Spectrum Next Blinkenlights…More progress Insert PCB’s and first (second) light!

Now with 8 LED’s worth of goodness!

Due to my previous goof-up of having made the old LED insterts ‘backwards’, I designed new ones!

They’ve arrived and are all round much better

  • Slimmer – just 2.2mm wide
  • 8 LED’s!

Here’s what they look like – the features are a bit too small for JLCPCB to handle on their mass production – their mill uses a 1mm bit – guidelines are minimum of 3mm between milled out slots

I’ve ordered 50 of these – should be plenty to fill up the 10 prototype control boards i’ve gotten made and leave a few over for experimentation / errors

There’s a small problem however with mousebites this small – each board takes a good five minutes or so of dremmeling to get ready!. I can do about 7 boards to a charge of my battery powered cutting tool….I’ve ordered 50 prototype PCB’s so that’s lots of minutes of work ahead! good thing we’ve a handful of N95 facemasks picked up from back in March just as the world went loopy!

Here they are in all their glory, powered up the RIGHT way round on a controller PCB.

I hand soldered all 4 of them using some new (expensive) solder paste,d 3 worked first time! the last one had two LED’s mis-aligned…Quite a good improvement!

Each insert so far on the prototype is taking easily 20 minutes from receipt of parts to working device. Each new controller PCB is taking over an hour of soldering and wire cutting for the quick contacts. That should come down quite a bit once i’ve figured out a process.

First Light INSIDE a Next!

Yeah, spot the mistake 😛 Still, quite chuffed – these are powered up and working INSIDE the next! –

There’s no control YET – this is just a single routine that runs upon powerup in the Arduino….

IT’S ALIVE!!

And, just as a final superb moment – look at these results of a quick i2c Scan (there’s a lot of numbers due to using an HDMI monitor)….That 3rd Device at address 0x45 – That’s the Spectrum Next Super LED Blinkenator 2000 just waiting for a .DOT command to control it 🙂
