HACKING THIS SMART BULB IS ALMOST TOO EASY

The regular Hackaday reader no longer needs to be reminded about how popular the ESP8266 is; they see the evidence of that several times a day. But what might not be quite so obvious is that it isn’t just us hacker types that are in love with the inexpensive IoT microcontroller, it’s also popping up more and more frequently in commercial products. As [Majenko] demonstrates, one of those ESP-powered devices ...

MalDuino, The Open Source BadUSB

Firmware is a type of software that provides control, monitoring and data manipulation of engineered products and systems. A USB device firmware hack called BadUSB was presented at Black Hat USA 2014 conference, demonstrating how a USB flash drive microcontroller can be reprogrammed to spoof various other device types in order to take control of a computer, ex-filtrate data, or spy on the user. BadUSB is a ...

ESP8266 16MB Flash Handling

ESP8266 16MB Flash Handling In recent weeks a number of ESP8266 devices have become available offering more than the previous defacto maximum of 4MB of flash memory. Wemos’s D1 mini pro offers 16MB of flash, and the ESP-100 claims to offer 8MB. To put this in context, the original ESP8266 modules (such as the ESP-01) offered 512KB of flash, with the more recent ones (ESP-07) 1MB and then 4MB. The maximum ad ...

Arduino LED Scroll Bar using easyEDA

Today I want to make a LED Scroll Bar as is shown in the picture above. Ten LED strips can flash in different effect by using a control board. Components LED strip, Arduino Nano, Dupont line and a control board. How to make it ? Step 1) Cut the LED strip into 10 pieces with each LED arbitrary number. Then, weld the traverse at an interface of the LED strip. Here I prefer using Dupont line to connect. Step 2 ...

Building a low cost wifi camera

Update! Here is a post with the BOM for the project. Sometime ago I came across the Arducam Mini which is quite a nice camera module from UCTronics. It is a small PCB with a two megapixel OmniVision OV2640 sensor, an interchangeable lens and an FPGA to do the heavy lifting of image processing and JPEG encoding. Priced at around 24 Euros (lens included) you can easily buy a few without hurting your wallet an ...
