Summary of BUILDING PENNY’S COMPUTER WATCH FROM INSPECTOR GADGET
This article details a DIY project by [Becky Stern] to recreate Penny's smart watch from *Inspector Gadget*. The build features voice activation for the phrase "come in, Brain!" and displays images of Brain on a TFT screen. Powered by an Arduino Nicla Voice board, the device is housed in a custom 3D-printed case with a modified band, utilizing flexible wire for internal connections.
Parts used in Penny's Computer Watch:
- Arduino Nicla Voice
- Rounded rectangle TFT display
- 3D printed watch case (created in Tinkercad)
- Modified watch band (from Printables)
- 30 AWG silicone-jacketed wire
When you help your bumbling Uncle Gadget with all kinds of missions, you definitely need a watch that can do it all. Penny’s video watch from Inspector Gadget has a ton of features including video communication with Brain and Chief Quimby, a laser, a magnet, a flashlight, a sonar signal, and much more.

To round out her Penny costume, [Becky Stern] has created a 3D printed version of Penny’s incredibly smart watch. It listens for Penny’s iconic phrase — come in, Brain! — and then loads a new picture of Brain on the rounded rectangle TFT display. Inside the watch is an Arduino Nicla Voice, which has to be one of the tinier machine learning-capable boards out there.
[Becky] created the watch case in Tinkercad and modified a watch band from Printables to fit her wrist. With such a small enclosure to work with, [Becky] ended up using that really flexible 30 AWG silicone-jacketed wire for all the fiddly connections between the Arduino and the screen.After getting it all wired up to test, she found that the screen was broken, either from pressing it into the enclosure, or having a too-close encounter with a helping hands. Let that be a lesson to you, and check out the build video after the break.
