Nice -looks like a cool setup. I've gone pretty much all guitar but I still have an SY77 sitting 2feet from me. Needs a backlight update.

I'm guessing the Eurorack stuff is pretty picky - probably not high current? I've done linear supplier forever but a) they're big b) have to be sized carefully for the application or you waste a ton of power into heat, etc. Sort of why I've been experimenting with SMPS. A lot of garbage out...

how do you like your DC7? Expensive -but worth it? ... I have a lot of 200 series Boss pedals a GT1000core and hate all the separate power power supplies.

Which Cioks do you have? DC7? Would REALLY REALLY be interested in what that looks like. Thinking about getting one.

Exactly - and don't forget that whatever (transformer, etc) is feeding the 14V has to be able to deliver the power. The transformer has to be rated for the power you will be using, and may be as high as 20v when not working hard. Which will then drop to xxx volts the harder it has to work to...

Don't have one. Have an old Vitoos DC8 supposed clone. Powered by a 12V 2A SMPS (with spikes) that it feeds two 1000mA (isolated from each other) which both use a LM2956 to get the 9V. Then there are 5x300mA non isolated (regulated). The 1000mA ports are "clean" the 300mA pass the noise...

That's what a lot of the app notes imply. You can do LC but then you potentially have a tuned oscillator dependent on loads. But like my last post shows - they can be made pretty smooth. Or not. Depends on what was asked for by the PS designer I guess. Linear are much more straight forward...

Seems like there are "good" supplies - I imagine a lot of the pedal board power supplies as switching. This is a DVE power supply 12V into an LM2596 to get 9V - actually better than the $40 BOSS supply. *typo on the first plot should be DVE and 9V regulation (actually set to 9.3)

Wont work on these high freq spikes (I tried). There are articles that discuss SMPS but its not easy. I dont know what BOSS and DVE are doing but they're a lot better. The spikes get past a linear regulator too if I put a LM7809 after a 12V SMPS with spikes. If you use a RC *filter* that might...

They're with a resistive load. Doesn't change the spikes any. I have a test switch box to go from 0 to 100mA, 200mA etc resistive load. Changing load affects the volts (more / less depending on the supply) but the switch pulse stays pretty much the same.

Would really be interested to see what the "1 SPOT" (original) looks like. It looks like the generic SMPS but I know they can be made very quiet. I have a random "DVE" 12V power supply that I think is for a network switch and it's as flat and smooth as the boss. Most look like the TRIO type...

So I've been messing around measuring the effects of load on various 9V power supplies I have. Most are switching mode power supplies but I've looked at the old school transformer ones too. Looking at the voltage with a scope is interesting to see the switching artifacts. The BEST by far is...

Thanks - yeah its a lot different with the momentary vs the latching "thunk thunk" kind. And yeah the short shaft is what I really like and not sure if LMS has them as short.

Anyone use the tayda momentary footswitches? They also carry the Daier version - but Daier (sometimes) has the smaller actuator 8.5mm dia vs this 10mm. Quality? Smoothness? I see Love My Switches has some that look pretty similar. Anyone use the Tayda switches? Interesting they say it has...

Thanks for the info. Yeah the NC doesn't really seem generally available. I've seen the bias approach, or if the geometry works just move the magnet "away" during actuation to get the opening.

Where did you get your reed switches (brand, etc)? I was going to order some cheap ones off amazon but the reviews are sketchy in terms of failure rate/quality. Are those "Coto" reeds? Coto makes great relays.

yeah the 'self contained' is what makes it attractive with the clips. Only challenge is attaching a magnet to the plunger. The xwing plungers at the tip are only 2mm dia vs the 4mm on the "actuator". But I see they do make 2mm dia magnets, and I could "stick" that to a 4mm , etc lol. Or...

thanks missed it :) good image from mouser on the alpha part that they sadly dont stock

I may have to experiment a bit. I have a bunch of Roland(BOSS) switches that are used with tactile 12x12mm switches that could probably be used with the reed switches. And the "XWING" style (broken ones I have) come apart and might be able to be turned into an actuator.

thanks! shows up in US - too bad there isn't dimension specs. The Daier footswitches are usually 8.8mm dia on the plunger vs "normal" of 10mm but not a big difference
