Shameless plug - https://foldmation.com

Big backlog of folds to approve seems like it's ignored. I'm in the middle of fixing some rendering issues hence I haven't approve them yet. Rendering fixes and fold approvals should be up in a few weeks.


Same post was just asked yesterday https://news.ycombinator.com/item?id=48514461

Try the RAZR style folding phones. It trades length for thickness which is a godsend for me. I hate how unpocketable phones has been ever since like 10 years ago.

A carrier bot can be parked near the stairs to transport the bot to different floors

Page doesn't say, but I'm guessing with help from AI


Brief search reveals prior academic research related to sexual orientation and dating apps. Doesn't appear to have done anything in maths before.

But then, why were they the first to issue the correct series of prompts to produce these results?

This would lend credence to the efficacy of using LLMs as tools. If mathematicians in the packing field had used the tool before this liberal arts student, they'd have their names on the record page.


I go by comments count, so wish that count stands out more


The face and eyes with the chainsaw looks so satire. Is that how you got the name? Hope you are getting enough sales as it does look useful.


90ms is absolutely not an acceptable delay. On a 25mph road, each 90ms is .0006 mile ~= 1 meter. Latency goes both ways, so that is a possible 1 meter before operator reacts and another meter before the corrective action takes place. Like other comment mentioned, remote operations can only be used for high-level instructions (or simpler highway driving).


Thank you, like and agree with the rest of the rules


Can you explain what makes the Brompton design genius?

Edit: the top comment (at this time) has a youtube link that shows it fold/unfold in like 8 secs. I can see the genius in it now


Most of the parts are proprietary, so if you bork a derailleur you get to wait 6-8 weeks for a replacement from the UK


Yes. Now if you live in a metro centre and are considering a Brompton purchase, this may be less of an issue if you have a handful of dealers … in-stock common parts availability is a good pre-purchase question to ask. It’s a big ticket item.

I cracked the housing on my proprietary Brompton shifter (made it nearly non functional) and the part was actually available in local stock … but I chose to JB Weld epoxy the crack instead and it’s probably stronger than stock now.


Not sure if it was my comment https://news.ycombinator.com/item?id=47907337 which does have a video like that. But, the Brompton folding design:

- folds in 3 pieces (tri-fold) instead of folding in half (bi-fold). It was innovative at the time, is more common now. That makes it fold smaller than bi-fold bikes.

- keeps the oily chain and chainrings in between the wheels. Some other bikes which only fold in half have the oily bits on the outside[1], and/or the chainring sticking quite far out[2]

- When folded, the mucky main wheels are lifted off the ground by the little roller wheels[3].

- Brompton folds into almost a square which can stand up on its own, or pack reasonably neatly into a box, bag, or trunk. Other bikes can be more pointy, less convenient shapes when folded. e.g. [1] the bar grips stick out, the pedal sticks out the other side, the front chain ring sticks out.

- Brompton is useful partially-folded. With just the rear wheel tucked under it will stand up on its own. With just the seat or just the handlebars unfolded it can be wheeled around on the little roller wheels like a suitcase. It can be folded while leaving the front bag on without the bag going upside down, and with the bag accessible to wheel around using it like a shopping trolley.

- When folded, the top-tube of the bike is along the top of the fold, so is the seat, giving decent balanced places to lift and carry it like a suitcase.[4]

- One side has a folding pedal to tuck it away. The other side doesn't. I just think it's neat.

- Maybe goes without saying, but it can be folded without tools instead of being disassembled. Full size bikes can have joints in the frame so they come apart for packing for travel, but you just get a pile of separate pieces. Some medium size folding bikes need a wheel removed and only really fold for packing into a car, rather than something you'd do on the fly for a train trip. "Folding bikes" is not unique to Brompton, but in the market of "all bikes which can be made smaller", folding was a thing Brompton made mainstream, partly by inventing a fold that was so convenient.
