Hi all :wave:,
A good friend of mine wrote to me about modding the Proton. So I
suggested a CR2 cell since it has higher capacity and small but I have to
find out if it's possible or else he would let out the magic smoke. I haven't
been playing with it because of its' flickering but now it's time for some
action.
I also have to add that this Proton was given to me by a highly respectable member.
I am not sure why a Proton, maybe he wants me to do some 'research' with it.
So I defeated the red loctite, this is what I get...
A circuit in a capsule... little white tactile switch for show
Splitting the capsule, reveals the boost chip and the mosfet?
The RED lead connects to the RED 3mm LED, it is connected directly to the microcontroller.
The boost chip is the Linear Technology LTC3401 3MHz Synchronous boost converter. With a 5V max input operating voltage.
And behold the rather odd looking green pill inductor..
Odd as in, these axial encapsulated 'chokes' are usually used for filtering purposes.
I was feeling quite let down at first especially the presence of the huge SS14 Schottky diode but readon...
A custom Microchip PIC, interesting...
Removing the tactile switch reveals the custom PIC chip
So I did some probing... probably a 3.3uH 10%
Thats 28mOhm, a lot better than I was expecting
Although the inductor has a very low dc ohm, I am not sure what is the max current it will do.
In case if you are wondering, the equipments are calibrated yearly to NATA standards.
Unfortunately for nekomane, the circuit does not work beyond 2.5volts.
The microcontroller was doing crazy stuff, switching between leds, won't switch off and etc.
I'll continue my research when I have more time.
I should also admit that I am very inexperience in electronics. I know it's a simple circuit but
it's something interesting for a $69.95.
Thanks for reading, have a nice day.
