Meetings This Week:

Programming - Tuesday 11th Jul - 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 July 11 at 6pm. We'll see some new microprocessor applications and programming examples.

Past meetings:


At the June meeting Alex described how he made a simple gamebox using a 16x2 LCD, Arduino and WAV module. A Task Scheduler was used to multitask button sensing, character animation and sound generation by the Arduino.

Martin showed how he hooked up an RFM95W radio module to an ESP32 processor in order to connect to TheThingsNetwork.

Steve spoke about using the ESP8266, a WiFi chip released by Espressive. This chip enables many microcontroller designs to access WiFi connectivity and web services at a low cost. Typical use is for a microcontroller to read a sensor periodically and send the data to a website for display.

Friday Forum - Friday 14th Jul - 9:30 am - 12 noon

Not all USB Chargers are born equal.

Have you ever wondered why charging from USB sometimes takes so long? The answer may lie in the type of charger being used. This month John Symonds will explore the varying capabilities of different USB chargers.

He will have a test rig to demonstrate both 240v mains and 12v (car cigarette lighter) charger types.

You can bring along any of your own chargers that you would like checked.

Communications - Friday 14th Jul - 1:00 pm - 3:00 pm

We start with the usual Q&A. Members who wish to discuss interesting computer topics will be very welcome to do so.

Web Design - Saturday 15th Jul - 1:30 pm - 4:00 pm

Our next Web Design Meeting will be on Saturday 15th July.

This month we will be looking at CoffeeCup, a free HTML editor. CoffeeCup is into its 15th edition and has seen some major improvements.

You can download it from here.

We'll start with a look at the workspace and see what tools are provided. The editor has the latest HTML 5 code lists, snippet collections and has an integrated file transfer program (FTP) built-in. Also of interest is the CoffeeCup Library which allows you to re-use or copy large sets of code like a menu over all the files in the site.

After that we can then have a go at building a site. The editor opens with a choice of a blank page, a project or a theme. From the blank page, we have a lot of layouts to choose from. If you go for a theme then your site has all the styles set up. The really interesting innovation is the project option. Using project allows you to control all of your files, images and links.

The HTML editor is not the only free software from CoffeeCup. They have a calendar and a form creator which can be integrated into your files. We'll have a look at those free CoffeeCup programs.

To finish, if you want a free site, CoffeeCup offers S-Drive which we'll dive into. There are some good help files here and I have arranged these into a PDF file which I will add to the Club's website.

David asked if he could bring his laptop and work along with the topic. I would love to see that. It would mean that we could work through topics or programmes and together find out more about the subject. I hope that we can build on that idea over the coming months.
