Serial terminal into a vive lighthouse.

This video was recorded on May 27, 2017. I just didn't get to uploading it until now. Sorry guys.

[@drkastenbrot]

That ASCII Lighthouse doesnt necessarily give the impression of a lighthouse...

[@NickMoore]

Very cool, thanks for taking the time to look into this.

[@MinecraftM0b]

Wow, keep up these video's. They are pretty interesting! btw, i think you forgot the invite link to the discord server of yours :)

[@CNLohr]

good call! fixed.

[@ramradhakrishnan9382]

CN, Always interesting to watch your KZbin offerings including this one! BTW, have you cared to try out the ESP32s? At one time I recall that you were big on WiFi performance, WebSockets and WS2812's and it was a great help when I started playing around with those, and I wonder if the supposedly higher power of the '32 may tempt you to revisit those older projects?

[@CNLohr]

I've done a good bit with ESP32s, but nothing about them is really any more interesting to me than what I can do with an ESP8266... so no real attraction. All of the stuff I wrote for the ESP8266 drastically outstrips the real-life performance of similar libraries on the '32 sooooooo

[@PrivateYTPlaylist]

How'd you mean exactly? All the stuff you do/done with the ESP8266 cannot be done in a better or in a more performant way with the ESP32? So you have no attraction to develop on the ESP32 specifically?

[@CNLohr]

Yeah, basically. There have been projects I've wanted to do something with that I thought "OH I CAN DO THIS WITH THE ESP32" but then it turns out it was easy to do on the ESP8266, a smaller, lower power chip. Takes less time to compile for, too.

[@Lethaltail]

that is adorable.

[@ge2719]

Some long tweezers would have made that a lot simpler :p

[@Tutankhamun1333]

Thats why they cost AUD $200 to replace or buy for a self put together htc vive system from parts or sold on gen 1 htc vive head set after to pro upgrade.

[@stupidgenius42]

What did you use to connect this to a PC?

[@CNLohr]

A cheap "ttl serial adapter"

[@stupidgenius42]

@@CNLohr I was using an FTDI programmer so that might be why it didn’t work for me.

[@zsigmondforianszabo4698]

Umm i am really a noob here, trying to explore the lh2.0 by myself (gonna check out the live stream) and I don't get it why you're disassembling the lighthouse for connection. I can communicate on USB serial via putty and able to send commands there. I don't get what is the difference

[@Steam_VR]

For some reason Lighthouse 2.0 has a serial connection embedded on the USB, but this is not the case with lh 1.0 afaik there is a "recovery mode" for flashing the EEPROM via USB, but no way to get serial.

[@buchnermichel]

Question, did you upload a custom firmware to achieve this? I would like to set "rotor.0.enable" "rotor.1.enable" to false, preferably without uploading new firmware...

[@CNLohr]

All of this was using stock factory firmware.

[@DiyintheGhetto]

Hello Charles let me ask you a question. On the lighthouse the rotor's/ Fly wheels haves the lasers on them that sweeps the room left to right and up and down correct? Then what are the IR Led's for?

[@CNLohr]

To give you synchronization to know where the rotors are at any given time

[@axlecrusher]

Cool

[@TheJuke19]

So the only reasons you are trying to tweek the lighthouse's flash frequency is for the esp8266s to identify the lighthouse it received the flash from?

[@CNLohr]

Correct, this was when I was interested in tracking many lighthouses simultaneously.

[@tramplerofarmies]

Has anyone done this, or similar, over the wireless interface?

[@DERlpschauer]

so i just stumbled across this video, can anybody explain to me why you would want to do this? what advantages does that have?

[@CNLohr]

It is just an insight into Valve's base stations and may help others if they want to make systems that use the lighthouse tracking system.

[@drink__more__water]

Sorry, I'm really unfamiliar with these... is that a gyroscope inside it? really not sure what is going on here...

[@TurkishLoserInc]

The reason why it is called a light house is because I do believe it has a spinning lidar which is generating a point cloud of the room.

[@Eslar]

AFriendlyMathematician false. The lighthouse tracking realy depends on timing. It sends an sync impulse when one rotor is at a special position. On these rotors is a laser which sends a Line throu the room. If you messure the time between sync flash and the laser hitting a Sensor, you will get the angle relative to the basestation. Doing this with multiple axis and multiple points on the tracked object, you can reconstruct the position and rotation relative to the basestation.

[@TurkishLoserInc]

Eslar Fuchs How exactly is using a laser to track NOT lidar, when that is it's definition? I understand that it doesn't generate a point cloud,which is likely why you said it's false, but we are refracting a laser, then using an IR grid to identify where the response is coming from.

[@nrdesign1991]

a laser line is scanned across the room; the detectors are spread across the surface of the controllers and the headset

[@edward17829991]

AFriendlyMathematician they just work on different discipline

Hi CNLohr, I sent you a message in KZbin where I suggest some Important Electronics Projects, so you can check the received messages in your channel on KZbin, Thank You.
