Bus Pirate interfacing MMA8453Q accelerometer
m8051 dead-bugged a tiny QFN accelerometer on a dip breakout board and tested it with the Bus Pirate. We were trying to work out the new Accelerometer MMA8453Q which is a I2C based 10 bit accelerometer. Bus Pirate helped us to debug the issues and also talk to the MMA8453Q chip. Thanks Boseji! Via the […]

Cheaper surface mount crystals at Mouser
We use HC-49/US surface mount crystals whenever possible. HC-49/US is like a through-hole metal can crystal, but with surface mount pads. They’re about $0.50 in 1s, while the smaller bar-type SMD crystals start at $1. Brian found a new line of crystals at mouser that’s about a quarter cheaper: I use an ABM7 XTAL on […]
Free TI op-amp evaluation PCBs
From the comments on our earlier post: Touchstone TS1001 op-amp demo board unboxing: TI offers evaluation boards for opamps as well. These are unpopulated PCBs, you can choose between inverting and noninverting configuration and between different package types. The boards can be found by searching for “dem-opa” on TI’s website. You can get them for […]
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 we’re giving away two […]
SUMP logic analyzer with 2 scope channels
hlipka made a logic analyzer with 2 oscilloscope channels that uses a Cypress PSoC chip. It works with SUMP clients like Open Logic Sniffer. Goal of this project is to develop a combination of 2-channel oscilloscope with a 32-channel logic analyzer. Sample speed will be 1 Msps, with a depth of 6k samples (when using […]
App note: LED brightness controller with 64 taps
An app note on a LED brightness controller: In this circuit, a digital potentiometer (DS1869) aids an LED-driver IC (MAX16800) in providing manual control of the LED brightness. The circuit also provides thermal protection against excessive heat and overload conditions. Thanks rsdio!

Multimeter recommendations
sqkybeaver on choosing a multimeter: …if you use eBay, for an entry i would recommend something like this with dmm (a second or third dmm is all ways good to have) this is as fairly accurate as a hobbyist would need. for a more advanced user I’d go with new BK precision 879B handheld dual display LCR […]
App note: RS-485 adapter converts data lines from full- to half-duplex
A RS-485 adapter: An adapter circuit consisting of an RS-485 transceiver (MAX3076 or MAX13086) and a voltage monitor used as a timer (MAX641X) allows an existing point-to-point full duplex circuit to function in a more-complex point-to-multipoint half-duplex system. Thanks rsdio!

Bus Pirate Zeno zit zapper hack update
Restoring a Zeno zit zaper tip was one of the first published ‘hacks’ using the Bus Pirate a few years ago. It’s still a super popular post that gets a ton of hits. Here’s some updates: Was jacking around with the Zeno again recently and figured out (as far as I can tell) how to […]
Thermal Tweeter Fail Whale
Earlier today the Thermal Tweeter printer stopped working. Probably due to rough continuous abuse. A few replacements are on the way. We dressed it up for a proper send off. There’s an eerie still in the lab now that it’s gone. According to USTREAM there were 26,037 total views and 3,694 viewer hours. The statistics […]
