I love this. I&#x27;ve been a professional dev for almost a decade now, and over the last couple of years have started migrating toward a blend of hardware and software&#x2F;firmware development, and I can&#x27;t get enough of learning to build physical things from scratch. I don&#x27;t often get to iterate in this way at my job, and rebuild the same thing over and over, so I tend to spend my free time with projects like this that start out shitty, and you get to take the time to comb over the details, making constant prototypes.<p>I started a deep dive in electronic music and synthesizers in the last couple of months, and have been thoroughly enjoying playing the productions units I own (Korg Monologue, Elektron Digitakt, Roland JV1080), but have even more so enjoyed the sort of free form effort of building my own instrument:<p><a href="https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;FZ6GFsI" rel="nofollow">https:&#x2F;&#x2F;imgur.com&#x2F;a&#x2F;FZ6GFsI</a><p>That started out as a nightmare breadboarded voltage controlled oscillator, to a nicely breadboarded vco, to a rebuild on perf board, and then obviously I needed a perfboard power supply. But, once I wanted a mixer, I needed +&#x2F;- 12v, not just 5v, so that led to a better iteration of the power supply, etc. It&#x27;s a rabbit hole, but an immensely educational and fairly inexpensive one. I figure I&#x27;m about 3 months and a couple of YouTube tutorials away from my first Kicad developed oshpark printed PCB, and I have a ton of ideas for next steps, and prototypes in flight (CES3340 based VCO, Arduino MIDI control and CV translation, Lowpass&#x2F;bandmiss filters, so on and so forth).<p>Back to the subject of the original post, this totally looks like Pennsylvania, and if it is and the engineer who built this is in the job market, and has any interest in working for a smaller, established (20 year) shop that lives in one of the automotive spaces doing a lot of cool custom hardware&#x2F;software development, I&#x27;d happily accept a resume.

If you want to build a really cheap drone that can actually do autonomous GPS-guided stuff, the Kakute F7 can be flashed with Arducopter (Arudpilot), and is $49 with a power distribution board. Mostly intended for small racing drones, but can be used for other purposes.<p><a href="https:&#x2F;&#x2F;www.getfpv.com&#x2F;holybro-kakute-f7-aio-flight-controller.html" rel="nofollow">https:&#x2F;&#x2F;www.getfpv.com&#x2F;holybro-kakute-f7-aio-flight-controll...</a><p><a href="https:&#x2F;&#x2F;shop.holybro.com&#x2F;c&#x2F;kakute-f7_0486" rel="nofollow">https:&#x2F;&#x2F;shop.holybro.com&#x2F;c&#x2F;kakute-f7_0486</a><p>Or you can get the version that combines a four motor ESC in a stack with the version of the Kakute F7 that doesn&#x27;t have a built in PDB (power distribution board), for under $120.<p><a href="https:&#x2F;&#x2F;shop.holybro.com&#x2F;kakute-f7-amp-tekko32-f3-metal-4in1-esc-combo_p1129.html" rel="nofollow">https:&#x2F;&#x2F;shop.holybro.com&#x2F;kakute-f7-amp-tekko32-f3-metal-4in1...</a><p>other parts needed to complete something: motors, propellers, frame, battery, video tx (for something like 5.8 GHz band goggles), RC receiver, wiring, ublox m8n GPS receiver.<p>want a cheap frame? It&#x27;ll be heavier than ordering a $45 carbon fiber frame from banggood or gearbest or aliexpress or such, but you can 3d print one at the cost of maybe half of a spool of $18 PLA filament:<p><a href="https:&#x2F;&#x2F;www.thingiverse.com&#x2F;thing:261145" rel="nofollow">https:&#x2F;&#x2F;www.thingiverse.com&#x2F;thing:261145</a><p><a href="https:&#x2F;&#x2F;www.thingiverse.com&#x2F;thing:1206960" rel="nofollow">https:&#x2F;&#x2F;www.thingiverse.com&#x2F;thing:1206960</a>

I&#x27;ve only seen the word written as jank, janky or jankiest. First for jankest. Where can I view photos of the various physical build attempts?

For a minute I thought the drone algorithm was somehow running on Scratch, and I was curious as to how the author had managed to accomplish this feat...

Hi, I&#x27;m the creator! Thank you all for your thoughtful comments.<p>Some of you wanted a photo album of the journey; I quickly collected one here [0]. Apologies for duplicates, no descriptions, and Google.<p>The full album shows a lot more of the process, but I also linked some quick highlights &#x2F; milestones at the end of this comment.<p>Also, to those who were wondering, I am still in the market for a Summer 2019 internship.<p>I really ought to have a blog post detailing more of this, but here&#x27;s a little backstory anyway. My best friend from high school and I wanted to experiment with creating our own modular drones, and although we bought a bunch of parts, we ended up leaving for college before we could do anything. A couple years later I had some time on my hands, and I decided that I wanted to see whether or not I could actually build and program a drone myself. For the project, I tried to focus on writing high quality software while still managing to build something flyable with my nearly-nonexistent mechanical skills. Even though much of this project was physical (and electrical), I still largely consider this a software project, actually.<p>Physically, my prototypes are something you might laugh at. Zip ties, styrofoam, and Gorilla tape were my go-to materials for the most part. I originally started by mounting (read: zip-tying and taping) components to PVC tubes and metal sheets; combined with the pretty large LiPo battery I bought, it should have been no wonder that four motors were no match for the weight of the thing. I later decided to screw together 6 strips of carbon fiber sheet (a &quot;frame&quot;) and add two motors to help assure my drone can actually lift greater than two inches off the ground at a time. Reworking the flight controller to work with six motors instead of just two was a fun challenge; I decided to make the flight controller support an unlimited number of motors in a circle while I was at it.<p>Figuring out the optimal wireless technology for the drone was a bit of a process as well. It was frustrating when I thought I had everything ready for a test flight, but then slowly realized that, perhaps, I wasn&#x27;t going to be able to get away with using Bluetooth LE over non-trivial distances. Eventually I found a radio module with superb distance and transmission rate; and after some struggle, I got them working. You can see in the video that I could control the drone from quite far away!<p>It took quite a few days of test &quot;flights&quot; to get the drone to fly as well as it did in the video (if you consider the oscillating nightmare in the video &quot;flying well&quot;). Even getting the drone to launch two feet in the air, instantly lose control and backflip, and crash back down on the ground felt like an AMAZING feat from my perspective; it demonstrated all my systems were at least online and functional. I slowly increased the hover time of each attempt by a couple seconds or so, adjusting my controller tuning and implementation as I went. The flight in the video was nowhere near as primitive as some of my early experiments, even.<p>I&#x27;m sure I skimped on many details, don&#x27;t hesitate to ask for more information on anything.<p>[0]: Full album: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;QhSZEyd4DA1r9S9G6" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;QhSZEyd4DA1r9S9G6</a><p>First physical prototype: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;k6km6Hyrkq4FuxkH9" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;k6km6Hyrkq4FuxkH9</a><p>Second physical prototype: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;sL1LjnAgeXrmGvgEA" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;sL1LjnAgeXrmGvgEA</a><p>Third physical prototype: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;bY33peH7RZbXPxyx9" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;bY33peH7RZbXPxyx9</a><p>LED strip code testing: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;wZJJJ4NrFENjpUkHA" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;wZJJJ4NrFENjpUkHA</a><p>Custom remote control assembled: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;z577cVbH59vjW3g56" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;z577cVbH59vjW3g56</a><p>Final &quot;boxy&quot; physical prototype: <a href="https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;8ESsQidi5Tgsb1mm6" rel="nofollow">https:&#x2F;&#x2F;photos.app.goo.gl&#x2F;8ESsQidi5Tgsb1mm6</a>
