Re: Eurorack Scopes

It's not modular but when I wanted a scope for my rack I went super cheap and got a DSO 138 for around $20-$30. I had to do some soldering but only through-hole since I got a kit with the SMD pre-soldered (maybe all the kits are like that?). It was very easy to build. You can get them from places li...

Re: Synthcube

I want to like SynthCube, I really do. My last order was re-routed back to them (coast to coast) because they did not have my complete address on the shipping label. The package got within a mile of me, but was sent back east. I'm really not sure how this happened because it was through PayPal....a...

Re: Adapting the EuroRack audio world for video synthesis

Depending on the monitor and the audio signal, the monitor might not like the signal voltage and it might break something. Line-level audio probably won't be too risky since I think that's usually closer to video-level voltages, but modular-level audio is usually 5-10 times higher voltage than typic...

Re: Adapting the EuroRack audio world for video synthesis

Thank you very much for your reply FetidEye, I understood that sync was useful but I thought without sync no video at all would be produced and I was wondering what the technical reason was! Now I understand better, that the output will not be a simple black screen, but perhaps "unstable" It also d...

Re: Mutable Instruments Veils 2020

VCAs are very much set and forget in my case, so I don't really care and I prefer the expanded control of v2. Would be nice if Mutable discounted old revisions to give buyers a heads up. I believe Mutable usually waits until stock is pretty low or completely out (at resellers) until announcing a re...

Re: Instruo Lion Matrix Mixer

Nice module, and one of the better implemetations of amatrix mixer. But how can they charge $325 (according to modulargrid) for something that basically is 48 jack inputs? 48 jacks at thonk would cost me £20. Ok, I know there's more going on inside the module, but jesus the price of eurorack is sic...

Re: Ultrasounds?

Yeah, the frequency doubler can get you some more vertical bars. The Cadet Ramp generator has a doubled ramp output already, which is like one vertical bar. If...

Re: Ultrasounds?

You could look into LZX's oscillator modules. They're specifically designed to go into video frequency ranges, which start at high audio frequencies and go up from there. The audio modules that I've tried to get up to video rates either couldn't make it as far or were far less stable at those freque...

Re: Ideas for small hard-to-accidentally-hit reset button?

Also see that a version of my second suggestion is already here. That being you may not want to run the full DC power of an Arduino through a typical tact switch. The current isn't trivial, and DC ratings for switches are FAR,FAR less than for AC. Meaning you're setting yourself up for fused switch...

Wow. Lots of great ideas! Thanks everyone. I'm going to have to think about things and try to figure out what works best.

Ideas for small hard-to-accidentally-hit reset button?

I'm designing a eurorack module that's powered by an Arduino and is being designed so that users can make their own code for it. (I know, I know... these already exist. But I'm making one for video synth purposes, so some of the electronics necessarily needs to be different than existing ones.) Whil...

Re: Audio from video?

One thing I've thought about doing but never actually tried yet is putting some LDR's (photoresistors) on a video monitor, spaced out, maybe in a grid. Then set up a voltage divider per LDR, using the LDR as one of the resistors, and doing something with the resulting voltages. That way different ar...

I also found self adhesive boxes that peel and stick for the outer box. you pay about $0.30 extra to have a time saving feature like that.

I'd be interested in a group buy, for somewhere between 30-60 pcs (maybe more?), depending on price. Not sure if that's a smaller qty than you'd want to do for minimum group buy or not, if it happens.
