Humble Bundle

Hi guys, today I'm posting about a site I found really interesting: humble bundle.
In that site you can pay 1$ a game like "medal of honor warfighter" or 5$ "battlefield 3"
A part of your money will go to a charity, another to game developers and another to Humble Bundle Inc.
I hope you enjoy that site,

Blender depth of field and RGB curves test

Hi, today I'm simply posting a test of depth of field and RGB curves in blender.
Maybe in the next days I'll post a tutorial for these features.
Here is my render:

Blender trasparent texture

Hi, today I'm here with a simple but really useful tip: using transparent textures on planes (but also other meshes) in blender.
First of all I wanna say that I discovered this method here.
I'm working with blender 2.66 but I think it works fine in 2.5x or higher.
Here is the final result:

To reach this result follow these steps in order:
1)create your plane (or other mesh)
2)create a new material for this object

3) active transparency and set alpha value (optional: also specular value)  to 0

4)in the texture panel create a new texture and set as type "image or movie"
5)load your image
6)under Influence tick alpha and leave its value to 1.0

7)Optional: to make the image fit the plane: under texture panel, in image mapping set "clip" instead of "repeat"

8)Now it you try rendering you will see that shadows made by your plane aren't of the same shape of your  texture; to make them follow your image you will have to change settings in the object that RECEIVE the shadows.
In the material panel, under shadow, tick "receive transparent".

Cockroft Walton voltage multiplier

A cockroft walton voltage multiplier is a circuit that increase the input voltage.
The circuit is made by stages and each stage is made by 2 diodes and 2 capacitors.
Here is a schematic of a 2 stages voltage multiplier:

I used IN4007 diodes and some high voltage capacitor that I found in a printer power supply circuit; however i reccommend ceramic capacitors with low capacitance and about 3kv of max voltage.
Here are some photos of mine 8 stages, 5kv, cockroft walton multiplier:

Here is a video:

Base Filtering Engine: "access is denied" restore tutorial

Hi, today I'm here with a quick tip that I found useful.

Here is a step by step tutorial for solving this problem:
-download this 2 files: file 1 , file 2
-double click FIRST firewall.reg and THEN bfe.reg
-restart your pc
-open "regedit"
-go to HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>services>BFE
-right-click on BFE and click permissions
-check that for "Everyone" is enabled "full control" and if not, do it

-open "services" and now try to start BFE

If you have done everything in the right way it should start.

Small diy electric motor tutorial

Hi, today I'm here with a tutorial for creating a small electric motor.

First of all you will need:
-a power source (5v or more)
-some tape
-some wires
-some NON-insulated wire
-some magnet wire
Most of sites suggest to buy it on online stores but finding it is easier than it seems.
In fact most of windings of transformers or inductors are made with magnet wire.
I took my magnet wire form inductors in a printer power supply circuit.

-a quite strong magnet (I took it from a geomag)

Construction:
-Use your insulated wire to create 4/5 loop coil of about 1.5 cm diameter like this:

-Use a knife to cut insulating layer from your wire, at one end of your wire cut all insulating layer, at the other just half, like this:

 

cut insulating layer with a knife

 -Use pilers to model NON-insulated wire to create two supports like this:

 -assemble everything like this:

Making it works:
To make it works, put the magnet near the coil, and plug the two supports to your power supply.
The hardest part is calibration, don't give after 2 minutes, just try making adjustments to the coil or the magnet.

Here is my motor working:
