When you’re finished tinkering or fixing an electronic stuff. You have to reassembly it’s case. Now it’s time to put everything back together. Just screw the boards down, plug in the connectors, close the lid and you’re done, right? Well, sometimes, but not performing the reassembly methodically...
Recognize Major Feature of A Circuit Board
When you’re dealing with a Circuit Board. One thing you have to do is recognize it’s Major Feature. If you don’t know it, you will be ended up breaking it. Older products, including those with double-sided circuit boards, usually had components only on one side. Not...
Remove Components From Circuit Board
Once you’ve found a component you want to test, or one that’s obviously blown, you need to Remove Components From Circuit Board. Back when all components were mounted on leads pushed through holes in single- or double-sided circuit boards, removal was easy. A little solder wick...
Tinkering With Portable DVD Players
Never tried to tinker a portable dvd players? These usually have screws of varying lengths in the back. After you remove those, the back should come off, but make sure to have the unit lying on its face, because the laser sled assembly can fall out...
Tinkering With Digital Cameras
These are some of the hardest items to service. Most of today’s cameras are very slim and small, and the works are crammed in there tightly. Plus, cameras have lots of buttons, and some have sliding switches with plastic parts that fall off into oblivion...
Opening An Electronic Circuit Without Breaking
Once upon a time, getting at the circuitry of a consumer product was a piece of cake. Remove a few screws, pop off the back, and there it was. Providing access to the inner workings was a tradition begun in the vacuum tube days, when...
How To Use AirSnort to crack WEP keys
This article will show you How To Use AirSnort. As you know, AirSnort is a passive scanner through network. AirSnort can crack WEP keys. Up to 16 million IVs, in total nine thousand of 128-bit keys are weak. AirSnort can crack these WEP weak keys. You...
Own Made Automotive Diagnostic
The computers jammed (and later engineered) into cars in the late 20th century did nothing for the shade-tree mechanic. Previously, mechanics could make do with a shop manual and some oddly shaped tools. Computer-controlled engines, transmissions, and instruments, different in each manufacturer’s cars and lacking any...
Build Your Own Fish Tank Monitor From Kits
Given the design plan and science background in the previous section, all that remains is the engineering to build the monitor. The key selection parameters we used were: Cost Capability to simultaneously measure temperature, pH, and conductivity Ability to collect all three data streams independent of...
Sensor and Alerts For Fish Tank Monitor
Figure 1 shows the block diagram for the fish tank monitor. The design includes sensors for key parameters, including temperature, pH, and salinity (which we plan to measure using a conductivity sensor). The challenge in the design is (aside from finding the sensors themselves) to interface these three...
