Struggling with computers at work at the moment, first of all lost the network so had no Internet connectivity so I nabbed a mobile wireless card. Realising I have now bypassed the company network I set about downloading some of the useful apps that were blocked by the company Internet Security software. Ive spent the best part of 2 days making significant changes to the design of my Multiplexer PCB only to have the PC crash and corrupt the file, so it is gone!!! I’m running the design software on a seperate PC with Windoze 2000 and its about as stable as the Middle East, so lots of fun with computers today…Grrr!!!

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.

Finally I seem to have stopped coughing! I think… I also seem to’ve stopped a lot of other things and am beginning to feel a little displaced. It’s incredible the effect of dropping one tiny M4x10 screw into your car engine can have, now that I know the car is basically shagged, I need to buy another or continue having my whereabouts dictated by my inability to drive. Everything seems to be in slow motion at present, although time in motion cannot be regarded as the present; as the present is a moment in time without a period that can be measured, if it had a beginning and an end then they would be past and future respectively at any point inbetween, so in effect, the present encompasses past, present and future in one unit. Really everything is in the past, as when we witness an event in the present, it actually takes a fraction of a second for neural impulses from our senses to be transmitted to the brain and processed into the reality we consciously perceive, therefore we are actually riding the wake of the present a fraction behind in the past, so the present could be envisaged as the future. As we never catch up with the present, how do we know it actually exists? The future is different as we can fix a time in it and know it will arrive and pass.
Ooops! There I go again off on a tangent, time for bed.

Things are changing at a pace I can’t comprehend, I always thrived with stability but at the moment I have no idea where I am. My car is dead, I stay at Lisa’s during the week as its a half hour walk from work rather than a 2 hour £5 return train journey an hour of which would be walking. I’m looking forward with great anticipation to moving to a new house in the Summer, but it seems such a long way away. I will then hopefully be able to restore my routine at the gym and forge the stable environment I need to thrive. But at a glance, I can see I have something to work towards, a purpose I have craved for all those years I stagnated in my 6×8 room, that purpose will provide a foundation and stability so I can at last be happy.
I’m in a kind of odd mood. Work is quite intensive at the moment, I have to design the PCB layout for a Multiplexer we’ve already sold to BT, the schematics and BOM’s I will complete tomorrow (Friday) having worked on them over the past couple of weeks, with continuous changes to component values and circuit design, this is good as I’ve actually been able to show my worth. A busy week next week and continuing communication with Terry will ensure that a working prototype could be available within two weeks. Apart from work I’ve been a bit shitty, had a damn cough for weeks now, sometimes tickly, sometimes chesty. Coughing up lumps of phlegm every morning on the way to work is common, in the evening I become wheezy, almost asthmatic and cough till I nearly puke. Looking forward to Spring now, even though I love a cold winter, I’m growing tired of this coldy/coughy/wheezy shite going on non-stop.
