Spectrum Next Blinkenlights…More progress Inserts

The CAD for the clear plastic parts of the inserts is coming on well. I’ve just ordered a handfull of these to be Resin printed…..

Some extra features –

  • 339 small 0.25mm dimples to help diffuse the light!
  • Strain relief for the PCB – the two slots on either end will help slightly mis aligned PCB’s to sit in the cutouts
  • Much thicker top layer to help with light diffusing

Spectrum Next – A little distraction – Push Push SD card?

specnext PCB PUSH PUSH 2

Had a little bit of a play with the daughterboard to see if there’s any possibility of putting a ‘push push’ SD card inside…

Unfortunately it isn’t without chopping at a couple of supports inside. I’m trying to keep my Next case fairly minty – untill it’s possible to get another, i’m going to avoid this mod.

The reasons it won’t fit – The case was designed with two ‘helper’ guide rails for the SD card – shown in yellow in the images above. Those rails stop any push-push mechanisms from working – there’s just not enough mounting depth for the card reader.

Now, if someone were prepared to snip those rails off….then it’s entirely possible to knock up a new daughterboard……I’ve already done most of the EDA before I thought to take the next apart and check 🙂

Spectrum Next Blinkenlights – part 5 – More PCB’s

Specnext inserts - 4mm Hole drilled - Bottom Up looking
One idea that I may need to do –  Partially Drilling out the 1.6mm holes to a wider diameter – to allow for easier Inserts PCB manufacture

 

Specnext inserts - 3.2 mm Hole drilled - Top Down
Potential idea – drilling out the hole from the underside – you can almost double the diameter without touching the case – This could be quite tricky to get right though…

Something on the side – Spectrum Next Blinkenlights

Back a few years ago (wow, it was that long!) I backed the Spectrum Next

Problem is, those lovely coloured bars over on the righta2ql6z-spectrum-next-black-1.39

They’re not LED’s………….

Well, I’m gonna try to fix it……
