Beginning of 3D printing.

3D printing is the new trend and have been around for more than a couple of years. So after considering the cost involved and a lot of research, I concluded that it would be fun to learn something new.

Purchase
Finally that I have decided to get into it, I started researching on the options available based on ease of customization and cost. Being an electronics hobbyist, whats better than being able to tinker around with the circuits and be able to modify as per my requirements. Also being on a very constrained budget, instead of getting a ready to print printer I opted for a DIY kit.

I went through a lot of reviews, feedback and assembly videos for different printers like Anet A8, Anet A6, CR-10, Tevo Tarantula, Tornado, Black Widow. In India the price of a 3D printer kit begins from 20K INR. And finding a reliable seller was a pain. Some who are reliable were selling of a very high cost. So I directed my self towards Chinese manufacturers.


The Hunt for a printer
I browsed through a lot of products on Aliexpress.


Given the price and popularity I settled for Tevo Tarantula. Placed order during a sale and ended up paying $200 (13K INR)  and free shipping.

Tevo took 10 days to ship the product. Today as I write the product has been shipped using DHL. Might take another 10 days before it shows up. Now will have to wait and see what custom duty is charged.

more updates once I receive the printer.

Reasons not to buy from Paytm

Dear Readers,

This post is specifically meant for Indian Consumers who shop Online. I am sharing a recent incident and my takeaway from the incident. I shop online on various sites, but am afraid to try any new website. Some of the sites on trusted list are Amazon.in, Flipkart.com, ebay.in, Myntra.com(which is now app only). When It comes to snapdeal I am a bit nervous.

I used Paytm to recharge and pay bills. Never had a problem with recharge. But paying electricity bill did not go through. One fine day I thought why not try their market to place to buy something. The discounts did catch my attention and they were very lucrative.  So finally I placed an order and ended up in a mess. My reasons not buy are:

 https://paytm.com/

No Paytm Customer Service over telephone. Only Email, Twitter, Facebook.

 This a huge problem. Paytm does not respond to emails. You tweet and they realize they have to respond. Most of the time it takes 24Hrs or more for a response.

Customer Service Executives are just insane

 The executives here do not read emails and respond. Maybe they don't understand English.  They ask you for product pictures in case you receive damaged or incorrect product. Once you send it to them they reply asking the same question over again.

Turn Around Time is way too high

Now unless you have all the time in the world and ready to let go off your money, this is not the place to buy. Let me share my incident.

Day1: Ordered a product (shipping/delivery: 4-6days.) Was happy that will get a cash back of Rs.300 on a purchase of Rs.900
Day2: Seller has not yet shipped the item.
Day3: Sellers ships the item.
Day4: Item arrives at my doorstep(wow that was quick)
I open the parcel in front of the delivery guy, just to ensure the product is in there. Here comes the surprise... its not what I ordered. I ask the delivery guy to take the parcel back. He denies and says...Sir agar aapko return karna hai to request dal do koi aur aakar el jayega(Translation: Sir, in case you want to return the product raise a request and somebody else will collect it.)
Now I was mad and furious. I emailed Paytm care... on their website they quote a turn around time of 4Hrs. but no response. I tweet and wait... no response.

Day5: I tweet and got a reply stating we have replied on your email. I check my email and they ask for a proof. They want me to send the images of the invoice, the picture of actual product and reason how is it different. No issues. I click some pictures and emailed.

Day6: No response. I tweet and another email drops in. Again they want me to send the proof. I suggest that I have already sent. Assuming some idiot might have deleted it, I send pictures again.

Day7: No response. I post on their Facebook account. Now they want me to fill another form on their FB page. So I tweet, same email and again asking for proof. (Now its driving me nuts), later got an email that a return request has been place. Product would be picked up in next 5-7days. Wonderful, now I have to wait for another 5 days. The experience does not end here..I am still awaiting for the product to be picked. Will update once somebody picks up the product.

Thanks for reading, please share you views and share this post as much as possible to help others from such agony.

Assign Quick Clip(Notebook) Key to use as Camera for LG Optimus Vu P895

Hi,

After searching a lot and going through several post found a way to Root my LG Optimus Vu P895.
If you would like to Root, you can follow the post on XDA-Developer here. The motochopper worked with my P895.

Now coming to the key assignment on your phone follow the below mentioned steps. [Root Required]
(P.S. Please perform the steps below at your own risk. I'll not be responsible for any damage caused.)

  • Install a file manager which allows you to access the root file. I used SManager.
  • Open SManager and browse to the following path "/system/usr/keylayout"
  • You would find the file named "osp-input.kl" (Please create a backup copy of the file before editing the original)
  • Open this file in Text Editor with -rw- (read/write) permission.
  • Locate line "key 212 Quickclip" and change it to "key 212 CAMERA"
  • Save the file and write the changes to system.
  • Reboot your phone and it should work now.

If the file is not available , it might be due to different regions. Let me know your progress, in case you have any problems or have difficulty following the post, let me know and will try to help.

One of the reader of my blog asked me question which made me think. The questions was How to enable Virtual CD-ROM in Data Card?

Virtual CD-ROM in Computer

After some research I came up with an answer. So thought posting it so that everybody can benefit out of it.
Let me guide you step by step on How to enable Virtual CD-ROM on data card.

  1. We will need a software called MDMA which is free to download and can be downloaded from here: http://www.nerve.org.za/mdma/
  2. After downloading extract the file MDMA.exe to D: drive.
  3. Once you have installed the Drivers for your data card, open command prompt.
  4. On command prompt type "D:\mdma.exe u2diag:1" without quotes and hit enter.
  5. MDMA application should come up. The Data card will be ejected and replugged. The drivers will be reinstalled and now you should have your Virtual CD-ROM. 
  6. You can also disable it using the command "D:\mdma.exe u2diag:0"

There are a lot more commands that can be used, and can be seen using command "D:\mdma.exe /?"

I hope this helps. If you like this post, then please show your support by clicking on the "Like" button. This will encourage me to write more.

The journey of Asus RT-N13U router...continues

Continuing from my last post The journey of Asus RT-N13U router [User review] 

dd-wrt on Asus RT-N13U B1


After regular follow up with the Asus Customer Care, I finally got my Router replaced after 10 days. With a fear in my mind that I don't want to lose my router again, I began using it with the stock firmware and Asus Utility. The internet had no problem at all, but the Download Manager is Crap. I tried hard to make the most of Download Manager but I frequently kept loosing the downloads that had been partially completed. One fine day, I could not resist my self with trying the dd-wrt firmware.

So I went through a couple of tutorials, reviews to find the most stable firmware and some experience from past. I flashed my router again. And guess what this time I succeed. I have my Router running on dd-wrt, Also have Web Server, FTP server, Samba, and Transmission installed on a 2 GB pen drive. I have the Transmission client on my Android, thus I am not depended on my computer to start a torrent download.

So far so good....the router is truly amazing.
