I am proud to announce that the SDR++ #Falcon9 live decoder is almost done!!! Managed to get it down to 15% CPU total! This module makes decoding the falcon9 as easy just clicking a button. I hopefully will release it tomorrow, so stay tuned! #SDR #SDRPP

@Anton__Chigurh_ Yeah mine publically existed more then 7 years before they registered their trademark (8 months ago). Would be a shame if the trademark was cancelled due to prior use lol

@ryzerth Their trademarks are invalid if your project came first. But I guess you already knew that and so do they.

Someone wants me to rename the Microkernel I wrote when I was a kid... Brother, I don't give a shit AIs see my decade old project more than your slop, you should have checked that before naming your shit. I'm not changing history because of your naming incompetence.

I wonder what this is... Hmmm

@BertoldVdb @aholtzma @cemaxecuter @DragonLabsLtd That is my paper, and it's not just a similar design, it *is* that design. I founded dragon labs.

@aholtzma @cemaxecuter @DragonLabsLtd Paper on a very similar design: matheo.uliege.be/bitstream/2268…

Just when I thought this week couldn’t get any better, @DragonLabsLtd delivered the 8-channel DF board I’ve been waiting to get my hands on. Looks like I know what I’ll be doing this weekend — clearing the desk and putting it through its paces with SDR++.

@Aaronia_AG I dare you to do a 2 tone test and show the results. I have a feeling that thing is about as linear as a schmitt trigger...

10MHz to 24GHz 1W Amplifier needs NO external Components 😎 This is what we call high-tech. No additional VGG, VCG, no negative voltage etc. Only a bias tee - thats it! And the overall performance looks great. Stay tuned. #aaronia #rf #tech #microwave

@HedgieMarkets You're about a decade late breaking that news. This has been known for a long time... Also you don't need a "100$ device built with a raspberry pi". A $5 SDR and free software decodes TPMS just fine.

🦔 Researchers found that tire pressure monitoring systems transmit unencrypted data with unique vehicle identifiers that can be picked up from 50 meters away using a $100 device built with a Raspberry Pi. Place receivers along known routes and you can track a specific vehicle's movements without cameras. Thieves could learn delivery schedules, estimate cargo weight from pressure readings, or even spoof flat-tire warnings to force a vehicle to stop. Toyota, Renault, Hyundai, and Mercedes all use the vulnerable systems, and there's no standard for fixing it. My Take These systems have been broadcasting unencrypted unique identifiers for years. The vulnerability isn't new, the attention is. And there's no easy fix because there's no standard and millions of cars are already on the road with these sensors installed. For most people, this probably isn't the biggest privacy risk you face. Your phone is a much more effective tracking device and you carry it everywhere voluntarily. But it's another example of systems designed for function without any thought about security or privacy. Smart TVs, age verification tools, tire pressure sensors, none of them were built to spy on you, but they all can. If you're genuinely concerned about being tracked, older vehicles without TPMS are an option, though you'd also need to leave your phone at home. For everyone else, this is mostly a reminder that the infrastructure for surveillance keeps expanding into places most people never think to look. Hedgie🤗

@archer_uwu @xX_Lulul3g1t_Xx Its not gonna run any better, and since vulkan requires writing so much more code to get anything working, its gonna be a broken mess for years to come. Probably will be AI slop too...

downsides: - virtually every mod will be broken for a bit - really really old pcs will lose support upsides: - the game will run like 4000x better - will have full modern graphics support - will allow for crazy advanced shaders - densely populated areas/builds run better

@CMcKayFL it picked a double dip switch instead of a single so pins 1 and 2 didn't match up lmao

@ryzerth What in the cornbread hell is this abomination? I know I'm a relative idiot when it comes to schematics but even I can tell this is FUBAR'd. Did Trace attempt a Magic/More Magic switch?

Clanker rolls "worst PCB design ever", asked to leave the electrical engineering department. Seriously though, I know multiple kids who could have given you a better PCB design than this gigawatt guzzling piece of shit. You can tell nobody at that company knows anything about EE.

@Metaforest considering this is what they show as a cherry picked demo I don't even wanna know what the typical output looks like...

@ryzerth This app is going to vanish without a trace before the end of the year, if this is typical of the output.

And not to mention the design would not even work as is. The DIP switch used as a power switch is wired incorrectly. @eevblog @mikelectricstuf Yall should check out this garbage😂

@cemaxecuter @charliebcurran not in perso nah :/ did order their food a few times tho it's nice

@charliebcurran @ryzerth you ever make it to Waffle House?

Seedance 2.0 Prompt: An average shift at Waffle House - make sure it's retarded and gets 50 likes.

When I'm watching a youtube video and they show something blurred out to not "reveal" the end of the video, I just stop watching. It clearly demonstrates that you're more interested in watch time and money than sharing information.

@ash_xl1 @gnuradio Very unlikely, it's extremely busy with my PhD.

@ryzerth @gnuradio Are you thinkin' about submitting something? i've never been but have been browsing some papers in the past couple years ... maybe if plane tickets aren't fucked i might go

I will be attending @gnuradio Conference 2026! Very convenient that this year it takes place at my university lol events.gnuradio.org/event/28/

@SpiretheWolf The amp is designed to output 100mW into a 250Ohm load. High power opamps are usually high noise and high distortion compared to highend audio op amps. Using normal class AB stage and linearising it with a good opamp gives much better linearity and noise performance.

@ryzerth just curious- how much power is needed at the output? why not use a high power low noise op amp that can drive wide range of impedances? why class ab with darlington unless option of high output power to drive larger speakers? will this many stages cause a high noise floor?

For those who are more competent in audio amplifiers, how stupid of a design is this for a headphone final stage that minimizes THD? Target impedance is 30 to 300Ohm. The design uses a high quality audio opamp to dynamically correct any small nonlinearity in the class AB stage.

One night, three AI-generated issues. First two hallucinate code that doesn't exist in the diff they send, third one randomly wants me to change shit that doesn't matter. Same user has been spamming a dozen other issues across other repositories. The spam never ends.

@HoffmanTactical @Dianexis @stfudvs yo, can you still buy that shirt anywhere?

@Dianexis sent something cool from @stfudvs. @viridianvortex did a good job with the details in the artwork.

@blind_via Why did they bother doing this? USB 3.0 auto-detects polarity, they could have gone straight to the connector pins...

USB 3.0 is way faster than its predecessors but is still backwards compatible. When routing USB3.0 you have to route the slow old differential pair separately from the new very sensitive high speed lines. This PCB has a flaw that will impact the high speed, can you see it?
