HN discussion> PS. This makes me wonder whether and to what degree the structure of the brain's connectome might be a necessary prior for AGI. I've seen an analogy in hardware that is potentially interesting to explore. There is a technique in A/D converters (ADC) where input signal noise can be reduced by RMS averaging the sequence of digital outputs. This increases the effective resolution of the ADC, while lowering the effect…

HN discussionIf you _must_ use I2C, then look at SMBUS if its an option for the parts. I2C's biggest failing is that there is no protocol level timeout, so one stuck device can block your entire bus unless you have a reset line for all the peripherals on it. https://www.analog.com/en/resources/design-notes/guide-to-co...

HN discussionGlad you're open to feedback. I don't know if your regulator response was directed at me or someone else, but using that as an example, if you take something like an LM7805/LM317 I think the 'parameterization' you're talking about (i.e. "input_voltage=12V", "output_voltage=3.3V", "accuracy=5%" --> let "tool" solve for resistors, and populate schematics/BOM) sounds cool and would work. But what if it's something like…

HN discussionLooks quite neat, but as other have pointed out I do not really see how this is different from traditional HDL languages such as verilog and VHDL. I say this because by looking a bit into atopile examples I only saw easy "digital" circuit stuff with GPIO and resistors, which are all things that can be implemented using FPGAs. However the most difficult things when designing advanced PCBs are EMC / EMI [1] problems w…

HN discussionOP, cool project. I have questions though: How does the device detect very short bursts? After looking up the data sheet of the RF detector I believe you would need additional circuitry to not risk that very short bursts slip through the sampling of the ESP A/D input. Second, the supply voltage of the detector seems to be 3.0 V to 5.5 V, https://www.analog.com/en/products/ad8317.html

HN discussionOne of the fun things about signals theory is how the same basic concept will show up in apparently unrelated places. Example from electrical engineering: microprocessors will have a "clock" frequency, say, 16Mhz. But when you haul a wire up to VCC and pull it back down to ground, some amount of the power will be radiated away as radio waves. If your clock is at a constant rate, then you'll have a big spike of radia…

It's been a few years since I worked with them, but the compiler had a "native" and a "compatible" mode -- the first where `char` is 32 bits, the second where we multiply each pointer by four before exposing it to C so we can pretend that we're addressing individual 8 bit char elements within the 32 bit hardware word. Much less…
