macMini (HDMI/USB) to diy DAC (RCA S/PDIF) what's my options?

[myleftear]

Hi friends!
So after a long journey playing around with analog, I'd like to turn my eye to this DIY Dac I got from a former DIYA-member.
Problem is, I need some conversion.
Source is a mac mini 2018, with either USB or HDMI out, and the dac only has that SPDIF RCA plug.
I've found some cenverters, M2tech for example, most are way beyond my budget.
What's my options?
Can I connect something HDMI to RCA?
Is there a simple DIY jig available? (I am not very good at electronics, and nothing in digital, although I build a few things...)

thank you!

The simplest, cheapest route to a converter would be buying one of these. Likely its based on PCM2706 which is a quick and dirty solution.

If you have a bit more to spend than $7, you could consider one of these. I'd not go the HDMI route myself, USB is a safer bet.

Thank you, @abraxalito !
This $7 jig looks adventurous 🏴‍☠️
Before spending too big, I shall give one of those a shot …

HDMI is S/PDIF with video attached. There are adaptors that tease just the S/PDIF out.

Mac mini probably has tos-link spdif output IN the headphones/line out 3.5mm femaile jack (the toslink spdif input is at the mic IN 3.5mm jack)
This is the one of the best sodif sources i tried. In the close range to shigaclone spdif...
You need toslink/sdif converter.
OR if You have some space inside the mini, You can override toslink part and took the SPDIF signal to small coaxial jack output.
That is what I did on some early model of mini. And for choosing the SPDIF just need to put into the 3,5mm plastic toslink jack (without connection)
because this will mini recognize as SPDIF out and send to insakked coaxial jack.

No toslink in the 3,5 mm output in 2018... they ditch that.
