Logic analysers and digital oscilloscopes are used when the problem is somewhat elusive. They vary so much in price and functionality. They all handle differently and can be a little daunting.
If you have one of these devices, please bring it to our meeting with any projects or devices that we can attach and checkout.
(i.e. A component tester, dimmer or motor controller for example)

If you have a “portable” oscilloscope, please bring it along to this month’s meeting and we can see if we can recall how to use it. :-}  Also bring along any portable signal generators that you may have which will always be more interesting than the inbuilt 1kHz calibrate reference.

Phil will step us through calibration and the fundamentals of how they work.

Presentation covering a recent client project using ESP32 I did to control a total of 464 addressable WS2812 LEDs,
with user settable colour sequences per 14 LEDs via WiFi served web pages.

  • 2 x ESP32 Dev Kit C boards: one to control WS2812s, one for WiFi. (Reason will become clear in the talk…)
  • 6,000 lines of code over 23 units (excluding libraries).
  • Developed in Visual Studio Code with PlatformIO plugin (both free).
  • Configuration via web pages served via Wi-Fi from ESP32 SPIFFS file system.
  • Fast LED library used to control addressable LEDs (which is trivial).
  • HSV colour format used to ease (yeah, right!) RGB LED colour blending\fading.
  • ESP32s exchange configuration and other info via UART RS422.

Presentation has no set format and will follow attendee’s questions and areas of interest.

Mini demo will be provided, using bread boarded ESP32’s and shortened LED strips.

______________________________________________________________________________________________________________________

The following are notes and tips for those who participated in the Cheapy RK3318 TV-Box to Linux conversion project.

The current Bullseye build appears stable and should be sufficiently endowed for most of our IOT projects. 

Several additional features/apps were requested and have been included.  These are Wordpress, Libre Office, GIMP, Thonny and Minicom.  

The flash image size is limited by Multitool’s use of fat32 which has a maximum file size limit of 4 Gig. 
Current image is rk3318_Bullseye_7-3-2023_docker.gz at 3.98 GB (4,278,726,656 bytes)

Cliff reported that audio redirection is not supported with xRDP, however the audio worked when plugged directly into the boxes’ analogue port.
The xRDP team have published a “fix” for this, but my attempts to install the pulse_audio redirection patches have been unsuccessful as there is an error “locating Pulse_Audio source code”? This may be just an environment variable or pathing issue.
 
I have copied the pulse_audio redirection patches into the /data folder should you wish to try resolving the xRDP shell script issue. 
For those of us who are into Pink Floyd, I have included two mp4 live concerts in the /data folder for test purposes.
The beauty of the Multitool approach is that there is no fear. Should you break it, just reflash and restore your last known good backup that you previously saved on the MultiTool MicroSD. :}>

Other than a Monitor a Keyboard and a Mouse, you may also use the Microsoft Remote access client (RDP) to access the TV-Box when it is attached to your local Ethernet or Wi-Fi network.  Firefox is the only browser installed at this time. 

Mapping to the /data folder is also supported. Just map a drive to the samba share “data”  ie \\rk3318-box\data

Also the following ports for the installed services on the little box are accessible by using an internet browser as follows;

There are 3 login users configured, root, admin and samg each with the same password of samg1234
The passwords for the application accounts and logins are samg12345678

Meeting proceedings for Friday 14th of February 2020

Wayne Sierke presented several versions of flyers he had been working on. He explained that this was a work in progress and invited contributions.

David Zerk passed around our new microphones and wireless mike which comply with Australian Frequency Standards. David brought in a mixing console and demonstrated how it could be used.  After some discussion it was determined that a smaller unit should be acquired for club use.  John O’Sullivan offered to see if some of his loud speaker and amplifier kits cold be resurrected for use at meetings. David moved that several associated items be investigated and this was seconded by Rick Matthews.

Peter Gheude gave a brief demonstration of an ESP-12F Wi-Fi module with ESP8266basic installed.  Several members were interested and promised more on how to interface a TFT touch display at next meeting.  James was interested in how to program the ESP series using a Mac which could be done at the next meeting.

There were insufficient members present for the 2020 AGM as the number of members present for a quorum was short by 2 members.  The Group’s Constitution requires at least 10 members so the AGM was deferred until next meeting.

Cliff asked if anyone would nominate a member for any of the executive and office positions as he would not stand for the Chairman or other role.

Peter Gheude agreed to remain as Secretary/Treasurer.  
Wayne Sierke indicated that he would stand if nominated as Chairman.   
Chris Burrows in his letter of apology for being absent from this and the following meeting offered to stand for the WEA representative.  
Rick Matthews also wished to stand for this position.  
Wayne offered to continue as the Website editor.  
Committee – Colin, Chris, John and David.

The minutes for this meeting are available here.
