Fresh hacks every day
This little board serves as a current gear indicator for a motorcycle. It was designed with the Suzuki V-Storm motorcycles in mind as they have a sensor built into the gearbox. Other gear indicators rely on sensors on the shifters themselves, but reading the voltage level from a gearbox sensor gives much more reliable information. The voltage measurement is handled by an ATmega88 … [Read more...]
Here's a bit of simple home automation using hacks with which we're become pretty familiar. [Mrx23] combined OpenWRT, a microcontroller, and a set of RF controlled outlet switches to add automation to his plug-in devices. An RF remote that controls the switched outlets has been connected to an Arduino. The router communicates with the Arduino via a serial connection. And the router is controlled … [Read more...]
Inside this box you'll find a La Fonera wireless access point. [Emeryth] and his band of miscreants built this portable device for WiFi security testing. The AP is running OpenWRT and has been set up to use the 16x4 character display as a terminal. An ATmega88 connects the LCD as well as six buttons to the UART of the La Fonera. From there, a set of Ruby scripts takes care of the communication … [Read more...]
This thrift shop organ gets a new life as an 8-bit music maker. Called the Chipophone, it relies on an ATmega88 to produce sounds that you might associate with classic video gaming. [Linus Akesson] takes us through all of the different sound settings in the video after the break, including performances of your theme music favorites. The original organ uses transistor logic making it rather easy … [Read more...]
[Sprite_TM] outgrew the features of the cheap unmanaged TL-SG1005D switch he was using on his home network. Instead of buying a new and much more costly switch he cracked the cheap one open and found that the RTL8366SB chip inside possessed the ability to work harder but was crippled for sale as a low-end model. It wasn't as easy as that oscilloscope firmware upgrade we saw a while back. He had to … [Read more...]
We've had a few folks send us info about their vehicle display hacks after seeing [Will O'Brien's] motorcycle computer a few days ago. On the left we have a display for an electric vehicle. [S1axter] is using a 4.3" TFT screen to display charge information for each battery cell in the car. An ATmega88 collects the data and sends it to a breakout board with an LCD controller on it. To the … [Read more...]
Above is a new demo video called Phasor developed by [Lft]. It is run from an AVR ATmega88 and a few passive components, and the result is pretty amazing. [Lft] goes into detail about the tricks he used to get this up and running. The chip is clocked at 17.73447 MHz which is exactly four times the frequency of the PAL color carrier wave which allows him to fake a smooth signal. He also uses a … [Read more...]
