Raspberry Pi3v - what size capacitor?

Hello, I am using the raspberry pi3 on an Atrix lapdock and want to use a capacitor to make sure the pie will stay powered up when power is removed for 3 seconds (accidental lid close). A 1000uf capacitor was needed to boot without the lightning bolt coming up on the screen. This tells me that there...

Correct buffered line driver IC?

I have one of the DIY Gertboards and have just assembled it the other day. There were no line driver ICs (MC74HC244AN) in the package. I went to my local electronics store (Jaycar) and they gave me a substitution of SN74HC244N as it was the closest thing that they kept in stock. Is this a suitable s...

Re: Rasberry Pi RC Car + Camera??

Thanks Daniel,
That looks like a great start! I will try and work through all the information (a lot of it is above my head but that's what this project is all about "learning to use the pi and Linux")

Tanks again :-)

Re: RS & Allied Update #3 (27 Sep)

Everyone here is upset and rightly so. - It seems to me that RS has not taken responsibility for their inability to make deliveries. Instead they artfully palm responsibility off to the “high level of demand on the core Raspberry Pi processor chip”. This excuse has been exposed by their competitors ...

Re: Cheap powered USB hub?

I had one of these from e-bay that was very cheep. I stoped using it after I noticed that when I used it and unpluged the Pi that the Pi was still powered and did all kinds of crazy stuff. I would agree avoid like the plague!!!!!

P.S. You could tell that my unit was manufactured very poorly.
