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

I forsee folks getting free parking in the future

The author figured out how to sniff some of the garage gates and get them to trip using an 433 MHz OOK module and an arduino.  I see a future here where folks use this to bypass parking garage gates. … Continue reading

This plotter is the perfect build for kids

This plotter could not be easier to build.  4 rulers, 2 steppers, and a servo are all you need…oh and ways to bolt the rulers together.  Oh and an arduino and stepper controllers too. https://www.instructables.com/id/CNC-Dual-Arm-Plotter/

HAHAHAHA this is a pretty clever build for cutting bars the same size

The author uses an arduino and a home made encoder to measure the cuts. http://hackaday.com/2017/06/04/arduino-and-encoder-form-precision-jig-for-cutting-and-drilling/

Getting Serial data from Arduion ot RPi to MySQL with CoAP

I have heard bits about CoAP in the past, never thought past that.  Looks like CoAP could be a good simple interface for IoT builds.  This one is getting sensor data out to the rest of the system https://www.instructables.com/id/Serial-Data-From-Arduino-to-Raspberry-Pi-to-MySQL-/

OK adding this to the list of things to build

A sand/zen garden.  This looks easier to make than a CNC since its only two axis and a big magnet.  Making the “sandbox” maybe more of a challenge.  And as the article says, its been done other times too (I … Continue reading
