Nokia teamed up with the Royal National Institute of Blind People (RNIB) to create a magnifier for its Lumia smartphones that could be a helpful tool for vision-impaired users. The Nokia Pocket Magnifier allows a user to turn a Lumia phone into a magnifying glass, pinching or sliding to zoom in and tapping to focus an image. Users can also freeze a viewfinder to improve viewing, save images, use a flashlight and add filters.
- I implemented the feature I wanted the most, that is the multimeter with simultaneous current and voltage measurements, with instant and average power consumption graphs to estimate battery life of my projects
- I spent WAY too much time creating tools to extract the original bitmaps and fonts from the original Nokia Firmware. My inner nerd is very satisfied, but this left me no time to add other interesting functions like the scope, the serial sniffer and the ESP8226 integration before the contest end
- The LiIon battery charger I ordered is stuck in a post office somewhere; once I get it, it's just a matter of connecting it to the header and I will be able to charge the Nokia battery from the Trinket's USB port
- There's a bit of noise in the input stage. That is due mostly to the long routing of the signals, as some components like the Trinket, the button pads and the backlight LEDs can't be moved around to optimize the board
This project gathered a good following, so I'm now wondering where I can bring it next. There are a few things to think about and some decisions to be made. The Teensy conversion should bring very interesting improvements, that could make the product worthwhile for a crowdfunding campaign, and/or make it an interestiong open source project. But this would mean leaving the Nokia part behind, as there are not many 3310 left, the display while good is still quite low res, and there may be copyright problems.
And by the way, I think that the Gabotronics Xminilab and Xprotolab are still the best choice for a device of that kind, even if they're missing the whole current and power measurements that first pushed me to this quest. -portable-oscilloscope.htm
I foresee two "extreme" paths, and a whole lot of other viable paths inbetween. The best thing would be a community effort to expand and improve the Xprotolab by porting it to the Teensys Freescale micro (or better) and designing a platform with improved input handling and features; then a plethora of devices could be made, as it happened with the Gongkai ecosystem. I would build a board for the Nokia 3310, someone could build a Fluke lookalike case, or even an oscilloscope in a watch. The easy path would involve just designing boards for the original Xprotolab micro and work with its limitations, maybe with a second micro to handle UI, battery charging etc., as it's already happening with some customer-made Xprotolab devices.
I think that the only innovation that my device brought to the table is the Nokia 3310 "integration", but in the end that's just a gimmick, a novelty. Bringing this project forward would require a great effort, and I don't know if it will be worth it. I've done 80% of the work, with 20% of the effort. Should I leave this here as a nice exercise in creativity and a fun holiday project, or should I try to bring it to the next level by working the other 80% to complete the remaining 20% of the project?
...and it works! Other than more memory and more power, the Teensy also has two PGAs on board and two separated 16bit A/Ds that should help to improve significantly the original design. Well, the hardest part of the project is already done, now on to the porting!!
Well, today I started testing the analog input circuitry. As you can see, I'm soldering wires directly from resistors to the connector. The casual observer may see this as being too lazy to route a proper connector on the PCB, but it's really a very sophisticated way to relieve stress on the connector! :P
Now I know where all the holes and pads are, and I can draw the outline of the PCB. After a lot of failed attempts and frustration with various open source softwares, I ended up using Adobe Illustrator to create an exportable vector image of the outline and holes to feed to my Roland SRM-20 mill. Here she is cutting the PCB to size:
it fit very well, despite the PCB being thicker than the original (1.4mm instead of 1mm).
Time to fire up Eagle! I created a library for the phone footprint with the various pads for the LCD, buzzer, battery connector and buzzer and started laying out the board. I wanted to design a board that I could etch at home, so I had to stick with two layers, but I soon discovered that I had to give up the numeric pad to route all traces. I was still able to keep the function buttons, so I guess that I'll live with that for now!
Etching the board was a nightmare by itself, as my printer couldn't print a design this big on wax paper without scratching a lot of the toner away; Press'n'peel is not very good either for big boards with very thin traces. After dozens of failed tests, I was able to transfer the toner well enough with the good old photographic paper technique, being extra careful with every step of the process, even going as far as measuring the temperature of the iron before heating the board.
TA-DAAAHHH!! Not perfect, but still very nice and usable. Since the board is sandwitched under the screen plastic frame, I couldn't have anything protruding from the PCB, so I had to transform the Trinket to be surface solderable:
In the non-inverting configuration, the opamp gain is set by the two resistors ratio, and since one of them is grounded, I can add a resistor in parallel by connecting it to the MCU I/O and grounding the pin or setting it as an input to activate or deactivate it.
I looked around the web but couldn't find anyone supporting/bashing my theory (if someone has links discussing this, please let me know), so I just tried it and it works! With the ATMEGA328P in the Trinket you must connect the resistors to analog pins, or else it will still load the amp too much when set as a digital input. Setting the pin to analog input will leave the resistor floating, and setting it as a low digital output will connect the resistor to ground. This setup is not perfect, especially at low voltages, and it seemed to further reduce the bandwidth at high gains, probably due to the input pin capacity.
I decided to take the lazy route when designing the input stage, so to get a wide input range while keeping a good resolution I opted for a Programmable Gain Amplifier. I decided to order the Texas Instruments PGA113 as it's cheap, has 2 switchable inputs, a reference pin and a nice range of switchable gains. It comes with a choice of 8 multipliers (1, 2, 5, 10, 20, 50, 100, 200) and while the bandwidth is quite low (230kHz at the highest gain setting), it's still good enough for the Trinket ADC.
Dividing the input by 1:100 I calculated an acceptable resolution, but to get better results I would really need a 16bit ADC and a lower gains.
The PGA113 comes in a VSSOP package so I just decided to build a simple breakout board with the basic passives required to make the device work. I also included two precision voltage reference sources, selectable with a jumper.
The board has only one single jumper wire, so it can be printed on a single layer of a dual-layer PCB, keeping the back as a ground plane.
Everything worked on the first try! The PGA113 is quite simple to work with, and the datasheet is clear and complete; it was just a simple matter of modifying the SPI/digitalPot example to send the right two bytes, and I had my PGA working!
