Please Welcome the NANO BISCOTTE v3

[erv]

no, it should be on the battery itself. But you can use a PEX to drive it, with the its remote hooked up to the DS pad

Hello! First of all thank you for your fine work, thank to your boards I'm ejoying this new hobby big time 

And second, I have a litle problem with my NBv3 board. I had it working as intended, and ready to be placed into the saber. I had to stop the project for few months and when I asembled it into the saber it stoped working properly:
- When I pull the kill key the 2 blue leds instantly light up, even before I "ignite" the saber
- The sound effects and the flash on clash still works
- I dissambled the saber and tested again, so a shorcut from the metal case is discarted
- I checked the voltages of the NBv3 pads and while idle (kill key pulled out and light and sound off) the high power led L- is almos equal (if not equal) to ground. So, if I am not wrong something is not working properly in the board since voltage on the HPL L- should be way higher so the leds don't light up.

Is there any further test you could think of to confirm it is damaged?

Thank you in advance.

you either have a bad wiring of your main led di(c)e but most likely you fried the main driver.
Did you use a resistor on the blue and if so, what value ? Did you measure your LED forward voltage Vf.

[DaHecky]

The resistors are like 1,2 ohms 3w so I think was pretty safe there.

The fried driver seems the most likely reason. I also measured the voltages with no leds wired, just measuring the pads and the conclusion was the same, the L- had ground value... :(

Do you think I can send it to your repairing service or should I look for a new one? It's quite sad since the sound and the FoC still works :(

[erv]

you can safely replace your driver with a Si2302

[DaHecky]

Thank you for the help and swift response :)

I will see what can I do, since it seems a finer job than what my thick solder iron can handle 

If not I hope I can use your repair service.

Thank you again for your amazing work and the way you treat your clients!

NP happy to help!

Does progressive Ignition mean only for LED-STrips or is it a slow ignition of a normal LED?

[erv]

this actually rather concerns the Nano Biscotte v4 (and no V3). The v4 has scrolling extension on ledstrips. On high-power led, the effect is (partially) simulated by having the light climbing in the blade.

Ok I have one more question and I hope this is the right place to ask. I formated my SD card and did everything like in the manuual, but when I when I switch to my self-made sound font, the bootup doesn't work, the poweron does and the hum aswell as swings and clashes don't. I tried a lot of things already but I just don't know what to do now :/. I hope you can help me.

your sounds simply don't comply with the board requirement (sample rate, channel number etc). Also, some software like audible generate wav file with incorrect headers that aren't supported. The best is to author your file with a standard (and free) software like audacity.

[Pyron]

Ok thank you. What channel number for example does the NBv3 need? And is there a tutorial or something for that?

Thanks for your help :)

[TAKEI]

Hi, wish to ask can NB V3 install LED strip like NB V4?
Or NB V3 is not possible due to limited hardware/programming?

Thank you.

[erv]

you need a V4 for this, sorry

[TAKEI]

It's OK. Thank you for replying,erv.
I will try to grab 1 when JQ Saber restock.

Thank you.
