Answers to Some Technical Questions

We're just about there, to the 50 follower mark. That went much faster than expected. To those of you who have made it, congratulations and expect to receive a free sound board upon execution of the first batch of boards.

Unlike previous light saber sound board manufacturers, our aim is to provide plenty for everyone. Rather than create an intentional deficit to drive the price high, we will create as many as possible, keeping the price very low, and profit by the sheer volume. So... my hope is that will be better for everyone.

In order for this to work, we need as much support as possible. I absolutely CANNOT do this without YOUR support. I very much appreciate what so many of you have done to propagate this new blog. Thanks for the twittering, following, e-mails, and message board posting! Now... we need MORE. The more support we have the faster these boards will be made available. The design is on paper and prototypical circuits right now. It's not set in stone, so we are still eagerly awaiting more feedback, and we are taking all these comments seriously to make this even better than I alone could have imagined. My partner and I have a fairly large portion of the circuitry laid out and we will soon be fabricating the first boards. As soon as this is available, I will post many pictures.

As for some technical features. Many believe that power drivers in existing boards are severely lacking in performance. This is one of the many aspects of the LSD-X4 which will be revolutionary. The main power input will be able to appropriately and fully handle a wide voltage range up to, beyond 20 volts. We are shooting higher, but we will have to see how well this works in the finished design. It will be a switching PSU hybrid and will generate minimal heat.

Similarly, the LED (or other lighting technology) main output circuit, CMS - Color Mixing System (Special Thanks to Justin Polachek), will be able to drive three separate 10 Watt channels, by user programmable pulse modulation (MCP). Furthermore, each channel is software controllable down to a resolution of at least 1:256. allowing for a total color count of 16,777,216, a familiar quantity to graphics programmers- 2^24 or (2^8 )*(2^8 )*(2^8). The 10 Watt output per channel will be a reasonable max, but not necessarily the physical max. The LSD-X4's feedback controllers will produce very little heat compared with a linear regulator (the usual). Plus, with very accurate control over the exact current limiter's each LED will be driven with the stated amount, whatever the user specify's. I will let your imagination wonder a bit here.

Next, for button control... Some people like more than one button, some people like none. Some even still want mechanical latching buttons. To satisfy everyone, the user will be presented with typical modes encompassing several styles widely used in light saber designs. However, as mentioned in a previous article, there is no limit to the amount of modification employable with the LSD-X4. As a simple example, consider this. If the user wants their hilt to have three buttons, two momentary and the other latching and each soldered to S1, S2, and S3 on the circuit board (here S stands for switch) then with the LSD-X4's flexibility, the user would be permitted to assign functions in any order to any of these buttons. The latching button could be assigned the command of power on / off. The other two buttons could be assigned "change color to red" / "change color to blue" respectively (assuming the utilized a multicolor emitter such as a RGB LED.) So, well... that, and all the possibilities, are pretty awesome to me!!!, what do you think?

I hope to read everyone's feedback on these issues.

  1. One thing i'd like to see is some form of scripting for one momentary to change the colors or a menu system capability like Ultrasound, that speaks to you and lets you change all the options you want with the momentary switch.

  2. sweet im so excited about the CMS... ill talk with me friends and see if we can set up a program after we get the LSD to make the multi color pulse effect.

    oh and jesse alot of the stuff in the CMS paragraph even i couldnt understand :P lol. but hey it sounds like its going to be da shizzle man.

    man we got to 50 fast!!!!

    CMS is just going to be awesome. i was shooting for 4 pos output pads but oh well... im sure we can get everything we wanted.

    let me give you some more examples of the CMS capabilites.

    lets say we have the 10 watt RGGB fro LED engin... here what you could do. wire the two greens in series (allready is i thinh) and hook it to one of the three pads and set it to run 1000 ma and 7.4 volts. next hook the red and blue dies to the remaining two board and use the program to mix it for a brillinat purple. and then using the MCP wich i hope to have... set the purple to pulse slowly like every 2.25 seconds. as it gets brighter you could set the green to dim by lowering the current. the result you get is a two color saber. heck ya!!!

    also you could take and RGB and set all 7 colors to slowly transition... that would be trippin!!! make your saber a rave rainbow stick!!! i mean this board is going to have limitless options. i am very happy to have contributed. jesse you are the man!!!! cant wait to see some pics!!!!

  3. I like this purely because it is using the good and original ideas of the community to make a completely new and revolutionary board. Color Mixing was suggested for CF V5 but was rejected.

    I think that with many more people using RGB LEDs this board will have great popularity purely due to the fact that it can mix them. Go LSDx4!

    Now we've heard about the light capabilities, but what about the sound?

    ReplyDelete
  4. Excuse me did I read correctly?? FREE BOARD?!??!!


    THANK YOU!!!
    This board will be awesome.. Especially for the switch things and everything...

    I can't wait anymore...

    ReplyDelete
  5. BTW What would be the min. voltage of the board? If you can, please make it 3v or something so people can use 4.8v NiMh packs.

    ReplyDelete
  6. Triple post: Jesse, how do you know the right shipping addresses? Do you send some sort of mail to every follower when The "D-Day" is?

    ReplyDelete
  7. Quadruple post: BTW who pays the shipping of the boards?

    ReplyDelete
  8. One of my biggest complaints about existing technology is that sound control is based on tilt rather than swing or spin rate. Can the accelerometers be used to sense centrifugal acceleration, or is the 1G background too difficult to filter out?

    I really like the RGB LED support option. I have built simple analog color mixer boards, but I really look forward to not having to cram two boards into one hilt and drill holes for access to the pots.

    ReplyDelete
  9. To mati: we will contact the first 50 followers, prior to the shipping of the first batch, to verify shipping addresses. As for shipping costs, there has been no final decisions made About this. But I would imagine, if there are any fees at all, then it won't be higher than 10$ usd. Also, we have in fact been considering a step up voltage converter to allow the LSD-x4 to be powered by voltages which would not have otherwise been possible!

    To Jason: our goal is to provide a framework which will allow significant modifications to the original design. For example, what you'd be able to do is plug your x4 into a computers USB port, then using the provided software interface, use the computer to change the command flow of the x4 and accomplish exactly what you are asking for with the single momentary switch. Basically allowing you to write your own menu system with your own voice prompts, etc... However, this is not to say we won't be offering such functionality on our version of the design. Instead, if we don't offer it, it will be stll possible for you (or anyone else) to create it.

    To Scott: sound updates will come as a completely new posting next time. I will be going into much more detail with the ideAs we have in this area.

    Thanks everyone!

    And Justin, well have to get this 3 channel circuit revised to 4!

    ReplyDelete
  10. Another question about RGB support:

    Most RBG LEDs require a lower voltage for the red LED. I have compensated for this in my RGB mixer boards by adding a bias resistor. Can the maximum voltages be scaled per channel?

    Thanks...

    ReplyDelete
  11. yes every channel can be programed for different voltages and currents making for the most advanced and accurate color mixer in the saber community.

    and excelent! yes 4 channels. this will allow for a fourth pad to add the amber from the RGBA or for anything else you can think of. just more limitless possibilites.

    and yes sound will be discussed later on. once i know more on how to set it up ill be designing some fonts for it.

    so if you have any suggestions on fonts and or effects to be used, post it.

    i know I am personally going to be making an electrostaff font from EP III.

    ReplyDelete
  12. Two more considerations for this. 1: Upping the max mA output of each pads to be changed from 1000mA to 2800mA -- To allow for K2s, Lux3 Reds, Seoul P7s). 2: Auto-Voltage Selection like a buckpuck. If the LED needs more voltage to increase that amperage, just let the board do it. (Buckpucks can output up to input V minus 1V).
    3: Minimum Input Voltage: 3V -- 3xAAA (for MR replacements), 1x 3.7V LI-Ion (18650s).

    Any chance these designs can be put into the prototype?

    ReplyDelete
  13. well if you wanted more current you could porgram two pads to each put out 800 ma and 2.95 or however many volts and wire them both in parallel. series if you wanted more voltage.

    but i think with the limitless porgraming possibilites you could re route all current and all voltage to one pad if you wanted.

    as for auto voltage selection i think we might be able to incorporate that. but its also nice to be able to set firmly what voltage you want so you could better overdrive leds. like overdrive a blue P4 at 4.12 volts and 1313 ma. i mean you could set it to whatever you want.

  14. CMS programing option.

    you know how in some programs you have a giant color wheel or in that lightsaber app on the iphone you drag your cursor to wherever you want.

    i was thinking for a simpler way to porgram your RGB if your doing simple color mixing. is have just the huge color wheel in the program. and you could have your saber ON while you drag your cursor over the wheel and as your position changes in the chart your blade color changes in correspondace to your cursos position. hope that made sense.

    same thing with the lightsaber app just increase the blue and decrease the red... same principle.

    so this way you wouldnt have to go into the menu and manually say what voltage and amps to supply to this pad and what to supply to the next. let the program do that for you.

    what are your thoughts on this?

    ReplyDelete
  15. Lamina Atlas requires up to 7.9V @ 350 mA for blue channel; max Lumens = 98 @ 2.6W for green channel.

    ReplyDelete
  16. One last thing. Wi-Fi. I'd love to be able to program Wi-Fi access to this thing so that we could access it via a wireless network after the first setup.

    ReplyDelete
  17. But what is the "Basic" voltage that this board needs?

    ReplyDelete
  18. @ Jason: WiFi? It still needs to be able to fit INSIDE a lightsaber, you know.

    ReplyDelete
  19. I think that we would be getting WAY too fancy with all the WiFi things. The RGB could just use extra 3. switch.

    ReplyDelete
  20. If CF can do a bluetooth version that still fits inside, we can do Wi-Fi and one up them.

    ReplyDelete
  21. except everything that generates the sound isnt in the saber with Omnisaber (the bluetooth "CF").the onmisaber has the led driver and accelorometers (essentially) it transmits the accelerometer& clash output via bluetooth to a computer that generates the sounds and plays them through a sound system. the Omnisaber is more for live performance and demonstrations.
    the reciever can track and output sound for several omnisaber simutaniously.

    the hobby standard for size had become 1"x 2". and people are always trying to cram more in less space. greatly increasing the size isnt going to make this SB desirable. not everybody builds 19" hilts.

    I think Jesse has put alot on his plate of feature as it is. maybe you should wait for V1 before adding the kitchen sink.

    ReplyDelete
  22. correction - omnisabers uses RF not bluetooth

    its Hyperdynes wireless system that uses bluetooth

    ReplyDelete
  23. Yeah WiFi and all wireless systems can wait for V2.

    ReplyDelete
  24. im thinking so. we need to focus on power managment and the CMS those are whats going to make this board popular as well as sounds. heck the sounds are going to be easy. i mean it will support a wide variety of sound files. including raw.

    hey jesse did you know they make 16 gig MICRO SD cards? we need to use these. we can fit so much stuff on that!

    also i think for V2 if we go wireless we should make an iphone app for the color mixer. that way you can program it with your iphone!!!! how cool would that be!!! we would be the first soundboard with an iphone app. LSD X4 v2.0... theres an app for that!!!

    plus you could screw with your friend as he plays with your saber.... that sounded so wrong....

    ReplyDelete
  25. oh V3.0 should have voice recognition software.

    saber... ON


    giggidy.

    ReplyDelete
  26. The question is where do we get the sound fonts?

    ReplyDelete
  27. And how will this programming work? Will it be consumer firendly, or will we have to be software designers to change sound fonts?

    ReplyDelete
  28. @Jason: I know that there are a few people who are currently working on fonts, and I'm sure many more will be as the sound parameters are published here. I, for one am working on a 'Vader' font. I'm interested to see what people come up with.

    ReplyDelete
  29. Oh... and I would really love to see FoC (Flash on Clash). Seeing as people are going to be using RGB Led's we may as well include something to provide FoC... it was (and is) still very popular in CF.

    I would also like to see somebody looking at the capabilities of the board, looking at the most popular features, and creating a simple to use, but comprehensive configuration software.

    So say if the configuration was saved to a .txt file, the software would have a checkbox for Switch Pads 1, 2 and 3, and a momentary or latching option, and checkboxes for the most common commands for those pads, for example.

    Say you checked Switch One, Momentary, Switch Saber On, Switch two, Latching, When on turn saber blue, when off turn saber red.

    Then the software would change the config.txt file with those commands, and all it took was some clicking for the user. Of course, the more programming savvy users could use the software as a basic set up tool, and then change the code to their specific preferences. Thoughts?

    ReplyDelete
  30. I can give you an idea of the FoC using a 10W RGBA LedEngin LED.... the vids not great, though. The brightness kind of wiped out the colors.

    ReplyDelete
  31. any of the pads can be set to clash flash.
    as well as MCP. there will also be very advanced blade lock up sounds that i will be working on once i get some sound parameter info. and the programing of the blade lockup will also be top line. like if your using an RGBA we can go total strobe and have all the colors randomly flash when in lockup.

    ReplyDelete
  32. I have two things I would like to toss into the pot. They aren't any ground breaking idea, or anything like that, but if the LSD (we really should consider a different acronym...) is going to feature a blade flicker, like on the US or CF boards, can we please make sure that it pulses the LED BRIGHTER rather than switching it off quickly?

    That's the one thing about my US that's always bothered me.

    And my other great idea is actually better suited to a V2 or even an extra board. I've always wanted to make a "Rave Saber" that has a built in MP3 that can play the music through the saber's main speaker as well as saber sounds at the same time. The other half of that idea is that I always wanted to have an RGBA LED pulse different colors in time with parts of the music.

    For example, Blue for Bass, Green for rhythm, red for higher pitched sounds, etc. I know that's a lot to cram onto one board, which is why an additional board would be a killer idea.

    (I actually think I sent Novaconceptions an email about this about a year ago...)

    ReplyDelete
  33. the board will proobably have that allready on it. and you could set each color to flash when it detects a certain sound frequency. shouldnt be to hard. but yes the blade flicker will be a brighter pulse. not a reduced pulse. it can also be mixed.

    ReplyDelete
  34. All sounding great...I do wonder about the balance between voice/switch control and the removable SD/microSD card route. I find each to have significant advantages.

    for FoC effects and an RGB set-up perhaps one of the colors could be set to brighten as the clash effect? That might be an interesting effect to see.

    interesting comments above...and responses.

    ReplyDelete
  35. Re Nightguy's post above:

    In the prequels the point of contact between blades flashes yellow. IMHO the red and green LEDs should flash, but I don't see why it couldn't be a user-defined option. There could even be a routine that could flash or flicker different channels in sequence, as someone suggested before.

    ReplyDelete
  36. Well generally FoC is white, but I have seen green blades go blue and many others, so it is really down to the user and what he/she likes. And has anybody thought of accent LEDs? I believe that CF v5 will have 7.

    ReplyDelete
  37. the LSD as far as me and jesse have discussed, will have 8 for a complete chasser system. but its possible this might now happen. where has jesse been anyway? i havent heard from him for like a week now. maybe more.

    ReplyDelete
  38. I like the idea of multiple leds for colour mixing.
    1/ are we to expect to choose a clash flash too?
    2/it might be solved with able to use a latching switch, but I always thought that the power off on some boards is too long to hold down a mom button. Could this be user define > than the time required to enter into a blade lockup/blastre block, assuming we are getting this too Jesse in the LSD-X4?

    Please, please, please.
    Cant' wait for some youtube vids mate

  40. So far I like everything I've read. I specially like the multiple buttons feature and the flexibility afford by them. This is something I've wondering about for a project I have in mind. Happy to see I may have a direct solution.

    ReplyDelete
  41. I agree this all sounds great, but very often hilts are very stretched for space. I mean unless you're a really good sabersmith you would have a hard time fitting 5 accent LED's inside a hilt, let alone 8!
    And also a hilt can become clumsy with multiple switches. 3 to me is one too many, even if you can change the colour. I would prefer to do this in software on a PC or a menu system in-hilt. I like to use all of a board's capabilities to a maximum but I think that sometimes having too many can stretch things, and you pay for something to use only half of its features.
    I really hope that a lot can be achieved with this board even when using the bare minimum of its features. Take the Ultrasound for example, it was never in such high reverence as CF is, but it was still in reasonable demand because it could look (and sound) great with only one sound font and 2 accents!

    ReplyDelete
  42. Just had a really good idea! Obviously in the movies there are multiple ignition/retraction sounds. I know that some boards do have multiple sounds for this, but they are not controlled in the ones I have seen.
    Say you were really mad and you swung your lightsaber while igniting it, it would play the classic ROTJ pneumatic ignition. Say it was still during activation, it would play a slower, gentler igntion. Likewise, if you were to power off your saber in... let's say, frustration, like one of the characters does in Balance of Power 1, it would play a quicker ignition, and a longer one with no movement.

    Any thoughts?

    ReplyDelete
  43. Great idea skott! This is something I want to have in the board!

    ReplyDelete
  44. Yes great idea! And so, I will see to it that it has this ability!

    ReplyDelete
  45. Hooray! I got an idea onto the board! How far along are you Jesse?

    ReplyDelete
  46. By the end of the day I am hoping to send off our cad files to have a proto PCB fabricated. The design should be flexible enough to allow software changes if there are any problems present. Fromt there, a lot of programming will start happening, both for the device itself and the computer side interface. This proto board will allow me to finally post some pictures and videos!

    ReplyDelete
  47. Too awesome..

    Systems overloaded...

    ReplyDelete
  48. Ok, 2 more ideas.
    1) I'm not sure if this is what Justin meant in the first comment here, but for pulsing... instead of dimming the LED like on US, if you use an RGB setup, then pulse the LED to the next color. I.E, If green add slightly more blue as pulse to cyan if it is a 'low bin' green, or slightly more red to pulse more yellow if it is a 'high bin' green.

    2) I think there should be an option to be able to play audio tracks behind the saber sounds, even when it is off. So you select The Imperial March, for example, and when you pull the kill key, it plays the boot sound, and then starts the Imperial March, and you can turn the saber on and off while it is going. My thinking is that you can also play sounds like rain, battle effects, etc. while using the saber.

    Thoughts?

  49. as a avid saber builder , me and many others i can think of would greatly appreciate a item like this, glad someone is taking this on - its impossible to get hold of other boards and the prices are often ridiculous! be very stoked when these are availible, im already spreading the word with other saber builders and so far the response is great! look forward to completion of this product!

    ReplyDelete
  50. Wow, just wow. I'm speechless of the amount of time you have devoted to the saber community. I assume I'm speaking for all of us when I say that what you are doing is absolutley amazing. I am new upon the saber scene but I do know basic and C++ very well. I would be happy to offer any assistance if needed, tester, guiney pig, board maxer outer (workin on an 80 watt saber right now - hopefully will be brightest ever), or whatever you need I will do. I always love the spirit of openness and I'm glad you are bringing that to the table!!!!!
    Thanks - Rogue Rotkosky
