USB LED Glow Stick Tutorial

Am facut un tutorial pentru un concurs in care se cere sa ai durata maxima de 30 de secunde. N-am putut altcumva decat sa accelerez vorbitul intr-un program, veti da pauza de cate ori vreti sa observati ceva in detaliu .

Din pacate tutorialul este in engleza, dar majoritatea stiti limba engleza

Making Oxygen(first attempt)

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 . You’ll see at the final of the video what cool effect has oxygen over super heated wood.

Home-Made speaker Test 1 !

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

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 . At some point the coil began smoking. Here are some pictures and a video(smoking) with it :

HDD activity LED mod

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

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 :

Happy gaming !
