SwarmDrive Haptic Feedback Experiments

This time I would like to dive into the exciting domain of haptic feedback using electric motors. The result of it all is a resemblance of a mechanical rotary encoder where you feel the clicks. Read the full update.

Example SwarmDrive Firmware for BLDC Motor Commutation: Part II + Campaign Extension and Lower Price!

I would like to share with you that we have decided to extend the campaign for two more weeks. as an extra incentive we decided to lower the price of SwarmDrive to $59!! Also, last week in part I of Example SwarmDrive Firmware for BLDC Motor Commutation we covered the setup of the Space Vector LUT and obtaining the motor characteristics. In this second part we will look at the actual commutation code. Read the full update.

Swarmdrive Using The AS5048B Rotary Encoder

Good news from PCBWay, the two pre-production boards with the new silkscreen layer are on its way. Hopefully next week I can share some images. In the meantime, let’s have a look at the AS5048 rotary encoder, one of many choices for having a closed loop BLDC motor implementation. Read the full update.

Swarmdrive Remote Control Tutorial, and New Silkscreen

This week I would like to show how you could lay the foundation for remote control of a SwarmDrive with the onboard ESP32, and, while awaiting the outcome of this campaign with excitement, I decided to start a small preliminary production run. This is needed to verify a few minor changes, one of them being the addition of the SwarmDrive logo to the silkscreen, but also some minor adjustments of some tracks. Read the full update.

Launch Announcement!

First of all, thank you for your interest in SwarmDrive. I hope it will enable you to enter the fascinating world of BLDC motors what I like to call "The Easy Way". For me it did! As you might have read on the SwarmDrive website, I started this project because I felt that there should be a better way to get going with this interesting technology. Read the full update.
