I recently made up a couple of kits for some collaborators, which mostly consisted of the Raspberry Pi electronics. In case it’s useful to anyone, I’ve pasted the part numbers below:
|Item||Value||Supplier||Order Code||Total Value|
|USB to GigE Adaptor||£14.70||Farnell||CS25041||£58.80|
|USB-C Power Supply||£7.07||Farnell||SC15241||£28.28|
|USB A-C cable||£2.81||Farnell||CS29710||£11.24|
|USB A-microB cable (short)||£2.50||Farnell||CS22611||£10.00|
|USB A-microB cable (1m)||£1.15||Farnell||2468266||£4.60|
|Raspberry Pi Camera||£19.10||RS Components||9132664||£76.40|
That list includes options for using the Pi directly (micro-full size HDMI adapter) or for using an ethernet cable (incl. USB adapter in case your laptop no longer has an RJ45 port). It also includes both international wall-plug power supplies and USB cables to allow the use of a power bank. I’ve assumed you’re using a (micro-USB) Sangaboard v3, hence the extra USB cables and two power supplies. You can buy the Pi Camera from Farnell - they were just out of stock when I made this list.
For the components in the “bag of bits”, I used the suppliers below. If you’re in the UK, this can be obtained from OpenFlexure Industries but we’re not yet shipping internationally. Unfortunately, that includes the EU for now - don’t get us started
- Westfield Fasteners for all the screws/nuts/washers
- Simply Bearings for the Viton bands - because they are a University supplier. For OpenFlexure Industries, we prefer Eastern Seals as they give a more detailed spec and are significantly cheaper.
- AliExpress for the plastic condenser lens - see the thread on sourcing non-printed components for some links. These tend to stop working after a while so I won’t duplicate that here.
The tube lens is most easily obtained from ThorLabs, and the LED can also be had from one of RS/Farnell - only one of them stocks the exact model we use, but if you’re not too fussy about colour reproduction, any 5mm LED will give you an image.
