<p>Few years ago I did an educational project to extract waveforms from logic capture - it was doable [1]. But this approach may have limits on newer faster FPGA based controllers.<p>[1]: <a href="https://github.com/prashnts/betty-epd/blob/master/notebooks/15-17--logic-analysis-spi.ipynb" rel="nofollow">https://github.com/prashnts/betty-epd/blob/master/notebooks/...</a></p>

<p>> packet-loss<p>For one it can adequately show if your WiFi is performing well...<p>In a home network setting I've got a UDP display sink (64x64px, RGB) with a custom protocol. It works fine-- no hard number as the performance varies based on other factors, including congestion. I've been able to push it to >90fps, but around 42fps there is virtually no flicker.<p>For context in my protocol I use all 512bytes, with 3 first being the "line number and such" data and the rest containing ~128 pixels.</p>

<p>I would give the LLM statistical tools that work to find general anomalies, distributions etc. from the spreadsheet. Then it's about an LLM interpreting (or not) those results in natural language.<p>Of course this is a can of worms for a product because we can still not guarantee accuracy.</p>

<p>What really helped me was doing some sessions with an Orthoptist to reeducate my eyes. I used to see double when stressed sometimes and could never imagine to converge/cross my eyes and retain focus. 
With the reeducation I was able to see the Impossible one in focus after a couple tries.</p>

<p>Sorry but at home I would like to connect to <i>my</i> WiFi, with my preferences and access to my local network. The last time I was forced to use a common access point was in my dorm at the university, and even then I bought a small travel router to rebroadcast the AP.<p>But I do understand what you mean. I guess one thing to do is to set the router to not broadcast at full power, and use 5GHz to limit the range.</p>

<p>A good read, thanks. I like the description of take/give sides and it's well portrayed.  I wondered if there's any take home message here for salvaging a give-take conversation.<p>I'd crudely deduct that being takers/givers in a conversation may be a function of cultural, linguistic, social, and intellectual dimensions coupled with personal, emotional, and ambient states a person is in.<p>As such there's really very little just one party can do to have a better conversation flowing on their own. So apart from affordance, I think participation seems to also be a key factor and can be seen as "push or pull or slide" aspect of that doorknob.</p>

<p>M5Stack sells some really good quality modules and I think kits as well. These work fine with Arduino, and also with their own UiFlow software.<p>The advantage I think with their products is that you only need to connect wires in general -- soldering and stuff is optional. They have good UI on hardware, and even include touchscreens, buttons and so on.<p>I think it will meet your "mostly fun" for sure!<p>Technically it's not Arduino in a sense that they mostly use ESP chips (not AVR), which is supported by Arduino IDE.<p>The homepage has good pictures  if you want to get an idea: <a href="https://m5stack.com/" rel="nofollow">https://m5stack.com/</a><p>(Not shilling :) Just really like their products!)</p>

<p>Cheapest version is 31$. Without internal pullups. Which means it's basically gonna bit-bang if you want to interface with SPI, I2C etc. I'd consider a raspberry pi even if it costs more because it has a _lot_ of I/O capabilities and starts at 5$.<p>For a comparable option, consider one of the Pi-Picos, Arduinos with VUSB, or a USB-Serial board with extra GPIOS.</p>

<p>Long time reader of your blog, thanks for doing what you do!<p>So I've been into "connector technologies" (if that's a thing) for a while -- more specifically I really admire the simplicity of edge connectors that nowadays are basically free (except the higher amount of metal than traces, (gold?) plating etc.). Anything you'd like to add about these sort of connectors from this era? Were they reliable in mating-cycle sense? Could you just casually insert them or was there a specific process? Was there a standard?<p>As you can see I don't have a precise question, I'm looking  more towards the considerations that an engineer at that time would have to take into account. Unfortunately it's not very easy to google this these days.</p>
