Software Defined Radio IC Decap: R820/RTL2832U
Software Defined Radio teardown: R820/RTL2832U Decap Recently there has been much interest in two integrated circuit which were originally designed to receive FM radio and DVB-T TV (as used in Europe). Some enterprising people quickly realised that since they were based on software-defined techniques they could be quickly re purposed for all sorts of clever […]
LED candle effect: Tear down and decap of a controller
A teardown video from Electronupdate: A dollar store item which implements a flickering candle effect using and LED. A look at the technology: linear feedback shift register or ROM based? Let’s decap the controller and take a look at the silicon die to find out! More details at Electronupdate blog.
AVR decapping
Here are some examples by manekinen of what can happen when an apparently high reverse voltage is applied to several AVRs. Via Hack a Day.
