Size 3 Linux Tibbo Project PCB (LTPP3)
Tibbo Project System (TPS) family now includes a Linux-based Tibbo Project PCB (LTPP). Based on the powerful 1GHz Cortex-A8 Sitara CPU from Texas Instruments and carrying 512MB of RAM and 512MB of flash memory, the new LTPP3 board runs our own, highly polished distribution of Linux that capitalises on the latest kernel and drivers.
PBJ Stacker: It's not something found in your kid's bag lunch. I organize using peanut butter jars, stored in stacks using a series of laser-cut trays. (by John Baichtal) on #hackaday

PBJ Stacker
I store pretty much everything in peanut butter jars. However, trying to stack them up makes for a very messy heap. I created some trays to help me organize the mess.
RFID audio book reader for my nearly blind grandfather: An RFID controlled audio book reader to help the visually impaired enjoy audio books. Already in use by my nearly blind grandfather. (by Willem) on #hackaday
https://hackaday.io/project/2698-rfid-audio-book-reader-for-my-nearly-blind-grandfather
RFID audio book reader for my nearly blind grandfather
I built this project to help my 93 year old grandfather, who suddenly became nearly blind, enjoy audio books. He uses it every day and averted the onset of a depression. I built it because of the shortcomings of devices like iPods which are nearly impossible to use without good vision, and the existing solutions that either have a big learning curve, or read books in a robotic voice. My solution uses DVD cases that contain an RFID card and have the title printed in large on the front. By using objects the size of a book, and only one book per case, books remain as tangible objects as the books my grandfather was used to. The player is powered by a Raspberry Pi and keeps track of elapsed time for each book, so when listening to multiple books, or books and music, going back to a book will resume playback where it was previously stopped.
Reprap Neumann: An easy to build, open source self replicating 3D printer with a rock bottom bill of materials that maintains accuracy when reproducing (by TTN) on #hackaday

Reprap Neumann
NOTICE: This project has been put on the back burner. Pictured is only the Y axis complete. Reprap Neumann is an free open source 3D printable 3D printer with a rock bottom bill of materials, named after John Von Neumann who made major contributions to a number of fields including research on self replicating machines. This printer will be easy to build, assemble and calibrate, while still maintaining accuracy when replicating itself; this is critical for a self replicating machine. By going for a rock bottom bill of materials, a lot of this printer will have to be printed. The target cost of the machine is 200 US dollars for the hardware and electronics. Ideally, the filament used to print this printer will be recycled from waste plastic, such as shopping bags, drinking bottles, bottle caps, etc. Link to CAD files can be found below, left.

Micro AAA Palm Drill
Drill didn't quite have the torque i wanted. it was very easy to over torque and break the gearbox teeth. But if your gentle it works. I also made a super cap powered version that charged from USB in 20 seconds and ran for about 5 minutes. All Files i could find are in Dropbox.
SMART SHOE: This project is to solve the difficulties of visually impaired people. And give them additional facilites like knowing their loction etc.. (by vishvanthan) on #hackaday

SMART SHOE
As a measure of enhancing the difficulty present in walking for the blind people the project is being proposed.The following sensors for being fused in shoes 1.ultrasonic sensor 2.Gyroscope 3.GSM 4.piezoelectric As the ultrasonic sensor is capable of identifying obstacles and the output of the ultrasonic sensor can be connected to a vibrator which can be held in hands of the blind person.If any obstacle is detected then the person can able to identify it through vibration.The Gyroscope is used to find the orientation of the person.Finally the GSM is used to loacte the person in case if he/she lost their path.An [http://path.An] additional advantage is that through piezo electric charge can be generated in each steps of walking. The output of the sensors are obtained through cloud platform(bluemix,thingworx).The data from the cloud is retrived either through e-mail or through mobile application.
Python MicroService Bus for IoT : Python Peer to Peer MicroService Bus for IoT Messaging Framework (by Mark Traverse) on #hackaday

Python MicroService Bus for IoT
Latest work: I am currently well along a personal project to build a simplified data-driven MicroService Bus in Python to integrate RPI HAN nodes, ESP IoT wifi devices., communicating freely with the world of telemetry and cloud messaging service capabilities (think ESB for the PI). Key Objective: Single install sw to configure RPI/Linux as a Home Area Network. Harness all io capability I2C, 1-wire, GPIO, API's to transfer data and commands over MQTT telemetry and integrate with all home Smart devices, sensor networks etc. Home Automation is not really a good description more the vehicle and standardisation for exchanging home information.
Super Simple Load Driver Circuit: Turn loads on and off with your Micro! Use 5V to control up to 100V. Add a motor, solenoid, or get creative! P channel or N Channel. (by houser636) on #hackaday

Super Simple Load Driver Circuit
This is a super simple circuit to control loads using a small amount of power from a microcontroller. With the use of 2 N-channel MOSFET's and 2 P-Channel MOSFET's it is possible to build a very simple H-Bridge driver. This allows you to control the Polarity/direction of a DC motor.
Check out the kickstarter project to get your MOSFET Breakout board today. I need your support!

microBox - Linux Shell on Arduino: Arduino bash for Linux Shell look and feel on Arduino with esp8266 support (by wastel7) on #hackaday
https://hackaday.io/project/4405-microbox-linux-shell-on-arduino
microBox - Linux Shell on Arduino
microBox is a Arduino library that provides a interface with Linux Shell like look and feel for Arduino applications. With microBox own commands and application parameters are made accessible to the user within a virtual Linux filesystem tree. The parameters can easily be accessed by Linux standard commands. The user can navigate within the virtual filesystem with cd and ls like in a Linux Shell. The commands cat, cd, echo, exit, loadpar, ll, ls, savepar, watch and watchcsv are available in microBox. Own commands can simply be added via callbacks. Application parameters are found inside /dev, which are completely user defined. They enable access to variables of the Arduino application and support the datatypes int, double and string. microBox features a builtin command history and a basic autocompletion (via tab) for commands and parameters. Furthermore a microBox variant with support for esp8266 WiFi-modules exists. It comes with password protected login functionality.
Macbook Pro RAM upgrade: Soldering in 16GB of RAM. Easy or buy a new Mac after the attempt? ;) (by Sebastius) on #hackaday

Macbook Pro RAM upgrade
Please note that everything below is theoretical at this point, do NOT desolder your RAM just yet ;)I'm still in love with my by now classic Macbook Pro early 2015 13". It's a wonderful little Macbook but two specs are becoming a bit... outdated and that is the disk-size and the amount of RAM. Mine came with 8 gigabytes worth of RAM (max was 16GB and that was way too expensive back then). A random google showed that it is actually possible to upgrade soldered RAM chips on some Macbooks, so now i'm investigating mine. My inspiration was this video on Youtube:https://www.youtube.com/watch?v=CTsEJ49LLsQ [https://www.youtube.com/watch?v=CTsEJ49LLsQ]
Note: this projectblog uses some photos (or crops thereof) from iFixit.com [http://iFixit.com] from their Macbook Teardown, which is a great read in it's own right.
