EDA and MCAD on Your Phone: Dictate the Hardware You Want to Build

You can design hardware from your phone by voice with Flux. Open Flux in the mobile browser, tap the microphone, and say what you want to build or change. Flux, an AI hardware engineer, does the electronics and mechanical work. You check the result in the schematic, PCB layout, and 3D views on your phone.

Much of hardware work happens away from the desk: on the factory floor, at a customer site, at the bench, between meetings. Until now, a phone was good for reading email about a design, not for changing it. Typing a requirement with five constraints on a phone keyboard takes minutes. Saying it takes thirty seconds.

Five moments to dictate a design from your phone

Right after the customer meeting

You leave a customer meeting with a new product idea and a page of requirements in your head. In the parking lot, you open Flux, tap the microphone in the new project prompt, and say:

"New project: a battery-powered vibration sensor for industrial pumps. Three-axis accelerometer, BLE, a coin cell that lasts two years, and an IP67 enclosure that bolts to the pump housing with two M5 screws."

The requirements go into the project while the details are fresh. The Flux agent starts on the parts, the schematic, and the enclosure, and you review its first pass from your phone.

On the floor at the contract manufacturer

The line is ready to build, and the contract manufacturer tells you that the regulator is out of stock. You open the project on your phone and say:

"U3 is out of stock. Find a replacement that is in stock, has the same footprint, and gives 3.3 volts at 1 amp or more. Update the BOM."

Flux finds the candidates and makes the change. You check the part in the info panel and the board in the 3D view before you leave the floor.

At a field install

At the customer site, the sensor housing does not fit the mounting rail. The rail holes are on a 50 millimeter pitch, not 40. You stand next to the rail and say:

"Change the mounting hole pitch to 50 millimeters on the board and in the enclosure. Keep the USB-C opening where it is."

Flux changes the board and the enclosure together. You rotate the 3D model with your finger to confirm the fit, and share the project with your team.

At the bench with your hands full

You hold two probes on the first prototype, and the 5 volt rail drops to 4.6 volts under load. Your phone leans against the power supply. Your hands stay on the probes, and you say:

"The 5 volt rail drops under load. Make the trace from the USB-C connector to the regulator 1 millimeter wide, and add a second 22 microfarad capacitor at the regulator output."

The screen stays on while you talk, so you can read the message before you send it.

Between meetings

A teammate asks you to review a change before the end of the day, and you have ten minutes between meetings. You read the agent's summary, look at the layout and the 3D model, and dictate your review:

"Move the antenna keep-out to the board edge. Then check that the enclosure wall above the antenna is 2 millimeters thick, with no metal inserts near it."

How it works

1. Open Flux. Go to flux.ai in the browser on your phone. There is nothing to install.
2. Start or open a project. Use the prompt box to start a new project, or open a project link from your team.
3. Tap the microphone and talk. Your words appear in the message box while you speak.
4. Stop and send. Flux cleans up the transcript in a few seconds. Read it, edit it if you want, and send it. To stop and send in one step, tap send while you talk.
5. Review the result. Switch between the schematic, the PCB layout, the 3D view, and the files with the tabs at the top of the screen.

Flux keeps your words

Speech is not text. People pause, repeat, and say "um." When you stop, Flux makes the smallest changes that make the message easy to read:

• It corrects transcription errors, grammar, punctuation, and capitalization.
• It keeps your part numbers, component names, values, and technical terms.
• It keeps your intent. A question stays a question, and a list stays a list.
• It adds your words to text that you already typed. Say "change 3.3 volts to 5 volts," and it changes only that in your draft.
• It knows the conversation. Say "do the second suggestion," and the message names the step that you mean.

Flux does not answer while it cleans up your message. The Flux agent answers after you send it.

Made for a small screen

• The chat, the editors, and the info panel each use the full width of the screen.
• When you tap a link to a part in the chat, Flux opens the editor tab that shows the part.
• In the 3D view, rotate, pan, and zoom with touch gestures. Tap the cube button to show the view cube, then tap a face of the cube to go to a standard view.
• Open the info panel to see the properties of the part that you selected.
• Tap the share button to invite a teammate or copy the link.

The complete device, from your phone

Flux is an AI hardware engineer. It designs the complete device: the requirements, the parts, the schematic, the board, the firmware, the enclosure and the mechanical parts, the wire harness, the simulations, and the manufacturing files. On your phone, you work in the same project as on your computer, and your team sees the same project.

Voice dictation also works on your computer. Click the microphone in the chat, or press Cmd+D on macOS or Ctrl+D on Windows and Linux. Press Space to stop, or Esc to cancel.
