@jwz Could you take a strip of 4mm toothed-belt / timing belt and glue it in there with the teeth facing out of the groove? It should provide enough friction and hold up well but it might also wear down your rope.
@praxeology I tried that and it was impossible to stretch the belt enough to get it over the lip.

@jwz Have you tried an ordinary rubber band inside the groove?
Or something ever so slightly more specialized, like one of these? https://www.amazon.com/dp/B0GGB2MDHT
(sorry for the Amazon link)
@trs Yes, like you, "is there a rubber band in the house somewhere" was literally the first thing I thought of.

@jwz @praxeology if thinking of gluing, maybe just cut the belt, measure in place for the exactly right length and glue it down there with contact cement ? -

@Primavera @praxeology There is not a hope in hell of that standing up over time.

Let Friction Ring.
Dear Lazyweb, I have this pulley wheel, 50mm inside diameter, 4mm groove. I need a rubber traction ring to go inside it. I cannot find anyone who will sell this to me. The ring must be flat or concave, not round like a typical...
https://jwz.org/b/yk33@jwz Misumi sells configurable pulleys intended for round belts, with vee grooves for non-slip, e.g. P/N SL-MBRDA45-2-P8. It’s pricey (US$22). Search on Misumi Components (they’re worldwide).

https://jwz.org/b/yk33@jwz on a conveyer belt system it would be called "pully lagging". But I've never seen anything like it on a machine like yours. Not sure if that keyword helps you?

This child has a plastic bag over her head and mouth, and her mom just yells at her about dry cleaning and sends her off to keep playing with the bag. It was a different time.

AI Assistant Uses ESP32
Having an AI assistant is all the rage these days, but AI assistants usually don’t know about your automation setups and may have difficulty dealing with tasks asynchronously. Enter zclaw. It gives you the option to have a personal assistant on an ESP32 backed by Anthropic, OpenAI, or OpenRouter. The whole thing fits in 888KB, and while it doesn’t host the LLM, it does add key capabilities to monitor and control devices connected to the ESP32.
You communicate with the assistant via telegram. You can say things like “Remember the garage sensor is on GPIO 4.” Then later you might say: “In 20 minutes, check the garage sensor and if it is high, set GPIO 5 low.” It has an RTOS for scheduling tasks and is aware of the timezone and common periods. Memory persists across reboots, and you can pick different personas.
Some of the use cases mentioned in the manual show how having something that can precisely schedule, control, or monitor devices might pay off. Ideas like bringing up a lab setup, scheduling plant watering, and more would be difficult to do with just a stock chatbot.
The AI can also introspect. For example, you could create a few tasks on a schedule and then ask the device to “show me my schedules.” You can also create up to 8 tools with a name, description, and action. This lets you describe something like “power_down_bench” and then tell zclaw to execute it on demand or even on a schedule. Overall, an interesting and well-documented setup.
We’ve seen many projects like this, and each has its own charm. And its own personality.
