    The are specified to work with 5V supply but that does not mean they use LEDs with a forward voltage of 5V!!! Actually in the video you can see that you can go down considerably with the voltage,...

    I'm currently working on an Arduino breakout board called DIYino, which will be able to handle all 3 types of blade/lighting styles
    - HP LED
    - LED strings
    - neopixel

    But Erv's CF_LS could be...

    In the video I use the 60LED/m type, 50 LEDs on each side, i.e. 2 stripes attached and glued back-to-back, summing up to 100 LEDs.

    Although with the 60L type you are right, diffusing is a...

    If you supply these LED modules with 9V, you can only fry them.
    Come to think about it, Silver Serpent had a point there, probably the 9V battery could not churn out enough joice, so the voltage...
  5. LED string evolution - this will change the way we think about LED strings!

    Hi guys,

    I want to share a new and exciting LED string technology emerging. It has the potential IMHO to change the way we think about LED strings.

    Who did not dream about building one day an...

    Hi Plo Koon,
    I also have an RGBW in this build, but I did not wire up the white LED. Reason is, from RGB I can mix out every color I want, including a FoC flash. For sure adding white gives an...

    Hi ANorris,

    Please see the link to the Arduino Forum Thread above.

    As to the multiple switches: as it is, it's pain enough to accomodate 2 swicthes in any saber hilt, more that that is (at...

    Great to hear that people try such creative enhancement of the existing saber boards! Hope to see the outcome once finished, Keep up the good work! Cheers!

    Technical info:

    The board I designed supports the following features:
    - drive for 6 LED segments (Class II. or III. Serial) -> like MR/Hasbro or CF-LS (now I know why these have 6 segments, most...

    Glad it helped, usually the root cause is always the simplest imaginable (engineering wisdom).

    I guess no harm can come out of shorting the switch - and + terminals, because essentially the switch does the same. I also recommend having a look at the SD-Card and the battery charge.

    I would also do it like you proposed. I guess with 2 LEDs you are not crossing the 2A limitation, right?

    Solder bridge is metallic contact and therefore low resistive, so should be no issue. But overdrive of the LED's is. I usually go by the voltage rating, the reds I used for my Class III are rated at...

    FJK is fully right, if you want a smooth color mixing using the R.I.C.E., go for the Cex. Direct drive also gives you a smooth-like color mixing option, but with an offset w.r.t. R.I.C.E. GUI.

    Hi Buryaman,
    Good to see people doing their own electronics.

    Did you check that all LED's in the segment light up? Maybe some of them carry more current due to others not having a proper contact.

    Why buckpucks? If you have a PWM capable arduino board, all you need is a mosfet afterwards (preferably n-channel) and you can do the dim. Just make sure it has a Vgs threshold somewhere in the...
