I've been interested in soft robotics for a long time. When I was working in the FX industry about 10 years ago I had a phone conversation with Barry Trimmer at Tufts' Biomimetic Technologies Lab. We talked about ways to use the many mold making and...
I got around to start writing a basic feature list and some pseudocode for the longabord, which will all be written in Arduino running on the Adafruit feather M0 with Bluefruit. I have uploaded the document to the files section but also want to go over...
I thought that maybe I would be able to get the servo controller code below 1kB, and enter this project into the contest. And even if I don't, hey, it's a great opportunity to learn about AVR's TWI peripheral, so why not. Thus, for the last week I had...
Last week, the Conservify team started their tenure at the SupplyFrame DesignLab Residency! This opportunity is something we've been looking forward to for several weeks and we're very excited. This first post is going to outline the current state of...
I talked about this several times but only on the side lines and I think I have to give this topic a bit more depth as its actually THE selling point of the whole project. I also want to talk about it because I made it a more extensive topic of my overview...
HardwareBased on my prototyping and testing, I designed and built a first prototype. This version used an ESP32 as the microcontroller and wireless connectivity, a LIS3DH accelerometer for impact sensing, and a AAA size lithium ion cylindrical cell for...
Week 3 summary: The Adafruit feather adalogger was set up and wired to the encoder and LED. This is what will be used to test the code and troubleshoot. The coding process was also started. Our code in short displays different RGB values when the encoder...
NOTE: This project log was originally posted on 07/27/2023 at 18:51 EDT, but due to a misunderstanding, it had to be deleted and remade. One key requirement for the Open Book has never changed: I want it to be portable. I mean, it has to be, right?...
OK, big turnout as always when we have our Adafruit friends stop by! I'm Dan, I'll be modding today as we welcome PT, Limor, Scott, Dan and Jeff from Adafruit to talk about both the ESP32-S2 and the new RP2040. Welcome Adafruit people! pt12:00 PMhi...
The code is running (but may still contain some bugs and leftover debugging/engineering lines), and control is via BLEusing theBluefruit Control Pad running on the iOS Bluefruit app. Here is the prototype Arduino code to run the EmotiGlass breadboard:...
Populating (or stuffing) circuit boards can be a messy process. It's fraught with high heat, chemicals and teeny tiny parts. What could go wrong? 😬 In this post, you’re learn how I assembled the first prototypes of the nRF9160 Feather. It's my...
When there's WiFi in the Amazon Pretty much every sensor deployment we've done has been to remote areas with little or no connectivity. It can take days to reach some locations, either off roading through unforgiving terrain, boating in over crocodile...
The first item in the collection that I started working on back in September 2017 was a hacked wedding dress. I had my heart set on creating some kind of color changing dress in this project and spent a few weeks trying on wedding dresses at thrift...
On the right hand side is displayed readings from the oscilloscope with red being the output trianglular wave which feeds into the varactor input of the radar module. The blue trace is the output from the radar, amplified by the 2 stage op amp. The signal...
I’m starting to plan for a development board for this touchscreen display, since there is a giant mess of wires on my current breadboard. I want this board to mount to the back of the display and provide the FPC connections to the Display and Touchcscreen...
