We've been using the updates on our Kickstarter to demonstrate how the Tsunami works and what you can do with it. In the latest update, we demonstrate using it to find the frequency response of an audio amplifier. Check it out!

Along with Sir Terry dies the future of an entire world; disc shaped, and travelling through space on the back of four elephants themselves perched on the back of a giant turtle, as well as countless other worlds he might have invented and entertained us with if death hadn't stopped by for a chat so soon.

I met Mr Pratchett once, amongst a legion of fans when he gave a talk and signing in Christchurch. He struck me as witty, generous, and unfailingly patient, as he massaged his hand between signing countless books. Despite the lengthy line, he still found time for a few words, and was attentive enough to stop me absent-mindedly closing the cover of the book he'd signed before the ink could dry.

Terry Pratchett was one of my favorite  authors; every new outing with a new Discworld book was a much anticipated experience, over too soon. I'm deeply saddened that's something I'll get to experience at most one more time, and even more deeply saddened that I'll never be able to thank him in person again for everything he's done to make so many peoples' lives better and brighter.

Goodbye, Terry Pratchett.
Discworld author Sir Terry Pratchett dies at his home aged 66, eight years after he was diagnosed with Alzheimer's disease.

Yes, I was saddened too Nick.  Despite never having read any of his books he struck me as one of life's characters.

We're taking a huge 50% off Minishifts on @tindie until Friday! This is the cheapest they'll ever be, so be quick! Use code 9E07E62 to get the discount.
The Minishift is a chainable, scrolling LED matrix display you can control over USB or from a microcontroller This listing is for a pack of 9 minishifts with an enclosures and USB interface. You might also want to check out the single pack or 4-pack option with enclosure instead. The Minishift is a compact and affordable 8x8 LED matrix display that speaks SPI, and can be driven from any microcontroller platform, or with an optional interface boar...

Fun, but that screeching sound is incredibly annoying.

Rigol's scopes in averaging mode look really funky.

We’ve just launched our next product, the Tsunami, and it’s up on Kickstarter!

The Tsunami is a powerful and flexible signal generator built on the Arduino platform. It’s the best way to get started experimenting with analog signals, and a great tool for a huge variety of tasks, too.

The tsunami takes the versatile processor behind the Arduino Leonardo, and combines it with a Direct Digital Synthesis chip, which makes generating analog signals incredibly straightforward. It also has flexible input and output circuitry, and an easy to use software library, to make working with analog signals as easy as blinking an LED.

Glad you like it! If you back, you won't get charged until after the 6th, though. ;)

I should disclaim, it's not an oscilloscope: for signals faster than the AVR's ADC can manage, it can detect peak amplitude, detect zero crossings, and measure relative phase, but it can't reproduce the whole waveform.

There are schools in the wealthiest parts of Los Angeles where the vaccination rate is on a par with that of South Sudan

Recently, a musician, Kim Boekbinder, ran a kickstarter promising to write a 1 minute song based on 2 words of your choice. I commissioned one for +Juliet Gibbons . My two words were "Darth Cuddles"; here it is.

Story
Tagline
I'm a geek and software engineer living in London, England.
Introduction
I'm a proud Kiwi, originally from Christchurch, New Zealand, but I've spent the last 5 years or so living overseas - first in Dublin, Ireland, then in Sydney, Australia, and now in London, England.

I enjoy making things, cycling, and boardgames. I also enjoy my job, which makes me pretty lucky, I think.
