Dangerous Prototypes: Removing third-party website tracking to protect your privacy
As of today there are no third-party website tracking services in use on this site. As geeks and Slashdot trolls we’re naturally privacy advocates. We don’t like social media tracking malware, and we don’t like to share your info with a third party. Previously we used a Google Analytics-type tracker on the blog. It was […]

Repairing the PICqueño32 dev-board prototype
In a previous video we soldered the PICqueno32 prototype. There was a big mistake though, we used the wrong PIC32 chip. In this video the old chip comes off and the new chip goes on. For the swap we used a flux sample sent by Farnell. It was fantastic! Here’s the webpage if you want […]

DE0-NANO FPGA development kit review
octal tipped us to a cheap Altera DE0-NANO FPGA Development Kit: …Now most of you will be swayed by cost so lets get that out the way – The DE0-Nano is $79USD and though education routes is only $59USD which I think is really good. Its a little more than the Papilio and XuLA boards […]

Partlist Wednesday: NPN transistors
Every Wednesday we highlight a component from the updated partlist. This week: NPN transistors Transistors do lots of analog tricks, but we only use them to switch high powered stuff with a weak microcontroller pin. Usually an LED. See the IR Toy, #twatch, PICqueno, or USB POV Toy for the sad truth. We’ve standardized on the BC818 […]

Thanks to the reviewers for considering our proposals and including thoughtful remarks. We’ve been asked to coordinate with Eric on the general topic of parts libraries and manufacturing. […]
New Bus Pirate probe cable
Seeed is working up a new Bus Pirate probe cable. It’s going to have female ends like the SparkFun cable. For the last year we’ve been using 1:1 female cables to connect the Bus Pirate to stuff. We think the connections are more secure than the cheap test clips on the old cable. The new […]
