Here's another interesting glitch attack: a regular Smartphone. I've made a small demo video to show you what happens, I just presented this at the HTCIA Atlantic conference here in Halifax, NS, Canada. So I thought I'd share it more widely as I bet...
First off - I decided to write some FAQs. I was going to add them to the main project details, but I've hit a maximum character limit in my detail! So for now I've copy/pasted them here, sorry for the big old wall of text! I also wanted to talk about...
So, in case you are bored and want to do something different in the weekend, this is the exact step by step to help you burn 20 hours.1. Buy a perfectly good 1:16 or bigger RC tank from RC store or Amazon for 99 bucks, mine is a Tiger 1 tank.2....
One of the trickiest sensors to monitor is an RTD, aka resistive temperature device, imho. They're relatively simple where their resistance changes over a temperature range. These types of sensors are used to monitor coolant/water temps, oil temp, and...
Not a moment has gone by that I've been considering various solutions to the 14V rail problem. The previous plan was going to involved a simple charge pump to provide the input voltage to the 14V LDO. The current LDO being used has a max input voltage...
Further refinement of the power subsystems are making life easier. I'm tweaking things as the BOM and initial part selection are finalized and slimmed down to reduce the number of unique components and that includes moving to a fixed output LDO for the...
I'm about ready to pull my hair out. Really, OMG, this was painful... Alright, regain composure and drop curtain.Edit: Heh, looks like Dave covered this a *just* few days ago so have a look if you've not already---------- more ----------So, there...
We ended up getting a lot of attention for the project and were asked to present at the 6th Annual National Symposium on Renewable and Sustainable Energy. We decided it would be time to start looking more into aesthetics...And so the shell was born....
So i built a groundstation to test the project in the field. the plan is to feed it from a 12 volt to 230 volt inverter in the back of a car and drive to an open field to test performance at one meter. When a usable feed is achieved at 500 meter (~1600...
So, the specs for the machine are evolving as I go, but for now I've settled on a 6 inch X, 4 inch y, and 2 inch z build volume. While this may seem absurdly tiny for a mill, the real goal isn't for this to be a regular flexible mill. By controlling...
So I've started working on the software to be used to hang all this stuff together.Afterall the hardware design is nice to use for this project, and indeed with practically ANY linux distribution can be a regular standalone webserver or FTP or database,...
In the past couple days I've added playbooks to the project github source which allow you to provision an MQTT broker server on Amazon's EC2 cloud and set up a basic device cloud. Check out this video to see a walkthrough of setting up a server...
I hooked up the ground fault test box again, and took some measurements. With a calculated ground fault of 0.09A I was getting an peak A rms reading on the arduino of 0.05A it was regular but not constant. I was able to measure a calculated...
A lot of embedded/home-automation server demos and tutorials with WiFly and arduino use html forms with submit buttons on their websites to send HTTP 'GET' or 'POST' requests to change an output on the arduino, and in turn reload the entire page with...
I did not know PLCC-6 packages also came in a 3mm version. Now I do.Luckily I happen to have a bunch of clear 5050 RGB LEDs laying around. They will have to do for initial testing while I wait for more diffused ones to arrive. Clear LEDs are not...
