I contend that is impossible to make an unbiased AI. I did an AI image recognition project several years ago. It used yolo to categorize rust into grade 1, 2, and 3 for offshore platforms. When creating our training dataset, we had differen

Vindication! I’ve spent over a decade of my life putting physical interactives into museums. I have preached (sold) many museums on the stance that they should put unique experiences into museums that can’t happen on an iPad at home, to var

Thanks for pointing that out. I thought it was some sort of variation on an E-ink display because of the black and white limitation. Nothing about transflective tech limits it from full color other than price. I guess that leads me to an ev

Whatever happened to the transflective lcds that were popular in carputers in the 2000s? They seem to be a perfect fit for a tablet and I have been puzzled that no one has jumped on using them in one. from the transflective wikipedia page [

Thanks for pointing that out. I realized I called out the wrong chip. I was actually trying to call out the Max6818.

It's price is it's biggest drawback, but it is also replacing any electronics used to run the switches at 12 or 24v which gets you above the noise floor if you are operating next to something noisy like a VFD. from the 6818 data s

I guess I should rephrase. It saves all the interrupts except the one triggered at 40ms delay. For every button press without hardware debouncing, you can have 10s - 100s of 1to0 and 0to1 transitions on the microcontroller pin. This is easi

I'm a big fan of debouncing in hardware with the MAX3218 chip. It will debounce by waiting 40ms for the signal to "settle" before passing it on. This saves your microprocessor interrupts for other things. It also will work wi

I wish Supah Valves [1] were still available so I could recommend them. They use a smaller sprinkler valve as a pilot to move a much larger piston based valve _very_ quickly. That lets a lot more of your reservoir pressure get to the barrel

Impressive, but I can't foresee any project where I would pick this over the vastly more powerful PJRC Teensy 4.0 [1]. It is only slightly larger and only costs $3.85 more. [1] https://www.pjrc.com/store/teensy40.h
