Haha a friend of mine once deleted a key to his Ethereum wallet with more than a million bucks worth of Ethereum on it, due to mistake in his script. That is as "hurt" as it gets :D
Have you ever hurt yourself from your own code?

Not quite robotics, but some of our servers kept powercycling , had to plug in the physical terminal. It was close to lunch, so I kept eating. The finale was a jar of mayo spilled into the guts of a 50k server. Best mayo I ever had.
What kind of server room allows you to bring food?
I mean, there's a reason why pain is involved in this story.

#133Was trying to control a 2 ton weighting diesel generator from my code and a few relays.
Didn't go right.

#134About seven years ago I got a bright idea to build a quadcopter. I had experience with little $25-50 drones that bumped around the house with their fragile one-inch propellers, which obviously qualified me to build and pilot something significantly bigger. Off to Aliexpress and Banggood I went. I ordered a carbon-fiber chassis, big strong motors, ESCs, 3-inch propellers, a FrSky receiver, a Devention transmitter, an…
tl;dr: Experience makes dangerously careless. Examples: quadcopters, lasercutters. I had a similar scenario with the same preconditions. In this case, one of the propellers came off and barely missed a face. This was a 10 inch hard plastic prop with some sharp edges. It could've taken an eye out. It could've caused serious cuts. It could've been a carbon fiber prop and caused _serious_ cuts. Of course it could also h…
I stick with off-the-shelf drones since my DIY incident, but I still get very uncomfortable when mine hover at eye level.

I used to do robotics, I can tell you that the fact that it was the cheapest or the most hacky does not matter in the least. Everything can and will go wrong, even the priciest and well documented part. I used to have multiple clamps around the controller, message bus, the firmware and also a physical barrier, and yet would not feel safe with my fingers or person around moving parts.

Is mayo mayonnaise? Do people eat mayonnaise by jars?

#136I think the dumbest way I could have hurt myself was trying to build a DIY laser cutter with a 2W IR laser. The catch is that you don't know wether it's on or not. As they say in the laser community "Don't look into the laser with your remaining eye".
The most consistently hurting project was a plotter that printed images with milk (don't ask why), it used a heating part to reveal the drawing. When a paper jam creates a fire you sure want to be near during a print job ! Plus burning my fingers a few times (lost some parts of my fingerprint on one of my thumbs).

tl;dr - too much modafinil. Yes, I have Crohn's and I do not like to take the meds or listen to the doctors. This is NOT AT ALL SOMETHING I RECOMMEND, PLEASE DO NOT ATTEMPT IT. Crohn's is an auto-immune disease and the main class of drugs that is used to treat Crohn's like mine (long term) are called TNF inhibitors or TNF blockers. TNF alpha triggers the production of several immune system molecules, including interl…
600mg of modafinil will make you... really wired, right? Did you notice that you were super productive that month?

Yes, it is one of the therapies I am currently studying as I have had success with it but it does not scale. The reason I want to do this is so that I can create a Medicare/Medicaid E2E single payer solution that provides these solutions to everyone. Even people on the lower socioeconomic rungs. The pandemic was really hard for me and I have been behaving very recklessly in terms of my own health but I have been very…
As someone with autoimmune issues who rarely checks HN but is very interested in your work, do you have a newsletter I could sign up for or an email address I could reach out to to receive updates on your work?
Yes, I also am dying to just talk to anyone about my work and what I am trying to do. I am very approachable and I CRAVE the most vicious, critical feedback that I can find. You can email me (email on profile) as the newsletter stuff will not be done for at least 1 month.

#140A lot of times...
Skin/eyes: experimenting with high-brightness LEDs. These can become pretty hot in no-time. I was trying to do my own LED driver (regulating a PWM signal from voltage/current sensing), on an LED without heatsink. Because of buggy code, it started to burn my table, and by reflex I tried to pull it up with my hand....
Not to mention the countless times a white spot remained in my vision for hours, after looking at such bright LEDs (buggy PWM signal regulation algorithm that kept going from dim to super bright randomly).
Ears: every time I write a driver for an amplifier/DAC with headphones output. No matter how many precautions I take. It is going to happen anyway (wrong register configuration, the default volume was too loud, etc.).
Also while listening to mic recordings done with a buggy/incomplete software.
