A motorized coconut scrapper

My dad, brother and me made a motorized coconut scrapping machine. Thought of sharing with everyone on how we made it.

The total cost would come to around 5000 Rs. The price is inclusive of

  1. cost of making the stand, 
  2. shaping the metallic scraper part (lathe required), 
  3. 2 splendour motorbike ball bearings, 
  4. 2 pulleys, 
  5. 1 belt, 
  6. 1 shaft for attaching big pulley to ball bearings (lathe required)
  7. Motor 1400 rpm. This itself costs 4000 Rs.!!!!
  8. Screws for attaching the machine to table
  9. flat plastic container for preventing the scraped coconut from flying all over the place. :-)
  10. We also made the table, but designed a very ugly looking sturdy table. Pressed wood will not do.
The mechanics are very easy to understand and the stand is quite strong to take a good beating for several years. The pulley system is required to lower the speed of the motor without losing torque. The parts which require machining are the actual scrapper shown in Fig 9 and the drive shaft attachment between the ball bearings shown in Fig 6 and 7.

Basic Econometrics - Chapter 1 - Exercise 1

Exercise 1.1 Table 1.2 gives data on the Consumer Price Index (CPI) for seven industrialized countries with 1982-1984 = 100 as base of the index. a. From the given data, compute the inflation rate of each country. b. Plot the inflation rate for each country against time (i.e. use the horizantal axis for time and the vertical axis for the inflation rate) c. What broad conclusions can you draw abou the inflation experience in the seven countries? d. Which countries inflation seems to be most variable? Can you offer any explanation? ## Note here I have to skip several rows and add column names. Have a look at ## the raw data. Column names are c('Year', 'Canada', 'France', 'Germany', ## 'Italy','Japan', 'UK', 'US') cpi <- read.table("https://raw.githubusercontent.com/cablegui/Econometrics/master/OriginalData/Table%201.2.txt", skip = 6, col.names = c("Ye...

Step by step guide to installing and using miktex with RStudio (Windows)

Using miktex with Rstudio is very easy with the miktex portable app available from http://miktex.org/portable. Steps 1. Follow the instructions from http://miktex.org/portable to download and unzip the miktex portable application in a loccation of your choice. 2. In R write the following code in a script and save it. Note that the E:\\Software-Silo\\Miktex\\miktex\\bin location is the location where I unzipped the miktex portable application. # Install miktex y <- Sys.getenv("PATH") x <- paste0(y,";","E:\\Software-Silo\\Miktex\\miktex\\bin") Sys.setenv(PATH=x) 3. Run Miktex by double clicking the following application "miktex-portable.cmd" in the Miktex main directory. 4. Run step 2 in RStudio to install the path into R environment. 5. Open a new RNW in RStudio to test whether Miktex works . 6. Run Compile PDF in RStudio. It should be just at the top of the RNW file created in step 5. 7. You will now see a PDF file whic...

Installing and using ROracle in R

Hi, Hope this post keeps you in the best of health. I am an oracle user and wanted to know how to fetch database information in R. There is a package out there called ROracle but there are no binaries for it and it thus needs to be built and then installed. Here are the steps to install it on Windows 7 machines. 1. Download the package from http://cran.r-project.org/web/packages/ROracle/index.html. Since I wrote this post the latest that was available was  ROracle_1.1-12.tar.gz . 2. Place the package in the directory where R is installed. I placed mine in E:\R\R-3.0.2\bin folder. 3. Install RTools from http://cran.r-project.org/bin/windows/Rtools/. Since my R version is R-3.0.2 the toolkit I needed was RTools31.exe. 4. Install the Rtools software in the R home directory. I placed mine in E:\R\Rtools. Place all the extras in there too. For example I placed my 32 bit extras in E:\R\RExtras32 and the 64 bit in E:\R\RExtras64 folder. These extras are not necessary for ...
