recently, a client told me that he was experiencing fuzzy and distorted pictures on his samsung led tv whenever he switched on the light, in his living room. it was found that the ceiling light was emitting rather strong emf (electromagnetic fields) and disrupting the display signal on his tv. solution is to change the light to an LED light which in research has proven […]

whether you are a mac or windows user, backing up data is viciously critical and may be a life saver. losing data due to failed hard disk can be very costly if you need to recover your lost data. no preference over mac or windows, both are just as vulnerable and fragile, but windows 10 machines seem to be improving over time. so as a […]

this tool change the settings and protect your privacy, just click and use the recommended settings, reboot your machine after. download it here, it’s portable so that it does not install files in your windows if you are wary of the source. https://www.oo-software.com/en/shutup10   the second tool i like to recommend has nothing to do with your privacy but to protect your windows computer by […]

Apple just dropped the bomb that they will be using their own proprietary chip instead of intel processors for future apple computers. one of the reasons that i can think of is just beginning of the year, flaws were discovered in the intel chip architecture that allows hackers to mine user’s information out via the intel chip. and thinking that intel actually design an “apartment” […]

after gathering information from uncle google, this is what i conclude: there is no need for iphone to run an antivirus app. first of all, iOS from Apple has their built in security mechanism and secondly, apple does not allow outsiders to intrude into their iOS to meddle with their proprietary security mechanism, meaning antivirus companies are unable to build security apps meant for iPhones. […]

every household has a circuit breaker but that is not good enough, you will need a good power board with surge protection to prevent your electrical devices from damage. a fuse in the circuit breaker protects against overcurrent. Its purpose is to prevent fires, and it protects against faults on the equipment side. A surge is an over-voltage. A surge protector protects against this overvoltage. […]

according to the article enclosed, a good power supply is critical for long term stability and reliability for your personal computer. i believed this is also important in all electrical power driven systems. choose a PSU that is high in wattage preferably double what your desktop can output quoted from the same article below: “All about output Manufacturers usually list their power supplies’ output in […]

the one reason for unrooting smartphones is to recover data(files or pictures) lost or deleted by mistake. after unrooting the smart device, you will not be able to do software update or google pay. to revert the pending action, you will need to unroot the device. at such, unrooting android devices seem tricky as there are many apps or software, some require you to pay […]

To determine what would happen in a circuit if a component fails, re-draw that circuit with the equivalent resistance of the failed component in place and re-calculate all values. The ability to intuitively determine what will happen to a circuit with any given component fault is a crucial skill for any electronics troubleshooter to develop. The best way to learn is to experiment with circuit calculations and […]

the enclosed links described the boot process of a computer, this is the fundamental of computing. if you think thru the process when a fault happened in your computer, you can quickly identify the what is causing the fault in most cases. https://www.tldp.org/HOWTO/Unix-and-Internet-Fundamentals-HOWTO/bootup.html   https://www.webopedia.com/DidYouKnow/Hardware_Software/BootProcess.asp
