(How to) Wifi Dish Antenna (part I)


Ever wanted to build a wifi antenna out of a satellite dish antenna?

It all started with a donation of this dish, old, forgotten and rusty.

I teared all apart, sanded and grinded all rust away.

Bought this spray can:

This is the result after painting:


This is the antenna link I am basing my idea. Also look at this links:

Simple arduino+breadboard idea

PSince I am startin to experiment with arduino and I breadboards are a must: 

Here a basic idea using:
•one cd case
•screw supports from a motherboard

A simple cd case, just need half of it.
I sticked the breadboard and the 4 four screw supports from an old motherboard.

All mounted ready to experiment.

How to Refurbish an original gameboy


Gameboy original
My old gameboy, the jewel I dreamed of as a kid. And finally, I bought this 2nd hand gameboy, and really used it ... after all the commercials I've seen, I got mine..
Time passed (this one is dated 1989), so it needed a refurbish. I read a lot about restoring. Here the steps:

1. Disassemble the GB


This is the worst part. Taking apart a gameboy, has its tricks, the greater are the triwing screws. The simple way is to get a screwdriver triwing (http://dx.com/p/large-triwing-trigram-screw-driver-6154), but there are two options:

Alternative A)Use a flash scredriver:



Alternative B) Make a triwing out of a pen:


Tried both, ended with using a flat screwdriver
My attemps


The disaster I made

I used bothe screwdrivers, one for getting the screw out (the first and hardest part) the other just to take it out.
The are 6 screws on the back of the case:
With patience and the links from above, you can figure out how to do this. The insides screws are cross, so no problem there.

2.Open Gameboy

Once open , need to separate de LCD ribbon, you will end up with this two sides:
Front 
Back
After son screws: simple, start collecting plastics, to do the washing.

3. Washing

Get all the parts, and soak them into hot water with regular soap. Use a brush.
Before front

Before back.



4. Sulfated battery connectors 

Simply use water and soap. If any remains use a nail file to take the rest out.

5. Replacing parts

Most old GBs have some damage parts, mine only had the LCD screen cover, founded at amazon. http://www.amazon.com/gp/product/B002J9R2LA/ref=oh_details_o01_s00_i01?ie=UTF8&psc=1 other GBs have other parts to replace, see links below.

6. Re-assembly

Put all the parts together now.
