@BrandenBoucher That doesn't need the queen of FPGAs, I don't think. Might need a bit of care in board design to make sure you can drive the aggregate load current.
@BrandenBoucher Do you need your thing to work the first time?
Or is it okay if the demo (based on the off-the-shelf board) only is able to drive 200 or 500 LEDs, and then you build a custom board to be able to do 14k?
@BrandenBoucher I think you basically make one block to SIPO 8 bits, put it in a for loop to generate a few hundred of them. Clock each one from a different clock phase (or with an enable signal driven by a johnson counter) to reduce simultaneous switching currents.
If you didn't need so many I/O's it might be a CPLD job rather than FPGA.
For that matter, I haven't looked at the CPLD market for more than a year...it might be a CPLD job now.
@ThePhoton, my intent is to be able to drive 48 horizontal lines of 300 LEDs each. The current requirement isn't actually all that high. The signal is only fed into the first LED and the LED feeds it to the next one after it gets 24 bits.
Lets sing along with the police "resin in a bottle"
@Asmyldof for me these things work most of the time quite fine. When the bite is fresh, apply the heat, and some protein of whatever they injected is decomposed. Most of the time, I hear no more from that bite after this
Before they can out, by grandma used to do the same with a hot spoon
Okay, I have a rather stupid question, but somehow I can't figure it out. I'm generating white noise with a certain variance with an AWG. I'm analysing it with a spectrum analyzer to see how well it is produced (flatness and such). But I'm having a lot of trouble converting the data fro mthe analyzer to a proper spectral density. I have a set of amplitudes, a set of frequencies, an RBW, a reference level, but I am not sure how to go to power per hertz from there
Or well, I'd personally divide the amplitudes by the RBW, but this gives numbers that are orders and orders of magnitude too low
@PlasmaHH Hm, yes, although it is also complaining about that the system needs to be aligned. Maybe I will take a signal generator and make a tone at some frequency with a known power, see if the rescaling from that is sensible
@jippie Do you remember the name of the 3D prottyping/printing/milling service that was sponsored by local government / university here in Eindhoven that artists and students can use on the cheap or even free?
@PlasmaHH The three most goopy ones are solder resist
Or: The ones that harden inside the syringe in direct sunlight are solder mask
Or: The ones that don't do that are pigment
Or, the off-white red-ish one is solder stop and the actual titanium white one is pigment
Bright magenta is pigment, soft barbie pink solder stop
Don't remember which other colour solder stop I put in
@R_Misra Look at the picture of the part. There's probably one pin that's much bigger than the others. They're calling that a "tab" instead of a "pin".
Wait. If there is one tab labeled GND(TAB) but also one smaller pin labeled GND(TAB), does that just mean that they are connected? This is for a voltage regulator, by the way
And it's even possible to get C0G performance in 5000 to 20000 in single layer, but it's very expensive, on account of needing multi-layer balancing processes in the ceramic
@Asmyldof Well I just went and calculated what the resonant frequency of a 0.4x0.4x0.15 mm block of dielectric with Dk=25,000 is, considered just as a dielectric slab. Now that's got me worried.
@NickAlexeev You don't see how that might be offensive to someone? At the very minimum it plays to a stereotype ( which isn't true BTW- as most stereo types are) which doesn't belong.
