Friday the 9th of February 2018

This month is our AGM meeting and all committee positions are open to members. It would also be timely to raise the issue of passing the updated constitution. Each financial member will have been sent an amended copy of the constitution for appraisal prior to the 9th of February meeting. Please forward any queries or possible alteration suggestions before the 6th of February.

After the AGM we have a presentation by Peter Gheude on his new custom built ( Tronxy X5S 3D printer ). Also videos on some of the items that can be built with this printer will be shown if we have time. The Tronxy X5S 3D printer will also be 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.
