Quick reminder that we have a meeting tonight.

Lecture Room 1, 2nd floor, fulton house.

Easiest way to find this room is to use the staircase that is in the
right hand front corner of fulton house, if you look at it from the
front.

Afternoon all,

Procrastinating/looking at information for a hackathon I'm going to this 
weekend and I came across this:

http://nodecopter.com/2013/swansea/sept-21

Sounds like the drones would be supplied for the day.

I quite like the sound of a day spent messing around with flying robots, 
anyone else interested?

Hi all

I was just talking to a friend who is in a bit of bother - he needs to find "a company that can supply arduino / embedded processor solutions (hardware and custom software) that have a working knowledge of comms" before tomorrow. Just wondering if anyone knows of any such company? I think he is after custom radio modem controllers.

Thanks

Thought I'd post this as it has an interesting line up.  I was going to go,
but have to more house.

Take a look at https://ohm2013.org/site/ for full details, but a quick
introduction can be seen on their YouTube channel -
http://www.youtube.com/watch?v=1Y5JNMWTaO8  Its basically a hacker-camp
with a huge line up.

Hopefully they will have a few live streams, and post some talks up.

Yeah, it only occurred to me a day or two ago to post about it.  Also it's
only every four years or so.

However would suggest Electromagnetic Fields is something to keep an eye on
for next year.  https://www.emfcamp.org/  They had the first one last
summer, but took a break for OHM2014.  It was a good laugh, and drinking
under a Motorway was a unique experience.

Subject: [Swansea Hackspace] Ideas for workshops
Message-ID: <CAJqsN4Ts9e_C+wedkfWg_w0P_jZjc5M1brEF_H9O2C_CpkqNfw@mail.gmail.com>

Hi people,

Additional ideas for the technical workshops.

I was thinking that - if it has not already been covered, a potential
future workshop could build on the PIC workshops that have been done.

The idea is basically to learn the basic input/output blocks.

examples,

many new people to microcontrollers, connect a switch between +5v to the
pic input pin, then get frustrated that the switch is unreliable due to
floating when the switch is open.  The block would be a switch, with the
the pull-up or down as required.  Explanation of why the pull-up/down
resistor is required.

a simple relay output from the pic, using an easily obtainable mostfet to
drive the relay, and include the protection diode.  Again explain how it
works, and why we need the mosfet, and what the purpose of the protection
diode is.

a simple piezo buzzer, including any protection resistors.

a simple potential divider, explain how to calulate the drop between the
input and output.

how to correctly connect an led, and calculate the current limiting
resistor.

It would be my hope that these building blocks were universal, and could be
applied to any other controller type such as AVR, arduino etc. as well as
non uP controlled projects.  For example using the switch module connected
directly to the relay module would still produce a nicer circuit than
running the coil voltage through the switch directly.

The basic idea is to build a small library of very simple circuits that can
be combined with the existing pic workshops so that people can go away and
build circuits of their own, that will hopefully be reliable, and can be
combined into larger projects by just duplicating these small blocks.

This is probably a horrible description, but I hope that people understand
what I mean.

Additionally, would there be any interest in TTL LOGIC as a workshop?

That sounds like a great idea.  I for one could do with some more basic
electronics knowledge.

What else did we come up with at the social?
I suggested an introduction to the operating principles of transistors, by
building a very basic headphone amplifier.  What was the other idea?

I think other ideas that were mentioned were:

Output control, eg. making things happen in the real world, for example
motor control or servo control.

Communicating with a microcontroller from a PC.  I think this is the
technical workshop for a week monday.

I have 2xPickit 3's that I can bring (Mabey a 3rd and a Pickit 2)  So if
anyone needs to use one, they are more than welcome.

Graham
