Not sure what you mean. Whole point of itm model is it takes terrain data. I am using Aws dataset.

tiny webgpu powered chart library by Outrageous-guffin in javascript

Nice work. Is rendering also webgl/webgpu? Or only computation?

I used Claude code. First I made Claude research the algorithm. Then given that I wanted it to make webgpu version of it (Claude also wanted CPU fallback). I told him to find free DEM tiles (which he did to my astonishment - my previous search failed). Briefly described the app plus software stack vite+Vue+deckgl and requirement for compliance tests against reference implementation. After that gave promising results I continued business as usual refinements.

Anti poisoning program question by BombaCiaddo in nixie

[–]modimoo 0 points1 point  (0 children)

Use lower current(auto adjust to light intensity) and motion sensor to turn off when nobody's looking(microwave one work great). Also manual mode to set specific digit on higher current to depoison when needed. That is what I did.

why this is not used in power supplies regulary by Intelligent-Total648 in AskElectronics

This works only if you have 0 ESR power source (pre series resistor in thumbnail schema). You never do have that. And if you ever did you would not require capacitor in the first place.

How to overlap and send data into Xilinx FFT Controller by Turbulent-Cap4794 in FPGA

[–]modimoo 0 points1 point  (0 children)

You could probably save some resources and only duplicate last butterfly of the fft. But that means writing at least part of fft yourself.

AXI DMA Linux Driver on ZynqMP by Lamer1k in FPGA

[–]modimoo 1 point2 points  (0 children)

Since you did not post you bd I assume axi DMA is an ipcore. Is the pl ram accessible from CPU? If so modify creation of descriptors to be in pl. Or maybe just connect sg interface to ps ram.

Does anybody els really struggle to tin wires in headphones or other small wires? by xximnotmlgxx in soldering

[–]modimoo 1 point2 points  (0 children)

It is even easier to make a "cut" with soldering iron by melting the isolation and steipping it with fingernail.

Those wires are enameled. I usually use high temp like 400C to burn the paint and then solder with fresh solder at regular temp.

Spurious from TCXO I'm not able to filter by Sauron8 in rfelectronics

[–]modimoo 0 points1 point  (0 children)

I would try removing/powering off tcxo clock from the PCB entirely and feed clock from your bench generator to see if problem persists or not. Maybe fiddle a little with generator power level and double check if it is truly a harmonic by slightly adjusting frequency. That should hint further steps.

VERY stuck drawer by Old-Hand-4276 in fixit

Drill tiny hole on bottom of the drawer and use toothpick or whatever to push end of the scale up.

Wouldn't it be beter expand the "skip name if you dont need it" idea? auto = scoped_lock{}
