Original Message 1/66 30-Apr-10 @ 03:04 AM - The numbskull electronic tinkerer show ! x0xb0x
[image file]
Welcome...
(no really, i always wanted to say that in a low slightly distorted voice...sigh...)
to The numbskull electronic tinkerer show
Here, I will attempt before your very eyes to put together a monophonic, computer controlled synthesizer: a clone of the Roland TB-303.
Now that everyone and his brother has gone through this build, I feel confident enough that every one and his brother has run in every conceivable problem there is, so I plunge !
Actually it's more complicated than that. i wanted to build one for a long time, but waiting list for kits were almost a decade long (ok, slight overemphasis here, but still...)
Fortunately, ada fruit industries , the people responsible for the birth of thid magnificent clone, have found a deserving heir in the body of
Willzyx who is now supplying express kit through his shop, and soon complete kits. Hurray!!! (note that as i write this , he is out of kits, but he should have some in the coming weeks.)
Now, the x0xb0x being an open source project , anyone can build one for themselve following the provided instructions on the ada fruit site: everything is given out, code, pcb design files, cnc files, everything. But unless your proficient with all this stuff, your best bet is to go with a kit so you don't have to source every component for yourself, which can be daunting, believe me.
so, here I will be documenting my build of a x0xb0x, both for your enjoyment and mine, of course.
see you on the bench : )

speaking of the bench, here is where the build will take palce.
On the pcb holder now is a Thomas Henry Mankato filter.

Damn you rurik, it's all of your fault !
Oh dear : ) what memories !
edit: for claritiy's sake, I'm the idiot named as Frostbyte, Ha ! : )
edit II: rurik is xoxos, responsible for many a synthesist wet dream. He also wrote this article on dancetech (the ancestor to 7161) taht really got me into DIY : Xoxos DIY Synth repairs
I should also add in all fairness that I was showed how to solder by Blacky of infamous Voivod, prior to anything ever as far as electronics goes...
enjoy : )
edit yet again: If you've actually read that thred, yes, i still have the JX-3P and the patch buttons are, as predicted, well dead. I'm still keeping it tho', lovely synth power for the money , ha! (wich I might very well upgrade with this kit when it comes avaiable : Organix Jx-3P midi upgrade
edit II: at some point in that thread xoxoxs suggest:: ''for the cost of a programmer i'd get some crappy mono with knobs and use the jx as is'' I did follow this limpid suggestion and got a Sequential Circuits Pro-One for peanuts considering what a 303 sold for back then (over 1000$ US, 10 years ago) I still have this baby (Pro-one) and can only tell you : ''From my cold dead hands'' : )

aamof i've been living in a tent on another continent for the last five months because i kept getting my ass kicked so badly in the u.s.still, i've got internet due to local kindness and managed to keep the essential laptop in my hands and am making my way through the windows api atm, so i can't be doing too badly. keeps me busy and guessing at least.
enjoy the studio and the gear! i bought the nord and z1 again, they got ripped again, i don't think i could stand going through losing a pro-one twice.

Ok, finished the I/O & power supply board and everything went like planned: the power supply is tweaked to perfection giving me stable 5,33 V to power the VCO and the smd USB chip has been charred to it's predicted death, so as planned, no USB. Frankly, i couldn't care less
Tonight the real fun begins as I start working on the VCO

Eh! ''some mouser bags'' ?
I could reorientate as a drug dealer and make a profit just from the savings from the bags !
glad you stopped by.
Ok, as of now, the analog section is completed and it's doing it's TB thing nicely (no slides yet tho, I'm controlling it with a doepfer MC4 midi to cv box, works lovely. I'll post a clip ans some pics tomorrow as I am tired now: the envelope and vca gave me a little bit of trouble.
tata for now
Message 16/66 08-May-10 @ 07:52 AM - RE: The numbskull electronic tinkerer show !!!
My pseudo diagnostic (read ''wishfull thinking'') is that the envelope and VCA ircuit aren't receiving the apropriate Control Voltages from the micro computer. there is a good reason for that. I haven't build the Computer Controled portion of the circuit. Instead , i'm driving it ''older school'' through cv/gate clipped on the board with test leads clipped to the pcb , fed from my Doepfer MCV4 which is running Seq-303.
So, i really hope I'm looking to deep into it : )
Otherwise, I'm at lost : (
here's a longish , boring recording of me going through the controls:

It turns out that everything was fine, but it needed the uC in place to be able to function properly. I guess it was never design to run as a stand alone synth module driven by cv gate

ok, nothing fancy, just going through the controls on a simple line.
Do you think it sounds like a 303 ? Let me know if you have one or have used one (Maarten, I'm counting on your feedback for this one)
All in all, it was a fun build, pretty easy actually as most everything is board mount which makes for minimal wiring, and frankly, a factory made , with solder mask and parts overlay pcb is pretty hard to goof up.
Please, let me know what you think.
thanks,
jf

Message 27/66 18-May-10 @ 05:07 PM - RE: The numbskull electronic tinkerer show !!!
Sounds great though- doesn't need to be a like-for-like to sound cool and get yer acid-freak on! Ew, MFOS equals drool- fuck yeah!
Started building a eurorack system myself a year ago, unfortunately I'm not handy with the soldering iron and wiring so I revert to throwing bags of cash at it and eat dry bread. Anyway, good job on the build- sounding like you're sure to have lots of fun with it.
Message 28/66 19-May-10 @ 02:24 AM - RE: The numbskull electronic tinkerer show !!!
Yeah, it doesn't have to be exact, I feel it's already a LOT closer than my MAM MB-33 mkII (which actually sounds more like a SH trying to sound like a TB )
The x0x has some of those nasally, phoneme like sounds I was looking for, it really talks imo.
The MFOS Ultimate is just plain sick, a real monster in this small package, here is what mine will look like

Message 31/66 19-May-10 @ 02:41 AM - RE: The numbskull electronic tinkerer show !!!
It is a complete and self-contained piece of shit that will turn any build into a slow and painful descent into the pits of electronic diy hell.
get something like this instead:
I paid 55$ on ebay, never regreted it, also ditch the moist sponge and go with the brass shavings pot scrubber type of thing instead, much better.
Then crank the iron, you want it so out that you only need to touch and go. Otherwise, keep your tip clean and tinned and your all set.
As per the wiring...
AAAARRRGGGGHHHH!!!!!
It's a bitch innit ?

Quality tracks for sure Maarten, you've really upped your game to an another level alltogether. How much are you actually giving us, encoding wise ? Will there be a possibility to acquire the whole lot as Flac somehow ?
A self enclosed package (with cd linings and everything) is not very practical I reckon, but I'd really like to have the whole wave to myself mod.

So, here is a view of the DIN board (over the power supply, with the big black caps) that I will modify with the Midi expansion kit that should be available soon, right here: around 35 EU, not bad really for what it does:
t adds a lot more MIDI functionality to the Roland JX-3P synthesizer like:
* simultaneous use of the MIDI Input and PG-200
* control the JX-3P realtime with standard MIDI CC messages. (i.e. with a MIDI-Knob controller).
* all knobs and switches on the PG-200 send out standard MIDI CC messages.
* select the MIDI channel on the JX-3P as 1, 2, 3 or OMNI
* velocity sensitivity (MIDI input only, not the keyboard)

main board cleaned and molex connectors labelled (it might seem overshoot, but I really don't want to spend anytime shagging the dog when i put it all back together, i also label screws on tape and wrap them in it)
For cleaning, I tape a toilet paper core roll to the nozzle of my vacuum cleaner, this way I'm not affraid to go in there and fuck something up. I also use natural pig hair brush to disludge the dirt. i have a micro vacuum attachment kit, but I'm not comfortable brushing esd sensible IC's with a synthetic brush, maybe i'm just over paranoid with esd, maybe not.
