this is awesome. i have always wanted to build something like this. figured i would just use a regular sensor and use the adjacent pixels to calculate optical flow.

I'm not complaining - I even have a Forth pet project myself. Just noticing that it's showing up a lot lately.

Show HN: New Parts for Old Computers

Since it appears to be retrocomputing day on HN, I thought I'd post my pet project. It's a collection of modern peripherals for retrocomputers. I started collecting a list of upgrades for my ideal dream Mac SE/30 and grew from there. The site is currently mostly focused on Apple II and Mac stuff since that's what I grew up with.

Oh, this is awesome. I actually have this book. Also, for some reason, I am writing a hacking game based around fourth which has been interesting.

it is real. serial number 2. it’s a terrifying car. i can’t drive it much at my home track (laguna) because of the sound level, and it’s not eligible for most track days. https://www.jalopnik.com/don-t-feel-bad-if-you-get-passed-by...

it runs knobbly tires so just going to slicks would probably help a lot, but i don’t think the transmission is built for it.

my ae86 is caged and my s13 was a formula D car. they can be amusing

i have a '62 lotus 23, i am tempted to put carbon fiber body panels on it to lower the weight even further (currently ~ 900 lbs)

that’s a good list. i also collect japanese beaters (currently several miatas, an ae86 and an s13) and british lightweights (two vintage lotus racers and a modern aston factory race car) so lots of overlap.

i have been looking for a 944 as well. there’s a great porsche shop across from my workshop so at least it will be convenient.

i had a gr corolla for a year and sold it. the ITCC (the sealed clutch pack that transfers power to the rear) “overheats” and the throws the car into 2wd limp mode after a session and a half on track. “overheat” is in quotes because supposedly it doesn’t have a temperature sensor at all, the ecu runs a model based on other sensors (rear diff etc) and guesses that it is overheating.

still, a pretty amusing car. the traction control system is outstanding, it’s very hard to upset and you can trivially drift it around every corner. even with aggressive play on an empty track it was a incredibly difficult to spin the car. sadly it wasn’t that fun as a DD (you really have to wind it up.) i also had a focus RS (i like hot hatches, i guess) and found it somewhat boring on track and a lot more fun on the street (way more torque at the bottom)

anyway, it remains: miata is always the answer
