April’s meeting will be a “Bring Your Own Project” or work in progress and or requiring help with a problem. This evening will include Peter Gheude’s 3D printer progression and the carry over from March’s Part 2 of “The Arduino IDE and coding in C” by Eric Clarke.

Friday the 9th of March 2018

This was be a feature packed night, with the following themes from three of our members. Each presenter attempted to complete their demonstration within 45 minutes or less but due to a time over run Eric’s Part 2 of “The Arduino IDE and coding in C” was cancelled until April.

Peter Gheude demonstrated the latest updates to his Tronxy X5S 3D printer with further mechanical modifications  and upgrades to the electronics on the horizon.

Cliff Shirra displayed his work to date on using the ESP8266 (a low-cost Wi-Fi microchip with full TCP/IP stack and microcontroller capability produced by Chinese manufacturer, Espressif Systems) as a web server.

Wayne Sierke demonstrated his work, using “Rooter” (An open source derivative of OpenWRT. The  primarily use for his system is to route network traffic) on a (TP-Link) router, autonomously.

Friday the 9th of February 2018

This month was our AGM meeting and all committee positions were open to members. The following members were elected as follows:- Chairman – Eric Clarke , Secretary/Treasurer/public officer  – Peter Geude, Web site editor – Graeme Wilson, Committee – Chris Burrows, Colin Huckle (also auditor), Cliff Shirra (also sub editor),  Mark Spooner.

We also revisited the updated constitution and after some discussion the constitution was passed.

After the AGM we had a very impressive presentation by Peter Gheude on his new custom built ( Tronxy X5S 3D printer ). The Tronxy X5S 3D printer was also discussed regarding members interested in buying / building their own unit.

Friday the 12th of January 2018

Wayne Sierke presented a control system that was built to manage solar PV generation at a residential “village”. The equipment uses a proprietary data-over-powerline technology utilising a TI MSP430 (TI mixed-signal microcontroller ) family.

The system management controller comprised a Raspberry Pi in conjunction with a custom interfacing board and control programs written in TCL (Tool Command Language). A testing unit was assembled based around a Freetronics Eleven (Arduino-compatible) controller with input switches and an LCD display.

Live data from the system is sent to web services for monitoring. A custom web-based service was implemented in Apache Rivet with a TCL server component managing communications with the site. Wayne gave an overview of the system and a look at some of the hardware used in the project. He also demonstrated how the various microcontrollers and some of the technologies are used to implement this system.

Unfortunately, Peter Gheude’s 3D printer kit purchase (Tronxy X5S 3D printer) did not arrive in time. However we did have some videos showing a Tronxy X5S being built and in operation.

Wayne has also offered to give future quick presentations on the following:-
– a quick follow-up on the PV Solar system
– a “review” of that Altronics Inventa enclosure
– a look at that “other” type of rotary encoder
– some practical examples of TCL in use
– using “Rooter” (OpenWRT derivative) on a (TP-Link) router
– a quick look at the freescale FRDM-KL25Z development platform

Interested members in any of the above presentation ideas can email SAMG.
