Raspberry Pi User Group Meeting (RPUG) - October 15, 2017

Our last meeting at the New Glasgow Library was pretty low key. We are looking at putting together some workshops on basic and some not-so-basic topics.

I really want to make a simple project - a Four Op Amp Function Generator. Forrest Mims provides a schematic in his first Engineer's notebook. You can find all kinds of examples of schematics online. One of the nice things is that it can fit on a single solderless breadboard. There are even IC's that come in packages containing 4 op amps although any op amp should work. I plan on using an LM324. They are on order.

I have some other IC's of op amps, actually some NTE947's for which I used the pinout to redraw the schematic. One of the nice things of drawing schematics using IC's is that you can often just use the old schematic and change the pin numbers specified by the new IC. If you have ever tried to draw a schematic using the pinout of an IC, you will quickly realize that there is an art to the whole thing.

Look for a workshop coming soon.

... by the way, I am also taking a ham radio course with the local amateur radio club, Pictou County Amateur Radio Club.
