Matt Reed, the Creative Technologist at redpepper who shepherded the project, explained via email: “I got all of the Waldo training images from Google Image Search; 62 distinct Waldo heads and 45 Waldo heads plus body. I thought that wouldn’t be enough data to build a strong model but it gives surprisingly good predictions on Waldos that weren’t in the original training set.” Reed was inspired by Amazon Rekognition’s ability to recognize celebrities, and wanted to experiment on a similar system which supported cartoons. He had no prior experience with AutoML, and it took him about a week to code the robot in Python.
Ah yes, the typical “Letâs leave that discussion for somewhere else” when the downsides of EVs are pointed out…

My busy season is when people are spending their tax returns and spring-cleaning, but I’m slower in the winter months leading up to that. Call me then, and I might be able to offer you a lower rate if I’m desperate for business.
It doesn’t add up like that. What *does* add up is the power. At 240 volts, you pull twice as much power at 15A.
They all have a ceramic rod or coil wrapped with nichrome wire that turn red hot. A vaccum forming table design I looked at used ceramic rods made the same way with reflectors to evenly distribute the heat. I believe all of the above (I did not verify if the table was) were UL marked.
This Kia Niro’s cargo area, in contrast, looks very nice! Interesting. Kia’s brand equity isn’t strongly convincing as a sound long-term value-driven purchase. I haven’t driven one, but it sounds like it isn’t great to drive.
My first thought was that the terminals were over torqued rotating the blocks, stretching the pins, and tearing the pads.
This seems to me that your experiment failed due to thermal failure cased by insufficient cooling and not the part itself..You stated yourself that the part failed due to thermal expansion (insufficient cooling). But it’s still a valid experiment with valid results. And you show that it’s up to the designer (or designers) to design the entire product, which includes sufficient cooling. This is one area where home designs fail – a lot.
The gate resistor will eventually short to the trace after so many cycles. It may take a while, but it will eventually happen. We had that problem years ago with a product. Resistor has to be lifted up above the trace. Traces and such seem fine for 120VAC for low current loads. Wouldn’t pass muster overseas.
Ultimately under-rating won’t solve the problem. The Chinese scammers are already putting below-rated parts in, because they assume most users will under-rate anyway, so they’ll get away with it. If, in response to that, you under-rate even more, and this becomes mainstream, what do you think will happen? They’ll just take it into account, same as ever, and the 75A parts you’re putting 40A through, because you want to be careful, will only contain 20A triacs.
It would require a molded socket attached to an edge with a standard IEC polarized C7 connector. No exposed conductors anywhere. Could embed a green light for powered up and a red one for hot into the socket molding.
