Wave Lamp – Weathers and Alerts

Friday, December 29th, 2017

Not much to say here – I created an instructable with all the details:

3D Printed this wave lamp, controlling it with an ESP8266. It gets the weather from openweathermaps and changes colour based on the forecast for London. 

Large 3D Printer

Saturday, November 25th, 2017

I was reminded by a few colleagues that I have not updated this blog in years now. I guess, I’ve just been too busy playing to blog.

When I had moved to the US (2014), I had backed a kickstarter project called Cobblebot. I’m not even going to link to it here as it was a really bad experience, however it did get me started with 3D printing. With the help of fellow backers on Google+, I was able to build a decent printer that provided me lots of fun. I had never built it for anything serious and most of the things I ended up printing were downloads from thingiverse. But, it was fun nevertheless:

In it’s final version it was able to print a size of 14″x14″x14″; though I never printed anything that large. I built and re-built it multiple times with new upgrades all the time; mainly using ideas from the Google+ community

The first print was a hollow cube:

But went on to print lots of great prints once I had the settings and upgrades done. Some examples include:

One of the best upgrade I did was change the controller from RAMPS that came with the kit to a Cohesion3D ReMIX. It’s 32-bit, runs Smoothieware and makes the motions so smooth and results so amazing, I simply don’t know why everyone still uses the RAMPS controllers. I also wrote a blog post for 3DPrinterChat that describes how you can use the Smoothie compatible boards to easily replace your RAMPS controller.

Finally, the printer looked like this, before I disassembled it while moving from the US to UK:

Now, in  London, I’ve started to rebuild it and decided to supersize it:

Don’t ask why I did it; even I don’t know 🙂

Lessons while travelling in South India

Friday, October 18th, 2013

Some lessons from my recent trip to Kodai Kanal:

  1. Do not underestimate Bangalore traffic
  2. RB1 is not a separate coach number – it means B1 with RAC seat – nearly missed my train because I couldn’t find the coach.
  3. Railway station with the same name as the city you wish to reach may not be in the city – Kodai Kanal Road station is almost 80 km from the city
  4. Do not trust google maps – shows Elephant Valley Resort right next to the Kodai Lake – its around 20 km from there.
  5. Do not book a non-AC bus – just because you do not think you’ll need AC – the bus was uncomfortable as hell.

 

 

Replaced my macbook keyboard

Saturday, July 20th, 2013

A couple of months back, I had “cleaned” my macbook with Colin and ended up destroying my keyboard 🙁

Also, my extended warranty had expired just a few days back; so when I went to the Apple support centre – they gave me an estimate of ~15,000 INR. Considering that the macbook is >3 years old, and that I have 2 other laptops at home, the cost was not justified.

I searched the net for options and finally came up with the following:

Keyboard from: http://www.aliexpress.com/item/New-US-Keyboard-For-apple-MacBook-Unibody-A1342-MC516LL-A-MC207-2010-Free-Shipping/617432777.html

Tools from: http://www.aliexpress.com/item/Free-Shipping-15pc-Screwdriver-Torx-T5-T6-T8-T10-T15-Bit-PH-Tool-Set/738450527.html

And Instructions from:

http://www.ifixit.com/Guide/MacBook+Unibody+Model+A1342+Upper+Case+Replacement/2185/1

As these instructions are for replacement of the entire upper case – there were a few more steps and brute force required to pull out the old keyboard and replace the new one – in the process – I broke a few plastic parts – but the new one works like a charm 😀
