Are we able to use this design as I would like to build a Klee in MU

Eventually

Or is this Megaaohm design strictly his personal signature.

Sure is nicer than the MOTM version.

I would love to have this layout if it allowed.

Very nice indeed

Yes the oshpark needs a bipolar supply so when you flip the switch it goes to the negative voltage. If nothing else put some batteries in series or parallel, can never remember which is which, just look it up so you get a + and a minus. I have a dc power supply and Im just gonna make a MOTM cable to...

No you should be ok The original Ian Fritz post says its 10v but anything around there should be ok. To be honest I've not built mine yet. Just look at the start of the thread and you will get the info you seek. I cant remeber off hand the details but its all there in the early part of this thread. ...

@ Broadwave, When I was refering to the front panel not being the same I thought there were two black switches on the bottom left but I guess I am mistaken. What functions do those extra pcbs you have in the shot of the base of your synth. So you made that aluminium box by bending it with a workmate...

Ok great thanks for clarifying that for me, I thought perhaps Broadwave had modified the pcb or something. Oh that reminds me. Hey Broadwave how did you fabricate the metal box part of the synthesizer. Julien, new project, oooooooooh, Any sneakers as to what it might be or is it far too early days f...

Hey Broadwave that Synth is looking sweet and I prefered either the linseed oil but liked most the teak oil if that was the farthest right in the pic, it seemed to bring out the grain somewhat. Ben at resynthesis the panel guy has some rocker switches now and are you going to get a left controller c...

I think a square is better for the clear on off component rather than the gradual sine wave. Bloody hell why are some things not striaght forward I just want to match some caps to within 1% Trouble is I'm really really bad at maths and I dont know how to ascertain what 1% of 1.5 is Basically Yusynth...

what is this then, it looks like a wheaystone bridge and on youtube it describes exactly this and I an Fritz' circuit is a wheatstone bridge which he says himself in his article describing his circuit. Look at this video, if you dont want to watch it all jump to 2.56 where it describes a wheatstone ...

Can anyone tell me if the Ian fritz circuit can be used to measure capacitors as when i look up how to measure a capacitor (for matching purposes) a few articles refer to the use of a wheatstone bridge (which is what Ian Fritz' circuit is, as said by the man himself) which is fed a square or sine wa...

Yeah I know but they are out of stock I checked after your first post on the subject Yes I thought as long as it is Moog scale they would communicate and yes thats what I mean, I ramble on a lot and its probably very easy to lose the gist. That CP-251 looks a nice piece of kit. Sweetwater was demons...

I've been meaning to ask this for a bit now but just remembered. Will the BF245C be ok, On the BOM it just states the BF245 but obviously there are three iterations, A,B, and C, C being the lower of the specs. Ledman has BF245B on his site nut they are not necessarily for this project. I would of th...

Hi jdelgoulet, According to the data sheet it says its +5v 5a, +12v 2.8a and -12v 0.5a Thats why I was asking about equal power to each rail as the minus is rated at 500ma but it will go up to 1a from what I can gather. Threason I asked if it was you on Yves site is the name is Guigui and from fance...

I am new myself and dont knoe how to use it either but from what I can gather from Ian fritzs circuit is you put at least 10v . ino the circuit add two transistors into either the right side which are pnps and left npns and measure the voltage one way for eg the + volt and then flip the switch to - ...

@ Broadwave I'm so glad you put me onto that Timber yard, it turns out its only up the road from me, well 10 miles but hey its a big road. What a brilliant place, I was looking for for timber yards a few months ago and never found that site, strange. Anyway I cant wait to see you Synthesizer when it...

Just thought I'd put it out there that I got 3 of the Ian Fritz pcbs modified by Fonitronik and X and Or. The circuit is the same as Fonitroniks you can see earlier in this thread and has been modified by adding a MOTM header aswell as the 10 pin Eurorack header. They were only about either $13 or £...

what is the average power consumption of Eurorack modules so I can make a rough guesstimate as to how many modules the RT-65B will power. Obviously the Mini Module will take up 60hp and that will leave 44hp out of a 104hp case. If anyone would have an idea (ballpark) of how many modules the RT-65B w...

@nickster What power supply have you made Thats one of the dilemas (there are many) I'm having as to leave it stand alone but there needs to be some form of interfacing with the unit and as you say there are also effect and utility consideration also. Its not so bad if you have a eororack with other...

Those diy pcbs for the pots and switches do they do anything specific or are they just an aid to enable interfacing/wiring them to the analogue board.

Great advice, as you have probably read as and as my mum says I live too much in my head and think too much instead of doing. Thats what I thought with the Ian Fritz pcbs, Oshpark is a great service, it cost me £13 for three pcbs posted to my door, now thats a good deal. Like you say it would cost h...
