Seven builds drawn up properly, plus the people and the plan behind them: wiring, dimensions, parts lists with links, the drones I actually fly, robotics, the swim block, and the road to Exeter. Pick a sheet.
A · Low-ESR cap soldered right on the pads. Kills voltage spikes before they reach the gyro. B · O4 antenna clear of props and carbon. C · RX antennas at 90° to each other.
A · Cable glands or potted epoxy pass-throughs. This is where ROVs die. B · Bilge motors are already wet-rated. Grease the shafts anyway. C · Strain-relieve the tether to the frame, never to the electronics.
| Item | Spec | Qty |
|---|---|---|
| Frame | 1/2" PVC pipe + fittings | 1 |
| Thrusters | Bilge pump motors, 750-1100 GPH | 3 |
| Props | 40 MM press-fit | 3 |
| Drivers | BTS7960 H-bridge modules | 3 |
| Control | Arduino Nano + 2 thumb joysticks | 1 |
| Enclosure | Acrylic tube or dry box + glands | 1 |
| Tether | Cat5, 15 M, strain relief | 1 |
| Camera | Analog board cam + topside screen | 1 |
| Ballast | Washers, foam, zip ties | 1 |
A · Antispark loop key. Pull it before your fingers go anywhere near the belt. B · Belt tension: about 5 MM of give. Too tight kills bearings, too loose skips on braking. C · Set brakes soft in VESC Tool first. Grabby brakes throw you forward.
| Item | Spec | Qty |
|---|---|---|
| Deck | 38-40", stiff | 1 |
| Trucks + wheels | RKP trucks, 90 MM wheels | 1 |
| Motor | 6374 outrunner, 190KV | 1 |
| Mount + drive | Motor mount, pulleys, HTD-5M belt | 1 |
| ESC | VESC 6-based, single drive | 1 |
| Battery | 2× 5S 5000 mAh in series (10S) | 1 |
| Remote | 2.4G thumb remote | 1 |
| Misc | Loop key, enclosure, 10AWG, grip | 1 |
A · FPV bay sized for an O4 unit out of the quad bin. Maiden without it. B · Low rates for the maiden: small throws, ~30% expo. C · A spare 2207 quad motor flies this fine on 4S with a 6×4.
A · The crossed top run is what makes CoreXY work: motors together = X, motors opposed = Y. B · Pen sits on the belt centerline or your circles come out oval. C · Tension both belts evenly, like two guitar strings tuned to the same note.
A · Parallel linkage keeps the gripper level without an extra wrist servo. Free elegance. B · Servos brown out an Arduino's 5V pin. Power them from the 6A supply with a common ground. C · Center every servo to 90° before screwing horns on. Saves a full teardown later.
A · Headworks and manifold live at the barn hydrant, everything downstream is low pressure. B · One lateral per veg row, all fed off V1. C · Each tree gets its own loop, six loops on V2.
D · Backflow preventer goes first. It keeps zone water out of the well your grandparents drink from. E · Filter before regulator: grit is what kills emitters. F · 3/4" 24VAC solenoid valves, one per zone.
G · Transformer plugs into the barn outlet; only safe 24VAC leaves the box. H · ESP32 runs the schedule over WiFi, phone control from the house. If Uncle vetoes the DIY board, a store timer wires up the same way. J · Every solenoid shares one common return wire.
K · Emitter sits at the root zone, not on the leaves. Punch the lateral, barb in, done. L · Trees get a loop with two emitters so roots grow even on both sides. M · Fold the line back in a figure-8 end. Pop it open each spring to flush.

Ideas parked here until a bench opens up. No BOMs yet, just intent. Promote one to a numbered sheet when it earns it.
One lift motor, one thrust motor, a skirt cut from a trash bag. Dumb fun and a real intro to thrust vectoring.
GPS + LoRa payload under a weather balloon. Near-space photos. FAA Part 101 rules on payload weight apply, read them first.
18 servos, 6 legs, inverse kinematics. The robot arm (WE-006) is the warmup for this.
Hand-wired switches on a Pi Pico running KMK. One-key shortcuts for Betaflight CLI and OBS.
3D printed blades, stepper motor as generator, log the output. Science-fair energy but with real data.
Foam hull, one 2207 on a flex shaft, ELRS receiver from the parts bin. Costs almost nothing.
Addressable LED strip on a quad, long-exposure camera on a tripod, patterns in the night sky.
1:10 rock crawler, printed chassis and links, brushed motor. Suspension geometry is the actual lesson.
The big one. QS hub motor, 72V pack, real frame, real brakes. Every sheet above this line is practice: motors, batteries, VESCs, wiring discipline. When the skills stack up, this gets a drawing number.
A · President is the other elected seat, top of the ticket. B · Vice President, my seat. I run the day to day of student government: assemblies, spirit weeks, and getting the grade’s priorities in front of faculty. C · Assemblies, spirit, and faculty relations all run through this office.
| Op | What I Do | Cadence | Status |
|---|---|---|---|
| Morning assembly | Lead the run of show | Weekly | Running |
| Spirit week | Own it end to end | Seasonal | Legendary |
| Grade advocacy | Take priorities to faculty | Ongoing | Active |
| 8th v faculty game | Organizing the matchup | Annual | In the works |
| Graduation | On the planning crew | June | Shipped |
A · Doubles Tuesday and Thursday: mornings are technique and starts, afternoons are the main sets. B · Sunday is off, and it’s on the plan, not a skip. C · Race pace loads toward the end of the week so meets feel like the easy part.
| Event | Where It Sits | Course | Goal |
|---|---|---|---|
| 100 Breast | Main event | SCY | Keep dropping time |
| 50 Breast | Sprint | SCY | Faster every meet |
| 50 Fly | In the mix | SCY | Back on the podium |
| Freestyle | Building it up | SCY | 50 + 100 pace |
A · The robot starts and returns to base. Every run begins and ends here. B · Mission models sit around the mat, each one worth points if the robot completes it. C · The dotted line is one route through the missions. Program it, test it, tighten it, repeat.

|---|---|---|---|
| FIRST LEGO League | Town School | LEGO robot | Where it starts |
| VERTEX FTC | Exeter | Full FTC bot | Trying out |
| MUREX ROV | Exeter | Underwater ROV | Trying out |
The build on this sheet is a 7-inch FPV quad, put together from the frame up: solder the stack, mount the motors, tune it in Betaflight, then fly it until something breaks and fix that too. Every photo here is a real build.
NEXT · I’m not stopping at quads. I want to build a lot more, and I’ve already started researching an underwater ROV to try out for MUREX at Exeter.

I’ve got my Pleasure Craft Operator Card, so I run my own boat up in Canada. It’s a Lund 14 Rebel, and I take it out for walleye all summer. That’s my cousin in a lot of these. We fish the lake together whenever I’m up there.
| System | Detail | Note |
|---|---|---|
| Hull | Lund 14 Rebel, aluminum | Fishing boat |
| Power | Mercury outboard | Runs the lake |
| Electronics | Fish finder and sonar | On board |
| Rig | Rods, net, tackle box | Walleye setup |
| License | Pleasure Craft Operator Card | Canada |
This is the one that means the most to me. I’ve been up on skis behind a boat for as long as I can remember, first on two, then slalom on one, always chasing my cousin down the lake. He’s the reason I ski. I watched him make it look easy, wanted to be him, and kept at it until I could hang. Some summers it’s Canada, some it’s France. Different water, same feeling the second the rope goes tight.
| Water | What It Is |
|---|---|
| Canada | The family lake. Cottage, dock, glass-flat mornings. Where I learned, right behind my cousin. |
| France | Skiing abroad. New lake, same rope, same reason I’m out there. |
I’ve looked up to my cousin my whole life. On the water he set the bar, made it look effortless, and I wanted that more than anything. Every set behind the boat I’m still chasing him, and honestly that’s half the reason I love it. That part has never changed.
Tigers
San Francisco · Est. 1939
Town School for Boys is my old middle school, K-8 in Pacific Heights, San Francisco, founded in 1939. I’m at Exeter now, but this is where it started. I was Student Body Vice President here, and I was on the A basketball, cross country, and track teams. The tagline still fits: agile learners, creative thinkers, leaders for good.
Town runs on five core values, and they’re in everything from the classroom to the court.
| Value | What It Means Here |
|---|---|
| Joy | Love of school is the whole point |
| Integrity | Do it right when nobody’s watching |
| Curiosity | Ask, build, take the thing apart |
| Respect | For yourself and everyone else |
| Belonging | Every kind of boy has a place |
| Count | What |
|---|---|
| 1 : 6 | Teacher to student ratio |
| 6 | Upper School robotics teams |
| 30+ | Basketball teams, a team for every boy |
| 20 | Student-led clubs |
| 125+ | Mathletes, grades 3-8 |
| 2 + 1 | Rooftop fields and a rooftop garden |
| 35,000+ | Books checked out last year |
None of this happens on my own. A few teachers at Town pushed me, believed me, and got me to where I am, and I owe them for it.
| Teacher | Thank You |
|---|---|
| Mr. Tetenbaum | English. Taught me to write like I mean it and cut the fluff. |
| Mr. Wyatt | For the standard, and for expecting me to meet it. |
| Mr. Berryman | For the push when I needed it and the patience when I didn’t know it yet. |
| Mr. Wild | For making the hard stuff make sense. |
| Mr. Kendal | For backing me the whole way through. |
And to Archer and Willy, for all of it. Thank you.
Non Sibi
not for oneself
This is where I’m headed for 9th grade. Phillips Exeter Academy, founded in 1781, is one of the oldest boarding schools in the country. About 1,100 students in grades 9 through 12 from all over the US and 30-plus countries, living and learning on a 700-acre campus in New Hampshire.
A · The teacher sits at the table, not in front of it. B · Twelve students, one discussion, every voice equal. You come ready, you talk it out, you learn from each other. This is how every class runs at Exeter.
Harkness started at Exeter in 1930 with a gift from Edward Harkness. No lectures, no rows of desks. Twelve students and one teacher work through the material together around an oval table. It is not about being right, it is about thinking out loud, listening, and building on each other. At Exeter it runs in every subject, and it is the whole reason I want to be there.
Exeter’s mission is to unite goodness and knowledge and inspire youth from every quarter to lead purposeful lives. Three mottoes are carved into the seal.
| Motto | Meaning | Language |
|---|---|---|
| Non Sibi | Not for oneself. What you learn is for others too. | Latin |
| Finis Origine Pendet | The end depends on the beginning. | Latin |
| Charite Theou | By the grace of God. | Greek |
| Item | Detail | Note |
|---|---|---|
| Courses | 450+ across 18 subject areas | Most of any US boarding school |
| AP classes | None. Courses go beyond AP level | College pace |
| Calendar | Trimesters, class 8am to 6pm | Some Saturdays |
| Ratio | 5 students to 1 teacher | Small tables |
| Library | Largest high school library in the world | Designed by Louis Kahn |
| Admission | Need-blind, free tuition under $125k income | Youth from every quarter |
Exeter’s Robotics Club runs several FIRST Tech Challenge teams out of the Design and Innovation Lab. VERTEX is the flagship, and it won the FIRST Tech Challenge New Hampshire Championship and earned a spot at the World Championship in Houston. There’s also MUREX, the underwater ROV team. I’m trying out for both.
| Team | What It Is | Me |
|---|---|---|
| VERTEX | FTC 15534, the flagship, NH champs to Worlds | Trying out |
| EDGE / SURFACE / APEX | The club’s other FTC teams | On my radar |
| MUREX | Underwater ROV team | Trying out |
| Design & Innovation Lab | Maker space: 3D printers, laser cutter | Where I’ll build |
Big Red swims in the Roger A. Nekton Championship Pool in Love Gym, one of the best facilities in New England: 8 lanes, 25 yards, full Colorado timing, two diving boards, an anti-wave surge tank, and seating for around 800. The program has been nationally ranked since 1994. New pool, new team, same events.
Where I’ll train. Past the pool, Exeter athletics run out of the Thompson Field House and the gym: indoor track, turf fields, a full strength center, and courts under the lion.
| Line | Status | Note |
|---|---|---|
| Work ethic | Carries over | Non-negotiable |
| Swimming | Continues | Club, then team |
| FPV builds | Continues | New shop |
| Leadership | Reset | Earn the room |
| Willy | Coming too | Town boy |
Everything in this set is mine: the builds, the farm system I’m putting in with my cousin and uncle, the student government, the swim block, the road to Exeter. If it’s on a sheet, I either built it or I’m building it.

I’m an 8th grader at Town School in San Francisco, and next year I’m headed to Phillips Exeter Academy for 9th grade. That move is a big one. Town has been my whole world for years, and I’m about to drop into a new place across the country where nobody knows me yet. I’m ready for it.
What I care about most is the work. I like locking in on something hard and grinding until it clicks, whether that’s a swim set I can’t hold pace on, a factoring problem that won’t come out clean, or a quad that won’t arm. None of it works the first time, and that’s the part I like. You figure out the pieces, you try it, it breaks, you fix it, and eventually it flies.
I build the same way I put this set together: figure out the parts, draw it up, then actually make it. Not a mockup, not a maybe, the real thing. And if a line’s wrong, I’d rather redraw it than fake it. That goes for drones, for school, for all of it.
