Cellular IoT : SIM800L / ATMega1284 Solinius Sparrow

Hi, Read a few posts here about using the SIM800L module with a raspberry pi and having seen this project, mentioning it here, hoping it may be of interest to others : Solinius Sparrow: Cellular IoT with Global Connectivity https://ksr-ugc.imgix.net/assets/021/151/577/97deb718526b45899ade3910781e81a...

Re: Power supply specs

Basically, Yes and No, If you were to plug in 4 USB peripherals each requiring 500mA, then you'd need a better power supply, it really depends on what you're going to connect to the RPi in terms of peripherals and how hard making the processor work. Sure, you could run it off a 1A, 1.5A or 2A PSU, j...

Re: need help understanding

Download the first issue of the Magpi magazine and take it from there.

Re: Need a power supply recommendation

With regards to the current required : If you run them all (I.e. Red, green and blue together to produce white) at full brightness then it's 20 mA per LED so yes a MAXIMUM 7.2A current draw but if you're buying addressable led strips then you're probably paying the premium because you want not just ...

Re: SD card emulator

Hello, i am searching for a solution to grab the files that are written to a SD-card from a camera. Up to now i only found solutions to interface to an SD-card and not to emulate an SD-card! I could find an document that someone did this job with an microcontroller http://www.thinkmind.org/download...

Re: max voltage to power the pi2?

What's the highest voltage I can put on the GPIOs to power a RPi 2? I have a UBEC delivering 5.46V (specs say it should deliver 5Vm see here: http://www.hobbyking.com/hobbyking/store/__18789__5V_5A_UBEC_2_5S_Lipoly_7_2_21v_.html ) and would like to use it to power the Pi from a 7.4V LiPo, but I don...

Re: Needing a few things made will pay.

Hi, You said "I am wanting to put the computer and a screen in a central spot.." , what do you need the computer for ? You could manage it all with a microcontroller ? If you want to display the weight on a small screen, do you have something in mind for the screen ? If not, what about just an LCD d...
