Keenan Johnson @keenanjohnson.com · 26/09/2026I guess I am in the target demographic since I worked at space x a long time ago but eeesh these ads scream of desperation. 000
Keenan Johnson @keenanjohnson.com · 26/09/2026If I have to see one more of the most cringy grok bot ads on the internet I will flip. 100
Keenan Johnson @keenanjohnson.com · 25/09/2026Overheard walking outside: “I am trying to pivot my career, so I asked an AI. Truly it just made my confusion even worse brah.” 010
Keenan Johnson @keenanjohnson.com · 24/09/2026Oh weird. Never had that happen before with oshpark. Do you have a reflow oven or will you attempt the hand solder? 100
Keenan Johnson @keenanjohnson.com · 24/09/2026My main premise is that most engineering teams don’t actually want to be good, but some do and I love helping them. I do a lot of coaching / mentoring / consulting on that and I love it. If I was better at marketing myself maybe I could just do speaking / do that full time. 020
Keenan Johnson @keenanjohnson.com · 21/09/2026One day I hope that I'll be able to just work on whatever I want and create things that are useful or needed, but would never get built because capitalism. 050
Keenan Johnson @keenanjohnson.com · 21/09/2026Had a meeting today where someone validated and then talked about the next steps for an idea I've been working on for over five years. It's taken a long time to find the right fit, but some ideas just take that long. 030
Keenan Johnson @keenanjohnson.com · 21/09/2026So many really good technology people just spend all their time shooting down ideas rather than trying to reframe them into something that is feasible or useful. 010
Keenan Johnson @keenanjohnson.com · 21/09/2026Being a non delusional, optimistic technologist is one of the hardest things, but if you can walk the line, then you will do amazing things. 130

Keenan Johnson @keenanjohnson.com · 19/09/2026It's not real cad if yu don't spend time spinning it around. This board is a bit goody as it uses huge connectors to ensure it can be hand soldered and is very high current. 151
Keenan Johnson @keenanjohnson.com · 19/09/2026Also fits the "dull, dirty, dangerous" idea of where robots are most useful as spending hours underwater in the deep ocean counting kelp is certainly dull, dirty, and dangerous. 010
Keenan Johnson @keenanjohnson.com · 19/09/2026This work is typically done with scuba divers visually, but given the scale of the ocean and the immersive amount of conservation work ahead of us, it is impractical to achieve our goals with scuba divers alone. 110
Keenan Johnson @keenanjohnson.com · 19/09/2026Essentially yeah. More specifically trying to locate and count things like kelp, invertebrates, and fish, which are the foundations of the ocean eco systems. 110
Keenan Johnson @keenanjohnson.com · 19/09/2026This press release I linked yesterday is also really good high level context: www.seattleaquarium.org/press-releas...seattleaquarium.orgNew Partnership Paves the Way for Reintroducing Sea Otters to Oregon - Seattle AquariumThe Seattle Aquarium, Oregon Coast Aquarium, Elakha Alliance and Wildlife Conservation Network’s (WCN) Sea Otter Fund are collaborating to generate new data on how sea otters—or their absence—affects ... 110
Keenan Johnson @keenanjohnson.com · 19/09/2026Totes. This repo is probably the best place to start with some basic context / videos. Feel free to drop any questions and happy to answer though. github.com/Seattle-Aqua...github.comGitHub - Seattle-Aquarium/Coastal_Climate_Resilience: This is a public repository to organize information and documents pertaining to the development and testing of the Seattle Aquarium's BlueROV2This is a public repository to organize information and documents pertaining to the development and testing of the Seattle Aquarium's BlueROV2 - Seattle-Aquarium/Coastal_Climate_Resilience 110
Keenan Johnson @keenanjohnson.com · 19/09/2026Sending a new PCB for sea otter conservation robot out to fab today. So fulfilling to do great engineering for good causes. 150
Keenan Johnson @keenanjohnson.com · 19/09/2026Of all the things I could not have predicted this year, seeing T-Pain become a dad cave, basement lair 3d printing enthusiast is at the top of that list 042
Keenan Johnson @keenanjohnson.com · 19/09/2026Wow so many likes! If any people like the work, everything is in open source and you can see it here: github.com/Seattle-Aqua...github.comSeattle AquariumSeattle Aquarium has 18 repositories available. Follow their code on GitHub. 001
Keenan Johnson @keenanjohnson.com · 19/09/2026If I have learned anything today it’s that the internet likes sea otters, robots, and especially the combination thereof. 000
Keenan Johnson @keenanjohnson.com · 18/09/2026Wooot some of my work with the Seattle aquarium's robotics for Sea Otters is starting to get published: www.seattleaquarium.org/press-releas...seattleaquarium.orgNew Partnership Paves the Way for Reintroducing Sea Otters to Oregon - Seattle AquariumThe Seattle Aquarium, Oregon Coast Aquarium, Elakha Alliance and Wildlife Conservation Network’s (WCN) Sea Otter Fund are collaborating to generate new data on how sea otters—or their absence—affects ... 828831
Keenan Johnson @keenanjohnson.com · 18/09/2026I’ll be impressed with new software tools when this class of bug is fully solved and no one thinks of it anymore haha 010
Keenan Johnson @keenanjohnson.com · 18/09/2026Wishing all products I used came with such a concise and awesome info sheet like this: 001
Keenan Johnson @keenanjohnson.com · 18/09/2026Just heard someone say: "The internet, it's not all bad" 000
Keenan Johnson @keenanjohnson.com · 17/09/2026I have many opinions, but I will instead just leave this classic paper that I suggest everyone read before placing their own opinions in the comments: No Silver Bullet Essence and Accidents of Software Engineering by Frederick P. Brooks, Jr. www.cs.unc.edu/techreports/...cs.unc.edu 000
Keenan Johnson @keenanjohnson.com · 17/09/2026Been working on this nice little easy to hand solder pcb for the seattle aquarium in between other harder EE projects for secret clients. 020
Keenan Johnson @keenanjohnson.com · 16/09/2026Had to call a customer support. Got passed between three separate AI support bots which had to interact with in different ways (voice, numeric entry, and then voice again). They each had unique hold music. This is a new kind of support hell. 010
Keenan Johnson @keenanjohnson.com · 16/09/2026My main technical niche seems to now be helping out robotics and sensing teams that have raised a lot of money, built a prototype and have not a lot of ideas how to make it reliable next. 010
Keenan Johnson @keenanjohnson.com · 16/09/2026My goal for reference is I do a lot of consulting work for different technical / creative clients. My lifestyle is also somewhat transient for the next six months to a year or so, so instead of constantly traveling very far to my lab, I am wondering if I can just take my lab with me haha 010
Keenan Johnson @keenanjohnson.com · 16/09/2026I know a lot of people in the construction industry like this packout crates that can stack / unstack etc. I am currently thinking of something similiar. These are strong enough to protect a o-scope / some other somewhat fragile stuff and be easy enough to take around to client sites. etc 000
Keenan Johnson @keenanjohnson.com · 16/09/2026Thanks these are great for ideas! Here's a link on pifpack which is very cool: wsp.plusea.at/collection/c...wsp.plusea.atWSP 010
Keenan Johnson @keenanjohnson.com · 16/09/2026Yes definitely! I think Salae might still be the best in the cheap-ish market. 000
Keenan Johnson @keenanjohnson.com · 16/09/2026Is it possible to create something of a mobile electronics lab? With a o-scope, e-load, soldering stuff, power supply etc to bring around to client sites for board bring up etc? What’s the best way? 541
Keenan Johnson @keenanjohnson.com · 15/09/2026Was just notified by the burger place I sometimes get takeout from that my info was exposed in a data breach. 100
Keenan Johnson @keenanjohnson.com · 15/09/2026It has become very obvious that most engineering companies do not understand the difference between a prototype and a product, how to move between them, or really design either very well. 160
Keenan Johnson @keenanjohnson.com · 15/09/2026When I was little I wanted a grappling hook for my birthday. I did not receive a grappling hook. 000
