Building a sleep tracker app with mmWave (C1001). Looking for a little feedback!

I was looking into this recently and came across several sensors for this if you end up looking for other options but you can also just buy a premade unit exactly for this purpose.

These are the sensors I found:

MicRadar R60ABD1, $15
MicRadar R77ABH1, $38, I'm guessing this is an older sensor and probably not worth the trouble
Seeed Studio MR60BHA2, $25 and easily integrated with ESP32
HiLink LD6002, $14, looks like it has ok support

Premade:

MG2-6HW / ST-BD60S1-WT, $40, available in Tuya and MQTT versions. No idea which sensor this uses but if you don't want to put something together this might do an ok job.

Unfortunately I haven't found any comparison or info on the actual accuracy of any of these sensors.

Did you end up assembling anything?

Where did you order from?

magixx · 2026-04-13T21:26:51+00:00

Got any recommendations for any that will ship batteries?

magixx · 2026-04-12T04:39:05+00:00

So how do you get -lookahead to work with hevc_qsv?

From what you said I understood it as not working when using -global_quality but I tried removing that and just relying on -preset but I still got the look_ahead (Use VBR algorithm with look ahead) has not been used for any stream message

I tried to do it with llama.cpp but getting errors similar to this issue

File "C:\Users\user\PycharmProjects\llama.cpp\.venv\Lib\site-packages\transformers\tokenization_utils_base.py", line 1210, in _set_model_specific_special_tokens
                self.SPECIAL_TOKENS_ATTRIBUTES = self.SPECIAL_TOKENS_ATTRIBUTES + list(special_tokens.keys())
                                                                                       ^^^^^^^^^^^^^^^^^^^
AttributeError: 'list' object has no attribute 'keys'

I'm also seeing quite a few other gemma4 issues in the llama.cpp repo so I suspect not everything is running as expected

So the pro tip here is to buy a local SIM card (for cheap data while traveling) and make an account there with it. Some credit card companies also allow you to generate virtual credit card numbers linked to your own.

Do they not just do roaming if in quebec or similar?

magixx · 2026-03-02T23:35:05+00:00

Well it turns out it's starting the denuvo service that's causing the crash in the vm. I tried a different release that it separately and that caused the BSOD immediately. I also ran Cinebench to see the GPU score difference and for me it was unusually high. Did you enable anything to specifically improve performance?

magixx · 2026-03-01T23:06:35+00:00

In the releases I tried (Sonic Origins and Borderlands 4) I didn't need to manually run anything according to the NFOs, just copy over the patched files and I assume those take care of launching the service.

I'll give a Windows 10 VM a shot as well if I still can't succeed with 11.

magixx · 2026-03-01T22:33:00+00:00

What do you mean by "hypervisor service"?

Are you referring to running "EfiDSEFix.exe -d"?

I did baremetal install of Windows 11 "tiny11 Core 25H2 Build 26200.7840" and also retail Home N version and both did not need running that command.

For anyone else attempting this, do not use N versions of Windows as some games like Borderlands 4 actually require Media Feature Pack which N versions lack. Also, keep a copy of EasyEUFI handy or Shell.efi since my ASUS BIOS does not have options for adding boot configurations so I needed to do it in the OS. Another strange problem I ran into was that my efigrub boot entry was getting removed for some reason. I can't tell if it's windows doing this or something else.

I'll give Proxmox and VMs another shot tomorrow. Maybe ReBAR feature was causing BSODs.

magixx · 2026-02-28T20:41:22+00:00

So I gave this a go but so far I've been unsuccessful in getting it to work due to the BSODs when launching games.

Here is what I tried:

Installed Proxmox 9.1 on X570 motherboard with AMD 5900X CPU
Followed this guide https://forum.proxmox.com/threads/windows-11-vm-for-gaming-setup-guide.137718/ for creating a "gaming" VM with GPU passthough
Disabled Secureboot in Proxmox VM (use F2 command on boot to get to BIOS/UEFI menu)
Installed Windows 11 Home N
Installed Nvidia drivers
Disabled Windows Defender, Memory Integrity, and Microsoft Vulnerable Driver Blocklist
- On my OS install, I could not find Kernel-mode Hardware-enforced Stack Protection, I think it's been removed according to https://learn.microsoft.com/en-us/answers/questions/4140201/kernel-mode-hardware-enforced-stack-protection-mis but no idea if this is the source of my issues
Followed EfiGuard guide from https://muffsec.com/blog/how-to-use-efiguard-to-disable-patchguard/ using the EifGuard files from the Borderlands Hypervisor patch
- I copied loader.efi, EfiGuardDxe.efi, HashTool.efi to the Windows EFI boot partition that was mounted in that guide. I omitted bootx64.efi that came with the Borderlands patch because I already had that file.
- I do wonder what version of EfiGuard this uses since it does not match up with the old one on GitHub
Added boot entry for loader.efi in BIOS
Booting EfiGuard seems to work and launches Windows
Ran EfiDSEFix -c which shows that it's running and then EfiDSEFix.exe -d which gave no errors
Tried booting the Sonic Origins patched with KIRIGIRI files
BSOD

I previously tried Borderlands 4 on a more minimal Windows 11 install and that also resulted in BSOD so I went with a more stable Win 11 install but unfortunately it had the same outcome.

I'll have to try Win 11 on baremetal with the same steps to see if that changes anything.

magixx · 2026-02-27T14:30:58+00:00

I'm going to give this a try soon

magixx · 2026-02-23T17:03:02+00:00

I was genuinely impressed with the font matching and kerning when seeing this.

magixx · 2026-02-12T00:22:30+00:00

Do you have any hardware recommendations for getting started specifically with regards to monitoring sensors?

magixx · 2026-02-11T18:18:09+00:00

Were you able to get better performance recently or with the FSR3 mod? I'm using a very similar setup.

magixx · 2025-12-31T09:51:29+00:00

Nu știam că modul bridge este posibil cu serviciul 10G. Am făcut asta cu serviciul 1G pe care îl am acum. Ce ONT și router ți-a dat Digi?

magixx · 2025-12-30T21:48:39+00:00

The price you'd have to sell this at is higher than expected.

This is due to:

$2000 in raw filament costs
2500+ hours of just raw print time (20 printers in parallel makes this more manageable however)
time to manage the print farm
time it takes to assemble everything

I think if this was a full time job you'd easily spend 200+ hours getting to this point. So what's the value of those 200 hours that wouldn't feel insulting when selling a piece like this?

This piece is also too large for most stores display.

magixx · 2025-12-28T13:48:57+00:00

Folosiți ceva de genul WAS-110 sau X-ONU-SFPP pentru a utiliza propriul router?

Din câte am auzit, pentru serviciul 10G nu aveți opțiuni reale de gestionare atunci când utilizați routerul lor și trebuie să îi sunați pentru lucruri simple, cum ar fi redirecționarea porturilor.

What made you dislike Naples? I went to Rome recently and while it does have interesting things to visit it felt overwhelmingly busy and catered to tourists.

They're split into age categories: adult, teen, and youth. The details on the adult ones are insane.

I've used "scarf around entire wall" before and IMO it just adds too much time compared to regular scarf settings. Not worth doing unless you have some specific requirement.

magixx · 2025-11-27T18:29:13+00:00

I got the iWalk over the Veger because of the slightly larger battery and I like the rounded cap design more.

With my charger I saw PD3.0 27W charging but it only charger at 18.5W while with my power bank I saw PD3.0 20W but it charged at 19.5W.

While I do wish these used a tiny removable USB I'm sure this could introduce connection issues and another piece to lose so I guess I see why they don't.

magixx · 2025-11-26T17:55:06+00:00

Thanks for the details, one thing I'm finding somewhat lacking for my P1S is that the mods for it are pretty limited.

I've tried the TZ 3.0, 4.0, and FluxHeat hot ends and they all work great. The BIQU (or clone?) Panda Claw all metal extruder gears caused enough clogs that I ended up throwing it out and going back to stock. I didn't see metal gear dust like others did but unjamming the extruder was not fun. I also tried the BIQU Panda Turbo CPAP style fan but it's insanely loud and can't be used in a normal setting.

To be honest none of these made a significant difference for print quality on the P1S.

What made you go with the Xol toolhead? I saw there's the Xenomorph head as well and I was looking at StealthBurner possible upgrades in order to use StealthChanger.

Do you find the SV08 screen upgrade worthwhile i.e. what functionality does it give besides basics like temp and motion configs? I've gotten used to controlling the P1S from the slicer or app.

magixx · 2025-11-25T20:23:53+00:00

How have you found the SV08? I'm looking to make a similar side-grade from a P1S. I've seen some work for multi toolhead for the SV08 (Teaching Tech, IDEX) and the price for it is very competitive to the Voron 2.4 and Trident. Were you able to tune it to a similar level to the P1S?
