I don’t seem to have had a lot of time lately as things have picked up at work. I also can’t find any information regarding heat transfer, I guess I’ve looked at it a few times but just been to thick to see it, what is a watt in terms of energy anyway? I think it’s as simple as one Joule in which case all the sums are a piece of cake (Cherry Bakewell… mmmm). Have 3 days off work next week, 2 days for the Gas Assessment and a day to arrange some bits that will no doubt need arranging by then, all reference forms have been filled out for the new house so just a waiting game right now.

Reading back it seems I need to dedicate my entries to some kind of theme… I may start off with some things which are running through my mind at the moment. First off I need to do a bit of study for my Gas assessment next week, I am re-taking my gas safety exam so I can again become CORGI registered (although it’s not Corgi anymore but thats a different subject) the problem is where do I find the necessary material to study? That’s my problem, secondly and more bloggably, I need to donate some of my free time to the design and development of a bit of test kit for the production team at work, this is basically a flat bed made of copper that can be meticulously regulated between -10 degrees and +50 degrees centigrade. My design concepts are quite simple:
This is a Peltier Heat Pump:
Now this device is used prolifically throughout electronic design for cooling power hungry integrated circuits in the form of Processors and power electronics, note I deliberately left out the prefix “micro.” One fantastic property of this device is that it is polarity dependant, meaning one side will heat and the other will cool, but if you reverse the polarity of the supply current, the side that heated now becomes the cold side etc… So i need to cool and heat a plate, the electronics are simple, but I need to study the mathematics to determine the size of heatsink. There are hundreds of pre-manufactured heatsinks available with detailed technical specification, but my method is slightly “out of the box” in so much as I want to cool the plate and “heat” it, which means using ambient heat as the source. I know there is a simple formula to determine the parameters I am working with, but it seems that the ideal solution is difficult to find, on continuing research I believe I will eventually have to develop a bespoke set of maths to deal with this issue.

This blog is getting quite boring, my posts used to have a topic along with pictures but I cannot seemed to be arsed anymore. I did at the beginning, consider devoting my domain to a single subject, the most obvious were Phenylketonuria, Radio, Electronics or Guitar, but it kind of evolved through my lack of enthusiasm into an inane and mostly pointless collection of ramblings that very few people, seldom read. So I have been re-considering a topic, possibly a day by day diary with photos of a project I could undertake, I am trying to resist an informative site about P.K.U. with tips and recipes etc., there’s quite a few out there already and I’m not prepared to deal with PKU in pregnancy or infancy only adulthood, that may seem a little biased but I will getting no renumeration. So I must excogitate for a while and think of my whys and wherefores, I will have a more settled foundation from April 24th when there will be a more fruitful outlook… at which point time will tell.

Sausages come to mind, and where is Chain? I miss the old fella with his bizarre outlook and witty repetoire. Things around are evolving, and I guess there is a reason for this. Where we are going and what we are doing is a mystery to all of us, it seems the recent decisions by our government and the influence of others around the world is vital to our sustainability and the present comfort of life we have become accustomend to. So be prepared!

Oddly I feel my words are suspended in thin air, I find it odd now how many credit card and bank adverts are on T.V. Do You? If not, is the scale of the economic turmoil making any difference to your life? You may think not, or maybe a little, now think again. If you don’t you will… soon.

Having a stressful day, back to fucking RDT’s at work, no lunch, so tired falling asleep infront of PC and time going so sloooowly I keep thinking somebody’s been fiddling with the clock. Still, will be looking at a house in Polegate soon which I’m looking forward to, Lisa is picking me up from work so I don’t even have to kill myself cycling up to the Ridge tonight. Everytime I do I tend to flop out when I get back and have myself a mild asthma attack. Gas assessment for the 23rd of March so I can get my Corgi back and earn some reasonable money for change, I will stay here working and just advertise for breakdowns and Landlord’s Certificates I can knock out either evenings or Saturdays. Anyway, must bog off.
