Thanks. pulseaudio wasn't installed. I did install Samba so I could easily transfer or access the recorded WAV files from my Windows machine. Seems like at least some of the crackles are in the recorded WAV files.

I have a Pi 3 Model B 1.2 mounted in one of those 7" LCD touchscreen cases. I have modified the GUI code for SooperLooper http://essej.net/sooperlooper/ to hide some of the features which I never use and make it possible to display 3 looping tracks on the LCD. This is all working quite well. I am us...

Well, I wish I understood why this happened, but I rebooted and it went away. It had nothing to do with using VNC as the exact same thing happened when I was connected with a keyboard. So now I'm able to edit the SooperLooper UI!

I'm pleased that Raspbian includes SooperLooper in the default repositories. I set up my Pi 3 with one of those 7" LCD touchscreens, connected a Behringer UMC-404 HD audio interface and a Macmillen Softstep MIDI foot controller. Routed a couple of MIDI and audio connections using QJackCtl, all worke...

Weaved is in the process of transitioning our corporate identity to remot3.it. You can find the answer to this issue and others at our new Help Center: https://remot3it.zendesk.com/hc/en-us/articles/115000153112--WARNING-NONE-in-Service-Column Yes, the issue is that we do not install a web server fo...

Update... I rebooted to CLI. Makes no difference. I think my comment about 48000 WAVs working better than 44100 Hz ones was off. I just had downloaded some 48 kHz WAVs which were longer, so I could actually hear most of them. But since I wasn't familiar with what was in them I did not perceive that ...

Little history here first. I have a couple Raspberry Pi "A" models which I think were from the second shipment ever. Yes I was an early adopter! :mrgreen: I wrote a Python/Pygame program which is a timer with audio outputs (recorded wav files). This has worked generally pretty well for years and yea...

Digital Larry

Thanks Gordon I will give that a try.

I will pursue answers to these questions over at the LXDE forum, however anyone who has the answer ready is welcome to offer it. :D For example, items in LXDE autostart definitely are restarted if the system discovers that they are no longer running. Something else I just noticed is that the sound t...

Here's another question. My Python program locked up (I'm not going to say that it is completely debugged). I got a terminal on the device via VNC and did ps ax | grep python I found 2 entries, one with sudo and the other not. Both of them refer to the program I wrote. I could not kill these with su...

Digital Larry

Thanks guys! We are almost there. I did as you suggested, and everything is running, however: 1) Browser is on top of Python program even though it is called first in autostart. 2) ssh password warning dialog is on top of Python program 3) Python window wants to be pushed to the right hand side. Pyt...

I've attached a screenshot of my Pi3 with Jessie/Pixel desktop. This is connected to a monitor mounted on the living room wall. The Chromium browser runs the sigalert web site so I can see local traffic conditions and the other thing is Python/Pygame program I wrote that reminds my kids to take brea...

The main reason for getting a blank screen on a Weaved web connection is simply that the web server itself is not running or is perhaps on a different port internally than the Weaved service was configured for. Please double check that when you are on your LAN, you can connect directly to it by typi...

Interested to see what you come up with. Am following the Xmos kits as one of their engineers has done a fair amount of work in creating audio effects (e.g. for electric guitar) on it. He's been talking about the possibilities a bit here.

I've written a few programs for the Pi in Python. Loads of fun. Up until recently I have been checking the source code into a SVN repository from my Windows 7 PC, and then using some scripts to checkout certain source folders from my Assembla repository down to the Pi. So there is a working copy on ...

Digital Larry

I updated the code, it now does spirographs and harmonographs. I also built in a "sequence" mode that takes a specific curve and iterates through a set of incremental drawing parameters, specifically phase and damping, so that you can see these curves appear to rotate in 3D. Right now it just genera...

Sure would enjoy a script to help configure a USB WI-Fi dongle for WPA. I've done it a few times but all by hand.

Digital Larry

Well I'm glad I asked here, because although I really DID understand aspects of OOP from C++ many years ago, and I really DID make some Python classes, I was not exploiting them at all properly until a few days after I made this post. I had this sense that I was really passing way too many sets of p...

Many years ago I needed a pseudo random number generator for 16 bit values in an 8031 based system I designed. I just experimented with different values of x and y in the very simple relationship: next = last * x + y ( of course limited to 16 bits) I don't recall the magical values of x and y but I ...

Sometimes I get syntax errors which are the result of leaving something off a previous line, such as a comma, or close paren, quote, or the like. It would be most helpful if you could copy and paste all of your code and enclose it using the "Code" button so it keeps the formatting (indenting is crit...

I installed Apache last week. SSH console slowed to a crawl. Eventually I settled on lighttpd. I installed PHP5 and MySQL. Then I installed WordPress. And I got pretty excited when it worked. But my application for this is not to be a general pupose WP server. It's just to have a pretty front end on...

I'd tend to agree it's not suitable for that age. The Linux desktop (I tried LXDE and Xfce4) is noticeably slower than any other typical personal computing device, plus you are at the mercy of whatever kid oriented apps are published for Linux. Which is some, for sure. That said, my Pi keeps track o...

Timelapse of the purely mechanical variety was a passion of my dad's when I was growing up (make that 40 years ago). I'm sure I will check this out when I get my current projects under control.

Thanks!!!!

Digital Larry

What was the problem?

Digital Larry

Hey thanks for the feedback!!!! :D As with many design quandaries, I thought if I just came over here into the corner and mumbled about it with myself I'd get to some breakthrough. In the back of my mind I am trying to make the curve equations as general as possible - well that is pretty tough becau...
