Banger. Confirmed my suspicions about flex PCBs and the viability of European manufacturing (unviable). Being able to shoot to Gaungzhou would also be useful. I've got a couple more questions - I'll dm you on twitter.

Gotcha - thanks for the advice. The IC performance on the flex circuit is a key part of the product so will figure out how to test that in a lofi manner.

We've avoided local shops due to cost until now, but when put like that, we should consider them now. Yep we've been optimising to reduce reruns, but the time spent doing so + the lead time is super frustrating. Standard engineeri

Great idea! I've never soldered SMDs but can defo learn. We're getting are boards assembled rn because soldering LGA-12 package ICs by hand is unfeasible, and it seems pointless to pay the setup fee and not get the other component

Lol that's defo true - I'm driven to this thought as lead times are super frustrating!

I see, I'm also based in Europe (London) so hopefully shipping time ends up being similar!

Interesting I see. I'm moving from breadboarding to PCBs because I'm using ICs which are way too small to solder by hand and I've already prototyped with their off-the-shelf dev board versions.

PCB manufacturing. They said the assembly is just about to start and they'll be shipping day after tomorrow. I'm in London so will have to see how long shipping takes!

Using flexi pcbs with SMD parts on one side only - does that change your answer at all?

Hey! I’m an engineering student trying to build a wearable to help people with back pain, having struggled with it myself for 10 years. I really need some data on people’s experiences with back pain, so I’d be super grateful if you could fi

UPDATE: Due to the great response to this thread, I built a tool for back pain relief: https://chat.openai.com/g/g-N4KUPUUox-back-pain-ai Trained it on leading research papers and the suggested resources below. What dy

How did you figure out what worked, exercise wise?

Fascinating! I'm curious to pick you brain a little bit more, given your background - got 15 mins to chat briefly?

Did you have back pain before doing any of this?
22.
by RohKo 3y ago
Great to hear you've found things that work! How was the foot issue diagnosed? Who did you work with for that? How were the pinched nerves diagnosed? Where did you start with your routine? How did/does it fit into your life?

Nietzsche had that right - "I am walking a lot, through the forest, and having tremendous conversations with myself." Guess he forgot the bit about back pain though... Awesome to hear you've found that this works! How did you

Thank you!!!

by RohKo 3y ago
Wow that's curious!! What prompted that decision?

What did you start with? How did you decide?

by RohKo 3y ago
Wow interesting. Do you work anywhere else but at home?

I'm super curious about this concept. I watched All The Rage about Dr Sarno, who treats back pain with the same mind-body approach. Its fascinating that the results are so drastic for people who've been healed by the mind-body app

Why did you start doing this? (may sound like a dumb question but humour me)
