The resistors and the LDO costs in serial production less than 20 cents so why not stick it on it
Of course a sort of LVP like I am planning on my tail boards would be possible as well, but that costs like 0.6$ more
But pogo pins do need some support, they are long, thin and bendy. Which is why I suggested a 3D printed support.
Perhaps a big dollop of hot glue might suffice.
Back in the day my kit was designed for ATE on a GenRad/Teradyne bed of nails, with guided probe for detailed stuff. Everything made extremely precisely and solidly.
Not necessary for a torch. Just a common flashing interface.
I fear, you won’t have fun soldering pogo pins aligned with your design, lexel, something like this with a notch for automatic alignment might be better. Was still difficult to solder though, especially with iron, I was successful with hot air finally. But hot air might cause problems with a 2-sided design.
I’m hoping Hank might offer a flashing kit too, but I don’t know if that will happen. For now, I could stand to get some pogo pins (or really any pins) to put into my ribbon cable, since I haven’t had a chance to try out the flashing pads yet.
The pink surface-mount LEDs are nice. I built a clock with those… one LED per pixel.
I’d love to see a mixed LED board with two resistors to adjust the relative brightness of two channels. They’d both still be on at the same time, like the current design, but the colors could be a lot more interesting. Like doing half-and-half with royal blue and photo red emitters, to make a really vivid purple.
But TBH, I don’t care all that much about the aux LEDs. I’d much rather have the option to get a primary MCPCB with two LH351D 4000K 90CRI and two LH351D 5000K 90CRI emitters. I think that would be just about ideal, both on the D4S and the original D4. This sort of mixing doesn’t work as well on a triple, but a quad is a perfect host for it.
