Cobbler Kit

Raspberry Pi Cobbler kit

In order to allow the Raspberry pi to be used for circuit protyping without risks of shorts or bent pins we had to solder the cobbler kit together.

The tools I used for this task were a 12W/ 230V soldering Iron with a stand & damp sponge.
The Pi header kit came in numerous parts (http://www.amazon.co.uk/Adafruit-Cobbler-Breakout-Kit-Raspberry/dp/B0093K6QQ0) and I had to solder them together so we were able to connect to a breadboard.
To do this I had set up a workstation in a well lit and well ventilated area at one of the work benches as it is not recommened to solder whilst sitting incase you drop hot solder/ the iron on your lap.
To allow a clean connection it is important that the solder connecting the pins to the board do not touch each other, only touching the small copper area located around each hole. It is crucial to allow the solder to melt before you attempt to place it on the board to avoid mess.
After I had done I gave the kit a visual inspection to ensure that the solder was shiny and not touching anything it shouldnt be. I also got a second opinion from my tutor.
To record my information I took a before and after shot of the cobbler kit.
The kit was soldered for IteC as project for trainers.

Product spefications:
26 Pin Ribbon Cable, Custom PCB, Ribbon Cable Socket and Header Pins.

The majority of my work was spent with the other members of the group as we continued to prep for an upcoming exam until I broke off to the workstation to begin soldering, I had more experience in this area.

First workshop

A few inital hiccups (Moodle ones not Pi ones again!) when the open guest access meant registered learners too were deposited in the course without enrolling.   Sorted temporarily during the day by turning off guest access.  On again now, but learners will have to manually enroll from a link at the side rather than being prompted.

As discussed here we went through some aims and objective.  Interesting to see where the learners priorities did and didn’t match ours!  (The bid objectives tallied up but their assessment of what they wanted to learn and what we thought they needed to learn were rather further removed!

ITeC’s Aims

Our Cross-curricula requirements to get the Welsh economy and culture involved in everything we do is still proving a challenge to get learners to fully take on board.  Surprisingly they don’t prioritise awareness of the job market either – we definitely need to work on that!

Skills The Project will Need

The research and self study skills which have been a concern to the staff in the past still are not seen as a priority either.  I wonder if it’s because they think they are already good?  And how they’re defining ‘good’ – any of you out there care to comment? 😉

Most learners engaged well with the activities although I think we’ll add more direction to what we mean when we say have a god and tell us what you think!”  They have had very little practice in using different applications and systems and comparing the advantages and disadvantages – probably comes of always having been told “Use this””

We watched the following video.  Probably it’s more aimed at tutors, but we keep saying this is, in effect an adult programme and this is the level of learning that their CPD is going to need in an IT world.  Part of the Moodle course involved summarising the aims as stated in the video and everyone got the gist.

The cloze exercise for the background reading working well, prompting lots of discussion and some unexpected literacy work as we discussed how we could get clues from whether the sentence meant the gaps needed a singular or plural answer!  I’ll definitely use that again!

For the practical part we had two Pis (one a learner’s own) between 8 so had a two small groups working on the Pis and a third using live USB boots to try out Linux itself.

There’s some more writing to be done on the wiki but overall it went well.

Raspberry PI achivements and news

Raspberry Pi won another award for innovation of the year at stuff gadgets 2012, which I think is great as Raspberry Pi lets the users do  so much which lets them use their own innovation.

Picade is using Raspberry Pi to create a mini desktop arcade game, with a real joy stick and buttons with a solid carbonate case. I think this is great as people can play classic games such a Pac-Man on a classic arcade style platform.

Raspberry Pi is being used in schools using censors monitors and lights including programming, and also students are enjoying using Raspberry Pi’s. I think this is a good idea to use them in schools as students can learn different things such as programming.

Raspberry Pi teaches programing

The Raspberry Pi  is as a device to teach programing, it has being  brought in large numbers by hobbyists and developers due to its low cost and Linux support. The Raspberry Pi is capable of teaching programing to those who already don’t know how to. I believe the Raspberry Pi will be influential to new programers as it a lot more affordable than the other available programing technology.

Raspberry Pi turned into a portable Computer

A Raspberry Pi has been made into a very small, portable computer which includes a keyboard with a mouse pad, and also a very small monitor. The portable computer also uses very little power and is connected up to a Battery. SK Pang Electronics connected the keyboard, USB power pack and small LCD monitor to the Raspberry Pi. They had to overcome a problem where the power pack only gave out 5 volts of power, the monitor alone needs 12 volts. A quote which shows that they did “The 5v regulator was bypassed, but that can cause issues as the voltage protection is removed and the display could get damaged if not handled correctly.”

1940’s TV, Resurected With Raspberry Pi

Andy Brown has been working on a project to re-create a 1940s TV using a set he found in a barn a few years ago, and a Raspberry Pi. The TV plays period programs from a USB hard drive (it can also stream content from the internet), and will be part of a display at Making the Best, the Brown family’s shop in Leighton Buzzard, Bedfordshire. Video first from different stages in the project’s development, then some explanatory notes from Andy.

I think this was a great idea to restore a television using the Raspberry Pi, it really shows one of the many possibilities of the Raspberry Pi.

Teaching Pi

There are a few schools that use Raspberry Pis to teach programming/coding, and this became a hot topic at the Broadcom Masters Program. They decided to then set up a scheme to replace their science fair, where they give Raspberry Pis to a bunch of students. Then they where told to create a simple game using the Pi even though most of them haven’t had any programing experience at all. They had to code/alter a very simple game like snake which can be found on old phones that they received from a Broadcom employee. They had to do this within an hour. The co-founder Dr. Henry Samueli stated that;

“A key part of our mission at Broadcom is to promote math and science education at all levels. This is the culmination of a year’s worth of work.”

I think that this was a great idea as it shows how easy it is to use and that it can easily be used in schools to teach programing to kids who have a interest in programming or want to give it a go. I received this information from a article by “ZDNet“.
