6 Tips to Reduce the Risks of Hardware Entrepreneurship

In this case, you probably need to start from scratch: go deep into the market, understand the demand, and run through the supply chain.

Judging from my personal HE Tuber actual product experience: if you do not have a unique advantage or do not have matching resources in the market, the probability of failure is extremely high.

No matter how perfect the product is, no matter how sure you are that you will be a huge success.

You should always strive to minimize risk.

Of course, you can't completely eliminate risk.

But risks can be minimized, investments protected and chances of success increased.

The odds are generally better for hardware startups.

As a start-up, you need to build every possible advantage to help you achieve your financial goals.

Here are six ways you can gain a competitive advantage when bringing new hardware products to market to reduce risk and increase your chances of success.

Hire multiple independent engineers

When it comes to developing electronic hardware products, one of the best ways to reduce risk and increase your chances of success is to hire at least two engineers:

An engineer comes to actually develop the electronics;

Another independent engineer comes to review the design;

Then prototypes are produced.

No matter how good an engineer is, mistakes are almost always made when designing anything complex.

You should always strive to gather as much feedback as possible.

Design reviews are key to preventing mistakes. One thing is certain:

Any hardware product developed by a large company is reviewed by multiple engineers.

For startups, if you have the ability to review.

This will undoubtedly save a lot of personnel costs and be more efficient.

Start with small batches

Your first priority is to get your product to market as quickly as possible and as cheaply as possible.

while minimizing risk.

Risk is something you should focus on before your product achieves significant sales success.

Take the smart lock product that I was personally responsible for as an example. At that time, market verification had been initially completed.

Then they started to build assembly plants and made a lot of investment in mass production, and the capital chain was almost broken.

That is, if you go bankrupt before getting your product to market.

Then there is no point in focusing on maximizing profits.

Use electronic modules

One of the best ways to reduce electronics complexity, and therefore risk, is to use proven electronic modules for certain functions.

For example, if your product requires wireless functionality, you will need to obtain a radio certification license from your region or country.

Certification usually takes a long time, and some also charge certification fees.

For example, in China you need to obtain radio certification SRRC.

For example, when I personally used Bluetooth and WiFi when making products in the early days, I needed to undergo SRRC certification at this time.

At the beginning, because I was not clear about the specific testing standards, I spent about a month and visited the certification agency three times.

Electronic modules are independent components designed to perform specific functions and are electronic circuits that are easily integrated into other products.

For example, some networking modules of Tuya and Espressif.

Of course, the reality is that most products still require some custom circuit design.

This is because using modules entirely to make products will greatly increase the unit cost.

Secondly, if your product is very small.

For example, in wearable technology, the module size may be too large, making it impossible to use modules for design.

Make full use of manufacturer resources

Most manufacturers have some resources that include assistance with design, engineering, 3D modeling, and prototyping during the product development process.

They may also connect you with suppliers, such as component and packaging suppliers.

If you have a viable product and maintain consistent sales.

They can also provide you with billing terms, such as allowing you to pay within 30 to 90 days after shipment, etc.

This will greatly improve your cash flow and increase your competitiveness.

When you work with a manufacturer, they generally allow for amortization of tooling costs.

Build a customer base before building a product

You need market feedback from day one.

Don’t wait until your product is ready to hit the market before you start thinking about how to sell it.

You need to gain some market traction as quickly as possible.

Hardware startups face serious challenges, and you can reduce risk and increase your chances of success by exploring these strategies.

This has two benefits:

First, you will be able to get quick market feedback from potential future customers;

Secondly, once your product is available for sale, there will be a large number of customers ready to buy your product.

Pre-sell your products

People may praise your product.

But all the praise means nothing unless it's accompanied by sales.

You need to pre-sell your product and test it in the market.

Getting feedback quickly can let you know whether the product has value and whether it's worth spending more of your resources.

Bluetooth headset to do SRRC certification

Bluetooth headset to do SRRC certification

The SRRC certification is a must for any Bluetooth headset that wants to be sold in China. But what exactly is this certification, and why is it so important? In this blog post, we'll explore the SRRC certification process and what it means for Bluetooth headsets. We'll also provide some tips on how to make sure your headset is SRRC-certified. By the end of this post, you'll know everything you need to about SRRC certification for your Bluetooth headset.

What is the mark of SRRC certification?

SRRC certification is a compulsory certificate for products that use the 2.4GHz band in China. The full name is "2.4GHz Short-Range Radio Transmission Equipment Certification". In order to obtain SRRC certification, manufacturers need to apply to radio management authorities and testing organizations recognized by the Ministry of Industry and Information Technology for testing and certification and pass the test to obtain a certificate.

The mark of SRRC certification is a logo with the letters "SRRC" in it. This logo must be displayed on the product or packaging, as well as in any promotional or marketing materials for the product.

Products that have obtained SRRC certification are allowed to be sold in China.

The necessity of applying for SRRC certification

The SRRC (Short-Range Radio Communications) certification is a must for any Bluetooth headset that is to be used in China. The certification, which is granted by the China Ministry of Industry and Information Technology, ensures that the device meets certain safety and quality standards.

Not only is the SRRC certification a requirement for import into China, but it is also necessary for the sale of any Bluetooth headset within the country. This makes sense when you consider that most people use their Bluetooth devices in close proximity to their heads and face, and thus potential health risks are involved.

So if you're looking to buy or sell a Bluetooth headset in China, make sure that it has been certified by the SRRC. It's the only way to be sure that you're getting a safe and high-quality product.

SRRC Certification Application Procedures

In order to obtain SRRC certification for your Bluetooth headset, you will need to submit a certification application to the appropriate authorities. The application must include all relevant documentation and fees as required by the SRRC. Once your application has been reviewed and approved, you will be issued a certificate which will allow you to sell your product in China.

ZHONGREN is a professional ccc certification china, we provide you with one-stop service throughout the process and escort the success of your product certification because we have established a good relationship with Chinese certification bodies and testing laboratories. Our team provides high-quality certification services for customers. It can make the whole authentication process go smoothly.

New Post has been published on https://www.updatedc.com/2019/01/08/dji-smart-controller-for-the-mavic-2-pro-and-mavic-2-zoom/

DJI Smart Controller for the Mavic 2 Pro and Mavic 2 Zoom

The DJI Smart Controller for the Mavic 2 Pro and Mavic 2 Zoom drones has been announced at CES. The Smart Controller features an ultra-bright display screen and optimized controls and allows users to fly the Mavic Pro 2 and Mavic Zoom without using a smartphone or tablet.

DJI Smart Controller

  The DJI Smart Controller features a 5.5” screen built into the controller itself. It has been designed so that you no longer need to connect to a mobile device. This makes the whole process of getting your drone up in the air a lot quicker and easier. It can be paired with DJI’s newest drones including Mavic 2 Zoom and Mavic 2 Pro which use DJI’s OcuSync 2.0 video transmission system. The DJI Smart Controller supports automatic switching between 2.4 GHz and 5.8 GHz, reducing the influence of environmental interference on drone operation and image quality. This also ensures reliable long-range transmission at distances of up to 8 km.

Users can take advantage of its compact, highly portable design that has been optimized for use in direct sunlight. The ultra-bright display has an output of 1000 cd/m2, twice the brightness of standard smartphones. The brightness can be manually and automatically adjusted. When Auto mode is enabled, the DJI Smart Controller will automatically adjust its brightness using a built-in light sensor, making it optimal for the human eye according to the surrounding environment.

The DJI Smart Controller comes with a built-in microphone and speaker for expanded options such as live streaming. It can also playback video through the HDMI port at 4K 60fps with H.264 and H.265.

A customizable Android dashboard supports DJI GO 4, DJI Pilot, along with various third-party apps such as editing programs. The DJI GO 4 app also touts several new features including SkyTalk, that allows pilots to live stream the drone’s camera feed to social channels including Facebook, Instagram, and WeChat.

Another new feature is DJI GO-Share which easily transfers imagery from the Controller to your mobile device. The DJI Smart Controller brings a new level of reliability when flying, with 2.5 hours of battery life and the ability to operate in adverse temperatures as cold as -4°Fahrenheit and as hot as 104°Fahrenheit.

What is interesting is that users can download third-party apps through the built-in browser or install APK files from a microSD card. (DJI will not be liable for any permission or safety issues resulting from the use of third-party apps. If an installed third-party app prevents you from enjoying optimal use of your controller, DJI suggests you remove the app or restore the controller to the original factory settings.)

Price and Availability

The new Smart Controller will be available for purchase beginning in early 2019 for the retail price of $649 USD. Combination packages of the Smart Controller with Mavic 2 Pro and Mavic 2 Zoom will be available as well.

Is it worth the high asking price?

The Smart Controller looks to be a great idea, but to me, it seems extremely pricey given the fact it is going to cost almost half the price of a Mavic Pro 2 or Mavic 2 Zoom. What do you think? Let us know in the comments section below.
