These little devices had a 1. 5 inch 128x128 colour TFT as well as USB, batteries and 16 Mbytes of storage for around 140 pictures. Best of all they were very cheap, so I purchased a few to see if they could be re-purposed into something useful. Looking on ebay it seems these devices are common-place and it wouldn`t surprise me if most are internally identical

Here is the box for one of the frames I bought: Out of the three I bought two had LCDs marked FTM144D01N and the other had the marking LC12802. 2, however both models looked functionally identical. The issue I found was that there was no available information on the display via Google, the only reference I found was that the FTM144D01N was based on the ILI9163 LCD driver IC from ILITEK. Since I had more that one, I decided to leave one photo frame intact and remove the screen from the other. This would allow me to analyse the working frame whilst attempting to control the other on the breadboard. Use a pair of side cutters to remove the Li-Po battery. Make sure you insulate the positive wire once cut so you don`t short the battery. The battery is a 3. 7V Li-ion 120mAh cell which is very useful for other projects. Next place the circuit board in a vice and use the wick to remove the excess solder. Simply heat the soldering iron to about 340C and then place the braid over the connector (partly on the board and partly on the ribbon) then apply the flat soldering tip for a short time to remove the solder. Once that`s done you hold the LCD in one hand and run the soldering iron across the ribbon whilst gently twisting the LCD free from the circuit. The ribbon should come away easily. The first step to reverse engineering the LCD connections is to simply look at the connector itself. As can be seen in the following picture the...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
