DIY: build your own oscilloscope

July 29th, 2014

Check out this cool FPGA project to make a DIY oscilloscope done for a school project. Nicely done!

We( Haolin and Joris ) built this oscilloscope last semester for a school project. The ADC chosen is a high performance differential ADC which uses Low-voltage differential signaling (LVDS). A FPGA is used to interface the ADC accounting for its properties such as high clock frequency, parallelism and differential inputs/outputs. The back-end software is written in QT with OpenGL libraries. This software supports oscilloscope and FFT functions.

PLIP August 2014: Soft Core Processor with ZPUIno / ZAP / Papilio

July 28th, 2014

Colin O’Flynn makes a cool video showing the ZAP IDE in action! Watch as he makes a custom PWM peripheral, adds it into the ZPUino Soft Processor, and writes C code to control it.

Jump to 37:10 mark to see it working! Full details at in August 2014 Issue of Circuit Cellar. Code is located as a link on that blog post.

Today Toaster Pictures

July 12th, 2014

While in China I worked with and bonded with a local group of Chinese Makers on a fun project called the Today Toaster. The Today Toaster connects to the Internet and captures the weather for the day and then toasts an image onto your bread to keep you up to date with the days weather.

We had a two day long hack session getting everything together and working and then attended an awe inspiring award ceremony at the People’s Hall, which is like the White House…

Here are pictures from the Today Toaster build, when I get a couple more minutes on a solid Wifi connection I will make a post about the People’s Hall!

I’m currently in Wuhan visiting the LinkSprite corporate offices and am set to get on a train to Shenzhen in a few hours. More to come soon!

Working on Today Toaster in US-China Maker Competition!

July 7th, 2014

I’m in China now working with a team of young Makers on a a very special toaster that prepares you for the day by toasting the weather forecast onto your toast! Using the Intel Galileo board and a connection to the internet it will get the latest forecast and then use an Arduino sketch to select the right pattern of burners to serve you up with a fresh and informative piece of toast! It’s been a blast so far and I’m thoroughly enjoying my time in China with my awesome teammates!

Here we are meeting for the first time – the Today Toaster team!


Here is the conceptual drawing made in the team building exercise.


Here we are tearing apart and modifying the toaster.
