New boot loaders for the WidgetBoards have been uploaded to both SVN and to the downloads area. The fuse settings have also been updated in the documentation. I’ve also integrated the Atmega328P version of the WidgetBoard into the Arduino development environment so please update your boards.txt with the one from SVN.
I have successfully re-compiled and re-flashed the firmware source to remove the console on ttyS0, as suspected the console attached to ttyS0 was the root of my problems, now avrdude will talk to the WidgetBoard! and here is my WidgetBoard booting my test blinky on ContikiOS as seen by the gateway ttyS0 now back to … Continue reading #WidgetMesh gateway now online!
I’ve had some mixed success with the serial port hack on the Airlive device since my previous post. After setting up the uclib development environment I have now successfully compiled avrdude so I can program the RFM12WidgetBoard located inside the device, however I had a couple of issues when trying to talk to the WidgetBoard. … Continue reading #WidgetMesh Gateway continued…
I’m still alive…… Its been awhile between blog entries, unfortunately this is the busiest time of the year for me at work, the few months after the Australian financial year, projects are kicking off due to funding etc. There is however light at the end of the tunnel and I’m hoping to get back to … Continue reading Update;Yes I’m still here!
Well, back from a short break away (kid free woohoo!) and onto some widget builds. I thought I’d document how I do my widget construction. I actually find building SMD devices much easier than the PTH variety. I have all my components in some neat snap together containers, this allows me to have everything at … Continue reading Building Widgets – My SMD Build Process
For the next version of the widget, I’m planning to have an on board boost regulator. This design will allows the widget to run from just about any voltage source as low as 0.7v (so NiMh will be fine) and up to 5.5v, this boost regulator in conjunction with a standard LDO regulator will give … Continue reading Widget running on the smell of a single AA
Just thought I’d post an update on what’s happening in the widget development world. Limited Production Run I have a very limited number of widget kits available for purchase. This limited batch of widget kits also include a bare prototype personality at no cost with each widget to get you started in your wireless applications. … Continue reading Widget Development Updates
I want to deploy widgets around the home, both inside and out, so I needed to find something that would allow some protection from the environment to the electronics, cheaply and easily. On the weekend while doing some shopping I found the solution in the kitchen area of the local discount store, at $1.50 a … Continue reading Widget Sensor Housings
In my previous blog entry I described adding a solar cell to the widget and how I could measure the voltage produced by the Solar Cell, however I still need to monitor actual battery voltage easily, and preferably with not a lot of additional hardware. Problems reading ones own voltage. Measuring ones own voltage has … Continue reading Reading Widget Battery Voltage
The other day when playing around with different fuse settings on the Widget Board, I incorrectly wrote the wrong values, oops one bricked board 🙁 However all is not lost. With a second working Widget Board and a simple Arduino sketch , I used the following procedure to recover from my mishap. First I installed … Continue reading Recovering from Incorrect Fuse Settings on the Strobit
Version 1.0 of the boards is progressing to the point where I’ll be starting work on v1.1, integrating user feedback and any issues on the tracker, I’ve put a few up there so please check them out, comment or add your own. Issue Tracker. I’m extremely happy to say that everything has progressed really well, … Continue reading Progress
I’ve started to document the Wireless Widget Board in the wiki, documentation is currently all over the place, but slowly getting there. Currently I’m working on the build instructions so those of you that I’ve sent PCBS to can at least have a parts list. I’ve also put up an initial bill of materials. But … Continue reading Build Documentation
I had a chance to grab a few photos of the progress so far, also helps that most of my components that I had on order arrived today so the boards has been kitted out with all the headers. Now I can plug the prototype personality in, still waiting on my crystals, switches, and diodes. … Continue reading Strobit Wireless Widget Photos
Today I did some testing on the RF side of things, nothing scientific, just walking around the house seeing if it would dropout or report bad checksums, I’m happy to reports all is working as expected (using the 915Mhz RFM12B module) The tests are done by using the RFM12B Example sketch found in the JeeLab … Continue reading Preliminary RF Tests
Today I constructed another 2 boards, very easy to do all done in around 30 minutes. This now brings the total to 3. Applying the boards with solder paste by hand, manually placing the components, bake them in the toaster oven together. This time I got the LEDs the right way around and the right … Continue reading And they multiply…
