Hi Julian,

The WRM1 seems to work the same way as the ones I know. I'd be interested to know how it reacts and what you do with it!

My git hub is alx-s.
I've just added athe RPi_tutorials repo (https://github.com/alx-s/RPi_tutorials) with a first tutorial concerning OSC bewtween python and pd.

Keep in mind I'm new to git and I write the tutorials as I work. If you spot any mistake, have, suggestion or have anything to add, ..., please tell me!

That's all I've written for today but others will come by the end of the week (GPIO, using Maxbotix...). Good luck with it ;)

Have fun,
Alex

I'm thinking this one
XL-MaxSonar - WRM1

look forward to checking tutorials. What's your github address?

Cheers,

Julian

'Power filters' are simple RC filters you can solder directly on the sensor, they help eliminating electric noise. Since the analog output of the sensor depends on the voltage with which it is fed, the cleaner the supply voltage, the better the analog output.
I don't know which sensor you're gonna us, but assuming it works like the MB1000 or MB1200, you will find a lot of useful tips inside the datasheet and in the tutorial page.

I'll start cleaning up my mess and a few short tutorials should be on my github by this evening.

Best,
Alex

Hi Alex,

Many thanks for the info.

What are 'power filters'?

Yes on RPi, so tutorials would be very helpful.

Best wishes,

Julian

Hi Julian,

As for the URF, I can't give you any infos but I've been using Maxbotix's indoor sensors a few times.

One thing you really want to take into acount is the fact that sensors interract with each others, you therefore need to chain them properly.
You might want to take a look at power filters too.
Maxbotix's tutorial page has been quite useful to me so far.

As to get the infos to pd, I've been using these sensors with a raspberry pi.
My option has been to collect the data from the RPi's GPIO using python and then send them to pd using OSC.
I'm starting to write small tutorials explaining what I've been through, if you use the RPi too I'd be happy to point them to you.

Have fun,
Alex

Hi,

I'm after some advice:

For an installation piece I'd like to do I'm investigating range finder sensors (for outdoors).

Has anyone experience of the Maxbotic URF's and any tips they'd like to share for getting the data into Pd?

Cheers,

Julian
