Happy 6th Anniversary

Happy Birthday, Seeed!

It was the best of times, it was the worst of times,
it was the age of wisdom, it was the age of foolishness,
it was the epoch of belief, it was the epoch of incredulity,
it was the season of Light, it was the season of Darkness,
it was the spring of hope, it was the winter of despair,
we had everything before us, we had nothing before us,
we were all going direct to Heaven, we were all going direct the other way.

– A Tale of Two Cities

In the past year, We had grown a lot while gaining media attention.

  • a 100+ team into a big family with 180+ members.
  • we occupy the 4th and 5th floor, the STU is move to 2nd floor
  • a fresh new look of website
  • lots of new equipments for our mini tech space
  • introducing seeed.cc
  • updating chaihuo 2.0

We still push forward open hardware and maker culture.

  • In April, we co-organized and sponsored the Maker Faire Shenzhen 2014, which is featured with additional conference – “Innovate with China”
  • In May, we attended Maker Faire Bay Area, joining MakerCon
  • In July, we went to Maker Faire Hannover
  • In August, we designed high tour shenzhen, guiding Japanese makers get to know the factories, electronic market and Haxlr8r.
  • In August, we supported OHSummit2014!
  • We held two local workshops every month.

Thank you so much for the great support, dear customers, partners, cooperated designers, distributors and many others in the open hardware community. Without you, Seeed won’t be able to go far.

Thank you for witnessing Seeed’s growth in these 6 years.

DSO Touch Official Leak – Test

This is the final episode of DSO Touch Official Leak Series, cause I have to wait for the sample until mid Sep, the only 2pcs of DSO Touch are sending to Petteri Aimonen & Tobias Schramm.

The input signal for distortion test is sine wave, ranging from 10kHz to 20+ MHz. We judge the level of distortion by

  • FREQ measured
  • VPP measured
  • Shape of wave

Let’s go.

WP_20140827_034 WP_20140827_035 WP_20140827_036 WP_20140827_037WP_20140827_039

Result – DSO Nano V3 with BenF firmware.

  • 10 – 40kHz: everything seems ok
  • 50kHz: the measure FREQ is 44.9 kHz (acceptable), a discontinuous pattern begins
  • 60kHz: went wrong

WP_20140827_010 WP_20140827_013 WP_20140827_014 WP_20140827_015 WP_20140827_017 WP_20140827_018 WP_20140827_019 WP_20140827_023WP_20140827_021WP_20140827_024

Result – DSO Touch Beta v0.1

  • begins @ 40kHz: everything seems ok until 100kHz
  • 110kHz – 130kHz: a error in FREQ, but the wave on screen and VPP is right
  • 160kHz+: went wrong

WP_20140827_026 WP_20140827_027 WP_20140827_028 WP_20140827_029 WP_20140827_030 WP_20140827_033

Result – DSO Quad

  • begins @ 21kHz: everything too easy for it
  • 100kHz – 800kHz: ok
  • 3MHz+: the shape becomes unstable from this moment.

We can tell the difference from this simple test. DSO Touch is regarded as an updated DSO Nano. With much wanted improvements on performance, we hope a better updated firmware from community.

Updated: Beta Program of DSO Touch

DSC00761

  • Beta 1st: 2 pcs of DSO Touch, late Aug
  • Beta 2nd: 10 pcs of DSO Touch, mid Sep
  • Beta 3rd: not exist yet
  • Firmware Preview: Sep
  • Pre Order: 50-100pcs, Oct

We receive 150+ request by the deadline, which come from a variety of backgrounds and countries. We saw lots of familiar names on the list, making us quite difficult to choose.

Thx all guys who sign up! Since the test plan is limited, you can get prefered pre order and coupon once the first batch is produced.

Here are the 1st lucky birds – shipping begins next week

  • Petteri Aimonen (aka jpa)
  • Tobias Schramm

Here are the 2nd testers (7 left) – shipping begins mid Sep

  • BenF
  • tormod
  • Mark Bauer

We hope to work with you to improve the usability/UI/functionality of new gadget. SeeedStudio will help you share your knowledge and experience using DSO on blog, from average usages in homebrew projects to hacking the DSO.

We reviewed your message carefully.

Chris McKernan wrotes:

The biggest problem with the Nano and Quad style portable oscilloscopes is that the User Interface lacked intuitive functionality.  It was always difficult to change settings ‘easily’.  In most cases the idea of a pocket sized test scope is great, but they always seemed to have large faults.  My use would be testing where it needs to be tested, being used for Atmel (or arduino) board designs/Field work.

That’s what I choose BenF’s firmware for DSO Nano, it’s much more simple. We hope there’re 3rd firmwares better than the original one for DSO Touch!

We reserved one for Mark Bauer, who is a university teacher of Electrical Engineering at the of Nebraska, we’d like to support education by providing affordable electronic equipments.

We will announce the final 10 testers next weekend, the sign up form is still valid for the next term (you don’t have to sign up again, we’ll go over it again then).

DSO Touch Official Leak – Industrial Design

IMG_7216IMG_7218

A short review of DSO Family on industrial design.

IMG_7207IMG_7208 IMG_7209

The panel of DSO Touch is as big as DSO Quad. Due to the touchpad area, the screen of DSO Touch is smaller. But don’t worry, Touch uses a pop up menu system instead of using a fix menu system, which enables the same user experience.

IMG_7212 IMG_7213 IMG_7214

Very close result. You could see a little improvements on both the hardware inside and the enclosure outside.

IMG_7221 IMG_7223 IMG_7226

Wide and Slim, that’s how DSO Touch is designed to be the ultimate killer of electronic hobby and education.

We know you could expected it. Please focus on the next official leak – hands-on video. You can rss our blog or subscribe our newsletter to get latest news on it.

DSO Touch – No More, No Less

IMG_6822-001

DSO Touch is designed to fit most of the hobby electronic experiments scenarios.

Here are the main features/specs of DSO Touch with a comparison of DSO Nano/Quad, and how it is designed.

Display

the same resolution as Nano: 320×240, making it portable is still the main feature of DSO series. The TFT screen features nice effect with soft color, which is rare on equipment under 100 bucks.

Performance

Virtual broadband improves from 2kHz(DSO Nano v3) to 2MHz, What’s more, the max sampling rate rises from 1MSa/s(DSO Nano v3) to 10MSa/s. Which means it handles most of the problems you meet. Have you ever imagined you can have a 10MSa/s DSO in such size that it could slip out of your pocket? That’s how we did it.

Channels

As we all know, there’s one analog channel for DSO Nano, two analog & digit channels for DSO Quad. Since the digit channels are rarely used, they are cut off to leave space for DSO Touch. You can measure two signals and compare the difference now in real time!

The sampling storage depth is up to 8K, the probe is replaced with Mueller MCX Probe (similar to DSO Quad), making it the fittest with the power-up performance of DSO Touch.

Touchpad

A revolution which is much more difficult than the industry design and user experiences of DSO Nano/Quad. The gesture based control command is more human friendly, you can swipe to get the option as fast as you can.

NO MORE, NO LESS

We hope the human-centered design philosophy of DSO can really help in your daily life, replacing the old fashioned instruments from your workbench. Electronics can be arts, by presenting simple, elegant, practical and people-oriented designing.
