I totally agree with the frequency being the most important factor with a 9+/9- CP. For preamp designs, when it comes to higher voltage split rails without whine I’ve defaulted to the big DC>DC converters in SIP packages like the TRACO, MEANWELL RECOM ones. However for just wanting some...

Oh just because I’m dealing with a build that is “whining” and this was one of the more helpful threads on charge pumps here. I noticed the 7662 was mentioned but only briefly and wanted to contribute. I hadn’t heard of this one, I’m checking it out now, thanks for the suggestion! 😎👍🏼

I ordered some TC7662B and will report back with my findings. https://www.mouser.com/datasheet/3/282/1/21469a.pdf

PERFECT! THANK YOU @Robert

Somewhere in here I saw a chart of which pins are high 3.3v and which are low GND for the 8 internal programs but I can’t seem to find it again. so if 3.3v = 1 and GND = 0 I know program #0 "Chorus-reverb" is 111 and program #7 "Reverb-2" is 000. I'm looking to find the rest.

Okay that would work. Even being able to load one at a time would be better than nothing because the customer specifically requested being able to load their personal IR that they add to all their various digital devices (kemper, etc) In fact its meant to replace a kemper in their rig with...

So it’s something i would need to code (which i have no idea how to) or possibly pay someone else to code. That’s still closer than I’ve gotten with any other option I’ve looked into yet.

So I’ve been commissioned to design a compact clean pedal platform amp (all of that is easy for me) but one of the requirements is a built IR cab loader which can run to both the amp and a DI out for front of house or recording. I’m not at all a coder (I have barely been able to flash an eprom...

Makes sense. That is what I was planning on using as a starting point personally haha

So far the only solution as a mac user for programming 24lc32a eeprom chips was buying the $13 adapter I needed to get my 2017 lenovo laptop going again :ROFLMAO: I've made random attempts for years to flash a 24lc32a eeprom chip from my mac and hit a dead end with my "oregon trail" level...

yep, down again. I'd love to use it to figure out which of the eproms i got from ppcb years ago are which haha

I'm sorry I'm resurrecting a 2 year old thread but I though I'd try some previous posts before posting a new one. I am determined to flash a blank but I have no idea how code works or what to do to get it to work on my mac.

I am lucky l have a desktop as well! I actually think I may have designed my first algorithm I’m really happy with. Now to figure out how to get it from spinCAD to an eprom without a third windows computer 🤣

Excellent suggestions and yeah, I did double check all that stuff. the only thing i can think of is a possible its a compatibility issue with M1 mac processors?

oh for sure, i just used "clean guitar loop" from the spincad designer page: https://github.com/HolyCityAudio/SpinCAD-Designer/raw/master/patches/clean%20guitar%20loop.wav-323768.wav

So i just downloaded SpinCad on my new-ish macbook (I had previously been using my imac but thought I would try it on here) When I play the sample file for the simulator (or any 32768 kHz 16 bit stereo WAV file) it plays for about two seconds, skips like a CD and then stops. Once it stops I...

I would love that info as well. I’m working on a detuned stereo reverb Thanks!

What th #&^$ are we gonna do?? Has anyone in the states found a jlcpcb-ish priced alternative with partial PCBA? (I have resistors, diodes, basic parts pre-soldered)

Haha well even though I’ve been at it for 10 years I still am pretty terrible at the business part 🤣 if I could do it over again I would have joined up with an existing company that had the business part down and let me grow and experiment but with some sort of rudder haha. Anyway, hit...

Oh seriously?? Doing it locally would be amazing! And thank you so much! I’ll check out spooky vibes now. I’ve just tried having these “faceplates” made using either FR4 PCB or aluminum and I’m pretty psyched on it. Mainly I just wanted to learn vector printing. I’m also gonna look into Lazer...
