Bus Pirate extended logic analyzer firmware

flubberlab made an alternate firmware for the Bus Pirate with extended support for the SUMP logic analyzer protocol. This firmware works with the latest Jawi client and has lots of features: Sample clock source (32 MHz CPU clock): Internal, 5.9 Hz to 108.8 kHz, jitter = -0/+250 ns External (via AUX pin), rising or falling, […]

Yet another Arduino GSM shield

Boris tipped us to another SIM900-based GSM/GPRS wireless data shield for the Arduino, this one is from Open Electronics: This is a very low cost and simple Arduino GSM and GPRS shield. We use the module SIMCom SIM900. It’s the cheaper module now available in the market. To connect this module to Arduino I make […]

GPRS Arduino shield with SIM900 module

McZ tipped us to the GPRS shield using the new SIM900 cellular data module in a followup to our position location with GSM cellular post. GSM/GPRS 850/900/1800/1900MHz … for voice, SMS, Data, and Fax in a small form factor and with low power consumption. It is controlled via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced […]

Bus Pirate based RFID development board

Stefano writes: I’ve made a custom RFID programmer for ST’s SRIX4K chips picking as a base design your Bus Pirate.  It uses the CRX14 chip, via I2C. With a custom software you can easily read/write/modify the tag memory. I’m implementing a plugin structure in the software, I will release it asap. Via the contact form. […]

Alternative Logic Sniffer client v0.9.4 RC1

A release candidate of Jawi’s Logic Sniffer client is available for beta testers. It took longer than originally anticipated, but it is finally available: the first Release Candidate (RC) of the 0.9.4 version! Implemented features and issues solved in this release: VCD exports ignore selected channel groups Verify frequency measurement with RLE captures Support OLS-device […]

Re-animating the PDP-11/70 with CPLD, ethernet

J. Peterson updated a PDP-11/70 console with an ethernet controller and a CPLD to control the blinking LEDs: I’ve always missed that visual and tactile aspect of computers that’s been lost since the advent of microprocessors. When a console for a PDP-11/70 came up for sale on Ebay, I couldn’t resist the opportunity to bring […]

Free PCB: CPLD development boards

To celebrate the launch of our new CPLD development boards we’re giving away PCBs. Just ask for a CoolRunner-II or XC9572XL dev-board in the comments, if you have a project in mind we’d like to hear about it too. Assembled CoolRunner-II and XC9572XL development boards are available now for $15.

NEW PROTOTYPE: XC9572XL CPLD development board

Ever get stuck choosing the right logic chip combination or voltage level translator? Give up the hunt and create your own custom logic chip. CPLDs can give you the logic you need, with the pinout you want, while saving board space and board revisions. The Xilinx XC9500XL family has some of the cheapest and readily-available […]

NEW PROTOTYPE: CoolRunner-II CPLD development board

Ever get stuck choosing the right logic chip combination or voltage level translator? Give up the hunt and create your own custom logic chip. CPLDs can give you the logic you need, with the pinout you want, while saving board space and board revisions. The CoolRunner-II XC2C CPLD has two separate banks of pins that […]

STATUS UPDATE: Nokia LCD backpack

We’re trying a new Monday post with status updates on new projects currently in production. This will cover project development, and gritty details like last minutes changes and production problems. This is a simple USB backpack for SparkFun’s cheap color LCDs. A PIC 18F24J50 controls the LCD from a USB connection, and a small booster […]

Bus Pirate repair

Sal_The_Tiller posted a Flickr photoset of his Bus Pirate repair. Delicate surface mount surgery to replace a broken PIC chip: …I’ve got a permanent workspace and some projects that could use a Bus Pirate, but I’m too cheap to buy a new one. Therefore I decided to replace the PIC24 chip by hand. Using a […]
