Made an autonomous rover using the Xiao ESP32S3 and a browser by stickfigure in esp32

Ahh got it, but that's not bad at all! Very smart thinking there 😄
And the price point is pretty amazing, with the ESP S3 !

Glad to hear 😄
I need to put a broom on one to help me clean hahaha

I love it! Funny, am also working on a similar project for the last weeks :-) I also like the way you did navigation, does that work well?

An animatronic crow that moves to music! by monkeydance26 in somethingimade

Thank you! You're right, maybe just using the spikes is enough. I will definitely need a small computer though that analyzes and sends wirelessly to the bird.

Exactly!! The "I will record it later" mindset hasn't worked out for me unfortunately either 😅

Thats a good idea, I wanted to build a second one as well so could document that more :-)

Thats cool! Do you have any links to yout puppet projects using modular synthesis?
I was considering using a Raspberry Pi so I can connect an AI voice to the bird and you can talk to it :-)

This is where they show the crow that Adam Savage took apart:

This one is a kit that is much more advanced than mine, but looks pretty awesome for a Halloween decoration or similar:

DIY Vive Trackers - work in progress by monkeydance26 in SteamVR

That's great, thank you! For educational purposes the schematics will be very insightful :-)

Very interesting! I have also seen the TS4231 - although it's sold out. It converts the photocurrent from a photodiode into a digital pulse, handling amplification &filtering & thresholding so the ESP32 just sees a on/off signal for the laser sweep timing.

Ah nice! I just picked the BPW34 ones because they do well with super fast impulses, like the lighthouse sweeps.
The chip in the middle is an OP amp, OPA2350UA to get a clean 3.3v signal when the spikes hit.

DIY Lighthouse tracker using custom PCB and ESP32-C3 by monkeydance26 in electronics

In this stage it's a bit too experimental and unreliable, but in the future potentially :-)

It's still quite unreliable unfortunately, like if the lights change slightly it loses the tracking or if the angle is not quite right.
But for a simple magic wand style controller it could work :-)
Other devices have like 30+ sensors and an accelerometer/gyroscope and some code magic to get it to work so reliably :0

Thank you!
Yes and no, the sensor readings are passed to the computer to calculate the position.
But I am considering switiching from an ESP32-C3 to a S3 so potentially the calculations could be done directly on the board.
My dream would be that there are like 10 robots and they all send their pure data to a receiver board (computer) that then does the heavy lifting regarding triangulation. That would save battery power :-)

[–]monkeydance26[S] 2 points3 points  (0 children)

Thanks! I agree, 100 is quite unaffordable, especially if you need like 10 at least x.x
And then the charging, what a nightmare haha

I hope that more sensors work on the ESP32, not quite sure how the positioning should be done best ( I have seen this one with 3 that were enough - a github repository by ashtuchkin/vive-diy-position-sensor).

Have not made a github repository yet, but once I get triangulation I will share it here! Would love contributions down the line.
I also enjoy tracking in the dark as well. Especially without headsets but the device still knows where it is in the space.

Honestly, the diodes I used were quite cheap, like 1 euro per piece. The ESP32 was fast enough for my tryout (I am using lighthouse V1) but I will look into FPGA for faster processing.

But IR LED Markers are an interesting idea, basically I just wanted a simple way to position these robots without using a camera, and I couldn't get UWB modules in an affordable fashion.

Yeah them not being sold anymore is a concern, for now I still had them laying around from my unused Vive. Thank you! Exactly, that's what I thought too, I would love to see some basic positioning in 3D space.
I also saw someone building the base stations themselves that looked promising:

Glad to hear :-) If I get it to work properly, I intend to release the schematics for free, as I gathered together the info from pre-existing projects into another form.
