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, […]
Facebook free PCB Friday is on the way. Don’t forget to share your current project in the comments or the forum. Here’s a summary of major developments over the last week: There’s 3 weeks left to enter the Open 7400 Logic Competition 7400 competition entries: Money counter, Discrete logic POV clock, Discrete servo driver, and […]
Bus Blaster v2 JTAG debugger is back in stock at Seeed Studio.The cool thing about the Bus Blaster is that it uses a programmable logic chip as a buffer. It can imitate different types of programming hardware with a simple USB update. This batch is a new revision (v2.5). It includes a button and LED […]
Cliff bought an Amani64 CPLD shield for the Arduino, he had no way to program it except: I did have a Bus Pirate on hand, the ‘Swiss Army Knife’ of digital hobbyists. He successfully uploaded the LED blinking firmware onto the Amani64 with the Bus Pirate JTAG XSVF player. Now he is free to develop his CPLD skills. Get your […]
robots has some new updates on the PiratePICloader project: I have just committed HUGE changes to the piratepicloader. (HUGE = svn diff was about 2000 lines) Changes are: new data loader (fixed bug in hex file generator) new memory storage (memory.[hc]), by using simple link-list, and memory cells of size of flash page redesigned pic/family/protocol tables […]
rsdio writes: this was announced on April 1, and somehow I missed. I’m sure they’re all gone by now, but the links still seem to work The MAXADCLite evaluation (EV) kit is based on the MAX11645 ADC, which integrates a multiplexor, FIFO, sequencer, and reference, all for the same price as a competitive stand-alone ADC.

Last week Ian did a Skype interview with Open Source Hardware Junkies. It’s up today, listen in if that’s your kind of thing: Need to figure out a chip…fast? Bus Pirate may be just what you have been looking for. Designed by Dangerous Prototypes, the Bus Pirate is a universal bus interface that can slash […]
This driver is used in LED replacement lamps for MR16 halogen bulb sockets. It’s compatible with common dimmers: The MAX16840, an LED driver that employs a proprietary architecture to ensure flicker-free, dimmable operation with electronic transformers and cut-angle dimmers. Maxim’s patent-pending approach enables the design of retrofit LED lamps that can replace halogen MR16s without […]
Peter posted a fix to get the C18 compiler for PIC microcontrollers working under Linux: C18 doesn’t work under Linux . I made some scripts to fix errors in the headers. The package also contains scripts and instructions to compile C18 libraries under Linux. Via the comments.
The MAX2209A is an efficient and fast RF power detector: Fast RF step-response allows faster tracking of the output envelope, ensuring more efficient and more accurate PA control Shutdown feature allows lower overall current consumption Small size saves board space You can check out the complete datasheet. Thanks rsdio!
Now you can pay with your American Express or JCB credit card at Seeed Studio. Seeed already supports MasterCard and Visa. Seeed still recommends PayPal, expecially for your large orders. With Paypal there is no spending limit and the service fees to customer and retailer are the lowest.
The nRF24LE1 is a single chip radio that can be used with a microcontroller for low power wireless stuff. It has lots of extras like an ultra low power analog comparator for voltage level system wake-up. Nordic Semiconductor provides an RF protocol stack and applications for microcontrollers. Via MDFLY.
Cellular mobile devices and Google Maps can be used to provide fast and accurate localization without GPS. Using a database of cell coordinates, the location of an object can be precisely determined. The cell names, coordinates, and the maximum distance allowed between the cell and the phone before it switches towers must be known first […]
