Throw in a Rigol oscilloscope, an Arduino, and a few multimeters for good measure.

The model used is the HERP Nursery II, also known as the BCR-25 Wine/Beer chiller and Pie Warmer.

EEVblog #70 – Turn your Rigol DS1052E Oscilloscope into a 100MHz DS1102E (Hack)

The ingenious EEVblog viewers have finally cracked the Rigol DS1052E Oscilloscope. All you need is a serial port cable and you can turn your 50MHz DS1052E into the 100MHz DS1102E.
Dave shows you step-by-step how easy it is, and that it does actually work.

Rigol caught with their pants down AGAIN!

NOTE: There have been a couple of reports of units failing when this mod is attempted. The cause is unknown at this stage, but the exact sequence of serial commands keys appears to be IMPORTANT. You CAN’T hit backspace or ENTER etc, follow the instructions precisely, key-by-key. The vast majority have had success though.
As with all hacks, do this mod at your own risk.

UPDATE: This mod no longer works with firmware 2.04 and above. You have to downgrade the firmware first. See the UPDATE VIDEO.
