Here is some very interesting reading related to the obvious buzzword of the year, The Internet of Things. This article series I was tipped to take a look is about embedded firmware hacking and reverse engineering of an IoT device, a TomTom Runner GPS Smartwatch. Hacking Smartwatches – the TomTom Runner, part 1 article introduces →
A solid state relay (SSR) is an industrial component used for interfacing low voltage control signals to high current mains voltage loads. The SSR may be designed to switch either AC or DC to the load. It serves the same function as an electromechanical relay, but has no moving parts. You can control SSRs easily →
The RSA SecurID authentication mechanism consists of a “token” — either hardware (e.g. a USB dongle) or software (a soft token) — which is assigned to a computer user and which generates an authentication code at fixed intervals (usually 60 seconds) using a built-in clock and the card’s factory-encoded random key (known as the “seed”). →
RSA SecurID is a two-factor authentication device. It gives out number that change depending on the time, and correct number is needed to log-in to sensitive systems (=one-time password functionality). RSA SecurID 700 is a small key fob that connects easily to any key ring. Here is front panel of RSA SecurID 700. There is →
This old IBM SCSI hard disk was built in kind of strange way. I am just wondering why… →
I have previously tested Qi wireless charging receiver model Universal Qi Wireless Charging Receiver Kit For Micro USB Cellphone.This Universal Qi Wireless Charging Receiver Kit For Micro USB Cellphone a about a size of a credit card and ultra-thin in design. It is designed so that it could be installed inside cell phone – or it →
Here is teardown of one failed power supply. What is inside Two 6.8 uF 400V capacitors had failed and burned the mains fuse. Good design that it was well protected. But again the failure was bad electrolytic capacitors. This device was not worth to repair. →
This is a tear-down of one TT6061A based touch dimmer that could not handle touch and failed (static electricity killed it). This dimmer module manufactured by Eaglerise was found inside a desk lamp. Inside view The construction inside looks pretty OK. There is a proper normal fuse there (tiny ceramic fuse) and also over-temperature protection →
In my earier posting LED tube replaces fluorescent I wrote that due real Fluorescent lamp fire danger I have pretty much tried to get rid of potentially dangerous tradtional starters in the fuorescent lamps. So I replaced the starter with electronic safety model – if bulb does not start, it will stay off without heating. →
Will the fancy new tech in the S7 be as cool as it’s cracked up to be? Only a teardown will tell. https://www.ifixit.com/Teardown/Samsung+Galaxy+S7+Teardown/56686 Posted from WordPress for Android →
