hi.. can you explain the different mini kit options in the spreadsheet so I can order the right ones?

Here is the blog about it.

Use the calculator in the first post to order the pot and setting resistor etc.
Hey Tea-Bag - when do you expect boards to be available again? I'm torn between using BIB or the Sigma 22/11 combo for powering my next BIII build. Sigma11 is overkill for the 5V digital supply, and thermally it's gonna throw off alot of heat.
What if any advantages does BIB have over the Sigmas? Thanks in advance for any thoughts anyone can share on this subject.

Hmm ... I would think though that the BiBs would throw off a lot more heat. From what I remember, the Sigmas are series regs, not shunts like the BiBs.
You'll get more in the way of regulation I think with the BiB, as well as a smaller footprint tho.

Could you please explain it to me in more easier words sir? I have very little experience in electronics and dont know if its worth and I would have to buy BIG heatsink for proper work? What temperature should I expect from such PS without box? Im searching best solution and so far tried only 12V, 7,4 Ah accumulator through simple regulator but its annoying checking it day after day
Just received my kits, thanks a lot TeaBag.

Get a 9V 1A transformer, get one 5C/W side sink common to the reg's 2 power semis & TO-220 silicone pads. Set it at 700mA, and expect ~25C above ambient temperature on the sink. More in the builds thread if you will decide to start with it, read the pdf guide in post #1 here first.
5C/W sink example.
Thank you Salas.
AndrewT its no problem, I have friends who could help me but already away or offline I want to try that PS badly! If not with XMOS I could use it with other equipment
One more question - I assume Ill have to wait some time till next GB runs with sending kits. Can I buy for tests such regulator from Chinese seller and use it or its only similiar but much worse?:
