📖 News that You Might Wanna Know️


01 Collaboration of Stanford University x Seeed: Open Source Haptic Device for Affordable Haptics Education for All

In 2012, Prof. Allison Okamura from the School of Mechanical Engineering, and Prof. Paulo Blikstein from the School of Education at Stanford University came together to devise upgraded educational haptic paddles used for teaching system dynamics, control theory, and mechatronics concepts. As a result, they created a DIY electronic kit called “#Hapkit” for on-campus courses, online courses, and educational research. For this Project, Seeed designed and made an all-in-one controller board called “Hapkit Board” to reduce the costs on microcontrollers and amplifications that support the Hapkit. 📖Read more details about the collaboration HERE.

02 Learn TinyML using Wio Terminal and Arduino IDE #6 Speech recognition on MCU – Speech-to-Intent by Dmitry Maslov 

A traditional approach to using speech for device control/user request fulfillment is first, to transcribe the speech to text and then parse the text to the commands/queries in suitable format. A more efficient way is to directly parse user utterances into actionable output in form of intent/slots. In this article I will share techniques to train a specific domain speech-to-intent model and deploy it to Wio Terminal. Here you can check the tutorial.

#Notes at the end.

If you’re new to this session, here is a brief intro to it. We have gotten dozens of requests over the years for a Seeed Monthly Newsletter. Although we already have a newsletter for weekly updates, we still need a place to host overall information about what’s happened on a monthly basis. It can offer an efficient and friendly way to get updated for the whole community. And that’s what we expect for our Seeed Monthly Wrap-ups. Instead of putting it a subscribe-to-read, we’re publishing them on our blog, keeping it as open and accessible as possible for the whole community. For each entry, we will cover awesome projects from the community, campaigns that we are running, new products, IIoT Solutions and even secret recipes of prototyping and manufacturing.
