About a month ago I managed to go ahead and buy my first quadcopter (split the cost with two of my colleagues :) ) and all the required equipment. I will do another post on that because it is really interesting! I played around with RC airplanes some 10 years ago. There are some things changed [...]]]> http://psychoul.com/electronics/how-to-make-your-own-usb-cable-for-hk-t6a-calibration/feed 5 http://psychoul.com/general/double-fine-adventure-almost-at-2000000 http://psychoul.com/general/double-fine-adventure-almost-at-2000000#comments Sat, 18 Feb 2012 18:16:04 +0000 psychoul http://psychoul.com/?p=335 div.img { height:auto; width: 33%; float: left; text-align: center; } div.img img { display: inline; margin: 2px; height:auto; width: auto; border: 1px solid #ffffff; } div.img a:hover img {border: 1px solid #0000ff;} div.desc { text-align: center; font-weight: normal; width: auto; margin: 2px; padding-bottom:1cm; } If you haven’t already heard, this game already collected $1.9+ as a kickstarter project. WOW!!! I am also backing the project and I really hope it turns out well. Those guys really deserve it. I have such great memories playing their games as a kid. Go Tim go!  ]]> http://psychoul.com/general/double-fine-adventure-almost-at-2000000/feed 0 http://psychoul.com/electronics/using-tmp100-temperature-sensor-with-your-pic-pr5 http://psychoul.com/electronics/using-tmp100-temperature-sensor-with-your-pic-pr5#comments Tue, 31 Jan 2012 15:27:06 +0000 psychoul http://psychoul.com/?p=312 div.img { height:auto; width: 33%; float: left; text-align: center; } div.img img { display: inline; margin: 2px; height:auto; width: auto; border: 1px solid #ffffff; } div.img a:hover img {border: 1px solid #0000ff;} div.desc { text-align: center; font-weight: normal; width: auto; margin: 2px; padding-bottom:1cm; } In this post I will describe how you can connect the TMP100 temperature sensor from TI to your PIC as well as receive temperature data. The sensor I am using is a generous sample from TI. Compared to the DS18S20 that I used before, this sensor is much faster, it takes 40ms to take a measurement with [...]]]> http://psychoul.com/electronics/using-tmp100-temperature-sensor-with-your-pic-pr5/feed 0 http://psychoul.com/electronics/1-wire-onewire-c18-library-2 http://psychoul.com/electronics/1-wire-onewire-c18-library-2#comments Thu, 17 Nov 2011 09:38:09 +0000 psychoul http://psychoul.com/?p=296 div.img { height:auto; width: 33%; float: left; text-align: center; } div.img img { display: inline; margin: 2px; height:auto; width: auto; border: 1px solid #ffffff; } div.img a:hover img {border: 1px solid #0000ff;} div.desc { text-align: center; font-weight: normal; width: auto; margin: 2px; padding-bottom:1cm; } So yesterday I wanted to get some temperature measurements from a DS18S20 thermometer to my PIC prototyping board. This thermometer uses the 1-Wire communication protocol so I searched around to find a 1-Wire library for the C18 compiler I am using. Maybe I am wrong but I couldn’t find any. So I created one, hence [...]]]> http://psychoul.com/electronics/1-wire-onewire-c18-library-2/feed 0 http://psychoul.com/cnc/path-optimize-for-pcb-gcode http://psychoul.com/cnc/path-optimize-for-pcb-gcode#comments Sat, 12 Nov 2011 23:06:15 +0000 psychoul http://psychoul.com/?p=282 div.img { height:auto; width: 33%; float: left; text-align: center; } div.img img { display: inline; margin: 2px; height:auto; width: auto; border: 1px solid #ffffff; } div.img a:hover img {border: 1px solid #0000ff;} div.desc { text-align: center; font-weight: normal; width: auto; margin: 2px; padding-bottom:1cm; } The last couple of days I used the CNC machine to create a PCB for a project I am working on. As the CNC was etching away the copper, I noticed that between paths (i.e. while the spindle was not cutting) there was a lot of unnecessary travel. This happened quite a few times during my 35 [...]]]> http://psychoul.com/cnc/path-optimize-for-pcb-gcode/feed 0 http://psychoul.com/cnc/how-to-flatten-the-cnc-table http://psychoul.com/cnc/how-to-flatten-the-cnc-table#comments Thu, 03 Nov 2011 21:16:46 +0000 psychoul http://psychoul.com/?p=274 div.img { height:auto; width: 33%; float: left; text-align: center; } div.img img { display: inline; margin: 2px; height:auto; width: auto; border: 1px solid #ffffff; } div.img a:hover img {border: 1px solid #0000ff;} div.desc { text-align: center; font-weight: normal; width: auto; margin: 2px; padding-bottom:1cm; } Hey guys, recently we got a medium-low end CNC machine in the lab I am working. We got it mainly for prototyping PCBs of our projects. I am still in the process of fine-tuning the machine. The learning curve was (is!) pretty steep and makes it even worst if you have little time to spend [...]]]> http://psychoul.com/cnc/how-to-flatten-the-cnc-table/feed 0 http://psychoul.com/electronics/serial-interface-between-pic-and-pc-pr4 http://psychoul.com/electronics/serial-interface-between-pic-and-pc-pr4#comments Tue, 04 Oct 2011 11:50:50 +0000 psychoul http://psychoul.com/?p=248 div.img { height:auto; width: 33%; float: left; text-align: center; } div.img img { display: inline; margin: 2px; height:auto; width: auto; border: 1px solid #ffffff; } div.img a:hover img {border: 1px solid #0000ff;} div.desc { text-align: center; font-weight: normal; width: auto; margin: 2px; padding-bottom:1cm; } This one is really useful. Most of the times you are developing a project, you will need some sort of monitoring or visual output to understand the status of your program. Sure some LEDs blinking are great but some times you need more. This is where the good old serial communication comes in.

This project is about interfacing and using a simple Graphic LCD. So to follow this project you need a PIC to have SPI hardware, in order to communicate with the device.

However, since then, I worked on tidying up this design into a more usable design (I wanted to play around with creating PCB actually ).

The result was successful! Personally this was a simple board carries a lot of “firsts” for me.
