Numark PT-01 modding thread

[jeremy]

Thank you @rasteri

[JonnayP]

I don't know if this really counts as modding, but I'm looking to upgrade the stylus on my pt01 Scratch - anyone got any advice? I'm looking at European based suppliers. US to Europe postage isn't worth it and want to avoid China.

 

Also, anyone know if the pt01 Scratch ships with a saphire or diamond stylus?

 

Any help is much appreciated!

 

Thanks, Jon

more inspiration for all ya...

 

i also added little 20mm line faders to my PT01 - they are linear though - I kinda like the curve they're offering... they do fit perfectly into those 4 plastic thingys around the platter... One Fader was about 0,70 so it's no big drama to abuse em - I actually been rocking that pair for 2 years now and never did anything beside some cleaning spray (pressure air (?) only) ...

 

the buttons are for start/stop (PT01) and the other one is for stop on my RC3 Loopstation - or your MPC, APC... anything that supports a footswitch..

(replaced the 45 adapter with another speaker)

 

also.. how about a target light? the one I used was from a brand called Hollywood sth sth - way cheaper then a Vestax or Numark one...

 

missing stuff on the recent update is the rechargeable battery, the nanofader PCB for my Pro-X, a Shure M44-7 and the ultra-pitch + reverse-mode... hope to have it finished before the 7PT drops

 

can't wait til someone comes up with a solid solution to stabalize the platter... *sigh*

 

Hey man. I was just wondering what speaker you built into your turntable, how you did it and how it sounds. I'd like to get a decent speaker in mine, guessing sticking a speaker with its own battery would get the loudest results? A minirig wouldnt fit but something like that?

Cheers

Numark PT01 Scratch - Look Ma' No Cables! Modd

 

Hi, just finish a first prototype to a modd to the PT01 Scratch, basically is adapting an Internal Audio Source with USB Drive, SD Card, Bluetooth and leave all the original functions intact, so you could still use the original AUX-IN with it's gain and the USB transfer port for music transfer and iOS/Android DVS.

More important this hack now makes the PT01 Scratch a truly portable scratch solution, no phones or external devices need as a second music source, no more cables, no more draining your device battery, no additional chargers!

The idea is just take your PT01 Scratch and GO, kind of taking your book to read!

This first video is long as I wanted to show all the features in detail and the great solutions this is, secondly I was too lazy to do editing.

I'll post a second video and photos showing the device and the build, internals and connections, also I'll list here shortly all the parts needed to do this modd.

Second video showing the device I selected for testing, and a little about the immediate convenience that this modd brings.

I've been thinking about a way to add usb to my pt-01

 

what are those things called ?

They are called MP3 Decoder Board, it's a DIY board for projects, it will basically act as an intermediate board between the PT01S AUX-IN board and the PT01S Output board

 

Look for them in eBay as "MP3 Decoder Board" or "MP3 Decoder Board Bluetooth"

 

This is the one I got. http://www.ebay.com/itm/152278026152?_trksid=p2060353.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

The key here is to get one that has AUX-IN in a JST 3-PIN connector, here is where the original PT01S AUX-IN connector OUT will be connected.

 

I'll elaborate more in the build video and post.

Very cool.

[Diggedydave]

Hey guys! I absolutely love this thread and i think i´ve read almost every comment in it

Im new here and i want to do some mods on my Numark PT01 USB. Currently i´m working on a start stop button,

but i want to change it from latching type to the soft type as waxcutter explained in his post.

But my main question / idea is this: I still have a new "Pro x Fade" Crossfader at home which i won in a battle back in 2012.
Is it possible to get this crossfader in the inside of the Numark? If its possible, it should have a sharp cut-in...
@rasteri: Maybe with the nanoboard?

The Raiden Fader is not satisfying for me, cuz i don´t like the cut in time and it´s not smooth enough for my taste.
So i´m a rookie in the game, but like Djmadhatter, i want to try a lot of things, do it on my own and i´m not afraid of electronics, soldering etc.

Just need some advice!

Thank you guys! Big up for your great work and all informations...

Amazing stuff! Thank you for sharing this with us. Does this still allow you to control the volume of the source you're playing your Beats from? Also has it still retain the ability to plug in an external Source such as your phone as originally before?

[evil98]

Been lurking on this thread for a while, time to contribute.

 

This is my non-latching start/stop mod. Pretty straight forward. I utilized this relay module in place of the tone arm switch and a standard 24mm arcade button

I haven't decided where to mount the button yet but everything works. The relay is kind of loud but not that bad. I'm looking for a similar module that uses a solid state relay to avoid the click of the relay.

 

 

 

[Mutis Mayfield]

I love the madness clicking, it's addictive...

[Guest rasteri]

You could just use a smaller (quieter) relay, that thing's rated something like 20x the current of a PT-01 motor.

agreed, this is just the most common relay module off the shelf.

Yeah you control the volume from the decoder device itself for its sources, and yeah it retains the ability to plug external sources as before, including the USB to connect to your computer or to DVS software like edjing via mobile device

Elliot at Innofader modified a small batch of innofader PNP's to hook up to the PT-01 scratch turntable as simple as plug-n-play, only 15 at first but their next gen about to drop is going to have this option as a standard

I was able to use a fader plate to mark off a template from the inside where I wanted the fader to rest, cut a slit for the fader stem to push through, and drill holes for the fader to screw into, as well as counter sunk the holes so the screws wouldn't extend out the surface of the turntable. Next up I'll be skinning this via 12inchskinz to cover the original scratch switch hole as well as a heap of other mods that are popular in the portablist scene, as well as a few obscure ones I've been eyeing to do! CoolorCaps on the fader cap, Innofader inside, baby super seal red variant. Follow me on instagram at www.instagram.com/JAM1PHOTO

ground loop isolator is the key to eleminate those... those worked fine for me:

been using them in the pt01 and several DIY bluetooth speakers... it's based on a coil / galvanic isolation.

it's an average 2" fullrange speaker i snatched of a portable mp3 player. i hot glued it and wired it in series with the OG speaker...

Back in 2013 I did what you suggested - had a portable speaker with it's own amp in there but I went back to the OG amp because I had so many electric consumers in there that the pt01 got overloaded... there is so many cool shit you can do without needing any power... line faders, cue-option, ashtray...

Hey djlogix, I bought the sound interface that comes with the chinese voice over, found solution and it sounds english now~

Download this file (no virus) and save it to SD card, put it into the SD card slot on your interface, press MODE button few times till u hear BEEP BEEP BEEP BEEP, then power off and turn back on, voila~~

Im currently working on the contactless fader using IR slot sensor, found this with logic output so the respone is fast and sharp, 0.5μs max rise and fall times, not as fast as some of the others (some others with just 10nano second!!!) but Im very happy with that

Im still looking for a accurate circuit for the start stop button, anyone know any circuits for momentary push switch as start/stop button work with low current? Ive tried IC555 but its not very accurate, and will try to put a keyboard switch as the start/stop button, its lightly press force and tiny in size:

For a momentary switch start/stop you can use one of these Polulu boards (low voltage model).

https://www.pololu.com/product/2808

Silent and solid state. Works really well, the only downside is if you are also running an ultrapitch board this will make a speaker pop when you start the motor. Haven't bothered to find a fix for that. I just run it without the PWM ultrapitch.

Thanks Johnbeez, not running ultrapitch so thats perfect for me~

Is that the only solution? I use one in my car and it reduces the signal quite a bit as well as most of the low frequencies.

that's so cool, I was questioning my supplier about a fix or a solution and still I haven't heard back from them.

@djlogix

 

does your Bluetooth device have ground loop noise?

 

 

I don't want to say it doesn't need one because I haven't tested it on a Car, it probably be a good idea to have but with the wall AC and batteries is OK

 

It does not, all test with all devices is dead silince

It might just be the step down transformer i'm using that is causing all the noise. I'll look into find a unit that can use 12v to test.
