LED Ball

I found this on youtube and I think you should watch it too. It’s lovely. And innovative. And I like the effects !

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 :

School Project Uploaded !!!

I finally finished uploading the school project, which is the project I’ve worked hard on. It’s called Pupils&Their Hobbies and it’s telling stories about a few pupils in our school (GRI SUNCUIUS), including me !!

I was the video producer, so that’s why I’m posting it on vimeo and on my blog for easy finding and viewing.

Here’s the link to it ( Videos-By-Me) :  VIEW PROJECT

I had to split the project in half because vimeo won’t accept video files greater than 500 mb for a free account .

M-am ars

M-am ars cu peroxid de hidrogen . Cam asa arata o arsura de peroxid de hidrogen ( la mine e mult mai mica) :

Am aflat dupa net ca H2O2 ingheata la o temperatura mai joasa ca H2O si m-am gandit sa cumpar niste apa oxigenata si sa o bag intr-un pahar la frigider. Ok, dupa ce am scos-o , am observat ca intr-adevar a ramas o pelicula subtire de lichid la suprafata ( pentru ca apa oxigenata din comert are doar 3% peroxid de hidrogen )  .

Si ma gandesc eu … cum sa testez daca e concentrat sau nuuuu ?????? Si bag eu degetu ca zic ca n-are nimic in atata apa .  Nu am simtit nimic. Am ramas deceptionat … frate si m-a pus dracu sa ma scarpin pe nas cu degetu ala ( suprafata mica din fericire) . Dupa care vad ca mi s-a albit unghia. M-am sters repede ) . Dar dupa un timp am simtit o caldura puternica pe suprafata aia mica pe nas. Si alb o ramas acolo =)) .

Acu ma gandesc sa iau vreo 3 flaconase de apa oxigenata si sa fac niste peroxid de hidrogen pentru niste experimente. Un flacon de 170 ml costa 3 lei . Si o sa incerc sa fac ceea ce se numeste “poor man’s liquid nitrogen“ . Dar la chestia aia nu se mai poate gresi cu un deget. Pentru ca a doua oara nu mai ai deget . ( bine , nu stiu daca pot face asa ceva deocamdata, nu m-am informat complet).

In alta ordine de idei, ma apuc de electronica inapoi. Simt ca explodez daca nu fac ceva. Si cu leduri sau ceva . Orice, numai sa fac ceva . asa ca vreau sa-mi cumpar ceva piese si un multimetru digital, eventual un letcon fiindca e mai bun(cred) decat un pistol de lipit traditional cu sarma de cupru).

Daca va plac chestiile astea DIY ca si mie ( foarte mult imi plac) , cautati pe youtube dupa “kipkay”.

Are multe videoclipuri DIY tipu’ , unul l-ati vazut deja mai jos , cel cu bateriile la laptop .

Si in final, mai spun ca fac ceva research-uri si ma documentez despre condensatoare. O sa incerc sa-mi fac si o butelie de leyda . Si sa strang cat mai multe condensatoare la aceiasi volti ca sa-i leg in paralel si sa obtin o baterie ( care ar tine macar vreo 3 minute aprins un led) .

huaaaa, mi-e somn . pa pa ©

Motor dintr-o bucata de sarma si magnet

Am incercat sa fac un motor dintr-o bucata de sarma, magnet , curent electric desigur si niste agrafe de birou. E cam fail, dar macar am reusit sa-l fac sa se invarta.

Dupa ce fac rost de un magnet cilindric incerc sa fac un motoras calumea ( e doar pentru amuzament, am eu destule motorase acasa ). O sa ma mai documentez . Chestia asta functioneaza prin inductie magnetica ? ( de aia o sa ma documentez )

Bun venit pe blogul meu !

Salut , imi pare bine sa vad ca am vizitatori deja . Blogul e in “constructie” . Adica trebuie sa-l finisez , sa-l fac mai “custom” .

Nu pot sa spun exact pe ce teme se vor axa articolele mele . E greu de spus ….  Dar hai sa vedem pasiunile mele mai intai ca sa va faceti o idee :

• Natura si Spatiul ( nu prea le am cu cunostintele dar imi place sa citesc despre ele )

• Stiinta ( pot sa categorisesc putin )

1. Electricitate
2. Calculatorul ( lol , ceva normal )
3. Aproape tot ? =))

• Imi place mappingul de half-life 1 dar in ultima vreme am lasat-o mai moale din cauza ca mi-am luat o placa video Ati si am probleme cu hammer editorul
• [EDIT 27 septembrie 2009] M-am cam reprofilat pe Source mapping (hl2 )
  
• Jocurile ( cui nu-i plac ? …. )
• ETC …..

Deci articolele mele se vor avea teme de gen DIY ( sub forma de tutoriale ) si “prostiile” care le fac eu …. umm “experiente” cum imi place sa le numesc
