Safe DIY options needing a 12V AC/AC adapter sound appealing, were it not for the complete impossibility to source such a wall wart at a reasonable price. I swear I looked, everything is AC/DC misrepresented as AC/AC, or costs like €30 shipped for 500mA, used, from a noname brand. Meanwhile a new RT-65B costs €25, pushes a lot more current, is from a reputed brand, can be acquired without spending hours looking through bad results, can be made physically inaccessible, and requires a simpler circuit to use. Sure, sellers are legally required to say it’s impossible to install without years of training, but clearly lots of hobbyists managed to install one safely… and the elusiveness of a proper AC/AC 12V 1A power brick at a reasonable price makes me want to just join their ranks, frankly. ---

What?!? Seriously? That is pretty incredible that you have access to those considering how highly sought after most of those chips are. If it’s possible to get this sequencer finished before next summer it would be great and I would happily wait and of course pay for whatever. I’ll message you with what I am looking for to see if you can help. If not, that’s okay too. I appreciate you trying! ---

> [@analogoutput](#): > > Only 500 mA on the -12V rail though. Is it a limiting factor in a typical Kosmo build? Seems a lot of commercial eurorack PSU also are 2A for +12V and 500mA for -12V (plus the 5V rail Kosmo doesn’t use). ---

my [SSCSS](https://lookmumnocomputer.discourse.group/t/2370-spring-spring-crunchy-spring-spring/5447) arrived today. just one day after @twinturbo who if i’m not mistaken lives considerably closer to the source… NICE! ![20220917_123216](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/3/1/310f55aa7c5c8ee0b1856fd42b583aaf1b1574b8.jpeg) ---

For those of my modules whose current draw I’ve measured I get 385 mA +12 V, 296 mA -12 V. (Somebody, @CTorp ?, posted current requirements for LMNC Kosmo modules a while ago, don’t know the link, my recollection is it similarly had +12 V higher than -12 V but by only a smallish factor. And I think you see the same-ish for most Eurorack modules on [modulargrid.net](http://modulargrid.net).) If you scale that up to 500 mA on -12 V, it’s just 650 mA on +12 V, leaving most of the RT-65B capacity unused. Depends on the modules of course, if you have a lot of microcontroller stuff it’ll skew things toward +12 V. ---

My contribution to today’s Mail Day consists of a misspelled e-mail telling me that my August 8 Aliexpress order has been delivered in my mail box, which is actually empty. Their web site ( [http://groupetsm.fr/](http://groupetsm.fr/) ) looks like amateur hour, demands my full address to contact them despite looking like a phishing site, while their phone will not answer. Fun! But while I’m at it I’ll also take the opportunity to show off I did a bunch of inventory management today. What a pain it was to get sufficiently stocked up to get started! But by now I have most of the stuff I need to furnish an entire army of EDM producers. Lots of cross-referencing with what is used in real synths stuff, so very few components I bought but realized I would never possibly need. ![inv](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/3/f/3fbf750a64cd3c5398a43252f601cb1f5a9a1a6f.jpeg) ---

For clarity. Electrocution only happens once, and electric shock can happen multiple times. If you don’t takr the warnings from the latter, the former may occur and you can’t revisit your mistake. My PSU design is 240V feed , and it’s in my main synth case. but it’s in a proper enclosure. It has the mains plug fuse, it has the fuse before the transformer, and it has a fuse on + and - outputs from the rectifier. @Willi359 yeah, mine only had to travel a few hundred miles. I would say I am waiting on the BOM and video from the new workshop @lookmumnocomputer … But in reality I have the QuadLFO to build first … ---

> [@twinturbo](#): > > we have community De-Fibralaters all over the place so if you do get Zapped then someone may come allong and **jump you back to life** by zapping you once more. So is it that being zapped an odd number of times is bad but an even numer of times is not? ---
