working on a high rez scale for measuring the weight of 1 screw to sort it.

Can I jam all that into this little robot? well I think so...

The i2c IO chips are expensive, and I'd LIKE each IO device to be its own module. I do not think thats practical for this robot. I SHOULD just use a 14 pin CH32 and operate the IO direct. But I want to explore the serial bus thing.

The system is what I'll get stuck on. I want to explore serial busses to IO controllers. I CAN use synchronous serial to a 74595, but would like the expandability of i2c.

Hmmm, this is the smallest battery I have. It fits, but I wont expect much runtime :]

Here is stripped down more, I took the wires off, removed the eyes lamp.... I think I can fit a motor driver and stuff beside the motors there

It seems to have some OK voids in it....

--------52 robots in 52 weeks-------- so, I'd like the 3rd robot to be a bit simpler. I'm going to pull this off the shelf and add batteries, wireless comms, and a microcontroller.

heh, in the morning realizing I forgot to do the posts yesterday...

hmm, I wonder what I have for code that does step-direction to dc servo motor with encoder...

ok, so due to time constraints, I need to change the goal of this weeks #robot. instead of seeking darkness, it will GeNeRaTe a LoT oF LiGhT and ... dance... :/ I'm sure these #robots will be re-addressed later in the year, here is the 2nd robot/week of a-robot-a-week for 2026. (sorry)

"STOP!" "What?" "STOP building the robot, it needs more LEDs" "But, we are REALLY short on time to.." "NOPE, IT NEEDS MORE LEDS" "but..."

(its brighter in the photo than real-life)

I love these little leds, I spent some birthday-gift money on these :]

😅 I have seen too many people having fun with this EL wire and want to try it myself...

aha! and here are the ones with the 3mm holes! These are for making linkages that works with M3 screws. The numbers look a bit tight, so I got the other ones for M2.5 screws just in case.

Aliexpress mailbag con't. hah, I have a computer that needs a new power supply, but I'm gonna make it myself, I decided to cheat and get a 12V isolator for the -12V supply (3w)

power pack!!! Lots of people seem to be having success with these, I thought I would get and try one.

PARTS FOR BALL LINKAGES!!!! (I'm going to print the rest of it) These are 6mm beads with 2.5mm holes, I also got some with 3mm holes.

ALIEXPRESS TIME! (I'm funding the manufacturers of supplies for ww3!) :/ WIRELESS CONTROLLER!!! (with the thing!) The thing that makes it UBER EASY to connect the controller up to an "arduino" WHAT ELSE HAVE WE GOT !!!????

Motor driver all wired up, I need to write some code and test.

new blog post: my life with computers or how i got my first computer and how everything went downhill from there - part 1 https://kiwa.space/mew/comp.html

controller board for this weeks robot, ch32. blinky works, can I stop here?

maybe next weeks robot?

I was given this (roller issues), what ya bet if I crack it open I find GRBL fingerprints?

I'll try ch32 for this weeks robot...

I might get stuck playing with my power leds.... I love this rear mounting thing...

ok, so I'm taking the robot batttery pack back to 12V so I can use a boost module for the motors and a buck module for the logic. I hate this but if I dont do it I will lose.

I did a lot of work to clean this core and its a stupid storage core, I wanted a pushpull.

Completed the frame and this thing is super sturdy. Looking forward to continuing the build! #Voron #3DPrinter
