2017 Newsletter: 25/73 — PreviousNext — (Attach.)


Hello and Welcome,

New Name for Club:

At the last EGM (March 28th), the members agreed to change the working title of the Club.

It is now the "Sydney PC & Technology User Group".

The official abbreviation is "SPC&TUG".

Meetings for This Week:

Programming - Tuesday 11th Apr - 5:30 pm - 8:00 pm

Come and show your projects, and see some others. We have a computer with a projector, so bring along picture files of your project and we'll project them on the wall. We have a broadband internet connection, so discussion can be wide ranging.

The next meeting will be on Tuesday April 11 at 6pm. We'll see some new microprocessor applications and programming examples.

Past Meetings

At the March meeting Andrew showed how the PIC12 could be used to charge Lithium Ion batteries. This type of battery requires a charging sequence of constant current followed by constant voltage. A PIC processor does not have an analogue output so pulse width modulation has to be used, with an LM317 voltage regulator. Also temperature rise has to be restricted as otherwise Lithium Ion batteries can explode.

However, he said, it turns out, as in so many applications these days, a chip is available that can do all this. This one costs just over $1! It is the Microchip MCP73831T-2ACI/OT, a single cell controller.
