Re: Design software for Mac?
Hello again, Gavin, the "online only" statement isn't completely true. I've been offline for months at a time, here are times I need to reconnect and "Sync up" but most of my projects are private, that is an option. Working Offline is selectable, follow the tutorials to start. There are i think 12 modules in the series, you can contact me PM if you'd like. Best of luck to all, and May we all stay safe and healthy. |

Thanks for that. Be aware, though, that the free edition is online-only. |

Re: Design software for Mac?
Hello All, ?I've been using EasyEDA for about 1 year and its very intuitive in its behavour, My only issue is it defaults its parts selection to it's parent company. That said there are tutorials on their channel on youtube, BTX its free and supports win, MAC, and LINUX. Check it out at: ? |

Re: Design software for Mac?
FYI I learned about the SnapEDA library and the Digikey library for Kicad last year and it cleans up alot of that troublesome transitional period you're talking about (switching platforms). It would be worth a peek to get those libraries and Kicad and try them out together.?

Re: Design software for Mac?
Thanks for the suggestions.??The DesignWorks schematic / simulation software?I have been using?is no longer supported on Macs. The Douglas CAD/CAM system is still around, but upgrading to the current full version is $400. The advantage is my libraries could be carried over. The disadvantage is price for an occasional simple hobby project.?I am not laying out 6-layer impedance controlled motherboards these days.
I'll check out KiCad and Eagle, but the more I think about wrangling new libraries into shape and learning a new UI, the more attractive keeping the old Cube on a desk looks. :-) |

I use to hate KiCad. I have used what is now known as Altium, but my latest version dates from 1999!! I tried KiCad many times, because I can not justify 10K$ + expense of what is now a hobby for me and really did not like it! Since the CERN :??took over the design of the software, this thing has become a beast! I strongly recommend it! The first step are not as steep as they used to be, and there is a ton of you tubes to learn it. And by the way, if you are also in 3D printing and mechanical design, check FreeCad!? A designer friend of mine found it almost as potent as Catia and SolidWorks! (He uses both!) Luc |

Re: Design software for Mac?
¿ªÔÆÌåÓýI had been using pcb-rnd on linux, but got tired of having to remember lots of linuxy stuff to maintain it. I recently started using librePCB on mac, it is likely more limited than kicad, but I had taken a dislike to kicad for some reason I don't now recall.
I am building up a library of my own thru-hole components for mics using librePCB I think librePCB has decent potential but it is still new. The
overall paradigm feels closer to a mac program than other pcb
layout software I have tried.

Re: Design software for Mac?
I can't say enough kind things about Kicad 6. It's seriously competitive and I say this as a user and owner of Diptrace with a pro license.? If only there was a more universal format for collaboration between platforms.?
Footprint creation and symbol editing are actually pretty straight forward though you still need your calculator from time to time for PCB layouts.? -L. |

Re: Design software for Mac?
As Matt I use Eagle CAD, but in my case the 7.6 free version. It's limited, but works fine for what I do.?
?
Version 7.6 IIRC, was the last version before the company was acquired?by Autodesk, so no cloud online accounts or registration is required.?
?
I use the Windows version, but there are also versions for Mac and Linux.
?
Here is the download link:

Kind regards!

Re: Design software for Mac?
Eagle CAD still has a free tier. It¡¯s limited to 2 signal layers and 12 square inches of PCB area ¡ª both of which are sufficient for most mic circuit designs, in my experience.
The interface is famously inscrutable, but there are many online resources to help decipher the tools.? Its 3D integration is not great, but likely to improve now that Autodesk has both Eagle and Fusion 360. I¡¯ve seen other CAD apps that output a 3D rendered visualization of the PCB layout. Eagle doesn¡¯t seem to be there yet, or at least, none of the component libraries I use have any 3D models attached. Perhaps that¡¯s still to come. ¡ª matt. |

Using Jerry's idea in post #3 of using 3 op-amps, I've added a 'multi pattern' version to my collection of OPIC project mics here:
Seems to perform really quite well for such a simple variation..... |

Re: How to test if dual condenser capsule is working?
All good. As I said before no issue with the voltage (constant 64v occasionally -50mv). Mainly housing issue. I mean very tight space for all components and interconnections. I reflowed some solder around the 1gohm and the Opa legs and all good. I put things back while I was auditioning? it loudly through headphones (I know it can be dangerous for a lot of reasons - but I 've done it before with other builds). The issue was mainly the interconnection cable of bias that was touching somewhere, and something around the xlr base (I guess all the trial - error with heat on the cheapo components of BM 800 mic body don't help a lot). Covered the exposed things, put things back carefully while listening. No external noise. Really really quiet built. Good signal to noise ratio for my liking. A bit darker sounding mic, compared to my usual ADK Vienna and also compared to the OPA based electret build.
I think it will be an ongoing project, since I have some more boards and there is another capsule side that asks to be used (and a personal ambition for a 3 mode DIY mic). But I guess I will allow myself some time with the cardioid part just to familiarize myself with the characteristics and the potential issues that may arise on these 2 newly built mics. Thanks Jules for the excellent design and Jerry Lee for the advice and help while things were not clear. |

Re: How to test if dual condenser capsule is working?
I assume that you are constantly measuring it? Hi Jules. I mean I was measuring the supply on its own for quite a long time several times before using it on the mic. Because it was built last (after an accident on the previous one). I will follow your guidelines carefully (most of my voltage are correct - haven't? measured around the 1gohm yet), And the SMDs can be a little bit frastruting on what is considered a good or bad solder without microscopic inspection....It's good to know that such problems have sn easy(???) fix. ? |

Re: How to test if dual condenser capsule is working?
Please look at this. You have something?touching possibly. I write this based on my own feedback (I have misconnected almost anything that can be hahaha) And from users I have helped to get this going. When you say the sound squeaks and then starts to come and go AND that you have a constant 65V I assume that you are constantly measuring it? The symptoms you describe sound like the voltage supply at the OPA dropping and then returning. Typically that is when something?touches intermittently. Jules?

I insulated both pcbs (bias- high impedance) using tape around them and I cover all the inside of the mic body with copper tape. Good signal and healthy signal? initially with phantom. No noise.??All my testing setup is good with any other mic.? --
