Interesting build to help stroke folks recover

Basically its a robotic physically therapy machine for the hand.  I wonder if you could use it for other things, like, muscle memory for playing a song on a piano. Hackaday Prize Entry: Post Stroke Spasticity Rehab Helper

Make an MQTT water leak alarm

Nice build, takes an ESP and makes it into a wireless water alarm to alert your home system or phone.  Me…I would like a little more security on the device myself. http://www.instructables.com/id/ESP8266-Water-Leak-Detector-MQTT-Homie/

Make a bigger CDROM based CNC

The author basically extended the parts from a CDROM to make a bigger CNC.  Only didn’t use the CDROM motors… http://www.instructables.com/id/How-to-Make-Mini-Home-Made-CNC-Machine-Arduino28BJ/

Another DVD CNC/Laser engraver

But this one has some 3D printed parts to make it a bit easier to build.  It looks nicer than some of the homebrews I ahve seen too. http://www.instructables.com/id/Arduino-CNC-Laser-Enrgaver-From-DVD-Drive/

Convert ESP to wireshark

Why? well mostly to debug the board to see its speed limits,etc. ESP to Wireshark

Interesting Rain gauge…looks easy enough…just need plans

Its an interesting rain gauge that looks pretty straight forward to make.  But the authors have not released plans yet. Low-Cost Rain Gauge Looks for Floods

Another ESP8266 wifi jammer

Does a de-auth attack.  Seems pretty simple enough.  I wonder how robust it is . Hackaday Prize Entry: Don’t Build This

Another nice plotter build

I seem to see alot of these being built these days with an arduino based controller. Robot Draws Using Robust CNC Original site: http://www.arnabkumardas.com/cnc.html

Simple write up to cheapify the aTiny

Basically how to make one from just the chip.  I think I would spend the $3 for one myself.  But if you need to have a bunch of them….maybe… https://www.instructables.com/id/1-Smallest-Arduino-DIY/

Crypto for the IoT

This is for real embedded system that have very limited memory and CPU.  Bascially its adding AES to the ESP family over MQTT. Practical IoT Cryptography on the Espressif ESP8266
