Making Oxygen(first attempt)

Scris de sjackm pe iunie 29, 2009

Daca nu stiti engleza, incercati acest translator

OK so I decided to make a simple apparatus for making oxygen from electrolysis. I also made hydrogen during this experiment, but I didn’t collect it. The bothering thing was that it took 8 hours(!!!) to fill just a quarter of my small collecting “tank” ( which is a jar btw…).

Secondery products, in smaller quantities, were chlorine gas and , I think, Na that combined with water resulting NaOH. I’m not pretty sure about this though. I plan redoing this next week when I’ll make the anode( the electrode where the oxygen is producing) better- I’ll increase its surface.

But until then whatch the video :P . You’ll see at the final of the video what cool effect has oxygen over super heated wood.

Finally bought it !

Scris de sjackm pe iunie 24, 2009

I finally bought the Logitech Mx518 ! I’m very satisfied of it’s quality, even though it only has grip on the sides( I acutaly tested my hand on its plastic bag thing and lol, the surface has more grip than the mouse itself, but that doesn’t matter anyway).

It’s cool I can switch between DPI speeds , when I’m just using the computer normally I use the lowest DPI setting, but in some games I will want to switch to maximum, because it gives you comfort : I’ll move my hand on small distances rather than moving it on all the mouse pad surface.

It also has 2 side buttons that are useful and some games and I’ll usem them, especially in Garry’s Mod hehehe

Here are some screenshots with it ! ( and a comparison screenshot between another logitech mouse that’s designed for notebooks)

Some pictures

Scris de sjackm pe iunie 13, 2009

I made some macro-photos, if I can call them like so, with a Nokia 6500 Slide. It has auto-focus.

They don’t shine at quality, but they’re damn good for a phone.

Gmod contraption building … a stabilized car !

Scris de sjackm pe iunie 4, 2009

I like playing gmod again !

Here’s a thing I recently did in gmod :

This is a new creation of mine. I got bored of using phx over and over again so I returned to old-school gmod contraptions building.
So I made this weird car, with wirecontrol WASD, on an advanced duplicator.I added an RT camera for the rear view and a speedometer.
And I made a test ride. I loved how it behaved in corners, the drifts are quite awesome. But this awesomeness came with a price : some drifts lead the car to a barrel roll.
Solution ? I added a gyroscope, a less\greater than gate and if the car’s pitch is more than 40 or less than -40 , a thruster is activated and the car won’t barrel roll ever again. Even if it does, when it stops the power of the thruster will put it back on its wheels.

Home-Made speaker Test 1 !

Scris de sjackm pe mai 20, 2009

Hey all, I found a cool method to build a speaker ! Just search after “kipkay” on youtube, you’ll surely find it :P

And it’s quite cool too. This is what I did :

  • Made a coil on some scrap paper
  • Glued the coil on the plastic plate
  • Built some suspensions from scrap paper which will sustain the plate and coil
  • Put some magnets in the center of this coil while allowing it to move freely vertically

The result wasn’t as I was expecting, and I immediatly noticed the problem : the coil has a low resistance , meaning that it lacks of wire.

Well, anyway it had sound and also at full bass the plate was moving up and down, cool :D . At some point the coil began smoking. Here are some pictures and a video(smoking) with it :

I modified my case a little with some components. Know the red light that flashes when the HDD is in use ? Well, I deconnected that led and added 2 blue leds with some circutry. That’s because I wanted the mto slowly fade away.

Here’s the video : 

And here’s how to hook the pieces so you can do this thing too :

Settlers2

Scris de sjackm pe mai 14, 2009

For those of you who loved settlers2 in their childhoods, here’s a surprise !

A bunch of coders from Germany succeded in making settlers2 a multiplayer game. Not hotseat, but multiplayer ! Not only that it’s multiplayer now but it also runs smoother, runs on windows xp and the single player part of the game is a wip.

Here’s a link :  http://www.siedler25.org.

If you would still like to play settlers2 in single player, I recommend you to download DosBox. And here’s the full version of the game ( abandonware) on bestoldgames :

http://www.bestoldgames.net/eng/old-games/settlers-2-gold-edition.php

Happy gaming !

Thank you, youtube !

Scris de sjackm pe aprilie 30, 2009

Noticed the last update on youtube ? No ?

It was really frustrating until now to move the time cursor at an exact location. You frequently had the sensation that ” wtf, this video has only 3 or 4 spots where I can move the damn cursor”.

Well, youtube finally fixed that ! Now ,when you hover your mouse cursor over the timeline, the exact time appears, and if you click there, the time cursor will move at that exact spot.

Yay for youtube !

thanks-youtube

A aparut HD 4890 si la noi !

Scris de sjackm pe aprilie 9, 2009

A aparut HD 4890 si in magazinele noastre ! Pretul este de circa ~1000 RON.

Cititi aici un articol complet de testare a placii, pe site-ul CHIP.

Dupa parerea mea pretul este excelent. Daca in urma cu aproape un an eu am dat aprox 700 RON  pe un HD 4850, iar performanta a crescut semnificativ ( se spune ca 4890 cu 30 % mai buna ca 4870), pretul ma cam lasa cu gura pana la pamant.

Sunt deja disponibile in magazine, pe Evomag fiind prezente 4 tipuri Ati Radeon HD 4890, cea mai ieftina fiind aproape 950 RON. La 4890 scade putin si consumul fata de 4870, ajungand aproape la consumul lui 4850.

Daca vreti sa va luati o astfel de placa video, si aveti o sursa mai slabuta sau chiar no-name, va sfatuiesc sa investiti vreo 150-200 ron intr-o sursa decenta fiindca aceste placi sunt devoratoare de curent. Am rulat mai demult Furmark si , cum am wattmeter pe spatele carcasei , am vazut ca a crescut consumul de la 120 w la 245 W.

Daca sunteti pasionati de gaming, fuga fuguta pe site-uri si cumparati-o !!!
