Solder Assembly – (part 1)

Afternoon Peeps – just a  quick  Step by Step Solder assembly for the Bright Pi (long overdue) – please follow instructions carefully.

The Bright Pi Swag Bag is quite fun to open – take care to separate LED’s; 8 IrLED’s loose in big AntiStatic Bag, 4 Superbright LED’s in smaller component bag.(don’t loose those nylon nuts&bolts)

 

Ok – so lets identify theLED’s and the Positive/Negative leg (anode/cathode); long leg positive and short leg negative – see below. Also it is VERY important to keep the InfraRed’s separate fro the Superbrights as they go in separate ‘slots’.

LED pins

Long leg positive – Short Leg negative as a general rule with LED’s (and Electrolytic Capacitors)

Bright PCB

This is the SOLDER side of the Bright pi PCB (for the LED’s) All 8 IrLED’s go in the centre ring around aperture for PiCam.

The PCB screen is not marked in the ‘conventional way in terms of +/- for the assembly of the LED’s in the main because of the tiny gaps around the solder pads etc. So I’m going to show you the correct placement of the LED’s here:

There are what appears to be ‘2 arrows’ pointing towards the NEGATIVE solder pad for the LED (cathode). Insert the short leg of each LED in that pad as shown in this pic for correct placement.

I suggest you carefully place and solder all of the IrLED’s first to avoid any mixup with the SuperBright LED’s in the smaller component bag.

Cut the legs of AFTER soldering as close to the PCB as you can get; optional carefully file the sharp edges off the reminding pins . Face pins / legs AWAY from your face when cutting.

Insert SuperBrights in the same fashion – short legs to go through the holes appearing to be marked with ‘arrows’ (its actually ‘the flat side’ of the LED).

Right nearly there – this time we’re going to solder on the other side of the PCB: As you can see it is really cramped around the LED’s (clever routing and design).

The L-shape connector is soldered from the front of hthe PCB, ‘black box’ indicates GND.

It has to be said because of the tight spacing and slim solder pads this is NOT a beginners project, you need a steady hand and some previous solder experience. I’ve had great fun making this though and really looking forward to producing some stunning footage and images with what essentially  is a killer accessory for the PiCam.

Taadaaa – with ‘intermediate’ solder skills and a steady hand this is a 15min solder job !

 

BrightPi/PiCam assembly and User Trip coming up soon so stay tuned !

  1. Looking forward to the next assembly part :). Also the white LED. What is the use for? Because you already have IR LEDs right? Im just curious to see the results :D.
    Also do you know if the rasberry can handle 2 camera´s with bright PI´s?

      Thanks for your input Matthijs , much appreciated !
      No it is not possible to run 2 cams on a Raspberry Pi at the moment. I am working on finishing quite a few tutorials – just finished organising a Raspberry Jam myself – so been a bit busy 😛
