hippy is back. well alright!

I still haven't got the VL53LOX to play with. Glad you liked Angela Olinto, I had a chance to hear her speak twice, excellent presentations and a lot of good questions. I miss the in person lectures before covid. Appreciate your interest in the topic, I'm thinking the laser triggers the data...

that spiderbot is one hell of a project, highly impressed.

Thanks for your reply. Yes, it's ultra high energy cosmic rays ( UHECR ) I had in mind. Back before covid i was lucky enough to hear a lecture by a physicist that is working on triangulating the source of the UHECR and also to hear her talk about initial deployment. There are numerous articles...

Er Erco, you have exemplary ebay skills, I've been looking for a tiny camera like that for ages. Thanks.

I'll be ordering the VL53LOX TOF module, from little I've read about the sensor it's capable of detecting a single photon. I'm curious if anyone knows how to access just the detector portion of the module without using the laser portion. I'm thinking with a Scintillator screen the module could...

Hippy always came up with an elegant solutions, what would take me 20 lines of code he would distill into a half a dozen. We are so fortunate that others have taken up his mantle, I can't thank Alan enough, if i were twice as smart I wouldn't be half as smart as he.

Wapo I fully agree with your post. I highly approve of fads they make for exponential growth and benefit many. And they also fade. This is the only forum I take part in because the people on here are not the fad types they don't go from photography to bicycles to whatever the next fad is. I am...

I'm just a little younger than you and I think we might be at the forum's children's table. if it weren't for failing health, getting old is delightful, stupid things that tripped me up when i was younger are very trivial now. I think the microcontroller fad is nearing an end, i barely see...

Very sad to hear premelec's farewell. Also, saddened to hear how many of our community are at the same point of life. I very much hope we are all around to see picaxe 08M3.

A quick update, I have the stainless steel wire and am testing it as soil moisture sensor, so far it's working great. I used to use the ebay moisture sensors that use printed circuit traces as a sensor, works well for a year or so and then the traces corrode. Next, I will make water sensors with...

Very interesting article thanks for sharing.

I'm not sure I can make them that cheap so I ordered one. I'm thinking should be easy to interface to a picaxe and have it send a text when water detected.

Thank you all for the great ideas. I will test them for future use. I had considered using a FET but the capacitance (touch) method is something i did not consider. My application is to sense water rising in the pipes going to the main sewer. What happens is tree roots get into the pipe and...

I'm not sure, I found a working program I had for sending to ESP module and it was similar enough to what you were trying to do as far as AT commands.
