The Start Our DC25 project started immediately after DC24. On the car ride home we started brainstorming bigger and better ideas for the badge. Many were rejected but after the response we got with our first badge, we were motivated to do the next time....
A quick update with lots of progress designing the spectrometer (and thermal camera) board, attaching the radiation sensor board, and beginning to work on the low-level routines for the user interface!Fast and Efficient Bitmap RenderingNow that much...
It all started 4 years before, when I just got to know about the Raspberry Pi. It was still in the prototyping stage, a HDMI stick-like device back then, just like numerous Linux-capable HDMI dongles we can see now. It occured to me that it's wonderful...
I've been feverishly pulling the pieces back together!New fuses arrived - nice 10A fast-blow fuses, which are small and take up no real space due to the inline fuse holder. Together with some better continuous duty 36v relays, I've got a better power...
I know it's been quiet in this corner for a long time. But lately there have been some exciting things happening to this project. So here goes! ---------- more ---------- First of all, the most exciting news: I found a cable that fits...
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...
For reading and sending data will require two components: an Arduino board with a microcontroller that performs the first and a Bluetooth module that allows sending the measurements made, wirelessly, to the cell phone. In turn, you need to be able to...
How is Mercator Origins a piece of Assistive Tech? With the end date for the challenge round for the Assistive Tech category of the Hackaday 2023 prize fast approaching (30 May 3pm BST) I wanted to write a log on how the audio module is going. With the...
A bunch of the sensor boards arrived this week! I confess that holding them in your hand is a lot different than seeing them in Eagle CAD -- these new sensor boards are tiny. Modular Sensor BoardsThe first three (of five) sensor boards arrived,...
The hardware I used includes the Raspberry Pi B+ and Texas Instruments Sensor Tag (CC2650). I have a Wi-Pi wireless dongle and IOGEAR blue tooth dongle. I was very happy at the end of the day (okay many days) and finished the build with a nice dashboard...
How to lose your mind in three really simple steps We have all been there, more than we care to remember. You are in the middle of creative frenzy, writing your code as the Devil himself. Compile, link, grab the programmer. Fish out that ROM chip...
Here's the part I missed in my well over a decade of dismissing my implementing autobaud as "hokey at best": Ten bits make a typical serial frame. Sampling of the bits typically happens in the middle of each bit. Thus, the last bit in a single frame...
Created Two GitHub Code Development Repositories Python Code GitHub (not strictly needed, but helpful)Arduino Code GitHubPython Test (optional)I have a couple of pieces of Python code that I used to test the connections to the MyMenu...
I'm a big fan of toggle switches and tactile human-machine interfaces: think swathes of switches on the control panel of an old mainframe, or the cockpit of an airliner. For years the vague idea of a binary data input panel has been kicking around my...
NOTE: This project log was originally posted on 07/20/2023 at 18:38 EDT, but due to a misunderstanding, it had to be deleted and remade. The other night I was jotting down some notes about the Open Book, trying to figure out how to write about...
