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 *** earlier and we have new headlamp available in December, not in January. :thumbsup:
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 :huh:
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

So when we know what is inside, how it works ? Quite good I must to admit, but check yourself :
From brand new batteries :
From freshly charged NIMH's
Only 16% difference in led power in the boost and highest mode and almost no difference in lower modes. 700+ mA :twothumbs in high mode looks quite impressing compared to almost 300 mA that you can remember from Myo XP :thumbsdow. According to the manual - high mode (default 10 - 140 lumens) is unregulated, mid (default 6 - 51 lumens) and low (default 4 - 25 lumens) are regulated.
Ok, now some beam shots Myo RXP vs Myo XP :naughty:.
