Petzl Myo RXP - review
Hello boys and girls charismas is coming so you need to know that to buy for a present ? These year Petzl move his lazy corporate ass earlier and we have new headlamp available in December, not in January.
(Today it may look a bit strange, but it was originally posted on December 2008 ) So, the good old Myo XP revision 3 looks like that : From outside, they only change the color, again… But there is nice orange inscription over the collimator “Regulated – Programable” oh yeah So what they change inside ?? Good old temperature-sensitive resistor in the foreground, but in the background there are some mayor changes. Nothing unexpected, the SSC P4 U1SW0H star, also better than Myobelt XP that I get yesterday, there was only T2 star. Some closer look on the PCB : After removing some glue we have a winner of this content : 4K FLASH 256B SRAM 20SSOP Cypress Semiconductor CY8C24123A-24PVXI microcontroller . http://download.cypress.com... So when we know what is inside, how it works ? Quite good I must to admit, but check yourself : From brand new batteries : Код:
