Pat Deegan: Maker, explorer and sometimes teacher, of techy and other things

@_phnx_1 I've got an AntSDR E200 I haven't had a chance to play with enough, yet. Am guessing it'll justwork(tm) in "pluto mode", will gladly give this a spin :D

I love the deep theory but having rough frameworks to think big picture and seeing things in real life before tackling all the details and math really helps me a lot.
My attempt at putting hard-won signals stuff into cool hands-on experiments:

@jerkeyray Def a good start, and pretty much how I got going... can get pretty addictive, you've been warned ;-)
Have fun!

Why, yes, I do want to play! Really sweet work with the FPGA breakout and SNES controller

[Rohan makes ASICs 🛠️ @always_ff_rohan]

Want to play? 😋

A game purely written in verilog.

Games are basically state machines, which is a great fit for verilog and FPGA architecture.

Amazing @hackaday europe, in Lecco. @tinytapeout team meet (nothing like inperson), time with @mithro, old friends and new, even met some really cool guy with a swiss accent. Thanks to all who came for making it so awesome!

[psychogenic @PsychogenicTech]

@LastKnightUK @tinytapeout @hackaday It's just awesome!

[psychogenic @PsychogenicTech]

Made it to Lecco, Italy, with the @tinytapeout team for @hackaday Europe, starting tomorrow. If you're here, say hi (and come to the workshop!)

[psychogenic @PsychogenicTech]

@FossiFoundation #latchup 2026 in Canadia:great talks by amazing people. Workshops tomorrow. Hosting the @tinytapeout advanced workshop (get on a chip! free tile sponsored by @_chipfoundry ) @ 10am, hope to make Nanick's analog layout @ 14h00, both tomorrow (Sunday). Join us!

[psychogenic @PsychogenicTech]

@splinedrive ooh, wow!

[psychogenic @PsychogenicTech]

Made it to and through Toronto to Waterloo for @FossiFoundation's #latchup 2026, starting today! If you spot me around, say hi!

Deep (deep!) dive into NR+, a new protocol, tech and band available for IoT. I really like the RF that makes it go, and think this gives a good look at what's under the hood, on top of some actual real world use and characterization of this open standard

[psychogenic @PsychogenicTech]

A new band & technology: license-free IoT just leveled up!
Spectrum reserved for baby monitors and cordless phones is now ours to play with--I took a look at NR+ and it sits nicely between LoRa and WiFi, to give you speed, range and low latency. Full investigation coming @ https://t.co/sTOK2il3CB

@thegertel @matthewvenn I'm guessing the heat might be easy bring in but tough to dissipate ... more data coming soon :)

Nice illustration of the dark side, btw !

[psychogenic @PsychogenicTech]

Blast, I'm responding to the wrong post. See the repost of my graph, above (the RP2 temp sense data) where spikes at the top of the data, when it gets hottest -- that must be direct sunlight. But then it dips night when it's in theory exposed to light and shoots back up to the max, before starting to dip back down as the planet shields it from the sun.

[psychogenic @PsychogenicTech]

@matthewvenn Nice! I want to get data for a full rotation or two, along side the RP2 temp sensor data--I'm really curious about the little noise in temp data we seem to get on every upswing and if the oscillator's sensitive enough to see that too.

[psychogenic @PsychogenicTech]

We're thinking the sat is spinning slowly (HUNITY's gyro data seems to say so) and that this is actually being captured in the temp, in those two big peaks (and somehow maybe that blip at the beginning of the upswing, but I'm having trouble with it... reflection, heat from Earth, ??)

[psychogenic @PsychogenicTech]

If I'm parsing the results right (the sensor experiment was by Mike Bell), these temperatures aren't all that bad--about -40 to +50C--considering the module is out there in naked on an arm extended out in vacuum.

[psychogenic @PsychogenicTech]

Data... from SPACE! Received our very first chunks of results from my spasics module we sent up to LEO with a @tinytapeout ASIC aboard the HUNITY pocketqube. This is temp sensor data from the RP2040 used to command and control the experiments. All data sent/rcvd at https://t.co/dbAeXcXvrq
