SDIO WiFi
What's SDIO WiFi?
WiFi module connected to the Pi's SDIO interface exposed on GPIO header.

Recipe: 1 x ESP-12E or F module @ £2 off ebay, solder 6 wires, build kernel module, add line to config.txt -> 40Mbps WiFi, with the single USB port left free to host arm mbed board (or whatever else). £6 BOM inc Zero.

Adafruit had some in this morning.

They went from "In stock" to "45 in stock" to "Sold Out" in about 30 minutes.

The Zero must be the Cabbage Patch doll of SBCs.

Love the idea - is there a thread/instructable on the subject so we don't derail the complaints on this one :)

The full version of my tl:dr summary above is here: https://hackaday.io/project/8678/instructions

The 33 Ohm resistors aren't needed (tested here OK & I note the Zero itself skips these series-termination resistors on its uSD slot).

If you prefer a (slightly) less hackish approach than flying bodge wires then I have a few spare builds of my own twist on this: https://hackaday.io/project/10097-shabp ... or-pi-zero

And Niven was the first place I read TANSTAFL.

Not shure who said it first Hinelen is credited with poularizing it.

TANJ. ;)

Nope = PiHut lasted 1 hours before selling out yesterday - Pimoroni just lasted a bit longer this time as no-one was expecting any and had give up checking the website!

Fair enough, but modern popularity traces to Heinlein, and definitely NOT Niven. If it had been in a Niven work, it would probably be a Niven-Pounelle collaboration and would have been put there by Pournelle at a guess, as it's rather more a Pournelle sort of line than Niven.

What book? TMiaHM was published in 1966. Niven didn't even start getting published until 1964, so he almost certainly got it from Heinlein.

I was just saying I read Niven before I read Heinilen, Sheeesh!

Plus Niven may have got it from popular culture you could go ask Larry Niven he is still around. To go ask Heinilen could be an issue he died 1988 so I gues we cannot realy ask him unless Ouija Board anyone?

Its a pointless argument I am begining to wish I hadn't bothered with the citation, but thats a spin-off from a University Education for you you have to cite someone or its plagiarism. 8-)

Okay... Niven may have used it. I don't recall seeing the phrase in any of Niven's works. That's why I wanted a citation. I haven't read all that much Niven. I have, however, met him on a number of occasions (I only met Heinlein once, at Mid-Americon, the 1976 worldcon in St. Louis, where he was GoH). The last time I saw Niven was at a memorial for Poul Anderson.

Can't be bothered to split this in to Off topic, so either start a new thread of stop posting. Everyone knows that Number of the Beast was the worst book ever by anyone, so that brings this discussion to an end.
