Populate the board. You will need some good experience with 0805 SMD soldering, and some tools like soldering iron and hot air rework station. Start with the bottom side, with the microcontroller, the other ICs and finally the small passive components....
Start with the fun bit! Here's a short Organiser II buying guide I produced myself - consult the websites for more detailed/informed insights... There are four models of Organiser II - all should work with this project. I own two Organisers - a 1988-89...
In the arduino code set your WiFi credentials char wifissid[] = "ENTER YOUR WiFi SSID HERE"; char wifipass[] = "ENTER YOUR WiFi PASSWORD HERE"; Normally, the signal strength is displayed in dBm. But for a non techie person, the signal strength in terms...
MSP430G2231 Code:For a starting point I used this excellent project from Stefan Wendler. MSP430G2231 Software UART. The code below replaces main.c from his “timer-a-uart” branch.#include #include #include "uart.h" #define BUTTON BIT3 //...
Yate(Yet Another Telephony Engine):Answering Google Voice calls that are forwarded to Google chat is tricky if you don't want to use the Gmail chat application. I found the most functional results were achieved by using Yate, to create an SIP server...
Linphonec and Linphonecsh:This is the softphone I used to interact with the python program. It is a little particular to get working so here are some directions. First run linphonec once to create a .linphonerc configuration file in your home folder....
Now is a good time to cut your EL panel down to size. Lay the LCD on top of it and trace around it with a marker. I chose to have the leads going out the right side (facing the front of the screen). You can cut the EL panel with scissors. You might want...
Now we need to get the metal plate off of the screen. This is the most dangerous part of the project. Get some rubbing acohol and pour it into the holes in the back of the plate. This will help dissolve the adhesive holding it to the screen. I let the...
Now is a good time to test your LCD and make sure it still works. Load the batteries back into the back half of the case. Press the motherboard against the back half of the case so the battery connectors make contact. Use a screwdriver or some other...
Assemble your LCD sandwich with the EL panel on the back, then the polarizer, then the glass. You can use some scotch tape around the edge to hold everything in place. I used some putty to stick the whole thing to the PCB, but you could also use some...
Find a good place to mount the push button that will control the backlight. I chose to put mine on the left side of the calculator, as you can see in the pictures. This was a very tight fit though. Some other suggestions would be on the top or under...
Now its time to take apart the inverter. Clip off the spring and solder some wires onto the battery contacts. The inverter will be powered by two of the calculator's AAs.The inverter has two buttons, but they both do the same thing. Desolder the button...
I added some drywall mesh tape just where the magnets were just in case they might cause drywall cracking if the force was strong enough. Then start to spread drywall compound (mud) evenly over the surface pushing it into the cracks.
Now to add some thin metal strips to the back of the HP Touchpad. I just used some black painted metal plates I had and some 3M Double sided tape. Bend the metal to follow the curve of the Touchpad's back.
