Daniel Gilbert shares his experience of building the PinTin Nano, a Intel Edison powered portable password keeper. With this instructable, I try to solve a problem everyone has: Passwords. Accounts. Logins. All the stuff you need to get into your favourite social media site, shopping site, blog or forum (they still exist, huh?). Now, there are several ways to control your accounts: Use always the same credentials: No. Never ever do that. Seriously.

Posted on by One comment

Ole Andreas Utstumo has designed a portable electro cardiogram (ECG) recorder using Xmega A3BU microcontroller that measures the ECG signal and store it on a memory card to show a doctor later. The device is currently able to do the following – Measure the electric activity in your heart with 3 leads – Sample the signal @ 512 Hz, 12-bit and store the data on a microSD card – Operate for nearly 24 hours on a charge – Save a timestamp with the push of a buttonMore details to come!

AVR Alarm clock with temperature and humidity meter

Posted on by Leave a comment

This AVR based alarm clock uses PCF8563 for time keeping and has extended functionality of thermometer and humidity meter using DHT11. First, let me introduce you my project. I made an Alarm clock with extended functionality & thermometer and humiditymeter. Everything started when my friend (who used to bring me some old electronic rubbish and I used to check if there’s not something useful) brought me some cashing register display similar like that. When I first see them I knew that I will made from it alarm clock. I’m programmer and I used to program in many programming languages but

Arduino controlled motorized Solder Paste Dispenser

Posted on by Leave a comment

Zapta shares his design files of his Arduino motorized solder paste dispenser for SMT soldering. This is a motorized solder paste dispenser for soldering SMT boards that was inspired by this thing http://www.thingiverse.com/thing:384680. The home directory of this project is on github here https://github.com/zapta/misc/tree/master/paste_injector and it include hardware and firmware design of a compatible controller board that is Arduino compatible (it looks to the Arduino IDE as an Arduino Pro Mini). Schematic:https://github.com/zapta/misc/raw/master/paste_injector/eagle/paste_injector_schematic.pdf BOM:https://github.com/zapta/misc/blob/master/paste_injector/eagle/paste_injector_bom.csv EEVBLOG discussion: http://www.eevblog.com/forum/reviews/solder-pasteflux-manual-syringe-applicator/150/ I printed successfully using both PLA and ABS and standard slicing parameters (3 layer shells, 20% infill).
