Re: Use a 2-gang USB port to power a Pi ?

The other thing to check is that the USB cable is short and thick. [...] For carrying up to 2.5A, which is the normal maximum for a Pi, you want cores of at least 22AWG, preferably 18AWG (lower numbers are thicker). Interesting ... I wasn't aware of this specific - thanks, David :) As I have severa...

Use a 2-gang USB port to power a Pi ?

Hi all, Have had a search on the fora & not found anything useful on this topic, so thought I'd try asking direct - just in case my Google-fu is failing me :o I've recently been doing occastional 2-gang replacements around the house to have USB ports available in various rooms; this is the one I've ...

Re: Slim power supply

Does anyone have any recommendations for a slim PSU that puts out enough power for a Pi3B+? [...] Are there any good slim power bricks that put out enough power? Why not just replace your wall socket then ? This one https://www.amazon.co.uk/BG-Electrical-Masterplug-Double-Socket-822u3/dp/B01MQE5VJ1...

Re: New Raspberry Pi model 3B+ 1.4 GHz, 330Mbit Ethernet, 802.11ac, PoE

I would look on a pre-loaded card as a convenient, but not necessarily inexpensive, way to get an extra SD card and immediately re-flash it with a current image. Unfortunately all those 'pre-loaded' things are old and insanely slow SD cards being often 100 times slower than any recent and good A1 r...

Re: Direct telescope control of Meade RA & Dec drives

Roy, From a quick scan of the manual, all the clever bits are in the handset - none are in the two motor boxes. In my opinion, you're wasting your time trying to recreate the controls using a Pi.

Re: Not sure which camera I need for my project

My first thought would be "do I want to tip 'them' off they've been detected ?" ... If yes, them just get the ordinary camera; if no, get the NoIR camera & use an IR light to illuminate. A light sensor would be sensible, unless you don't care if you fire up the IR light during the day ?

Just for closure ... I had a little hunt for these cables once Dougie had pointed this one out to me; saw a splitter with Pimoroni (who I normally use for Pi-related stuff) but wasn't too happy with the longer cable lengths & having a pair of Micro USBs dangling around. So went for the PiHut version...

USB power between Pi and screen

I recall a while back that there was a promise by one of the popular 3rd-party companies to make a short USB cable so you don't have to power via the GPIO. Did this ever come to fruition ? If not, does anyone have a (UK) link to a suitable cable ?

Cheers,

Re: Telescope Adaptor - Any 3D printable designs?

Simple answer is to use an old film canister Well ... the DIY answer, anyway. The properly simple answer (non-DIY) is to buy the M12 adapter with 21mm spacing, screw that onto the camera (after removing the lens), then screw in an M12 webcam adapter onto it. You'll likely need to do some minor cutt...

Cheers Mark,

I recall seeing the first one a while back; no-one else made any though ? I guess it's functional, albeit basic & lacking in aesthetics ! :lol:

I don't consider the second to be viable though (well, not for my needs) given the ring of LEDs all around it ! ;)

Anyone made a Petit Studios camera case ?

As some may know, Petit Studios has a board that allows the RasPi camera to be extended via HDMI cabling. I'd like to enclose the two boards into a case rather than handle them as bare units, but am drawing a blank.

Has anyone done this ?
