Pico Crumble - Light Version

NEW - V2 adds better motion sensing, 4 swing and 4 clash sounds, and 9 more color profiles.

Owners Manual

- *No* SD card, and no changeable font. Simplification went with this option to allows a zero setup but more importantly no mobile parts so that the saber blades can be really smacked with no consequences on the HW.
- 2 font flavors, Dark or Light (only 1 per board)
- To make this possible, the fonts are also reduced / simplified : boot, power on, power off, hum, soft swing, hard swing, soft clash, hard clash
- Differentiation between soft and hard motions are actually based on the motion hardness to keep the experience as natural as possible despite of the reduced sound plurality
- Dimensions : 24x18mm, 4mm thick only
- Designed for Single Cell only (3.7V) like the Nano Biscotte
- 3 channels to be used with a 9W, multi-die, common anode LED, also like the NB, CS and Prizm (works with individual-die LEDs too obviously)
- Flash on Clash™
- 15 fixed color profiles
- Single switch (momentary only)
- Mute-On-The-Go to help with teaching or when you can't help yourself, turning your glorified illuminated stick on in the middle of the night.
- RICE-Edge™ to adjust settings when getting an "off-spec" LED
- same 2W amp as my other boards
- Header friendly (speaker connections at the rear, the rest on the other side)
- 10 bit audio
- same sensitivity, same motion recognition configurability and quality as PC/CS/Prizm with a blade impact anti echo etc.
- clash and swing motion flow limiters
- off delay APOP
- progressive ignition / retraction (of course)
- flicker / shimmer
- adjustable drive to remove the resistor in some cases
- enhanced deep sleep with 11nA consumption (I know you'd expect *PICO* Amp there if you're familiar with the metric system, don't you?). On a 2.6Ah battery, that's 27356 years of shelf time. For some reason, I'm betting the self discharge or natural dusting factor of the cell wil make it last less than this...
- Service menu to allow the color (re)configuration of the saber (read below).

Color Profiles
The goal was to provide an efficient way to get a saber configurable in blade color but not at the expense of spending hours configuring each saber. So, I defined 15 color profiles defined by having a dice either on or off. The Flash on Clash is the remaining di(c)e, so FoC always ends up turning all the dice on, resulting of a whitish flash if a RGB led is used.
In the case of a RGB LED, you'll get:

0   RED      1023   0   0
1   Orange      1023    255   0
2   Amber      1023   660   0
3   Yellow      1023   1023   0
4   Lime      340   1023   0
5   Lime2      145   1023   0
6   GREEN      0   1023   0
7   Cyan      0   1023   340
8   Light Blue   0   1023   635
9   Ice blue   0   1023   1023
10   BLUE      0   0   1023
11   Mauve      115   0   1023
12   Purple      355   0   1023
13   Pink      1023   0   1023
14   Crimson      1023   0   50

Service Menu
The service menu isn't really designed for the user but can be. There's no on the fly color changing with switch combos (well there's only one switch) and there shouldn't be any specialties like that provided to a young kid who ends with a color changing saber without understanding why his anakin saber is now purple :huh: Same for a teacher. It has to be robust.
Therefore, the access to the service menu is a long press (5-6 seconds) on the activator switch when applying power. If the saber was asleep, just press on the switch, otherwise, you need to either use the kill key (if any) or remove the cell.
You get a 3 medium tone beeps => color profile browsing with a beep each time you select. Allows quick reconfiguration of a saber that is red into blue. Not exactly a config menu for the user due to the fact power must be CUT then re applied to allows reconfiguration, however, remains simple enough so that it's a feature, not just a factory / manufacturing thing.
This was motivated by the situation of selling a saber at a booth in a convention and running out of blue saber but still having some red and green in stock. Factory menu allow to change this in a minute with neither soldering nor disassembling available. No quick connector swapping involved neither.

After selecting the color / profile, press for 2-3 seconds to validate, saber will reboot.

In normal operation, keep activator pressed for 2-2.5 seconds : 2 note melody, release switch, blade ignites but saber is silent. Press activator for 600 ms (fixed offdelay), blade goes off and poweroff sound is played, just like on CS / CF (indicates things are back to normal regarding the sound).

It's a card edge access to the RICE port to eventually tune a saber. Defaults work just fine (motion sensing etc) however you can get an LED that goes a bit off-specs (low Forward Voltage). As there's no color mixing per profile, the board uses Max-drive values : those are used in each profile. If a LED channel requires adjustment, you simply adjust that setting once, it will be reflected in all profiles that have the die on, or during FoC.
You can also adjust motion settings, i, ls, hs, lc, Flicker speed and depth, and pretty much all parameters like on a Nano.
The defaults have the max drive values all set to the max.

Booting - Deep Sleep
The booting process is similar to the Nano. However, when you insert the cell / apply power, the board won't produce any sound. A first press is always required to activated it an get the boot sound. After that, a second press will ignite the saber.
After entering deep sleep, the board will return to that first stage : a press will make it (re)boot. Deep sleep is hit after 5 minutes of inactivity (configurable).

Great sound board
If your looking for a low cost sound board, this is it. It is easy to wire up and It is tiny which saves room in a saber. I used the 28 mm bass speaker with this sound board and it sounds great.

Excellent Board
Color changing was never all that important to me, until I saw the Pico Crumble. I bought one for an Ultra Sabers mod, changing a stunt to sound, and I absolutely love it. The color change is nice, I wired mine up with a quad Cree RGBW, with only the RGB actually wired. Wiring was simple, though this thing is TINY. It was a bit nerve wracking, as I hadn't soldered to a PCB in over 20 years. But, I got it done and it works great. As it says in the literature, the sound is simple, on, off, hum, soft swing, hard swing, clash. One sound for each so, if you're a person who likes 8-16 sound files per action, this isn't for you. However, if you want simple sound and fast color change, with no setup other than wiring, this is exactly the board for you. I personally find the sound great and I love the color change, so I'm 1000% happy with this board.
