Tech Work

Wednesday 17 March 2010 at 5:18 pm

Been repairing a LOT of laptop’s recently, Mostly Virus/Spyware related breakage. To which i do the only sane thing, and flatten it and reinstall. Unless I’m told specifically that they need X and Y off it, then i pull out the ole trusty USB->IDE cable with my spare 80Gb laptop HDD, and the ole 16Gb USB key with my linux install on it.  Really can’t go wrong with that, fire it up grab all the files and then proceed with flattening.IMGP0063

People ask why i don’t just remove the offending software, I never really have a straight answer. Mostly for me is because it just saves time. I don’t really want to spend a whole day removing virus’s and spyware from someone else’s computer when i can spend 5 minutes starting a fresh install. Plus well I don’t repair computers for a living, so when I’m doing it its as quick and painless as possible for me. Mix in the fact i never really trust a install that's been compromised anyway. Occasionally i will just do a quick repair, but its has to be for very specific reasons. Mostly like i don’t have the install CD’s required with me >:D

So if your looking for me to repair a laptop take note of these points

If you have something you want kept SAY SO, don’t just assume i will.
If you need X software reinstalled after too, please tell me when giving me the laptop. I can’t read minds… yet.

That's basically all i like to know.

Plus one last note on the subject, if i say i don’t want anything for fixing your laptop/computer. I really don’t want anything.  If i think the repair was worthy of getting paid for. I’ll freely say how much you owe me.

The attached image i thought was fitting, G’s Buzz Lightyear’s “Laser” stopped working. and it was me doing a quick switch for a new LED. Seemed fitting somehow.

 
 
 
 

Well that month passed

Wednesday 13 May 2009 at 02:21 am

Previous month passed by rather quickly, I never did get to the point of releasing any of the stuff I'd programmed. Mostly because i haven't been playing any subscription games at all lately. Its been refreshing actually. I finished both assessments, One of them i was finishing off with hours to go before the submittal deadline. Purely my own fault too, i just kept putting it off and putting it off. And suddenly the deadline was upon me. But they're done and both passed. Got 2 assessments left on the computing course and that's it done for the year. Basically finished one of them just need to cleanup the written parts and format the code. Other is a multiple choice paper, which I'll do in the coming days. Then its 100% focus educationally on the mathematics course till October when i start the next computing course.

 

IMGP0153 I did make some changes to the cramped computer room, I added some shelving. Trying to work out a way of adding more actual desk space without cramping my movement room to much, but i have some ideas. I'll get round to it, The shelves alone gave me plenty of room to move, and they're well out the way of the two smaller people i live with. So its not so much of an issue right now as it was at the time of the last post. Still haven't built G a computer area yet, but i really want to take a decent amount of time on that and do it 100% correctly and make sure it'll last as long as the ones I've built for myself at least.

 

On the project side, I've been making some headway. Collected a metric ton of research materials and schematics, started slowly building up my parts inventory too, Checking over my current equipment and see what needs replacing/updating before i really get started in earnest. Nothing worse than starting something and having to stop to wait on a part or something to be delivered. There was a lot more to learn though than I'd actually considered, So it may take a bit longer than I've estimated to myself but that's not going to stop me! Its just a matter if finding a good starting point, or even several starting points. Once i get those i'll rush onwards.

 

On the coding side for the above mentioned project, I do love C#, but when it comes down to it I'm still i Delphi man, and its hard hard work to not switch back just due to how easy i find good ole Pascal to use, especially when it comes to breaking completely new ground for myself. But i think I'll soldier onwards with C# anyway.. or maybe a bit of both depending on how it all goes. Getting ahead of myself here anyway.

 

Anyway, its damn late as i write this, so i think I'll finish up right here.

Busy Month Ahead

Monday 06 April 2009 at 5:59 pm

clipart0196 Yup, as the title states April is going to be a very busy month for me. Got 2 assessments to start and finish this month alone, and both are due around the 25th too. So I've got to get onto those. Throw in the fact that Garion's at home most of the month too due to school holidays, means its definitely going to be an exciting time. Plus we're actually working towards getting G into school for a whole day too. All of which just means more distractions.

 

On top of the two things mentioned above, I've also recently "Finished" a little program that displays the latest Eve-Online Wallet entries on my G15's LCD. So i also want to fire on through and clean it up, remove unneeded/wanted processor usage and just overall make it more presentable and fire it out there into the ether and see if anyone uses it. Knowing me this will take most of the month also. Been working on another little "for fun" project too, Takes your twitter feed, and you can link your friends to Xbox-Live Profiles and it takes there avatar and displays this right into your desktop with whatever they've said, or said to you. Kind of a nice little visual Avatar group/conversation. I know, it's a kind of pointless program and serves absolutely no useful purpose. But i don't really care. Its something fun to-do. I'll get around to posting screenshots of both of them at some point this month also.

IMGP0078And now the real project that I'm going to focus on through the summer/autumn. Radio and Computer interfacing. As I've mentioned before Amateur Radio is a sort of hobby of mines. Its always drawn my attention and imagination. And finally I'm in a position where i can actually do something with this interest. It's going to be fun, for me at least. So expect more on this through the summer months especially when my first course wraps up in the next month or so, which will give me some more time to devote to it before i start the third in august. Lets just say that i wont be buying any prebuilt equipment beyond the power supply which i already own and there will be a lot of computer interaction with it. I dare say this one is going to be a long haul project, but I'm eager and excited and willing to learn whatever it takes to get to where i want to be with it in the end.

 

I'm also going to be hopefully doing some more work within my current house, my small computer room has been great. BUT! I'm quickly running out of room in it and that's just with my course materials, which I'd hedge a bet and say are only going to be getting more plentiful as the course ramps up in difficulty through the years to go on it.  So i need to start thinking of shelving and some more actual work space. as you can see from the recent picture its getting pretty cramped. Maybe move the wall, or remove the wall and replace it with a half height partition. Either way, something has to be done about it. But i still feel the need to keep the equipment separate from the rest of the room.  What i really need is a larger house, but that'll come! Also need to plan out and build a decent computer area for Garion. He seems to prefer a full sized desk and chair these days over the smaller ones that are more aimed at his age.

 

So that's my very rough plans for this summer and what i want to get done. Isn't as much on that to-do list now that I've written it all down. But course I'm not taking into account all the good weather were sure to get and the endless afternoons of sitting in the garden with a book basking in the sunshine. *wonders if its still sleeting outside*

 
 
 
 

Laptop Repair (Acer Aspire 5000)

Saturday 03 November 2007 at 10:02 pm

Recently my laptop broke internally. The little circle PSU port inside went, the pin inside somehow snapped of the motherboard. Course my laptop is out of its warranty at this point by a few months (Typical ain't it) so i decided fuck it. it was broke anyway with no way to charge the battery ever again so i couldn't break it any more than i already had. So i decided to dismantle it and make the repair myself.

I managed to repair it successfully, and if you want to see how the repair went then please click to read this entire entry. as i don't want just any idiot stumbling along and finding how to dismantle there laptops.

But before all that, let me include this little disclaimer, you try it. and you fuck it up. Its all your fault. Don't even attempt to come crying to me.

random today

Friday 20 July 2007 at 7:21 pm

I've encountered a few things of intrest on my usb searches, Especially the numerous embedded processors out there with USB capabilities already built into them.. i think this one is an especially good path i might follow down further. I also liked Shadee's idea in my comments from the previous entry too. Both viable options.

I noticed on the news earlier that england is suffering from quite bad flooding once again this year, Glad i dont live down there. The extent of flooding in this local area has been the same as every other year.. about 1 inch of water covering the road by the train station. But as they say, Look on the bright side.. I doubt they'll have a hosepipe ban this year.

Potter mania has sweeped the nation too *sigh* (oo i wonder if this is why shadee has gone offline for a week!) With all sorts of rumours surrounding what happens at the end of the book. Personally who cares? why try to ruin it for yerself and everyone just buy the damn book and read it.

Anyway, I think im going to make myself a Electronic Weather station. Might be handy if/when we move up to Skye (Hopefully soon), Know cos looking out the window just doesnt cut it these days. And to go with it im also going to build myself a new PC before we move, Im still leaning towards AMD and course 64-Bit and it'd be kinda pointless at this stage not to go dual core. So that kinda limits my choices right there :D Probably a AMD Althlon 64 X2 6000. And stick with Vista course.

I found this free Searchable PDF creator on my travels in cyberspace today, No idea why i was even looking for it but i was. Supports Vista x64 so yay.

Updated the Links section of this front page, Split them up a bit. Removed the Images and just generally cleaned it up a tad, Also made the comments easier to identify on the individual entry page. I'd never actually noticed before today that there was no seperation between the bottom of the Entry and the First Comment. I also stole Morduun's Libary link he found and posted on his blog a while ago. Course using my own books instead, Well the ones that were within reaching distance of my computer anyway.

 
 
 
 

USB and PIC's

Thursday 19 July 2007 at 12:46 pm

So while doing some quick research into building my own USB devices on the cheap (Hobby), I've noticed something. There isn't really a cheap and quick way to-do this. No wonder most hobbiest stick to Serial or Parallel, these don't require extra money or extra knowledge to use. Now when ya thing about it, USB was designed to replace these technologies right? So why didn't they think about it when they started. why make it so hard to actually just knock something up and plug it in and just have direct access to it, Take the parallel port, no fancy drivers required just a case of accessing the correct memory location to send/receive over basically whatever pin on the port you wanted. Simple and it worked.

But needless to say i haven't given up, Instead of trying to design something that i can just reuse and rebuild in everything i make from this point onwards. I've decided maybe it'd be better to design some sort of separate interface. That you can just plug your boards into. Now there's probably like a million of these out there i haven't really looked into it as yet. I may even borrow ideas from other people. But I'm thinking I still have old Serial/Parallel stuff about, and I'd kinda like to be able to use them without having to really re-invent the wheel. So why not a USB Interface that can also handle Serial/Parallel as well as having room for anything new i work on in the future. From a driver stand point this might be a nightmare and beyond me, Cos if you've ever tried to make drivers for Windows then you'll know that there isn't really a lot of good reading information out there about it. And most of the communities on-line are just a tad on the unfriendly side to new people.

The electronics sites I've encountered so far are quite the same I've noticed too, or they just look so bad on the screen that you never stay very long anyway. I'm sure I'll find somewhere that i seem to enjoy within all this eventually though i always do.

As far as the game's programming, Still havnt really produced anything of note just messed about with XNA. Its the language you see C# is nice but its so close to Object Pascal that i find myself writing in pascal then have to debug forever. Guess its just something i have to get used to. I know Microsoft are supposed to be releasing XNA 2.0 Soon, and the additions look very good indeed (Funny side note, i didnt find this information on a XNA website, i actually found it on the Pascal Website). Im just hoping they finally release a x64 compiler that you dont have to fight with Visual Studio Express to use.
