Penwith, Cornwall area meetup

Penwith, Cornwall area meetup

A pub meet up has been arranged for the Penwith area of Cornwall.   This will take place on the 3rd Feb 2018, at Station, House,  Marazion, Cornwall. Between 12 noon and 2pm. 

If you would like more information please contact Jay or Fraser via the DCGLUG mailing list.   But feel free to just turn up.

They will be in the corner near the table football.

Further meetings are planned starting with the 3rd March, which will be a bring-a-box, but this will be at a different location.

 



					

Arduino easy module shield

Arduino easy module shield

Arduino Sensor Shield

Equipment required:

  • Shield
    Arduino R3 uno
    Long nose pliers
    Scissors to open packet

Upon opening the packet,  you get a shield with a foam protective sheet. Fitting the board is easy(ish) partly as you need to align all pins carefully and if need be adjust the to suit the female header on the Arduino Board. Clasp 1 row of pins and move slightly, be careful doing this.

inspection of the board with the Label at the bottom the digital inputs are at the bottom (near to the power in) top row viewing this way you have analogue in then the power in/out sockets.

  • ax refers to analogue pins
    dx refers to digital pins

so on the left hand side

pins for vcc,gnd,sda & scl
below this going down 2x switches (d2,d3)
dht 11 (d4)
below this the reset switch.

Then there are 2 LEDs blue (d13) red (d12)

Potentiometer (a0)

just above this and to the right of the switches
is a tri colour LED (d9-11)

Next to this are 2x 3 blocks pins connected to (d7 & d8) along with vcc and ground pins in. Under this there is  a small buzzer connected to d5 and under that another 3 pin block with vcc,gnd and connected to a3 pin

finally on the far right hand side

serial (4x pins txd,rxd,vcc,gnd)
under that a IR led (d6)
under that light sensor (a1)
and lm35 temperature sensor connected to a2

So in all this is a pretty comprehensive board, the advantage with this is tht you don’t need to worry about wiring, you plug in the code, the components are labeled and tell you where they are connected so no messing around trying to find data-sheets or notes.

Upon connecting a usb lead for power to the Arduino the Blue LED same as the red LED on the Arduino board, which is by now covered up by the shield.

Quick test of the board using the Arduino blink example (modified)

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.
 
This example code is in the public domain.
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
int led2 = 12;
// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);
pinMode(led2, OUTPUT);   
}
 
// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  digitalWrite(led2, LOW); 
  delay(500);               // wait for 1/2 a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  digitalWrite(led2, HIGH); 
  delay(500);               // wait for 1/2 a second
}

Plymouth Lug meet write up Sept 2016

The September DCLUG Plymouth meeting was held at Hush Coffee. For a
number of people, it was their first LUG meeting, and everyone seemed
to have a nice time. We had a demo of
the Pocket CHIP,
MoonReader, libreboot, i3wm,
Debian/KDE,
and kubuntu. We talked about
Linux-related podasts (Bad
Voltage
, GNU World Order,
Linux
Luddites
, Linux
Voice
). We had an update on the Open Computing project at Plymouth
University, and we talked about some of the local events that had
happened recently,
including Code Club at
the civic library, Torbay
Tech Jam
and
the MiniMaker Faire at
Bristol
. We also talked about open computing and open science –
includuing R and data publication. There was also interest in retro gaming on Linux,
including the text adventures Lost
Pig
and
Jigsaw, and the
‘Get
Lamp’
documentary. Other retro computing topics
included: pico-8
and ZZT,
plus various emulation platforms
(Scumm, Doom, Playstation
1
, Spectrum,
and BBC Micro).

Rebelmakers

Rebel Makers is a network of peer-to-peer making clubs for everyone who is interested in technology – regardless of age or ability. At our Clubs, Rebels get together to share existing knowledge and learn new skills in a fun, safe and collaborative environment, exploring anything and everything from electronics and programmable hardware, through to writing code, design, and media production.
The Torbay Tech jam is trying to tie-in with Rebelmakers  so that we can be work closer togethe,r offer more support / activities for anyone who attends the jams.  For this to work we really DO need more volunteers to sign up and help,  as myself and tom are struggling to do the jams as it is.

I am not sure what is possible so as a plan B I am looking to find other potential partners to work with them to run clubs for ALL ages and abilities in the heart of torbay communities so we can really bring together people with similar interest and develop a vibrant techy  / hobby community

Kevin From rebel labs who run rebel makers will be down in November so if anyone is interested please come along to the jam for a chat,  and lets see if we can get anything going in Torbay.  It would be really nice to be able to offer far more support to the people attending the jam than we are at the moment.

Please visit the tech jam site and get in touch for more information.

libreCMC

The libre Embedded GNU/Linux Distro.

“libreCMC is a set of fully free embedded Operating Systems for general purpose computers. It aims to give its users freedom and control over the software that runs on their hardware. Most of the hardware that libreCMC supports includes a wide range of routers and some small single board computers.”

This looks interesting and perhaps can make a project for a tech jam to look at.  If anyone is interested perhaps chat at the jam or on IRC.
