apparently wspm is Wafer Starts Per Month

guess I'm interpretting "1million wspm; add 10%; was effectively a 20-30% capacity increase" in 2015.

Not sure where 5% then comes from. Guessing "relative shrink" is referring to process size (5, 4, 2 nm, whatever) not linearly corresponding to density of transistors, etc.


Tell us more; what's driving this model as your choice? Or is it more of a "prefer getting similar to what I currently have, and this is the model that makes sense"?

I wear BTEs and got new earmolds made by phonak this past summer, but I'm in the US. I'd classify them as firm silicone, and doesn't seem 3d printed. Seems like the same material as the previous molds (which I wore for almost 8 years).

I'm asking because my mother is really unhappy with the quality of new mold and she says there's a difference in material. This new firm material rubs her auricle to the point she needs to apply some healing ointment now and then - it's a little bit too big.

Woman who accepted the order for replacement mold said that production plant uses now some kind manufacturing with printing and they also replaced soft silicone for this firm stuff. In fact it's the second new mold and despite her detailed notes on how and where to cut it so it wouldn't damage the ear, it seems they just did the job and sent it back to us.


That's certifiably not fun :(

Not that one ever should have to do such for medical equipment, but wonder if someone could grind down the firmer stuff on the first new mold, assuming it was kept...

(Not really useful anecdote:) I remember circa 25 years ago, my audiologist had a benchtop grinding/buffing wheel that she'd take the earmolds to a few times when modifications were needed. Even at that young age, it was clear that grinding soft materials didn't work very well.


I'm in a similar age range (HAs since 1991 I guess). I also have fond recollections of the pre-digital HAs' sound.

I'm using a pair of 8 yr old phonak BTEs, which have various levels of directionality focusing. (Actually, I'm down one HA; 8yr old on left; 13 yr old left one one on right ear... getting new ones in January) I too prefer a lower level of directionality as my default.

I assume your HAs are doing bluetooth for the music setup you describe? Or are you describing a setup with speakers at home?


I use Bluetooth with my phone and sometimes my laptop. My current hearing aids can stream directly from devices with Bluetooth LE audio; no relay dongle necessary.

But at home I often use telecoil. It's one of the killer features for hearing aids that no one seems to know about. Short-range (inches to a few feet) baseband analog radio.

I have a transmitter set up in the living room. If I come within a few feet of the couch I'll hear the television. Got another at my desktop computer in the office. I also have a loop I put around my neck when I play my electric guitar. Telecoil transmitters will plug into any standard line audio source.


I haven't used telecoil since I had analog HAs, probably. I learned about the even lesser-known DAI (direct audio input) option before I got my first pair of digital HAs. Since then, I've used cables, and almost as long (15+ years now) have had modified pairs of bluetooth headphones:

Sadly, it seems modern Phonaks (and probably everyone else) no longer makes DAI "boots" for their BTEs.

I'll probably be ok with the transition, but it's going to annoying having to recharge hearing aids during the day. Right now, I can get 6+ hours of music/podcast/meetings/phone calls on my (5+ year old) headphones batteries, and can take those off and charge them when not using them. (and other perks...)

I'll have to refresh myself on telecoil to see if it's of use. (My BTEs still have it, iirc)


My pushing was failing for reasons I hadn't seen before. I then tried my sanity check of `ssh git@github.com` (I think I'm supposed to throw a -t flag there, but never care to), and that worked.

But yes ssh pushing was down, was my first clue.

My work laptop had just been rebooted (it froze...) and the CPU was pegged by security software doing a scan (insert :clown: emoji), so I just wandered over to HN and learned of the outage at that point :)


A niche usecase: it switches to a bluetooth connection instead of a usb dongle.


It has a USB wireless dongle that doubles as a charging dock with magnets and pogo pins


Indeed it does, I now see. Interesting!


The old one also used Bluetooth.


The old one used Bluetooth if you upgraded it during the transition period or you have a Windows box.

I had to borrow a friend's computer to get mine to run in BT mode because I gave up using the Steam Link fairly early and didn't use the controller again until I bought a Deck, by which point the grace period where a system update fixed it had long since expired.


My usecase for the steam controler was limited (robots); I've always used the dongle, and never needed/desired to explore direct bluetooth as an alternative.

I assume that the extra regular (daily?) cycling of the battery in your car would have a notable effect on your vehicle battery's longevity. (But I'm very fuzzy on how battery improvements in the past ~decade have applied to "cycle life", or really even what the cycle life means, e.g. is end of life when it's something like 70% of total original capacity?)


Having had a chance to read more of the blog now, maybe the most pleasing part is your similar discovery of, "I'm writing my own kinematics, and generating plots of it is the fastest validation of that code". I did similar matplotlib plots of my quad (spider) leg movements years ago. Definitely need to do more of that when I finally revisit the software on my mech from 2019 with AI help :).

And more generally, yeah, having the AI manage some of those plotting needs will be fantastic in other work too; I enjoy figuring out what to plot, and don't mind wrangling and hand-refactoring said scripts... but it's so time consuming historically, and there's always the itch to urgency to get back to the "main code". (at least I learned to gradually convince peers that often plot scripts should be commitable without being polished; they're a form of documentation sometimes!)


OP getting this robot working in about 3 months was insanely impressive.

what is the no gimmicks rule?


I can't quote it offhand, but it's stuff like:

- Don't stick your camera on an arm and poke it around corners to see the opponent

- No detachable parts? It's more nuanced than this. Not leaving "mines" I think is a case of this.

Basically there's a few goals to the rules (this has been an on and off competition for about 15 years now): keep the spirit of "pilots in giant mech robots" (loosely 90s era stuff), and homogenize the competition slightly for competitiveness.

Melee is still allowed! If you walk into the other robot and trigger one of their 4 score panels, that still counts.

It's a hard competition to prep for. Numerous bespoke HW subsystems, software, budgets that grow quickly with the size/weight of your bot... and being reliable.
