Re: Picking the correct LEDs for modules

I find diffused to be the way to go. Generally varying the series resistance can only go so far with dissipating the light.

Re: Investing in Chips - e.g. THAT 300P14-U

If you plan to utilise these in designs, then I would buy what you can now for these designs as who knows what the price will be with inflation in N years.

Am I correct in thinking that the reason my Intellijel VCA accepts and responds to negative cv is if you have the attenuator full open then negative cv will turn it “down” - while running audio through it? I guess the same would apply if I was running voltage through it, the negative cv would atten...

Re: Waiting for an Optomix...

The whole semiconductor industry has been hit hard... this would impact the distribution of restocking many items, not only the integrated circuits that might be contained within this module, but the modules themselves including any subsequent components.

Re: Plaits stencil for solder paste

As bgreeves mentioned, JLCPCB offers stencils for cheap. Changing the size, impacts the final shipping cost due to the weight incurred. I get a stencil for every prototype version.
