    I was having a thought of adding a new ultra pitch solution. something that wont prevent me from playing a 12" on the pt01.

     

    Would the best bet to be install a knob on the side of the table? Is that possible?

     

    Is there another solution other than a knob or fader/slider for ultrapitch on top/face of the pt01?

     

    I use a button but its a non adjustable ultra pitch. Essentially I switch between to sets of resistance. I've removed the stock trimmer for the 33.3 speed and replaced it with a break out board with both the stock trimmer and a new trimmer with a different resistance. Then I use a relay to toggle between the two.

     

    If you do the battery mod, you have more then enough space to mount the potentiometer inside the battery compartment. That way it could be hidden but still adjustable.

    I started messing around with my focus fader but im not even sure if it is a working fader or not. I gave V+ 5v, metered both VC and I get 5v no matter if there is something blocking the interrupter or not. Is there anyway to check if the interrupters are bad?

    Anyone use a PWM DC motor speed controller for their pitch? I ordered one from amazon and its awesome but some reason it doesn't work when powered by the batteries. I removed it and went back to the resistor method but I want it to work.... plus I already drilled the hole for the knob haha.

     

    The module I used is here https://www.amazon.com/gp/aw/d/B010JNKFKM/ref=yo_ii_img?ie=UTF8&psc=1

     

    im thinking that its the minimum voltage (6v). I believe that the motor runs at max 6v. This is the one I tested and it works but very inconsistent rpms at low speeds https://www.amazon.com/uniquegoods-1803BKW-Controller-Adjustable-Driver/dp/B00RYKR83Q/ref=pd_sbs_60_1?_encoding=UTF8&psc=1&refRID=K9TXZF5VWMAC0G24MAY2

    The battery leads bypass the voltage regulator so you'll be fine.

     

    oh interesting, i've been running my 3s lithium pack from the leads. :o

     

    so far nothing has exploded lol... but maybe ill move it

     

     

     

    Would a lipo be a better battery type for use instead nimh rc packs or lithium 18650 cells?

    18650s are normally lipo too. Either will be fine.

    So I made one 8.4v nimh pack and installed with deans connectors..seems to be running fine. Could I run 2 of these packs parallel at once to double the amperage but keep the same voltage?

    I also have a couple 18560 battery sleds that I'm going to put deans on to try 2x18650's since that'll put the pack at 8.4 as well..

     

     

    2 packs in parallel will keep the same voltage but I'm not positive that is the best way to go about it. With lithium batteries I usually do a series of parallel groups, but this is because I need to be able to monitor the voltage of each group to charge them safely. I'm using a 3-series over charge/over discharge/short protection board and 6x 3000mah 18650 batteries (3 groups of parallel the put those into series = 12.6v 6000mah).

    Will a 9.6 battery pack (ni-mh rc car type)be too much voltage to use in the 01 connecting through the battery leads?

    Thats fine, the voltage regulator can handle up to 18v.

    Is it better to solder directly to this piece, to the actual battery lead? I also see some people using 12v batteries.. I can make either or battery pack...

     

     

    I used the battery leads. Whatever is easier for you

    Ill be ready to part it out as soon as the new mixer gets here and I can verify it works as it should. Hopefully middle of next week.

    I would prefer to just send the entire board to you and let you use that or pull parts off you need. I'll let you know as soon as I'm ready to go.

     

    Sounds good thanks

    I grabbed a 61 off ebay. If you have issues finding the pots you need let me know. I'll probably be parting out my 56.

    Got outbid. Not willing to drop more than $75 on a busted mixer in that terrible condition.

    Yea I don't blame you that 56 was in really bad shape. I still need both the slide pot and rotary pot. Let me know when your parting and how much. Thanks

    Hello my friend, could you send the 3D layout for printing the housing to innofader mini?

    Speaking of mini Innofaders. I've been working on a fader housing for the PT01 scratch. This is a test print using the mini Innofader. Need to make some adjustments to the design but its close.

     

     

    Hello my friend, could you send the 3D layout for printing the housing to innofader mini?

     

    Hello, It is currently not available for download. Maybe down the road but not at the moment.

     

    Here is what the final version looks like though.

     

     

     

     

    Has anyone tried to add a volume fader on the PT01 that would override the current volume knob? I had an idea to add one just above the cross fader switch. Here is an image to show what I mean. I haven't opened mine up to even see if the placement of this is even possible.

     

     

    this.

     

     

    you could definitely mount a pot there, but I'm not 100% sure what the best way to go about is. I would probably remove the existing pot from the PCB and extend wires to from the PCB to the new pot.

    I have a junk DJM800 that I managed to find a compatible pot in. It was a different value but that doesn't (generally) matter for gain/volume controls.

     

    Thanks for the offer! But more interestingly, you think that I could use a different value pot for both? Because if that's the case I think I could definitely find replacements.

     

    edit:

     

    I found a ALPS rotary in the same dimensions but in 10k.

     

    edit:

     

    nvm cant find any slide potentiometer in those dimensions that are dual gang

    Have you looked at the pots to see if you can salvage them? I think Rane parts are going to be really hard to find going forward. Have you tried mouser?

     

    I'm going to test the rotary pot to see if it still works. I did manage to "reassemble" it but I'm not sure if its put together right. The slide potentiometer is toast. Yea mouser is the first place I looked. I also checked digikey and they don't have much in stock either.

     

    This is the closest thing I can find for the rotary pot

    As for the slide potentiometer, I haven't found anything that is suitable. -_- At this point I might just make the dry-wet a rotary as well.

    Found a Rane TTM-56 for $280 but with multiple broken pots. I have no problem replacing the pots. Everything else is in good condition. My issue is finding the original ALPS components. I've been on ebay all day and none of my goto electronic sites carry any ALPS with in the specs. I've found some comparable components from other manufactures but even those have some ridiculous lead time. I've contacted rane via email but no response yet. I found this site instrumentalparts.com but everything is extremely over priced and non-oem. Anyone got any sources? Thanks!

     

    These are the specs that I can gather from my observations and measurements. If anything is wrong please let me know. I'm guessing on the tapers.

     

    volume pot

    • 20k ohm
    • dual gang
    • top adjust
    • pcb mount
    • D shaft
    • 6mm ⌀ shaft
    • 15mm length shaft (including threads)
    • 7mm length flat area
    • logarithmic taper (?)

    slide pot

    • 20k ohm
    • dual gang
    • pcb mount
    • 20mm travel
    • 20mm lever length
    • 1.2mm lever thickness
    • no detent
    • 9mm width
    • 35mm lenght
    • 7mm height
    • linear taper (?)

    Nice! When your ultrapitch is in effect does the platter speed fluctuate at all when cutting? I noticed that the ultra pitch kit from open-format does that a lot and the workaround they have suggested was sanding the edges of the platter Rim down so it is flat and smooth and that little Ridge won't provide friction. Even doing this it's still fluctuates a little bit when the pressure is applied and it is very annoying. I was wondering if your version those the same?

     

    I tested a similar generic PWM speed controller and I had inconsistency at low speeds as well. I'm thinking that the frequency is just unstable. I didn't do extensive testing but I'm thinking there is a combination of voltage to "speed setting" that could yield better results then just dumping the pitch to its lowest speed (lowest voltage). With my mod there isn't any fluttering since its just reducing its voltage. Its very smooth at 1k ohm. I don't know exactly what RPM its running at but it is noticeably slower.

     

    Holy shit dude that's awesome! If you can get those finalised by the time the mini inno plus comes out you'll make a fucking killing

     

    Thanks, I'm taking precautions in the design to try and accommodate for any big changes to the mini innofader plus since I only have the mini to reference. My only concern is the additional connector on the left. Hopefully its actually a 5pin jst xh connector and not a surprise on release.

     

     

    Nice work!

     

    Thanks

    Also did a selectable ultra pitch, toggling between the original trimmer pot for 33.3 and a 1k trimmer pot.
