OverviewCurrently there are over 422 million people worldwide suffering from diabetes. 28.5% of them suffer from Diabetic Retinopathy(1) . 50% of diabetics are unaware about the risk of losing their vision(2). The number of cases of diabetic retinopathy...
The transmitter in the fourth picture uses a few more parts. I had a 3.3V breakout board and the signal reached only about a yard. So I added a 555 voltage doubler to Albert's hardwarehttp://www.talkingelectronics.com/projects/50%20-%20555%20Circuits/50%20-%20555%20Circuits.htm...
The final version of the firmware has the following features:Configurable brew and steam temperatureConfigurable grinder timerAudible beep when temperature for selected mode is reachedAuto-flush when switching from steam to brewGrinder-only mode with...
First, I used Sketchup to design a tilted box with all the buttons and dials I wanted (dxf available on github).This dxf was loaded into CamBam to make some gcode for the lasercutter to use. The engraving was set to a high movement speed with a low power...
With my project you can cut cables with sizes of 0.75 mm2 up to 2.5 mm2 and i also think that it would handle 4 mm2. The length is mutable from 1 cm to 1 m and you can order up to 100 cables. The accuracy is pretty high, the lentgh varies only about...
Laser cutter file (see github link opposite). Colours are: Red - etch, Green - first cut, Blue - second cut, Cyan - CAD notes. Also a file which contains the previous revisions (on github), good and bad, which might offer some insight into my design...
The lossy text compressor consists of a Perl script and accompanying thesaurus. On startup, the script opens the thesaurus file, and constructs a hash of "word" to "shortest synonym of that word". Some words are filtered out, e.g. abbreviations and 2-letter...
Current test is done on breadboard. One for the arduinos is reading a 24VDC sensor and counts postcards in stacks of 24. once 24 is reached it turns on pin 13 and restarts the counter. The second arduino receives high input from first arduino and triggers...
Building this was a real treat. I had long since reached the point where nearly every kit was far to simple and it was fun to get back into the action so to speak. V1 never worked and V2 worked with some modifications. I eneded up using 8 diodes, 31...
One time too many, I reached over for a drink while wearing VR goggles, only to knock over the glass and spill beer everywhere. This project is a somewhat tongue in cheek solution for that. Sellotaping a pint glass to a motion controller allows us to...
The idea behind this project is to create a dynamic environment of heat and cold to maximize the temperature differential on different sides of a thermopile made from numerous thermocouples. The basic thermocouple housing unit will have two chambers,...
Based on an ATmega328P running the arduino bootloader and the ROS serial framework, the module can monitor up to a 5 cell LiPo battery, giving data on temperature and cell voltage. User specified (set to defaults) values for discharge and temp warnings...
We will be scanning IoT enabled personal mobile devices for measuring crowd. These can be smartwatches, mobile phones, or beacon type devices. We will count all of them and upload this information to the cloud. We are using PSoC® 6 WiFi-BT...
I often forget to check my regular mail, so much that sometimes I miss deadlines for various things. It seems weird to still use regular mail in this day and age, but there's no going around it.I decided I wanted to know exactly when the mail is delivered...
