Yes, I’m still in business. But very quiet, since I haven’t released any new designs for quite a while as the rest of my life (including my day job) have been rather busy. But supporting existing customers of my designs remains a priority.
I think you might have emailed me about this a day or two ago - if that was you then I’ve just responded to your email (sorry for the delay). Please let me know if you’d like me to share your question and my answer here.
I just checked at it seems I never did a manual for the 1SW! It’s a simple, passive module but there is one customisation option that you’ll need to know about when building it, and there’s a knack to putting it together easily that I need to write up. Sorry about that - I’ll get on it.
