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) .

Adding hot bed BQ Hephestos 3D Printer: Compiling and installing new firmware

If we want to print in ABS, heated table need

There are instructions on how to do this on the official website of Spain BQ, but are outdated and only explain how to do it in version 1.4.2 , which differs substantially from the latest firmware more refined versions , such as 2.3.1 or 2.4.0 ( do not not try it with 2.4.0, it gives compilation error at the very beginning).

Well, in short, I will show how to compile the firmware to serve you for these and subsequent versions , with optional hot bed activated and working properly. But first, I show how I've ridden (and there tutos on youtube so I save this part - The guy in this video , although physical and clothing clavadito me, not me lol).

A clause ... is a company of the stature of BQ should have precompiled firmwares with different options , and let the user choose (even versions with height sensors for self - calibration table), it is outrageous that a user who does not have know anything about compilers, have to eat the head ... even though deep down that is when you ride a printer that whole piece yourself ... but it is a trifle compile and save many headaches (there are several threads forums questions about this topic).

Before anything else, apart from the table, cables and thermistor, to feed the table need a power supply of at least 12V 8A ( best of 11 or more); the more heat amps before the table and more easily keep you warm. The most economical and reliable is to use an old power source ATW at least 300W, by looking at the indicating amperes for connection + 12V, are durable and well refrigerated fan:

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.
