Seeed Fusion OPL Enables Complete PCB Manufacture and Assembly in One Week at Low Cost

1

What is the Seeed OPL?

The Seeed Fusion Open Parts Library or OPL is a tailored catalog of over 600 carefully selected components available for use in Seeed Fusion’s PCB assembly service. From capacitors and connectors to ICs and displays, these parts are always in-stock and guaranteed to be cheaper than externally sourced parts. By using these components in Seeed’s PCBA service, you will save time and money and at great convenience.

More Reliable

Components from the OPL are sourced from Seeed’s long-term partners. They are tried and tested in Seeed’s own products and undergo the same strict quality control procedures. And since there is always stock, if one part is defective it can easily be replaced. Arguably this is better than outsourcing from a reliable distributor such as DigiKey since outsourced parts cannot be easily replaced and may have been damaged while traveling halfway across the world.

More Convenient

The Seeed OPL was designed for convenience and simplicity. Seeed partnered with PCB design giants Eagle and KiCad to produce the Seeed OPL component libraries, so you can just download the packages and start designing. The resulting design is guaranteed to be compatible with the Seeed Fusion OPL and PCB Assembly service, so no more wasting hours checking availability and compatibility with suppliers.

There is also plenty to choose from; the Seeed OPL does not just include passive parts but many that are utilized in Seeed products and more. Hand-selected by our engineers, the parts are decided on based on customer popularity and feedback. Most recently, in response to the increasing interest in IoT, we introduced Particle’s popular P0 and P1 Wifi modules into our stock.

Faster

Typically, the lead time for PCBA is 25 working days. That is over a month before you can begin testing the design and make amendments if necessary. For some, that is much too long. But by sourcing all parts from the OPL, the lead time can be reduced to as short as one week.

When a PCBA order is placed, Seeed will simultaneously begin PCB manufacture and order the parts. Both the PCBs and parts are needed to begin assembly, assembly itself can be completed from 8 hours when all the materials arrive. The long lead time for standard PCBA is a result of the long import procedures which cannot be rushed. But since the OPL parts are always in stock, using these will effectively reduce the lead time for parts procurement to zero, speeding up PCBA and allowing greater control over the overall lead time.

Cheaper

Since Seeed OPL parts are purchased in bulk from trusted partners, the cost per component is guaranteed to be significantly lower compared to buying them in small handfuls, and you won’t need to worry about delivery costs. These cost savings are passed on directly to customers. What’s more, this month only, Seeed Fusion has waivered the cost of over 400 parts from the OPL, so you can use them completely free, no restrictions applied.

The Seeed Fusion OPL has already helped many of you reach critical deadlines and slash costs, and we hope it can continue to do so. We would love to hear if you have any new additions you would like to see in the OPL or other suggestions regarding any of our services. Please drop us a message at fusion@seeed.cc. The library and Fusion as a whole is continuously being enhanced thanks to feedback from you.

Don’t forget, Seeed Fusion is currently holding huge Spring sales across PCB and PCBA services. For the last three days, get 10% off PCB orders, $50 off PCBA orders and over 400 OPL completely free!

The 2018 Hackaday Prize has launched

The Hackaday 2018 Prize has launched

The 2018 Hackaday Prize has been announced. This is the fifth contest of the annual Hackaday Prize series and is jointly sponsored by Digi-Key and Supplyframe. This year’s challenge to the hardware hackers across the globe is to “Build Hope” through open source hardware projects. Over the past 4 years, the Hackaday Prize contest has already given away nearly $1 million to the innovative makers who contributed towards building awesome stuffs to make this world a better place. This year has following 5 themed challenges that run in series:

    • Hardware Design Challenge: 3/12 – 4/23
    • Robotics Module Challenge: 4/23 – 6/4
    • Power Harvesting Challenge: 6/4 – 7/16
    • Human – Computer Interface Challenge: 7/16 – 8/27
    • Musical Instrument Challenge: 8/27 – 10/8

      The Hackaday 2018 Prize has launched

      The Hackaday 2018 Prize has launched

The first round of the competition is the “Open Hardware Design Challenge,” where entrants are encouraged to design the boldest plan they can dream up. Prototypes are not necessary for this challenge – only pictures, charts and theory are required. The Open Hardware Design Challenge kicks off today and runs through April 23.

The remaining rounds are the “Robotics Module Challenge” (April 23-June 4), “Power Harvesting Challenge” (June 4-July 16), “Human-Computer Interface Challenge” (July 16-Aug. 27) and the “Innovative Musical Instrument Challenge” (Aug. 27-Oct. 8).

“We’re excited to partner with Hackaday for another year of challenging inventors to be curious, creative and determined. The Hackaday Prize contest aligns with Digi-Key’s vision to encourage and enable innovation in technology that will solve problems and advance civilization. With the amazing projects we’ve seen in previous years, we can’t wait to see what the entrants create this year, ” said David Sandys, director, Business Ecosystem Development at Digi-Key. 

 

The top 20 entries from each challenge will win $1,000 and be considered for the Finals Round. The top five finalists, including the Grand Prize winner, will be announced at the Hackaday Superconference taking place Nov. 2-3 in Pasadena, California. The Grand Prize winner will be awarded $50,000 and considered for a residency at the Supplyframe DesignLab in Pasadena, California. The second-, third-, fourth- and fifth-place winners will receive $20,000, $15,000, $10,000 and $5,000, respectively.

 

 

In addition to cash prizes, participants will compete throughout the competition for most impressive, outlandish and otherwise notable projects. Although there is no cash value associated with these accomplishments, they do come along with bragging rights. Examples of possible Achievements include the Diva Plavalaguna Achievement (most unexpected musical instrument), the Sonic Screwdriver Achievement (hacks that seemingly do everything) and the Ender’s Achievement (most incredible student submission).

The official rules and other details about the 2018 Hackaday Prize can be found at the Hackaday Prize page.

Arduino Pong clock

The 2 players automatically win and lose so their scores show the hours and minutes. It is based on a clock by Nick Hall.

This is the 2nd version of my clock and now displays temperature in slide mode and also has a timer in normal mode. The 1st version can be found here Pong Clock Mk1 instructable

The clock has lots of different display modes to choose from:

Pong Clock, Large Digits,Time written in words, e.g. “Ten Past Twelve”, Time and date with seconds,Time and date with seconds and a slide effect,

Options-12/24 hour option, Brightness option, Random clock mode option (changes the display mode between Slide with temp and Pong see bottom for details), Daylight saving option to add an extra hour.
