I have been pondering this question for a couple days after watching some of the new defcon conference videos.

let's say(for a hypothetical situation) you create a product using the espruino technology and your product gets released into the general population. Someone purchases your product for penetration purposes. And starts picking away at the circuitry. Will it be possible to do some sort of memory dump and get the firmware and your Javascript source code off the microprocessor?

I stumbled across this company that does this: http://www.break-ic.com

However, from a hobby prospective, which, in my opinion, was the reason for the Espruino's birth, I don't really see a concern for 'security measures'.

Ya, I thought as much. Espruino is awesome where it's at with performance. Allowing me to place them all over my house once I receive the picos :-)

I'm working on a project that uses a G400-S(GHI Electronics) that uses the arm processor that I mentioned earlier. I can program in C# when using their products. C# and Javascript are my two favorite languages.

Anyways, I thought hrmmm using arm 9 would be awesome with espruino on it :)

Out of curiousity, are there plans for a more powerful Espruino? An Espruino with massive amounts of ram that will allow memory hungry js scripts to run with out getting the out of memory error? And has a faster processor?

For an example, 400 MHz 32-bit ARM 9?

Thank you for summing this subject up in layman's terms :-)

I have a question which may have already been answered, but this thread is already long and way over my head.

Could these chips be used instead of the microcontrollers internal memory to execute memory intensive code, to hopefully fix the out of memory issue while running a memory intensive script?

This will come in handy :) thanks!

Great! Thanks.

@Gordon
Will you be releasing the finalized eagle cad foot print files for the pico before the Pico is shipped?

I need to get a PCB designed and was hoping to get one designed and receive my PCB right about the same time I receive my kickstarter pledge reward.

That's interesting. I will have to look into NaCI security.

@Gordon hi, in regards to using the Lora RF Module from that ebay link you posted which looks like it's from/based on HopeRF.... I read at https://openrf.codeplex.com that they aren't reliable. I'm not sure how much truth is in that statement about HopeRF? Are you creating an area specifically for the HopeRF LoRa module in that ebay listing or LoRa modules using the same dimensions?

Hi @Gordon, how is everything going with the design and manufacturing of the pico?

@Manxome,
I tested both yours and tage code. Using tage code I seem to receive more of a steady temp reading with very few temperature jumps. With your example I seem to receive a lot of temp fluctuations. For example, 73.0, 73.2, 73.3, 73.4, 73.5 and 73.7. I am taking 300 readings with both yours and tage code.

@DrAzzy Thanks for the explaination :)

Hi, Im curious as to how the firmware code handles the i2c bus. Please bear with me, I dont know enough of the terminology. How does the i2c bus 'know' how to split the incoming data into an object, later allowing the user to manipulate the data easily?

@DrAzzy In post #4 you wrote this link: cooking-hacks.com/documentati­on/tutorials/extreme-range-lora-sx1272-m­odule-shield-arduino-raspberry-pi-intel-­galileo

I scrolled through the page where it lists links under Kits and started clicking through the links to browse the different LoRa products they designed/carried and noticed the prices. Also: http://www.cooking-hacks.com/shop/arduino/designed-by-ch/extreme-range-lora-sx1272-module-shield-arduino-raspberry-pi-intel-galileo

Sorry for the confusion.

@Gordon At the time I wrote the post I forgot about the USB connectivity :-/ I didn't think it would be popular, but I wanted to mention the idea anyways.

Intel Edison adapter board with logic level converter for serial communication back and forth from espruino to the edison. :-)

For example: https://www.sparkfun.com/products/13036 (that uses Arduino)

@DrAzzy I checked out the link that you posted and wow those modules seem expensive especially €140.00(174.16 USD) for the Waspmote Gateway kit. I am assuming the range justifies the price?

@Gordon I see, well, hopefully adding castellations won't cost too much. If they do, then I will hack away at the board while keeping my fingers crossed :-)

@Gordon that was exactly what I thought! I didn't know what the terminology was called. Having both pins and castellations seems like a really good idea; however, I don't have experience with that design. Soldering the constellation design doesn't seem to difficult though, but I wouldn't feel comfortable hacking away at the PCBs to create an espruino with constellations.

I also thought about leaving the USB design for the board allowing me to solder the board down on the main board while leaving the USB side sticking off the side of the main board. Then use an USB cable specifically designed for an enclosure, where both sides of the cable are female, one side of the cable hooks onto the Espruino USB while the other female side of the USB cable attaches to inside of the encloser. I know that type of cable exists, I just forgot what the cable is called.

@thomc No, unfortunately I didn't get AES to work. I have been researching alternative methods for encryption such as communicating over serial to the Intel Edison and have the Edison handle encrypt/decryption.

I honestly would rather only use the Espruino. As far as porting a library over to javascript is well over my know how. I have stumbled across:http://forum.arduino.cc/index.php?topic=88890.0 maybe that can help you out. Please let me know if you port that over. Supporting all encryption will probably require a lot of ram so maybe just AES 128 will work?

I can definitely use the xPico as is for prototyping. I love the idea of the USB design.

I was thinking in more of the lines of esthetics for the 'final version' of my project.

I've always wanted a reflow oven kit, but I have no idea where to start for an inexpensive hobby reflow oven.

Is there plan to create another espruino Pico board offering all SMD and without the USB?
My thinking is to create a separate board to solder the xPico board down to.
The separate board will also have a USB port, power jack and other pinouts. The pinouts will be used for connecting a display and etc. The purpose of this idea is to create a more commercial/permanent/stationary project that will be mounted inside of a project box that also has a display.
This idea probably isn't popular enough to sell, but what about a section on GIT hub that lists espruino board variations?

@Manxome I will surely try that. I'll post back asap with the results.

If data is 1234 and there is no decimal point in the value, the display will only show 1234. I still have to add checks for how many digits and if the display comma needs to be enabled or not. For example, 25.2'C. I have an idea:
code:

if (char == "'") { 
I2C1.writeTo (a,0b00001000);  //turn on comma}
