Mike sent in his first Arduino project, an internet troll sniffing rat: Sometimes we like to take a few minutes away from Hackaday to spend time with our families. But just when you take your eyes off of the incoming comments, Trolls are bound to strike. Well, [Caleb] and I found a solution to the […]

3D LED cube thing
MichaelZ spotted a commercial 3D LED cube. I saw this at a home construction materials show in Taiwan 3D LED cube thing In person they are very impressive. There are vertical strips of SMD LEDs and the light changes color. Amongst patterns they can sort of swirl around like a cloud or school of fish. […]
HUGE wireless RGB LED display
siklosi saw the post about using a wifi router as an Arduino wireless serial connection, and shared his own take. This RGB LED wall is plays Winamp visualizations, and more. The LEDs are driven by Rainbowduinos, the Rainbowduinos are connected to the PC using the router as a wireless serial connection. I made this “little” […]
Logic Sniffer back in stock at Seeed
The Logic Sniffer is back in stock at Seeed Studio. The price has increased $5 to $50, including world wide shipping.

DEMO: MMA7455L 3-axis accelerometer
Here’s a demo of the MMA7455L 3-axis accelerometer in SPI mode using the Bus Pirate. We’ve got this sensor on a breakout board for $15. The MMA7455L has: 2/4/8g selectable measurement range 10bit or 8bit output force and pulse detection with interrupt I2C and SPI interface 3.3volts Get the MMA7455L breakout board for $15 at […]
Alternative Logic Sniffer client v0.9.2
Jawi just released version 0.9.2 of the forked SUMP logic analyzer client that works with the Logic Sniffer. Download it here. Here’s the major updates, see the changelog for more: Added 1-wire decoder tool. Still experimental, but should be usable Improved support for OSX Leopard (10.5). Thanks to Brent for testing/verifying this Some improvements for […]
Free PCB Sunday: MMA7455L breakout board
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week we’re giving away two […]
Bus Blaster v2 development
We got a big box of PCBs from Seeed this week. This is an update of the Bus Blaster (in test production now) with a CPLD instead of discrete logic buffer chips. The CPLD is connected to the secondary JTAG B port of the ft2232. This should make it like a mini CPLD development board, […]

eHaJo has the Bus Pirate LCD adapter
eHaJo is the first reseller to carry the Bus Pirate LCD adapter. Lots of LCD adapters have been sold, but we haven’t heard much from users. We’re hoping that means everything is working great. eHaJo has the Bus Pirate, LCD adapter, probe cable, and case in stock and ready to ship. Learn more about becoming […]
Boost driver for long LED strings
rsdio tipped us to an app note on a Boost driver for long LED strings. The long strings of LEDs commonly found in TV and display backlighting, street lights, and parking garage lights require a current driver capable of producing high voltages. This reference design provides such a driver using the MAX16834, and demonstrates how […]
NEW PRODUCT: MMA7455L 3-axis accelerometer breakout board
MMA7455L is an inexpensive 3-axis accelerometer with adjustable measurement range of 2/4/8g. It can communicate with microcontrollers through an SPI or I2C interface. This chip is only a few dollars in onesies, but it comes in a leadless LGA-14 package. It’s a challenging chip to solder, so we though a inexpensive breakout board might be […]
