Free PCBs are being mailed. We’re trying really hard to find a way to go to Singapore’s first Maker Faire at the end of the month. Our USB talk was accepted to the Open Hardware Summit so we’re working on the presentation now. In response to Dave’s suggestions we made modifications to our Bus Pirate […]

USB power supply with a PTC resettable fuse
Schazamp finalized his USB power supply. It features the MCP1824S linear voltage regulator, a PTC resettable fuse, and an ON-NONE-ON SPDT switch. You can chose the output from either the 5v USB line or the voltage regulator. Via the forum.
Bus Pirate on EEVblog and 2×8 connector support on LCD adapter
Dave over at EEVblog tested an HD44780 LCD, and he used the Bus Pirate and LCD adapter in his demo. In the video he works with an LCD that has a 2×8 header, but the LCD adapter only supports a 1×16 type. Here’s a prototype LCD adapter board updated with an optional 2×8 LCD header. […]
SketchUp tip: How to make 3D previews
Squonk shared a small tutorial on how to make ‘3D Warehouse‘-like previews for your SketchUp 3D Models. It involves installing and using the SketchUp Web Exporter plugin: This tool will create in the given directory a collection of JPEG pictures and an HTML file containing the JavaScript code to animate the panorama, as well as […]
Arduino based line following robot
Erdabyz finalized his Arduino-based line following robot. The design is open source and you can download the project files in the forum. He has 20 board which he’d sell for $3.5 +shipping. Via the forum.
App note: Using LT5400 high precision resistor neworks in high precision analog designs
Here is a design note from Liner Technology explaining how using their LT5400 matched resistor networks in your analog design can improve it’s precision by an order of magnitude. The actual performance of precision amplifiers and ADCs is often difficult to achieve since data sheet specifications assume ideal components. Carefully matched resistor networks, such […]
Free PCB Sunday: Pick your PCB
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 two random commenters will […]
App note: DSP library for LPC1700 and LPC1300 microcontrollers
Here is a reference guide from NXP for the DSP library made for LPC17xx, and LCP13xx microcontrollers. You can download the library here. The DSP library has been developed as a commonly used set of DSP functions optimized for the NXP Cortex-M3 LPC1700 and LPC1300 family products. Most functions have been implemented in Thumb-2 assembler […]
App note: Using Atmel’s DataFlash ICs
Atmel describes their DataFlash memory chips and how to interface with them: The DataFlash is perfectly suited for digital voice-, image-, code- and data-storage applications, especially where low power consumption is required. In these storage applications, the DataFlash’s small page size not only makes it easier to manipulate data, it also increases storage efficiency.
USB Infrared Toy v2 back in stock
USB Infrared Toy v2 is back in stock at Seeed Studio. You can use it as a remote control with your computer, view infrared signals on a logic analyzer, capture and replay remote control buttons. You can get IR Toy v2 for $22.05, including world wide shipping.
App note: More about capacitive touch sensing
A while back we wrote an app note post about the Capacitive Sensing Module available on some PIC microcontrollers. As a follow up we are posting a guide to the CSM module written by electronicsbasecom in the forum. Recently I started to work with mTouch CSM module. It sounded like extremely interesting and high performance hardware […]
Workshop Update for July 13th, 2012
We played with the site theme a bit. There’s a temporary theme on the wiki right now. We sent a few projects out for a quote, including an acrylic case for the ATX power supply. WordPress, plugin, and server updates went smoothly today. In hardware design we fixed the little spelling mistake on the Part […]
Nehebkau: Laptop controlled keyboard and mouse emulator
Frank designed, and built a Laptop controlled keyboard, and mouse emulator for his Raspberry Pi. It is designed around two microcontroller with USB device capability. One is connected to a Laptop, from which it receives it’s mouse and keyboard data, while the other is connected to the Raspberry Pi to which it emulates a mouse, […]
EzPSoC3 Ethernet adapter
Kmmankad designed and built an Ethernet adapter for his EzPSoC3 Cypress PSoC3 development board. It features the Ethernet to serial IC ENC28J60 and an open source stack he has written, that is available at github. Via the forum.
Free PCB coupon via Facebook to 2 random commenters
Every Friday we give away some extra PCBs via Facebook. This post was announced on Facebook, and on Monday we’ll send coupon codes to two random commenters. More PCBs via Twitter on Tuesday and the blog every Sunday. Don’t forget there’s free PCBs three times a every week: Free PCB Sunday. The classic. Every week, […]
Week in (p)review July 13, 2012
Here’s a summary of major developments over the last week. Free PCB Friday is coming up soon. WORKSHOP VIDEO: Favorite Bus Pirate features PARTS LIBRARY: 85×56 credit card sized standard PCB template 3D Model: FT2232H Breakout Board v1a Only 16 ATX Breakout Boards left Logic Sniffer back in stock at Seeed Another Eagle 6.xx library […]
Unboxing of the Meizu MX Android phone and gaining root access with the Bus Pirate
Adam unboxes the Meizu Mx and gets root access using the Bus Pirate. The phone is torn down to the main-board to gain access to the UART test points on the board. After that it was a simple matter of connecting the Bus Pirate to the phones UART lines. Also check out Adam’s rant on […]
Workshop Update for July 12th, 2012
Like every Thursday we spend a lot of time in video production. We did manage to get the latest two versions of the Part Ninja in the free PCB drawer. Beware, the version 1b doesn’t support battery power supply, while version 1c does. We continued to work on the firmware documentation for the secret project. […]
Another Eagle 6.xx library fix for Linux users
A link to this guide was left on yesterday’s post about fixing library issues on Eagle 6.xx Linux versions. The difference to yesterday’s guide is that this one provides links to all the missing files, instead of having them packaged in one archive.
Rotating digital picture frame
Marcus designed, and built a servo powered rotating digital picture frame, that rotates depending on the picture orientation. A 2.4” LCD is mounted on a servo, while both of them are controlled with a small 28pin PIC32 connected to an SD card. I connected a 2.4″ LCD with a resolution of 320×240 pixels which I […]
