Cleaning and drying a smartphone that has fallen into water: Eg. the NEXUS 5X


To repair wet electronic boards , like a mobile that has entered him water, as this Nexus 5X that, despite rapid action he took water by charging connector, speakers and hole cards, it is best use pure alcohol or distilled water and an ultrasound machine , in addition to rub with a soft brush on the visible parts (and still no full guarantees, as if you were running shorts could damage a chip).
If you do not want to complicate , and you have 30 or 50 € which typically charge for repairing these problems, better take it to a repair center phones with good professionals, you will leave no trace of water or debris and running (but do not light after the accident), or try the Waterrevive liquid (which works very well if turned off immediately).
But if the water has not reached penetrate into the metal lids of the base plate (where sensitive to interference electronics is hidden), we can obtain very good results without ultrasound machine with brush and distilled water or alcohol (alcohol It has the advantage that evaporates easily later).
Waterrevive : A couple of young Spaniards have developed a liquid that promises that your phone back up and running in 98% of cases, they say. This liquid (possibly alcohol, distilled water or other solvent of mineral salts) introduced displaces water (containing mineral salts) preventing depositing causing short circuiting. Using this system has good result if we turned off / disconnected the battery quickly, before the lime and salt is deposited. If that system will not work, you can try these indications (100% of cases so far) .

Repairing and updating a Lacie NAS (Fvdw version at Plugout.net)


If you have a Lacie NAS with a broken hard drive, it is very difficult to recover the Lacie firmware/partitions, but we can replace the HDD and install the Fvdw firmware version with this tutorial and improve its possibilities by the way.

Previously I explained several improvements with hard drives (NAS) I drive, Lacie brand with Linux firmware.
These small file servers have as main advantage that allows us to have servers of various types, in addition to files with very low power consumption (less than 10W in general).
The fact is that there is an alternative firmware developed improved from the LaCie sources that have compiled Plugout.net guys that we can install in our NAS, which greatly improved the performance of our network disks , adding possibilities as possible choose media server (ideal for home), NFS, VPN, etc servers and download torrent files, among others. And it also serves to revive the NAS if the hard disk fails, and see, step by step, the installation process.
  • Faster , it is having been optimized with the latest software versions, up to 40% more agile list of directories and copy files.
  • More reliable, uses file systems safer.
  • More complete , with all the features expected from a small server.

Changing the battery of your tablet for a few bucks

In this post we will change a spent battery to a 9-inch tablet
Currently it is not uncommon to see every family with an Android or Apple tablet, and over time the piece gets more wear of this useful accessory is the li-ion battery, especially if it is of poor quality, and when it lasts less than an hour we should change it, improving the original capacity if possible. In this case we have a Edertix Tablet 9.7" whose battery lasts less than half of its original capacity.

3D printing: Closer to the general public

Font
Since companies like Shapeways that can mail you printed the piece that your imagination is capable of creating up, like design your own jewelry in precious metals or plastics , 3D printing is becoming closer to being the next fashion, displacing the "smartphones" in sales.

How to expand the capacity of NAS Lacie Network Space

The LaCie Network Space is great for sharing files over the network
This tutorial applies to version 1 of the Network Space, but probably applicable to the (more rapid and complete) version 2 with little change.
I will replace its 500 GB SATA 1TB another, but it would also be February 1 TB (not sure if bear more capacity, but possible).
This NAS features low power:
  • Consumption of only 8W, completely silent without a fan.
  • Ethernet port with a maximum transfer rate of 6 MB per second despite using a SATA (somewhat limited in this regard because of its small processor) hard drive.This has been improved to 65 MB / sec. in the Network Space 2 with a more capable processor.
  • Ability to create users and access permissions to the shared folders, all managed through its web configuration page (also accessible via the Network Assistant ).
  • Very good price / quality; for little more than the cost of a hard drive, you have a NAS.
  • USB Port to expand its capacity reading systems EXT3, XFS, NTFS, FAT file systems.
  • And if you know Linux, you can access it and set various things .



Disassembling the Lacie Network Space NAS
In order to expand your hard drive before we disarm. This NAS, apart from a very proper design, no screws to release something we will have to help up as a screwdriver and some clips to go by releasing the tabs where the lid, as in the following image is secured.


A single turn split gradually inside the blue LED side bearing, since the other side carries the connections embedded.

Monitor your vehicle with Android Torque OBD2 reader and bluetooth


Today all cars bring a connection to the OBD diagnostic system ( most comprehensive in English) to connect to the control of the same, a small computer that controls many engine parameters and car electronics to improve consumption and seek mechanical (or user through the control panel) of the potential problems and maintenance required.
The vehicles are increasingly complex, and the fact that the unit warn you of these problems often prevents the operator hours of maintenance shop.
In Europe, according to Directive 98 / 69EG, gasoline cars from 2000 onwards, diesel cars from 2003 onwards and trucks from 2005 onwards must be equipped with an OBD.(Wikipedia)
Those who like "tinkering" with the car like me, to know it like the back of your hand, we can use this to read the status of the vehicle with a cheap bluetooth connector like the following image:

Adding a mp3 headset to a 3M hearing protection


If you are lucky enough to work in a factory with the times, surely ye be required to wear helmets as a image.

The workshop music rarely it gets, and even went down, between the noise and helmets could barely hear, but ... what if we add a mp3 to helmets?

Use this idea with responsibility; if you put loud music, maybe you do not hear a fellow warning danger.
A friend had the bright idea to do it, and here is the result.

What to do if you drop your mobile into water

First, stay calm and act quickly, take it out of the water and remove the battery, the chances of recovering a long time is decreased if the battery; internal short circuit could be damaging and irrecoverable watching it later.

Then it is best to disarm as much as possible (there are numerous online manuals how to disarm the different terminals) and give heat with a hair, but not too hot as to melt XD.
If you act fast, you will probably only get wet surface. Remove the battery, and if you see it completely dry inside, you can dry it with a hairdryer. You were lucky this time! XD
(This document was translated using Google Translator from the original spanish article)

Once disarmed (without battery or SIM and memory card and lost everything you can) you can opt for the easy solution, which gives a result most of the time, which is putting it in a closed rice for several days container, at least one week if you have not disarmed lot, or at least 3 days if you separate all the pieces, until it is dry. Rice is the desiccant (moisture absorbing) cheaper there.
