Advantages of Buying a Pit Bike Over Traditional Japanese Bike

Published

on

Pit bikes became popular 5-6 years ago and flooded the market. They are still popular today because they provide several advantages over buying a traditional Japanese bike. These factors will always allow Pit bikes to remain a strong force in the low end market.

These advantages are:

1. Price

2. Entry level into motocross for the beginner

3. Spare parts are real cheap

4. Most Parts are generic

With the average 125 Pit bike costing $600-$800 for a good quality model which can take up to 80kg weight, pretty much any teenager can afford this. The equivalent in a Japanese bike would be a 90cc which has no where as much power and the parts cost an arm and a leg.

This is a great opportunity for Newbie motocross enthusiasts who want to try the sport of motocross.  They can ride in the import class with a total investment under $2,000 to get started. This would include, Bike, Helmet, pants, jersey, Boots, gloves, goggles etc. You no longer need to spend $5-7K to get started. In fact the total price to get started in pit bike racing is still less than the cost of a Japanese bike alone.

Spare parts are cheap as chips. Because of the market and economy the way it is right now you can actually buy a 2nd Pit bike off eBay and strip it completely for parts at a faction of the cost it would cost for a Japanese Bike. Obviously Japanese Bikes are higher quality but Dollar vs. value Pit bikes will always come ahead.

95% of Pit bikes are made in China. The Chinese, in all there wisdom copy the same technology from each other instead of customizing the parts like the Japanese which means 99% of Pit bikes either bought from different sellers or different brand names will fit generically. I.E Plastic fairings, Fuel tank, rims, Tyre’s, forks, frame etc.

So if you are considering buying a China Pit bike it basically comes down to this. You are buying a cheaper quality bike compared to Japanese but for the price and application you are using the bike for, the investment is worth it.

Check out the leading brands in the market like Motovert, Puzey, Terra Moto. I suggest spend that little extra and get the better quality models which will still be 1/4 of the price of the Japanese bike. You can buy 4 Pit bikes for 1 Japanese Bike. You can’t lose.

The Original R4 Brand DS Card

Published

on

By

1.1) DS Card (Pic)

A DS Card is an emulator device that can be used to play homebrew games on the Nintendo DS and Nintendo DS Lite. It comes in the size of an original DS game cartridge and is inserted into the DS via the Slot-1 of the Nintendo DS console. There are many brands of DS card made by different manufacturers such as the R4, DSTT, EDGE DS and many others.

1.2) DS card components

For a DS card to work, it will need three component: The DS card itself, a micro SD / SDHC card and the DS card firmware.

The firmware is basically the software part of the system. It is a program that allows a DS card to run homebrew application on the Nintendo DS console.

The DS card is basically the hardware part of the system. It contains the Integrated circuit (IC) and various other hardware component that allows the DS card the act as a physical adapter to interact with the Nintendo DS console.

The micro SD is the memory of the system where the firmware and homebrew appication are stored. It is basically the RAM and hard disk space of the system. The micro SD can come in 2GB, 4GB, 8GB, 16GB and 32GB. Micro SD for 4GB and above are known as micro SDHC (Secure Digital High Capacity).

1.3) Getting a DS card to work

The first step to get the DS card to work is to get the DS card firmware. This firmware may sometimes be provided in a disc but most likely nowadays to be available for download from the DS card manufacturers site or from the reseller site (like us -> NDS-Gear). The DS card firmware is usually in a .zip or a .rar file, which need to be unzipped (or unrar) using the WinZIP or WinRAR program.

The next step is to transfer the unzipped DS card firmware and homebrew applications that you would want to play on the Nintendo DS console from the computer into the micro SD. To do this, you will need a USB-micro SD adapter. Insert the micro SD into the USB-micro SD adapter. Insert the USB-micro SD adapter into the USB port on the computer. The computer will now detect an external memory drive which is the micro SD. Drag and drop all the DS card firmware and homebrew application into the root directory of the micro SD. The transfer of the DS card firmware is now completed. Unplugged the micro SD from the computer.

The micro SD can now be inserted into the micro SD slot on the DS card, which is usually located on the top corner of the DS card. The DS card is now a fully functioning system and can be inserted into the Nintendo DS or Nintendo DS Lite console. Turn on the power on the Nintendo console and the DS card is now working and the user can start playing homebrew appicaion that they have transfer onto the Nintendo DS console.

1.4) DSi card

A DSi card is similar to the DS card except it was created to work on the new Nintendo DSi console. DS cards can only work on the Nintedo DS and Nintendo DS Lite console. DSi card can work on all three Nintendo DS consoles (DS / DS Lite / DSi).

2) What is an R4?

2.1) Introduction

R4 is the most popular brand name for the DS card. There a 30+ brand of DS card that calls themselve R4. On NDS-Gear, we sell 2 out of 30+ of these R4 brands, the R4v2 (R4DS) and the R4 SDHC.

2.2) R4v2 (R4DS)

2.2.1) History of R4v2 (R4DS)

The R4v2, also known as R4DS, is the original R4 brand DS card. R4DS stands for ‘Revolution for DS’. The R4DS is one of the first superior DS card on the market as it can automatically boot itself on the Nintendo DS console without the need a PassMe Device (type devices are inserted into the DS slot and trick the DS into allowing unsigned DS code to run from the GBA cartridge slot in full DS mode). This made the R4DS cheaper, superior and very popular compare to other DS card on the market when it was released in early 2007. It was considered to be one of the best DS card when it first came out in 2007. Because of its popularity, many other manufacturers start making clone copies of the R4DS and also naming their product ‘R4’, giving rise to the 30+ brands of R4.

The R4DS change its name to R4v2 (Revolution for DS Version 2) when it release a non-spring loaded version of the R4 card in late 2007. This was to get rid of spring mechanism failure which was quite common in the R4DS. Now only the non-spring version R4v2 is sold on the market.

2.2.2) R4v2 package

The R4v2 package comes with the R4v2 DS card itself, a blue protective case to protect the R4v2 DS card, a USB-micro SD adapter and a disc which contains the R4v2 firmware. R4v2 firmware can also be downloaded from the manufacturer site. All this are contained inside a blackish green paper packaging box. The R4v2 package does not include the micro SD which must be purchase separately.

2.2.3) Advantage of R4v2

The R4v2 still have the fastest loading performance of any DS card on the market even though it was one of the earliest DS card released. The R4v2 also have many other functions which was created by the R4v2 development team and are now a standard in other DS card. These functions includes the ability to play mp3 music, watch videos and read e-book on the Nintendo DS console. Currently the R4v2 is also the cheapest DS card on the market. It is also quite a stable card and has a very low failure rate (less than 1%). Other R4 brands have a failure rate of 4-10% and the really bad ones can reach 20%.

2.2.3) Drawback of the R4v2

The R4v2 can only take micro SD with 2GB memory size or below. Newer DS cards can now take micro SD with memory size upto 32GB. The R4v2 also have some game compatibility issues whereas some of the best newer DS cards have 100% game compatibility.

2.3) R4 SDHC

2.3.1) History of R4 SDHC

The R4 SDHC is one of 30+ R4 brands that come after the R4v2. Unliked most of the other 30+ brands which are unreliable, unstable and rubbished, the R4 SDHC has proven to be a very good DS card. Some of the development team members of the original R4v2 is now working for the R4 SDHC developmental team.

2.3.2) R4 SDHC package

Very similar to the R4v2. Comes with the R4 SDHC card itself, a blue protective case, a USB-micro SD adapter. Does not come with a disc containing the R4 SDHC firmware as the R4 SDHC manufacturer made it available to download online. Reason for this is because the firmware is constantly being updated and its easier to provide a download service. All this are contained inside a blackish green paper packaging box with the brand name R4 SDHC written on it. The R4 SDHC package does not include the micro SD which must be purchased separately.

2.3.3) Advantage of R4 SDHC

The advantage of R4 SDHC is that it is able to take micro SDHC with memory of upto 32GB, hence its name. It also have 100% game compatibility and has all the standard functions available in the R4v2 such as the ability to play mp3 music, watch videos and read e-book on the Nintendo DS console. The R4 SDHC is also a very stable card with low failure rate (less than 1%). A good jake of all trade DS card.

2.3.4) Drawbacks of R4 SDHC

R4 cheat database is limited compare to the cheat database of the best DS brands on the market. Does not have some of the functions of newer DS cards.

3) Solutions to common R4 Problems

3.1) Fising the R4 ‘Loading…’ Screen Problem

Probably the most common problem with the R4DS Card, regardless of whether you are using the R4v2 or R4 SDHC, is the “Loading…” error. The majority of people assume that this is because their adapter is broken, and immediately panic or send their card back. However, this is not normally the case if you’ve bought a genuine product. The most common problem is that you have the wrong software for your R4 adapter. Visit our Software Download page for help recognising what kind of card you have, and links to software downloads for the R4v2 and R4 SDHC.

3.1.1) Six Steps to Solve the “Loading” Problem

3.1.1.1) Make sure you have downloaded the right software. For help with this, please visit our Downloads page here.

3.1.1.2) Make sure the software is placed inside the root directory of your Micro-SD card – the ‘base’ or first directory of your Micro-SD card. What your Micro-SD card’s files should look like, can be seen below.

3.1.1.3) Give your Micro-SD card a quick clean (a good blow or two, as the card contacts can be sensitive to dirt).

3.1.1.4) For optimum performance, do not overload your Micro-SD card. The remainder of your Micro-SD card’s memory is needed to keep your card running in tip top shape. As a guide, we recommend filling your Micro-SD card to no more than 60% full. That means that for a 1GB card, we only recommend filling it up to 600MB full of applications and games. For a 2GB card, we recommend only filling it up to 1.2GB full,and so on.

3.1.1.5) Make sure the Micro-SD is card pushed down completely into the DS adapter (ensure good contact between Micro-SD card and R4 adapter). In a very small minority of cases, the Micro-SD has to be pulled up a bit if the ‘click’ between the Micro-SD and the R4 card causes them to misalign. This is more common with the R4 SDHC than with the R4, but is nonetheless a non-issue.

3.1.1.6) Reformat your Micro-SD to (FAT16/32) for optimal performance.

3.1.1.7) Use only the following sizes of Micro-SD/ SDHC: 1, 2, 4, 8, 16, 24 and 32GB. The R4 SDHC is untested for Micro-SD cards above 32GB and problems are reported for 6GB micro SD. For the R4v2, only use 2GB Micro-SD cards or below, as higher capacity Micro-SDHC cards do not work.

3.2) Fixing the ‘There is no DS Card Inserted’ Screen Problem

One of the more uncommon error message which appears on the normal DS load page. It usually have the message that goes:

“There is no DS card inserted” on the top line and “There is no game pak inserted” on the bottom line.

In this case, the “There is no game pak inserted” is a pretty standard message as it relates to the slot 2 of the DS which is empty – DS cards/adapters do not use that slot these days. However, the “There is no DS card inserted” message is worrying. There is many reasons for this message, which can range from dirt / dust on the micro-SD card, corrupt micro-SD data, a faulty R4v2 card / micro-SD connector, or the more serious and worrying misalignment of the DS slot 1 connectors.

The dirt/dust problem on the micro-SD card can be easily solved by giving the micro-SD a good blow or two. A corrupt micro-SD card’s data can be easily fixed by reformatting it to FAT16 or FAT32. A faulty R4v2 card and micro-SD should be exchanged with the retailer – only e-mail them after the first two options don’t appear to have worked, though, because about 99% of the time one of those will fix it. For more information, see NDS-Gear’s FAQ page which gives some details on how to fix similar problems.

Very rarely, a DS adapter can work on one DS but fail to work on another and the failed adapter will display this message. In this rare circumstance, a tiny imperfection in the DS and the DS card may sometimes be great enough that they just about misalign and are unable to communicate with each other. Basically, the metal contacts don’t touch each other well enough. This is incredibly rare but potentially worrying as it could signify a problem with the DS console – in which case a different card which has a slightly larger design (the EDGE DS in particular has a rather snug fit, and would be ideal for people with this problem) would be desirable. This only happens in less than 1% of cases, though, and it tends to be with old DS’s or well-used DS Lites.

However, if the DS fails with every DS card, then there is a definite problem with the SLOT 1 connector of the DS. If the DS is still under warranty, it should be exchange immediately for a new one. If your DS is out of warranty, it is also possible to realign the connector pins in the SLOT 1 of the DS yourself (WARNING: Doing this yourself will void the warranty). You would need to very carefully peer into the slot where cartridges normally go, and use some thin, fine tools to re-align any bent pins in the SLOT 1 connector.

3.3) Unable to load newer games of the R4v2

“‘The save data cannot be accessed. Please turn the power off and reinsert the DS card”

This is an error message on the R4 card which usually occurs when the R4 firmware is outdated. The most common cause for this message is when newer DS games which uses the ARM7 binary executable system file is loaded using out of date R4 firmware. This is a particularly acute problem for the R4v2 which no longer release updates for their firmware.

If you are running any other DS cards other than the R4v2, get (or wait) for the latest release firmware to come out and update the firmware of the DS card. This should hopefully fix the problem as the development team periodically include fixes for game compatibility issues.

If you are running an R4v2, you can get the unofficial R4v2 software like the Yasu software which fixes many but not all of the problems.

Another solution for this problem is to replaced the ARM7 executable file with an older version executable file that is recognised by the R4v2 firmware. To do this, you will need the problem game ROM, another ROM with the older executable files (Works on the DS) and the software to patch the executable files from the older ROM onto the newer not working one.

R4DS-Forums appears to have a workaround if you are experiencing problems. However, NDS-Gear cannot and will not offer support for any unofficial firmware / software used with your DS card.

GBATemp have also published a similar if not identical workaround. Please remember NDS-Gear cannot provide support for this.

Please remember – IF YOU LIKE IT, BUY IT – DS cards are meant as multimedia devices and to backup games that you legitimately own. Do not play games that you do not already legally own. Thanks for helping the gaming industry! 🙂

The Use of Ceramic Ferrules in Stud Welding

Published

on

By

Ceramic ferrules are vital in the drawn arc stud welding process, and this blog can help you to understand it.

Ferrules are protective rings used to protect the stud during welding, and in a variety of applications, from fiber optics to stud welding. As a result, the materials involved in the welding process are less likely to be contaminated.

Small rings derived from ceramic material are called ceramic ferrules (also known as ceramic arc shields), which allows an effective drawn arc stud welding process to work. Without these, the procedure will be ineffective, and the welds will be weak. So, understanding how drawn arc stud welding works is critical.

First, the drawn arc machine is calibrated for the appropriate stud diameter. The stud is then positioned on the plate and prepared to be welded. When the process starts, the stud is slightly lifted from the plate and a pilot-arc follows.

Subsequently, the main arc that melts the stud tip into molten metal develops a metal pool on the plate. Next, the machine return-springs the stud to the plate, fusing it with the molten metal to make the extremely strong weld.

Ferrules are needed to contain the molten metal pool, preventing it from spreading ouward and leaving insufficient metal to fuse the stud to the plate and resulting in a sloppy finish.

The ceramic primarily protects the stud from the air, preventing porosity and contaminants during the welding process, and reduces UV exposure in the surrounding area. They form a ring around the stud, containing the molten pool between it and the plate. By containing the molten metal, the weld is shaped to create a neat join that is invisible and smooth.

When finished, the ferrule must be removed. Because they are ceramic, an operator easily chips away the ferrules to expose the finished weld.

They are essential, but there are some stud welding processes where they are not used, like short cycle stud welding that uses inert shielding gas in place of ferrules. It keeps contaminants in the air from affecting the molten metal, changing its properties and potentially weakening the weld. Likewise for capacitor discharge stud welding, because the different process eliminates the risk of molten metal spreading beyond the stud.

The simplest way to get ceramic ferrules for your drawn arc process is to order your drawn arc studs from Shanghai Ceratek Advance Ceramic Technology Co., Limited. All our DA studs, regardless of diameter or material, come with ceramic ferrules, so no need to pay extra for them because they’re an important part of the process.

Apple Responds to the Market With New Products

Published

on

By

New products are on their way from Apple. The tech firm made it clear they have lots of items in their pipeline at their WWDC Conference this month.

First off is the company’s answer to Amazon’s Echo and Google’s Home called the HomePod. It is a seven inch device that will integrate Siri into an Echo/Home like case. You can use it to check the news, weather and control your smart home devices.

HomePod will offer an enhanced music experience. A feature called “Musicologist” will work with Apple music and stream the songs you request from Siri. The sound is designed to fill the room and take it to a level beyond what Amazon and Google are offering.

The device will be available in black or white. Price is around $349. The launch date is anticipated in December just in time for the holiday season.

Need a new desktop? Apple is updating its iMac with improved retina displays, a boost in graphics, Kaby Lake processors and a USB-C plug-in.

An iMac Pro is also on the way. This high-end machine has a 5K display with improved cooling capacity, and 8-core Xeon processor which is upgradeable up to 18-core. It also includes up to 4TB of SSD, up to 128GB of ECC memory, four Thunderbolt 3 ports, and built-in 10GB Ethernet.

Pricing is what you would expect from Apple. The new iMac starts at $1,099 for the 21.5-inch model, and $1,299 for the 4K model. MacBook Pro starts at $1,299, which includes the updated Kaby Lake processor. For those with deep pockets the iMac Pro with the Xeon processor starts at a whopping $4,999. Again a December shipping date in expected.

Speaking of “Pros” how about a new iPad Pro? The device will be available in three sizes including a brand new 10.5 inch model. Similar to the iPhone 7 it comes with a 12-megapixel camera and a 7MP selfie cam.

The iPad Pro supports USB 3.0 with 10 hours of battery life. A new feature called ProMotion reduces the Apple Pencil’s latency to 20 milliseconds. It adjusts the refresh rate based on what you are watching and can double it up to 120Hz. The 10.5 inch iPad Pro starts with a 64GB configuration. Pricing begins at $649. You can pick one up now.

Also of note is Apple’s new operating system, iOS11. It is in beta stage and has been released to developers. One area it will improve is multitasking on the iPad. Users will be able to pull up an app from the dock and drag it onto the screen in split-screen version. Like a MacBook you can use touch to hold and drag folders, files or photos. You can even drop them in a different app such as Mail or iMessage. The Apple Pencil will also enable handwritten text to be searchable from the Notes app.

The Apple Watch is also getting a “face lift”. New faces will display new bits of information such as Siri reminders. A Fitness Focus update provides NFC-enabled data sharing with gym equipment. Pair the two and you get the latest calorie burn and activity level.

Apple is letting developers know their tree is full of interesting new products and upgrades. It will be interesting to watch how the public responds in this latest round of Apple picking.
