Things You should Know Before Buy GPS

Published / by mimin

Garmin is one of the leaders in GPS technology that offers a range of cycling GPS aimed at different kinds of riders. The Garmin EDGE series has basic models that can track your time, speed, and distance, as well as advanced models that have features such as pre-loaded cycling specific maps and route navigation.

If you’re into cycling and would like to track your performance or capture data while you ride, a GPS cycling computer would be one of the gears you would want to have. Unlike a phone, the Edge GPS cycling computer works up to 8 hours without worrying about data or battery drainage. It also uses GPS/GLONASS satellites for fast and accurate location.

Given the number of Garmin Edge cycling GPS you can choose from, here are several things to consider which will satisfy your need.

For basic riders who simply want to get basic cycling data

Garmin Edge 20/25

The Garmin Edge 20/25 is easy to use and captures essential stats from your ride, including time, distance, speed, total ascent and location. It’s one of the smallest cycling GPS available today.

It has Garmin’s Auto Lap, Auto Pause and Auto Scroll features. You have the option to customise two display fields with up to three data fields per page and create course navigation using Garmin Connect.

Garmin Edge 25 is similar with Edge 20 but offers additional features that includes the following:

  • Smart notifications (displays email, text and other alerts when paired with your compatible phone)
  • Bluetooth Smart for uploading completed activities, and downloading rides/courses through Garmin Connect (not for Bluetooth sensors)
  • ANT+ sensor compatibility to track speed/cadence and heart rate
  • Garmin LiveTrack
  • Speed and Cadence Sensor
  • Compatible with Garmin Varia Rearview Radar

For those who want comprehensive ride data and smartphone connectivity

Garmin Edge 510

Garmin Edge 510 can measure the cycling metrics that most riders would want or need, such as distance, speed, ascent/descent and it gives the option of using a heart rate monitor, cadence and power meters using ANT+ compatible sensors.

You can create up to five different activity profiles which allows you to customise data fields and device settings based on cycling activity, such as training or racing. Simply swiping Garmin 510’s touch screen will set it up to show the data you need for that ride.

When you pair the Edge 510 with your smartphone and use Garmin Connect Mobile, you can get real-time weather conditions, use social media sharing and Live Tracking. Garmin’s LiveTrack, lets you invite others to follow your rides so they can view your live data on a Garmin Connect tracking page. The Garmin Connect Mobile app also allows you to wirelessly upload completed activities and download courses on your device.

For those who want advanced cycling data and smartphone alerts

Garmin Edge 520

As the upgrade to the Edge 510, the Edge 520 has all the features of the previous version but with a high-resolution colour display.

For those who want advanced training capabilities, routable navigation, and smartphone connectivity

Garmin Edge 810

The Edge 810 is the upgrade to the Edge 800 and offers the features available in the Edge 510. It lets your switch profiles during a ride just by swiping the touch screen just like the Edge 510 albeit in a larger screen. The touch screen is resistive, which means that even with wet fingers, or with gloves, it’ll still respond.

The big difference that Edge 810 has over the models mentioned above above is that it has built-in basemaps and is compatible with optional detailed street or TOPO maps, so it can guide your ride for touring where you might need onboard maps and navigation. Maps in the Edge 810 are routable, which means it knows that if you missed that turn on a particular street you can instead turn right on another street and loop back.

As with the Edge 510, Edge 810 also offers connected features through your smartphone, including live tracking, social media sharing and weather. Edge tracks the data and sends it to your phone using a Bluetooth® connection.

For who wants advanced training capabilities, routable navigation, and smartphone alerts

Garmin Edge 1000

The Edge 1000 is the flagship GPS cycling computer from Garmin. It has a robust 3-inch high resolution touchscreen which has an integrated light sensor to automatically adjusts for light conditions.

Where the Garmin Edge 1000 truly shines is that it offers the best in class mapping functionality and can give you street-level turn by turn directions. It comes with free detailed bike-specific maps which is based on the Open Street Map, a community sourced map set. With its Route Planner feature, you can create routes directly on the device using the map, POI and segments you’ve downloaded from Garmin Connect.

The Edge 1000 lets you pair multiple ANT+ sensors as you’d like (heart rate monitors, cadence and speed monitors, Vector power pedals) for as many bikes as you’d like. Just connect to the sensors you have enabled at the start of the ride.

You can also create training pages with up to 10 data fields and use various activity profiles for quick and convenient transitions when you switch your cycling activity, such as road, mountain biking or touring. To further improve your training and riding experience the Edge 1000 uses Garmin’s Advanced Workout and Virtual Partner functions.

As you’d expect with Garmin’s top of the range Edge device, you can pair Edge 1000 with your smartphone to enjoy the connected features with Garmin Connect such as live tracking, sending/receiving courses, social media sharing, and weather. Edge 1000 is the only Edge device that can use Wi-Fi.

Similar to Edge 520, you can also take advantage of following functionalities.

  • Smart notifications (displays email, text and other alerts when paired with your compatible phone)
  • Compatible with Edge remote control, VIRB action cameras, Varia bike radar and lights
  • Integration with Shimano Di2 electronic shifting (track your current gearing while you ride)

In A Nutshell

At the end of the day, the type of cycling GPS that you should get boils down to your preference. The Edge 20 and Edge 25 is a compact cycling GPS that does a good job of tracking your time, speed and distance. The Edge 510 gives you the basic needs to be a competitive cyclist.

All About Hand Chain Block

Published / by mimin

Hand operated manual chain hoists (also popularly known as a chain block or block and tackle) are a part of handy lifting equipment available in adaptable configurations; they are very flexible to the several alternative working circumstances and working environments including temporary and permanent installations

How to Safely Use a Hand Chain Block?

1. Handle and store them properly.

2. Check the block and all the other accessories before using it and also before placing into the storeroom.

3. For top hook suspension, utilize hooks that are fixed with safety catches, or intruding the hook, making sure the support fits without stinting into the seat of the hook.

4. Examine and make sure that the bottom hook will make a contact with its lowest point without operating the chain completely out.

5. For trolley suspension, make sure the trolley is properly set for the beam size.

6. Use safe suspension practices and follow the instructions very carefully for safely using the equipment.

Things to Avoid:

1. Don’t let it get exposed to chemicals, any acids, without asking the supplier.

2. Don’t drop, drag or throw it.

3. Without consulting the supplier, don’t replace the load chain with a longer one.

4. Don’t use excessive effort to make it work.

5. Don’t let the grease or oil to come into contact with the brake.

6. Don’t let it expose directly to the water spray, elements, steam etc without confirming the supplier.

How to Select the Right Unit?

Today, the hand chain block is available in a large variety of abilities and with different types of suspension. Choose the block to be used and prepare the lift by keeping the following things in mind-

  • Kind of suspension – trolley, hook, etc.
  • Class of use, capacity and range of lift.
  • They are designed especially for vertical lifting only.
  • Discuss with the provider if the block is to be used in areas of high risk, exposed to the water, elements, steam etc, with dangerous substances, like chemicals, or acids, or intended to use in extremes of temperature.

How to Store and Handle Them Carefully?

  • Don’t keep the damaged piece back to the storage. They should be clean, dry, and kept safe from corrosion.
  • It should not be thrown, dragged, or dropped to the floor.
  • Store them by their chief suspension with chains apparent on the ground, the chains may be tied together to facilitate this. It’s recommended that all the non-portable blocks kept outdoors must be covered and saved from corrosion.
  • Don’t galvanize or subject the chain, or any other weight bearing parts, to any other covering process without consulting the supplier.

How to Maintain Them?

Go through all the instructions given by the supplier, especially the maintenance instructions. It’s important to keep the load chains well-lubricated and periodically examine the operation of the brake. Brakes should be kept free of grease, oil, etc. Without consulting the supplier, don’t replace the load chain.

Regularly examine it and, if any, defects are found, immediately give the block to an experienced person for detailed examination. Using it in damaged condition can not only make the condition of block worse, but also harm the person.

Interesting Fact About Electromagnetic Compatibility

Published / by mimin

Electromagnetic Compatibility or EMC is assuming increasing importance in today’s device intensive world. This means, question of radiation and interference to critical electronic equipment or their components is more of a risk today than it ever was. Another important fact to consider is that a number of devices that can malfunction with electromagnetic radiation operate in highly sensitive environments. Airplane cockpits and hospitals are just two examples where any interference to such equipment can result in some serious risk to human lives. There is little doubt that a comprehensive knowledge of EMC is absolutely essential for manufacturers and designers of products with components that cause such interference or that can be impacted by it. Equally important is the knowledge of how a shielded enclosure can safeguard their product and the environment where it will work.

Factoring in EMC at Product Design and Development Stage

It is critical to consider EMC right from the stage when the product is on the drawing board. At this stage, many designers and manufacturers tend to pay attention mainly to the physical attributes and the functionality of the final product. But, will it perform efficiently when deployed in its environment? Will other devices impair its functioning? Or, will it disrupt the working of other devices?

For example, consider a wireless, remote-controlled light that is ideal for operating room conditions. If this product emits electromagnetic interference (EMI) that causes critical life support equipment or vital signs monitoring equipment to falter, no surgeon would be willing to risk giving it a trial at his hospital. Considering these factors at the design and development stage can save the manufacturer money, time and production costs while ensuring that the result is a safe and viable product.

Choosing the Shielding Material and Type with Care

Electromagnetic shielding is often done with the dual objective of blocking both EMI and RFI (radio frequency interference).- A number of materials, mainly metals, are used commonly for this purpose. For example, you may find copper, aluminum, nickel or steel alloy in a shielded enclosure. While all of these are effective, many manufacturers believe that an alloy made from nickel, copper, iron and molybdenum offers the most effective shielding.

The manner in which these metals are used is also important and there are differences in this aspect too. Some use solid sheets, while others prefer perforated sheets. Coatings and screens of EMI resistant materials are also quite common. The type of material to use and the form in which it is used are both factors you should consider well before the product reaches the final production stage. You should test a prototype of the EMI shielded product in actual working conditions to verify that the shielding is holding up as expected, before the product goes out in the market.

The variety and range of shielded enclosure options make it easy for you to find the perfect one for your product. Make sure to invest your resources in this task at the right time in your production cycle and you can have a truly successful product on your hands.

How To Keep Your Cooling System Cool

Published / by mimin

Then, homeowners realize that the cooling system they just installed makes more noise than they like. These tips will help make sure that everyone can still hear the television over top of the fans in the cooling system.

Anti-vibration mounts

When the fans get going, they are going to vibrate at least a little bit. It is not a matter of whether they vibrate, but a matter of how to keep them quiet. If people hear a vibrating noise, anti-vibration mounts are the way to go. Anti-vibration mounts are usually made of rubber, and work exactly like regular ones. The rubber that anti-vibration mounts are made of helps prevent the vibrations from reaching the wood or metal to prevent that annoying noise from disrupting everyone’s favorite show.

New fans

After installing anti-vibration mounts, there may still be noise from the fans themselves. Anti-vibration mounts will only help with noise from that motion, and that will not be enough to quiet a noisy fan. Not all fans are designed to be quiet. Consumers are encouraged to keep in mind that there is no such thing as a silent fan, but there are certain products that are designed to be as noiseless as possible.

Taking the time to shop around to find a fan that is as quiet as possible will be well worth the time when everyone can hear what is going on in the game instead of the constant whirring noise of fans.

Include plenty of space

There needs to be enough room in the media cabinet for the fans themselves, and then added room above or below components of the cooling system for air circulation. Most people do not realize this if it is their first time making their own cooling system. Then, when they are finished, they realize their cooling system sounds like a miniature wind tunnel.

Guaranteeing that there is enough room in the cabinet for air circulation will help cut down on unnecessary noise.

More fans

If the electronics in the cabinet are so hot that a fan has to be turned on high, picking up a few more fans is probably the way to go. Simply install them, and then turn all the fans on low. Doing this will be much quieter than using less fans and turning them up on high. Including more fans in the cooling system also guarantees that there will be plenty of air circulation in the cabinet.

Usually, when homeowners install more fans to cut back on noise, they discover that there is more air circulation in the cabinet, even if the fans are all on low. Then, they don’t have to turn them on as often either.

Installing a cooling system for the first time can be a bit challenging, especially when homeowners find themselves struggling to keep the cooling system quiet and their electronics cool at the same time. Thanks to these tips, homeowners undertaking this project will no longer wonder if they are going to be stuck with overheating electronics or a noisy cooling system. Their electronics will run quieter and stay cooler and their cooling system will barely be heard, if at all.
