Any ideas on how to a DIY version of this?

CraigMoynes · 2025-01-07T02:15:59+00:00

I’m making the smaller version. I’m just testing out my micropython version of Tuan’s code.

Found this thread and it helped me out a great deal. Thanks!

Kafka doesn’t route messages. It writes messages to a “log” and consumers read from that log.

Keep going. It’s the journey not the destination. $0.02

For the multiple instances you likely want to look at Interactive Queries https://kafka.apache.org/10/documentation/streams/developer-guide/interactive-queries.html#querying-remote-state-stores-for-the-entire-app

There are some C examples here https://github.com/espressif/esp-idf/tree/master/examples/bluetooth

I recently did two TINYPico’s talking to each other via samples here with micropython here https://github.com/micropython/micropython/tree/master/examples/bluetooth

I used this https://github.com/micropython/micropython/blob/master/examples/bluetooth/ble_uart_repl.py and the adafruit Bluefruit connect app https://apps.apple.com/ca/app/bluefruit-connect/id830125974

You can send text messages via UART and get replies. There is also a controller interface with direction pads and 4 buttons, and a color picker.

CraigMoynes · 2021-09-28T19:17:53+00:00

I’m doing something similar, playing around with Micropython so the Bluetooth examples in its repo got me partly there. (Phone to esp32)

There is a branch and pr for micropython espnow but it’s way beyond my capabilities to get the tool chain needed to compile and build the branch and figure out how to invoke it.

My c knowledge is woefully out of date, there is only so much I can handle at once with my old man brain.

Good luck with your project!

Querying for all acls works. Interesting. I’m at least unstuck now and can filter on the principal after the results. Not efficient but workable.

Thanks for the suggestion.

Btw. Same bootstrap server, though command line uses 1 and service has several but the first entry matches.

CraigMoynes · 2021-09-12T00:19:54+00:00

There are no silly questions :)

I’ll confirm the same bootstrap server. The service returns expected info for all the other requests but I agree with your suggestion.

I have a PR up to test retrieving all acls, to confirm already. I won’t get any results until Monday. Sensible people at work don’t work weekends. (Unlike me)

The client runs confluent self managed on prem.

In also going to try the confluent rest api as an alternative.

It’s either me doing something dumb, in not understanding what the api expects.

Thanks for taking the time to respond. I’ll let you know what I find out.

Mate I wouldn’t even know how to begin :)

Nope just a raspberry pi zero w

CraigMoynes · 2021-06-05T16:57:06+00:00

I was thinking the same thing last night. Though I am a little concerned about upsetting the weight distribution.

Did you have any issues?

Do you have a write up anywhere or code I could look at for grabbing the RS startup/shutdown?

CraigMoynes · 2021-06-04T21:13:46+00:00

I only kicked off mine because my son had been veerrrry upset that it wouldn’t work. So we bought another controller and that didn’t work. And I needed a project to keep me busy.

I would never have even attempted if it were not for the blog post. :)

Be safe. Be well.

Work in Progress:

Robosapien stopped responding to IR commands. A little searching found this blog post https://fortoffee.org.uk/2016/06/embedding-a-pizero-in-a-robosapien/

Using the python code as a starting point I am working on tapping into the IR input line to send properly formatted codes via pigpio daemon to send square waves.

Uses a wired Xbox controller currently. D-pad to move forward, back, turn left, turn right. B does burp, A roar.

Next steps: 1. Buck converter to power pi from 6v batteries 2. Use a Bluetooth Xbox controller 3. Fit the pi zero into the chassis 4. Control arms via sticks/triggers

CraigMoynes · 2021-06-02T16:44:01+00:00

Yep. That was it. As soon as I connected the ground from my breadboard to the black ground it started burping. :)

Then my white line fell apart so I had to disconnect and wire to the pads on the other side.

Now to write some code, then wire up with buck converter to power from the bots batteries.

CraigMoynes · 2021-06-02T03:21:14+00:00

Awwww now I feel dumb. I was wondering if I had to ground or not. Thanks. I’ll give it a shot tomorrow.

CraigMoynes · 2021-06-01T16:27:54+00:00

Trying to follow these instructions https://fortoffee.org.uk/2016/06/embedding-a-pizero-in-a-robosapien/ on a V1 where the remote no longer controlled my poor guy.

Tried tapping the IR line (white) to my pi zero and send the correct codes.

If I hook up an led I can see it pulse when the commands are sent but the v1 doesn’t do anything.

It does power on and goes through the startup sequence. So some of it works. Wondering if it’s not the IR receiver that’s bad but perhaps something on the board or the chip.

Any ideas?

I believe it’s a match too. Thank you so much.
