Can find all these on amazon

Can find all these on amazon.com now

Any updates on kick pedal input for drums I have had no luck in finding this accessory.

Does anybody know if it is just 2 poles in foot pedal input (short 2 together to simulate pedal) or is it more complex ???

Thanks Tim

I pulled it a part after looking at photos already on here :) thanks :)

 

It is a standard 3.2 mil stereo plug (3 pole) if you short the common pole to the left pole of the plug get kick drum sound if you short the common pole to the right pole of the plug you get a closed hi-hat sound. So just need a box with two momentary push buttons.

 

Keep you posted on how it goes :)

Any updates on that momentary switch for the drum set? I can already jam out with just my fingers, but it would be too smooth to have foot pedal access too.

Levi, I'll start working on a simple pedal that one can make an will post a DIY thread on the subject. This will be a somewhat cool project to do.

 

I'll let you all know when I post the thread here.

Sweet! I will be looking out for it. I think I might have some other musical equipment that I can use to make these switches (Boss switch pedals). Thanks!

By the by... saw Paper Jamz guitars in BigLots this week.
Kind of surprised to see them there so soon. That's usually the 2nd tier channel that typically gets product at the tail end of production.

Jax - I too can't wait to see your pedal mod. I have one of the drums and would like to try and make a pedal too. Would make some of the playability a lot easier.

Hey ya here's what I did

Hey ya here's what I did using a lead with a 3.5mm stereo plug on one end and a pair of RCA connectors on the other, then fitting a mating RCA connector to a box (500mm x 300mm x 70 mm). I then connected 2 heavy duty momentary push buttons in parallel across the right channel of the RCA socket(this gives you a double kick pedal). Next was a third push button in parallel with a guitar effects foot switch across the left channel of the RCA socket - the push button works just like a normal Hi Hat pedal and the foot switch enables you to "lock down" the HI Hats just like a conventional Hi Hat quick release clutch (for playing closed Hi Hats and double kick at same - ie, for playing heavy metal or "Blue Monday" by New Order). I dont even bother with the one onboard speaker as the unit sounds sooooo much better plugged into the hifi. Will send pictures once i have neatened up the box and slapped a coat of paint on it!

Hey, that's awesome! Can't wait to see how you did that. I can't figure out why they put it there but haven't yet made the foot switch in the first place. They haven't even mentioned it or shown it in their ad videos.

Whew... okay, I'm back,

Whew... okay, I'm back, apologies for being so busy, however now that I have a little bit of time, I'll throw a few things out myself that ya'll might find interesting... I've noticed that with my drums (I have two, red one on the left and a black one on my right. then I just sit two guitars in the middle of my little 'jam table' facing opposite directions & laying flat, with three amps. The wife says no more, even though I can tell she's impressed when I play them all together... and I need just two, perhaps three more amps, but we'll keep that between me and everyone here for a few days before they just kind of appear, Where's-Waldo style... Hey, they're pretty cheap, multi-functional and one of them I use to play my own MP3's through as I'm not fond of the 'scratchy' songs in the units themselves. Back on drum topic, if you haven't got one of these and are entertaining the thought of snapping up one, remember to keep the protective plastic overlay to keep your drums working for as long as possible. I think you can even play through it, if you never take it off and leave it factory-applied fresh looking.

Ah, those elusive pads, what to do, what to do to let one use drumsticks instead of their digits...? Personally, I prefer using my fingers but if someone is just hellbent on sticks, you can get a portable USB PoweredDrumkit, which uses sticks, from here:

http://www.lightinthebox.com/index.php?main_page=advanced_search_result&...

for about 15$ (*grinning sheepishly* - I did and they should be here any day now...). But for those who wish to traverse their own path with the only their WowWee drumset and some sticks, I have noticed that nearly everytime one of my insulated speaker cords will make the drums work (especially the large bass drum due to it's larger surface area), as the coiled wire slides over both the drums' and the guitars' touch capacitors, if that helps any.

For anyone who wants and must just have that high-hat mod option, I'd suggest using an old Playstation -or whatever brands- racing wheel's accelerator foot pedal, that'd work great for an app like that...

Right now, I am playing around with DJ Mixmaster to see what kind of stuff I can come up with do synthesizing everything together.

I'll attempt to take/toss some pictures up once I have a bit more time...

By the by... part 2...

I did see the amps at BigLots this week. They were on a toy section shelf, not near the guitars, which were hanging on the toy section rear wall.

The guitars didn't interest me, but an Amp might be useful for giggles connected to my laptop at the office.

so, after week 1 of "getting

so, after week 1 of "getting to know" the home made paper jamz "double kick/hi hat extension module" I found the heavy duty push buttons to be quite squeaky, clunky and slower to break the circuit than to make the circuit. By substituting them for industrial micro/limit switches (pizzato mv17-these are far more responsive) the unit becomes much more playable, time will tell if these switches can handle the punishment associated with being part of a real pretend drum kit. This switch has a 13mm diameter roller at the top of its plunger which should work well in conjunction with a basic foot board/pedal and thus giving the system an even more realistic feel/playability. The hi hat lock down switch works a treat but I found the "foot area" became too crowded with this extra switch in place (it was fitted as an after thought). As there is plenty of room inside the actual paper jamz unit I shall hard wire the switch in the front or side based on whichever is easiest to reach while playing. Stay tuned!
Tim.

While it is true that Paper

While it is true that Paper Jamz are just toys, even some toy guitars enable consumers to simulate "real" guitar playing (playing notes, fingering REAL chord shapes, etc.), even if they don't stay in tune too long. WowWee should have taken more time to develop this product to actually simulate real guitar playing, and maybe they would have a winner. Cap sensor technology has so much potential, but WowWee failed to really maximize it, settling instead to make a quick buck. Development costs would have been higher for sure, but sometimes you have to spend a few extra clams to get some positive output. Simply put, WowWee jumped on the "fake instrument" bandwagon that Guitar Hero made popular a wee bit too late. Even Rock Band 3's "fake guitar" controllers are apparently set up to mimic guitar strings and fret boards.

Hello All,

Hello All,

I bought a Paper Jamz Guitar, Amp, & Strap combo set for my 7 year old son for Christmas recently.

We're having a problem with the Amp, as the sound volume is extremely low when the guitar is plugged into it.

On the otherhand, when I plug my MP3 player into the Amp, the sound quality and volume loudness is fine.

Does anyone know how to adjust the Amp sound volume when the Guitar is plugged into it? We desparately want it louder!

Any helpful comments will be appreciated!

Okay, I was able to solve the

Okay, I was able to solve the Amp volume just now.

I just jiggled the jack that goes into the Guitar output/headphone hole, and now the Amp sounds loud. I believe the Guitar output hole is slightly defective. The audio cable is fine as it plays my mp3 songs perfectly fine on the Amp.

Also I just found out that the Amp volume is controlled by the unit plugged in (guitar, mp3, etc.)... However, we had it already set on loudest high volume on the Guitar.

I suppose we'll just have to put up with the testy Guitar output hole as I paid only $15 for the entire guitar/amp/strap combo set at Walmart during their latest Black Friday sales. And I will undoubtedly never be able to find another new combo set at this super low price.

I'm hoping my comments here may help others who may be experiencing the same volume problem with their WowWee Paper Jamz products.

But in the end, my lil son (and his 9 yo sister) are rockin out and lovin this set! It's been very fun for them both! And they look sooo cute playing em too!!!

To quote a musician: go procreate with yourself.

Just because we're buying these doesn't mean that we can't play a real guitar, or that we can't afford a real guitar, or that we even bought this to use as a real guitar.

I got mine to hack. Quite frankly, the "song" features were really disappointing, but the freestyle mode lets you play it like it's a piano, or as if you are only playing one string on a real guitar. It's actually quite fun for me because I can't play guitar for real: I can only pick notes.

But I've already taken it apart and am documenting the schematics and such and don't even "play" with it the way WowWee expects half its end users to. LOL!

On the topic of disassembling, though, somebody needs to take pictures of the teardown precess, including which screws go where. When I put it back together, I was missing one screw in one place and yet I had seven left over. ???

Jordan, since you have already ripped it down why did you not take some photos durring this process? LOL You could have posted them here instead of someone else. I have already posted some ripdown photos but not showing where the screws go..

How far have you gotten with the schematics? are you going to post the final schetch? Also what type of hacks do you plan for this?

So many questions!

First: I didn't take pictures because I could always tear it back apart and take pictures then. I have never ever had problems with forgetting which screws go where, so I'm really beating myself up right now. That's why I wish someone else could do it, because I can't figure out which screws go where....

I'm mostly documenting the schematics of the inputs, and I'm doing it in my head ntil I can get it figured out. Something is wrong, though, I'll take some pictures and upload them to show what I mean.

As far as posting the final sketch of the input mapping, I will definitely do it.

Lastly, I was expecting a different sort of multitouch interface, similar to a normal touchscreen, where it sees the entire thing as one area. The Parer Jamz, unfortunately, see a bunch of buttons, basically, and they are activated my electrical charges rather than pressure. Oh well. Frown

sorry to chain reply.

sorry to chain reply.

 

You might notice, in the second picture, the ribbon cable. It just gets pressed up against the PCB's contacts. However, as I mentioned earlier, I have been working on the input schematics.

 

The first picture here shows how the ribbon cable connects to the PCB. It just moves up and to the right, no rotation necessary.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This second picture is the schematic showing which contacts are used by the sensors on the guitar borad.
Note: I only have this guitar, it may be different on each model. Sorry if you can't read the tiny labels, they say Strum, Strum, Mute, Vol., Mode, and Demo.

Notice that the contact on the far left is "unused". In debug mode it is fully functional, which raises the question: are all the chips physically the same, and just have different limiting software on them for each guitar? If so, maybe some guitars have an extra fret that is used by that last contact. If that's the case then it might be possible to gain access to every song from just one chip, but that's purely hypothetical.

 

Please also notice that the frets' contacts are in reverse order, so the "first" contact would be the extra one at the end of some guitars (theoretically). Having the contacts arranged in such a formation makes it easy to do this.

 

Debug mode is interesting. Think about overlaying the frets over the contatcts in the proper order, except it goes from the first contact through to the last one; the second-to-last one has a random beep that sounds like a generated tone (555 timer or something). All the other fret-contacts (in debug mode) produce individual notes, scaled from the left to the right, so it's obviously tested in debug mode before they attach the front (with the frets and cable) while at the factory. Either that or it's opened back up to be tested and then put back together, but I somehow doubt that.

 

Debug mode contains a note for each contact but each note is different, which is another thing that makes me think you could get that extra fret. (It's actually more fun to play the debug mode than the regular "freestyle mode" because at that point it's like a giant multitouch piano. :D

Tika, do you think maybe we need to get Peter to either ban xboxmaster or close this thread. I am sick of the spam lately. Now it's one user :( Peter can't just close every thread though.

Every day I check the site and always see xboxmaster has posted something in the recent posts. I don't get to see someone else anymore :( It's either SPAM or just a single comment like "cool"

Jaime, I agree. I think Peter will see this though. I know he'll do something about it. I agree he probably won't want to close every thread.

Jordan - that I2C looks to me to be some kind of I/O controller, like for disc drives but instead for this particular application maybe a bus type thing. I don't know much about that type of hardware though. Maybe that is what is used to send signals from the touch-pad on the guitar to the main CPU board?

Jamie
Jamie's picture
Tika, I forgot to mention I

Tika, I forgot to mention I know quite a bit about I2C. It is a digital signal and uses pins labelled SDA and SCL. SDA is Data and SCL is Clock. It is a 2 wire interface and SCL (clock) is used for timing. An example is my compass uses it on my backpack :) Seems the touch pad on the guitar is like a compass (it transmits when you want it to or in a time) the touch pad might be I2C. So if you hold a "string" in the guitar the CPU board would time the signal using SCL to come in very fast. Then the SDA (data) would transmit data to the CPU board and the board would then play the sound that equals to the key pressed.

How many wires does the touch pad have?

That sounds cool! Jordon is trying to figure out the electronics of it. I long since tossed out all my Paper Jamz stuff as I didn't see where I'd do any PJ hacking. I rather stick with robotics. :)

But the touch-sensor stuff does sound interesting! Maybe it can be hacked to do single-string notes too?

Just make sure and plug the headphone jack all the way into the output port on the guitar, for some reason they can be messed up and they don't go all the way in at first.

I just noticed that WowWee now has a pro model of the Paper Jamz guitar.
It has the interesting feature of being able to load your own songs
and different guitar sounds into it.

Does anyone know anything about how the songs are processed by the app. to load into the guitar?

What format are those .pji instrument sound files in?
