Do you have a J-Link Compact and have noticed it doesn’t work with some USB C to C cables?

Have you ever wanted to debug your microcontroller over USB-C?

Quick Note This was originally a Twitter thread back in March, 2020.

Ever wonder if your USB C cable is USB2 or USB3?

It’s been over a year since I wrote about my weather station project.

I’m not sure exactly when I became interested in building a weather station.

Nui is an IR controlled volume controller for analog audio.

As you might, or might not have, heard, I left my last job in May.

A few years ago, I bought a couple of these analog gauges(galvanometers) at the electronics flea market.

What is this?

This year’s work holiday party was Back to the Future themed.

After last years DEFCONBOTS competition, I decided to try something completely different.

The last turret update (with actual content) happened back in February.

I just switched to using Jekyll instead of Wordpress for this site.

I’m still recovering from Maker Faire last weekend.

Over the past month, I’ve been working on a laser turret for the DefconBots autonomous robot competition this Summer.

I’ve been using the Dangerous Prototypes Bus Blaster along with openOCD to program/debug my LPC1769 microcontroller.

A few days ago, I found out that you can send video messages to people via Skype.

Soon after I bought my Kinesis Freestyle 2 Keyboard, I noticed that the media keys (next/previous song) did not work with Spotify on OSX.

After getting the gcc-arm compiler working with the mbed, I decided to take a look at my LPCXpresso LPC1769 development board.

Don’t want to read though this post?

If you haven’t heard about my ‘home automation’ project, you should probably read this first.

I’ve been neglecting my projects for a while, but I finally decided to stop being lazy and started working on them again.

I recently found out that the San Francisco International Airport (SFO) offers bike parking for up to 14 days.

I recently started working on a project that might require some Passive Infra-red (PIR) sensors.

The Wireless Friend Finder was my project for the Bring-a-Hack dinner after the 2012 Bay Area Maker Faire.

I finally decided to get a dedicated electronics workbench.

I finally managed to make a quick video of the build process for my wireless RGB LED controller.

I just spent several hours debugging my cc2500 radio libraries.

I’ve been working on my wireless RGB LED boards for a while now.

I recently migrated my blog from blogger to WordPress.

I received my PCB’s yesterday (From Laen at dorkbotpdx.org, of course!).

Here’s another quick update (with lots of pictures and a video!)

My current apartment has one of those ‘smart’ electric meters that can communicate with the power company directly over the power lines.

I managed to go flying last Friday after work.

This post is mostly about software, so I’ll keep it short.

So I wrote last week about getting UART working on the MSP430G2533 but having major problems with the SPI interface… I was so frustrated that I caved in and purchased a Salae Logic analyzer.

I haven’t been working on this project lately, but I finally got back to programming yesterday.

Here’s an even smaller update!

Here is a quick update on the project’s progress.

So I’ve started working on another project… This one includes microcontrollers and radios.

So I had a few days off work for thanksgiving… Most people usually visit their family during that time, but due to a late change of plans, I ended up doing something else.

I recently started experimenting some more with time-lapse videos while moving.

I have been working on a few projects recently.

A few months ago, I found out that my school offers a diving class.

I recently purchased a Casio EX-FH100 digital camera.

I’ve decided to actually write about what I’ve been up to in the past few years.

I still haven’t written about my Svalbard trip.

I am writing this in an internet cafe in Oslo… Svalbard was amazing!

Saturday August 7th My day started at 3:50am when I woke up.
