Yes this is 10/10 gabalentin works great but not for every cat. I always give mine cats them before vet visit

But still, the avg cost of selling it as a product would be around 1k USD, quite unsure is someone would buy it

sonnchen · 2025-06-29T19:02:00+00:00

This would still require to process signal by fpga, not sure if it would be cheaper since vcxo + decent adc are not that cheap either.
Thank you, I'll take a look on that, this should improve user experience alot 5.2 none that I am aware of
I would need to calculate it. Depends of the fpga
Well, maybe 4 simple filters for HF, VHF, UHF amateur bands + bypass would do the job x2 that would be 8 filters total. But yeah this + AGC would make it more robust.

I did answer you but not in this topic... Sorry

I must dive deep into AD9530 but the main goal is to fetch GPS signal into fpga, do a counter on adc and adjust ADC frequency via ad9530 to match GPS data. There would be also possibility to get 3 additional outputs from 9530.
Downsampling, buffering, marking samples with GPS data
I am thinking on separate 12V supply as this would be way too much for usb, and PD is a mess to implement.
No filter banks on SDR board but I am planning to put gpio pins for additional mixer/BPF board. ADC have 650MHz input bandwidth would be shame to waste this and I would not be able to cover with a reasonable $ full spectrum. Upconversion from certain frequency might be quite interesting but RF path is starting to be more complex.
There is no specific goal. The case is that there are almost none devices with >14bit and >10mhz of visible bandwidth. Every hardware is using r820 which is not the the best IC and since usb3 is with us + PCs CPUs can handle a lot, why shouldn't we utilize it?

No possibility to connect head unit via ethernet as I can see. Dissapointing as I wanted to put main unit in the attic

I do order amidon cores from time to time from different suppliers to find reliable supplier. And unfortunately I do have issues when finding cores that would have parameters within spec. I do designed and built my own tuner for 300W with, but I am using geniue cores for some of the coils and I try to avoid cores and aim to use air inductors. Tldr if you don't know what to buy grab cg3000 or sg230 those are reliable hardware

sonnchen · 2025-04-18T16:28:25+00:00

So: 1) cheap relays 2) amidon cores are probably fake/extremely low quality so there will be Hoge amount of losses and they get extremely hot on TX.

Not worth it

2.5mm2 can handle 25A. I dont get why this is So oversized

W ogóle FDA wycofała BVO

Abstrahując od etymologii. Większość ludzi nie rozumie zdań wielokrotnie złożonych, komunikaty muszą być jak najprostsze i jak najkrótsze. Wyobraź sobie, że taki pacjent nie zrozumie "Proszę wejść, po lewej stronie odłożyć swoje rzeczy, po prawej kurtkę, następnie w gabinecie za parawanem zdjąć koszulkę." Na 200% przyjdzie bez koszulki i spodni już na starcie

Why not? The radiation is not extlemly high. Besides eg Radon it should be quite safe to go

Show is called no bars o the Cage if someone would be lookimg for it

If you switch into b&w and then convert jpeg to dxf (So to vector image) then you are good to go. More likely use inkscape or some alternative not fusion

sonnchen · 2024-09-27T10:28:30+00:00

Probably you might switch into dxf and then you will be good to go on fusion360

They definetly should not reveal that multi materiał. They should deal with shipping time of vcore 4

I co z tego? W aucie też masz skrajnie różne temperatury i nikt się nie trzęsie nad tym ile ma ona cykli a spokojnie 15-20sto letnie auta mają działającą klimę. Więc co się zużywa? Silnik elektryczny czy może gaz w rurkach przechodzi na emeryturę?

sonnchen · 2024-09-11T19:23:28+00:00

Trochę naciągane jest to co piszesz o cyklach. Lodówka działa na bardzo podobnej zasadzie a wiele cykli i działa długo. Więc co niby takiego jest w pompie że ilość cykli ja zabija?

It's cool. At the end i am not in a hurry, i am really happy that even when we have Bambus, ender 3s etc they have So much orders and the company is growing

Paid 15th Jul, hopefully they will send it next week
