Re: Eben Upton on BBC Radio 4 "The Life Scientific"

The RPF finances are, if I'm not mistaken, a public record in the UK, probably through annual tax reporting. That's correct, but it's basically (rounded) £17 million in, £10 million spent, total funds at the end of 2016; £14 million. There's details on how the business costs are arrived at but litt...

Re: Cannot install Cython

I recall that when I installed Cython I simply used apt-get rather than pip -

sudo apt-get install cython

I vaguely recall having tried pip but that was taking forever so I aborted that and used apt-get which took mere seconds to complete.

Re: How to add concatenation

Or you could just have done ...

Code: Select all

n = s.find('JOIN')
s = s[:n] + '/' + s[n:]

Re: Pi Zero as DisplayLink Adapter

It's almost certainly possible but would require drivers for the Pi and for windows to be written, and, at least for the windows end to be properly signed. A non-trivial task I suspect. Signed DisplayLink drivers already exist for Windows, also for Mac, Linux, Android, Chrome OS and Pi. So as long ...

Pi Zero as DisplayLink Adapter

Does anyone know if there is any software which can be used to turn a Zero/W/WH and its attached TV/Monitor into a DisplayLink adapter ?

I have a serial adapter I can connect to one of the RPI3 USB ports, but the system won't recognize the cable at all.
I am almost positive this is an issue with drivers.
Possibly. What cable is it, who is the manufacturer, what's its model, what does 'lsusb' show when it's plugged in ?

Re: When will Raspberry Foundation admit that the Pi destroys your SD cards?

Long up-time may be what avoids corrupting the cards. Long up-time doesn't indicate anything about other use cases.

Just pointing out the logical fallacy rather than apportioning blame.

Pi's can indeed have long up-times, claims to the contrary are not correct.

Re: What can be realistically programmed in assembler today?

Assembler is useful if one wants to run bare metal in the GPU, wants to use the SoC as a super-duper micro without even enabling the ARM cores.

Not that many people would want to but it's fun none the less.

You can buy kits with the headers included, but not soldered on. There is more than just the header in the kit though, and you still can't buy more than one. Not that I've seen.

I'm hoping the ZeroWH will eventually be available in bulk since it's higher cost enables distributors to actually make some money on them.

Pimoroni are charging you £3.80 for someone to stick the header in and run it through a solder bath.
Are they run through a solder bath or are they hand soldered ? I would have expected them to be hand soldered.

A+ are currently £20 @PiHut. Given the ZeroW is less even at £15, that should be a start point with a max of £20. That's roughly my feeling too. There's an argument that people wouldn't pay £20 or more when they can get an A+ for that and it has some validity. But the Zero W is a different beast; s...

Re: pi zero w in quantities of 10...50

Based on customers currently able to buy 10 Pi Zero W's, one per order, for £121, a bulk purchase of 10 Zero W's at £130 did not seem unreasonable. That represents an effective £12.70 per item compared to the single £9.60 cost. I believe people would pay £15 per Zero W for single or bulk quantities....
