I met up with [Kenji Larsen] at HOPE X last weekend, and I’m fairly certain he was the coolest person at a conference full of really cool people. Talking to him for a little bit, you get a sense of what it would be like to speak with [Buckmister Fuller], [Tesla], or any of the other ‘underappreciated, but not by people in the know’ minds scattered about history. I’ll just let his answers to our hacker bio questions demonstrate that.
[Kenji]‘s project for The Hackaday Prize is the Reactron Overdrive. It’s not just one board he’s building here, but an entire suite of sensors, interfaces, and nodes that form a complete human to machines – note the plural ‘machines’ – interface. When you consider that no one knows what the Internet of Things actually is, and that [Kenji] is working on IoT 3.0, you get a sense that there’s really something here. Also, his project log has a Tron Recognizer in it. That has to count for something, right?
Culinary arts, both sides of it. I love to make food, and love to consume it; I just really appreciate how diverse it can get. Lots of schools of thought, from French and Italian standards, to Japanese nature harmony, to chem-technical, to Ayurvedic, and many other things in between, and outside those concepts. I’ve eaten a lot of weird things. Even when it’s awful, I am glad for the experience. I took some courses at the Culinary Institute of America, and I like to tell people “I learned my knife skills at the CIA.”
Other hobbies are hiking, flying airplanes, and sailing, but I find I don’t have a lot of time to do these that much anymore. Have to eat, though…
Data analysis and prototyping for product and process development. I would characterize it as hacking, actually. There is a fair amount of metrology, experimentation and testing, visualization, simulation, and a lot of coding. There is a lot of time and workflow analysis. I analyze what can be done asynchronously, and what things must be done in critical path; what can be left open-loop, what must be done with feedback. There is usually a “critical now” period in every process that is supported by several non-linear, asynchronous worker processes. This got me thinking that really, human existence is the real “critical now” and we should use technology and just-in-time manufacturing methods, with the same non-linear optimization to augment that existence. Human experience is not just something we have by virtue of being alive – it is also something we are in charge of, can improve, optimize, and really is our most important product. That thinking led me to trying to do this with my own life’s workflow, and later led to my entry in The Hackaday Prize.
Violins and antique violin restoration. Here is a machine (and work of art) that is old enough to have a real natural evolution. Made of several different woods, animal substances, plant extracts, minerals, and insect secretions, this thing is the definition of hacking diverse stuff around you for optimum output. End result beauty. The older ones need some help to continue their beautiful existence. Restoration is not just repair – it’s harder in a lot of ways, because you must respect the flaws and exceptional excellences of what came before, remain true to the personality you found. It’s not just about bringing the machine back to some standard. I mean, that is part of it, but there is more to it. Maybe this is my passion because there are things about this that I cannot yet quantify (despite a lot of efforts!)
Cable box. So many reasons. But in reality it’s not something I would ever do. Poor defenseless components are better upcycled into awesome machines.
No operating system is the best operating system. Simple loop execution such as in the AVR allows you to optimize as you like. I totally get the utility of OSs in the sense of drivers and so forth, but uCs do that well enough with libraries. I find that once a system has a name, and is itself a product looking for market share, it feature creeps to serve many varying needs, until there is stuff I don’t want or need. Then it creeps further until that stuff is not removable. Wait, isn’t that the definition of cancer?
If you really press me, I will say Minix.
Well this is another tough question because I have several benches, all different. In my prototyping work, I have separate benches for electronics work, woodworking, inspection/measurement, microscopy, vacuum, high voltage, and sewing (yes, for wearables). There’s also a photography area but let’s not call that a “bench”.
I love my o-scopes but they are not the best ones out there, and I love my soldering irons but also, they aren’t anything too special. I love using my optical flat but don’t need to use it very often. I do use my granite surface plate all the time, but it’s just a flat rock. And of course my Fluke 79 DMM, but as much as I love it, it is unremarkable.
The one tool I use at all my stations is something I make myself, out of necessity. It is the pointy stick. You know those fiberglass rods they sell for next to nothing for marking the end of your driveway, so that they stay visible after it snows a lot? I cut them down to 10 inch lengths and sharpen the ends on the grinder at different angles, then hone them further with finer grits.
They are strong and durable, they are chemical resistant, heat-resistant, electrically non-conductive, great for high voltage. They can hold a fairly precise point, with which to

manipulate anything you need. From pushing around carbon fiber cloth in resin, to holding something you are machining on the CNC, to moving something you are looking at under the microscope, or holding something tiny down when you are soldering, or pushing textiles through a sewing machine when you are working on something small, these are totally versatile. I have several colors so that if I need several in a single job, I can keep them straight, if they need to touch different chemicals or whatever. I also grade the point angle by color, so I know what I am reaching for (asynchronous process, sight and recognition) before I obtain it – keeps the workflow utilization up.
Does the Earth’s crust count? (42.) If we are talking about a semiconductor design, it is very tough, there are so many. I have to say I do really appreciate the INA128/129 instrumentation amplifier. I mean I love the ATMega328P but that’s a higher level thing, more complex, and doesn’t need me to get it more press and admiration. The INA128/129 is simple, clean, and does for ADCs what the electron microscope does for the eye. Power in, high-resolution knowledge out, I like it.
C++. I think it is the best compromise of a lot of factors. Been that way for a lot of years. I will accept a better compromise, but so far haven’t seen one. I don’t like languages that attempt to make things easy for you by doing things for you in undocumented ways under the hood. It’s usually at the cost of performance, and loss of control over the process. I like manipulating memory directly.
This is not an easy question, because I am constantly re-prioritizing and I figure, anything that falls off the bottom by the time I die was not important enough to get to. That said, the top items right now are:
- Extend the time from now until I die (and stabilize bio-age at a good spot). Aubrey de Grey, hello! Help him, please – everyone help him if you can. I am trying to figure out how I can help. So I guess the top item is, the “How can I help Aubrey de Grey?” Project. (If this one works, I will get to complete more projects.) Maybe just writing this is helping by raising awareness. Here is a TED talk. Look, I am working on this project already!
- Build a practical anti-neutronic fusion reactor. People seem to be focused on Boron 11 at this time, but I have some ideas about Lithium 7 which has a good cross-section and seems just as promising. Lots of people have built fusors for regular deuterium reactions, so it’s not fantasy – but they are not over-unity yet. It seems like it may just be a matter of time before the right balance of things is achieved. I think Polywell technology is cool and I would just love to have some time to investigate it further. Fusion@home. Open source. I am sure someone will get to this before me, and that will take it off the list (or at least move it way down) because then it just becomes a formula – for me the discovery and experimentation process is the fun part – you know, the hacking.
- Engineered organs, like a seven-pump distributed heart (like RAID for blood flow). But people are doing this sort of thing now, and will likely get to it before I will. I’m cool with that, you go, people! Take the whole liver situation. We have to do better than transplants from corpses, or half-organ donations. The liver is one organ we know can regenerate parts on its own! 3D printing, extracellular matrix + stem cells, it sounds like an there is an exploit, let’s hack it. This would be #2 on my list if I felt I knew I could contribute enough – and really, it’s part of #1. But from what I have read, this is well on its way without me. Which is good, because then I will be able to focus on biological robots of arbitrary form. Bishop to King 7. Checkmate, I think.
Request buffering. That actually boils down to old-world etiquette, which, far from being an archaic system, simply defined rules of engagement, a standardized people interface. The style may change, but the concept is valuable. In modern speak, I try to be polite, and optimize my communication in harmony with the surrounding people and events. Human communication is like an RF mesh network. You need an organizing principle to maximize data transfer to all nodes. (Thanks for listening.)
It is the one I live and breathe.
Computers are tools. They need to be useful, or step aside (or be upcycled into excellence). They are sophisticated enough now to know when they need extra time to prepare for a task, or when they are failing. Those things need to be removed from the critical path of human activity, otherwise we are just going to spend our precious moments being maintainers of machines. Forget that. When I was younger, one statistic often cited was how many years of our lives the average person would spend in their car commuting. Now many work from home, and the time taxes are smaller and distributed. Waiting for machines to boot, to log in, web pages to refresh, “please wait while your updates are being installed”. Really? Add them up, do the math. It is worse than dying that much earlier, since you have to sit through it all. I joke (sort of) that I am trying to make computers “go away” – that seems surprising to some people because I’ve been working with computers my whole life, and my solution to make them go away actually means having many, many more of them. But my project is about freedom of experience, and there are also aspects pertaining to personal data ownership. It’s definitely in the spirit of the Hackaday Prize; when I read the bit about technology giving individuals the freedom to build the future, where once only large corporations could do something meaningful, I thought, yes, I will do this.
I am often really jammed for time, so I started to use my manufacturing process knowledge to optimize it. It has worked in some ways so far, and I am looking to expand its scope. I’m still as busy as ever, so it is hard to get this stuff documented, but making this a formal entry has forced me to be a bit more rigorous. I think it could benefit a lot of people..
Right now the thing that I would like to have help on is how to get reasonable integration with multiple Kinects, native on Debian. Short term-goal obviously, but seems like a great sensor and integrable into my paradigm. I’m sure it will be superseded soon by something 10X cheaper and 100X more awesome, but for now, this is what we have.
Sure, see my list above, any of them, but for this Prize the fusor is probably the most appropriate. I wouldn’t tackle it for the Prize because of the timeframe. But if anyone is bold enough to go for it, I will gladly contribute! Maybe engineered organs is closer to practical already though. Again, I will help if I can!
Just need time to think!
I’d like to explain my avatar.
It’s a symbol related to the Schrödinger wave equation, applied to human and machine interfaces, instead of matter. We expose our abilities and properties, what we are about, through our communication and cooperation. These interfaces can be harmonic, or vibrationally destructive, which consumes energy. That’s the same for matter, people, or computers. One curve represents machine interfaces, and the other human interfaces. The two together look like a double helix, a good metaphor for what I am trying to do with my THP entry.
