Secret Messages Could be Hiding in Your Server Logs

[Ryan Flowers] writes in with a clever little hack that can allow you to hide data where nobody is going to go looking for it. By exploiting the fact that a web server will generally log all HTTP requests whether or not it’s valid, he shows how you can covertly …read more

Four Years Of Learning ESP8266 Development Went Into This Guide

The ESP8266 is a great processor for a lot of projects needing a small microcontroller and Wi-Fi, all for a reasonable price and in some pretty small form factors. [Simon] used one to build a garage door opener. This project isn’t really about his garage door opener based on a …read more

Tea Bot Solves Another First World Problem

In the movie Wall-E, future humans live in floating chairs and have everything done for them. Today, we grumble if we have to go to physically find a light switch or a remote control. How far away can floating chairs with screens be? T2, the Tea Bot, gets us one …read more

Control Anything With A Chat Bot

In the world of Internet of Things, it’s easy enough to get something connected to the Internet. But what should you use to communicate with and control it? There are many standards and tools available, but the best choice is always to use the tools you have on hand. [Victor] found himself in this situation, and found that the best way to control an Internet-connected car was to use the Flask server he already had.

The remote controlled car was originally supposed to come with an Arduino, but the microcontroller was missing upon arrival. He had a Raspberry Pi around, …read more

Easy Time-lapse Video via Phone and Command Line

A good time-lapse video can be useful visual documentation, and since [Tommy]’s phone is the best camera he owns he created two simple shell scripts to grab time-lapse images and assemble them into a video. [Tommy]’s work is just the glue between two other things: an app that turns the phone into an IP camera with a web server on the local network, and the ability to grab a still image from that server on demand.

The app he uses for his iPhone normally serves video but has an undocumented feature that allows single frames to be downloaded by adding …read more

7-Segment Digits Slide Stylishly on This OLED Clock

Over at Sparkfun, [Alex] shared an OLED clock project that’s currently in progress but has a couple interesting twists. The first is the use of a small OLED screen for each digit, to which [Alex] added a stylistic touch. Digits transition by having segments slide vertically in a smooth animated motion. It’s an attractive effect, and the code is available on his github repository for anyone who wants to try it out.

[Alex] also found that by using an ESP32 microcontroller and synchronizing the clock via NTP over WiFi, the added cost of implementing a real-time clock in hardware becomes …read more

Hackaday Prize Entry: Minimalist HTTP

For his Hackaday Prize entry, [Yann] is building something that isn’t hardware, but it’s still fascinating. He’s come up with a minimalist HTTP compliant server written in C. It’s small, it’s portable, and in some cases, it will be a bunch better solution than throwing a full Linux stack into a single sensor.

This micro HTTP server has two core modules, each with a specific purpose. The file server does exactly what it says on the tin, but the HTTaP is a bit more interesting. HTTaP is a protocol first published in 2014 that is designed to be a simpler …read more

Yet Another IoT Botnet

[TrendMicro] are reporting that yet another IoT botnet is emerging. This new botnet had been dubbed Persirai and targets IP cameras. Most of the victims don’t even realize their camera has access to the Internet 24/7 in the first place.

Trend Micro, have found 1,000 IP cameras of different models that have been exploited by Persirai so far. There are at least another 120,000 IP cameras that the botnet could attack using the same method. The problem starts with the IP cameras exposing themselves by default on TCP Port 81 as a web server — never a great idea.

Most …read more

Apple II Web Server Written In BASIC

The Apple II was the machine that many say launched Apple as a company. As with many popular computers of the 1980s, the Apple II maintains a steady following to this day who continue to develop new hardware and software to keep the platform alive.

[deater] had scored an Uthernet II Ethernet interface for his Apple IIe, based off the venerable W5100 chipset. He decided to have some fun and wrote a webserver for the Apple II in BASIC. The program sets up the Ethernet card with a series of PEEKs and POKEs, and then listens out for incoming packets …read more
