Smartplant

Tomato seedling with two seed leaves and its first true leaves, seen from above in the pot in the grow box lid Dashboard for a tomato grow: live and timelapse camera views of the plant and the root chamber, the current grow phase, light, mist and fan settings, and charts of water level, light, fan and vaporizer CAD model of the grow box: a tall rounded box with a vented top and a front panel Exploded CAD view: vented lid, electronics section with the circuit board, the plant lid with its pot hole, and the water tank

A mist-fed grow box I designed and built: a printed enclosure, a custom circuit board, Raspberry Pi Pico firmware and a web dashboard with live cameras, grow phases and sensor history.

Wi-Fi water valve

The valve in its black printed enclosure, mounted on a wooden post in the garden with a hose attached The closed valve: two hose connectors on a black printed enclosure with a flat mounting plate The opened valve: a solenoid valve between two hose connectors, next to a black circuit board with a Wi-Fi module and a mains power supply CAD model of the opened enclosure from above: the solenoid valve in the middle, with the circuit board behind it holding the mains power supply and a Wemos D1 mini 3D render of the circuit board: a long black board with the mains power supply, a DC-DC converter, a MOSFET, resistors, two terminal blocks and a Wemos D1 mini plugged into pin sockets

A smart watering valve for outdoor use. It has its own circuit board with a built-in AC/DC supply, so it runs straight off 230 V, and Wi-Fi and Bluetooth. It is controlled from Home Assistant through ESPHome and has run without problems in the garden for two years.

Hydrogen wave function visualizer

Particle cloud of the n=3, l=2, m=1 orbital with four lobes, seen along the y axis The n=4, l=2, m=0 orbital cut open, with controls for the quantum numbers, particle count, radius, phi and theta

Renders hydrogen orbitals from the Schrödinger solutions. Pick n, l and m and see the probability density.

LumenPnP paste utility

Paste pads and possible fiducials of a keyboard PCB, loaded from its paste and mask gerbers The paste utility with gerbers loaded: a list of 139 placements with coordinates and paste area, above the job preview

A rewrite of the LumenPnP paste dispensing tool. Talks to the machine over Web Serial and uses OpenCV.js to locate pads from the camera feed.

Load cell board

The bare board: a long black PCB with an HX717 chip, two connectors for the load cells and one for the controller The board wired up on the dispensing head, next to the syringe and its stepper motor

A board I designed for my solder paste dispensing rig. The syringe hangs from two load cells, and an HX717 reads them and sends the force to the Klipper controller, so the rig can feel when the nozzle touches the board.
