    Thank you both for your suggestions, Suspend and wakeup worked perfectly. I spent four
    Days studying the various tutorials and could not find this solution. I should have posted first

    cubeberg got a reaction from JimInAshland in IV-18 VFD Tube   
    Ever since I saw them a couple of years back, I've always loved Nixie Tubes. For now, because of cost and lack of experience with High Voltage - I decided to build a project based on the much more affordable, and lower voltage IV-18 tube.
     
    Much of this project is based on Lady Ada's Ice Tube Clock with the exception of the boost circuit.
     
    I used a MC34063 for the 30-50V boost from 5v (see here for circuit and values to use). I used some cheap inductors from Tayda Electronics, so the cost was pretty low.
     
    The Max6921 is used for VFD control - same as the Ice Tube Clock, although I went with the SOIC version. Thanks a ton to RobG for the SMD ProtoPad which allowed me to create a simple BP which contains both the VFD boost and drive control.
     
    For now, the code only handles display of a buffer of characters and a font table. That table defaults to "43oh.com", but can be updated via serial connection. I'm planning on adding the ability to control the clock via a serial bluetooth connection - I used the BluePack.
     
    I'm planning on adding RTC functionality as well as alarms - those will come later. For now - here is my current code, as well as a few pictures.
     
    Enjoy!

    Hi there,
     
    We support the CC3200, Tiva C Connected Launchpad, and the CC3100 Boosterpack for the MSP430 and the Tiva C Launchpads. We don't officially support the MSP432 yet.

    Hi all, 
     
    Over at Temboo, we've just released a new feature called Streaming. It short, Streaming makes it simple to connect your MSP430 LaunchPad to cloud data storage and visualization services. You can learn all about it at the link below, and let me know if you have any questions!

    Probably - my understanding is that solar cells "build up" a voltage charge, sort of like static, when they don't have any load on them (photons keep smacking the silicon knocking off electrons but those electrons don't have anywhere to go), so the voltage seen at the ADC would be higher than usual... whereas having the battery in the circuit will put a constant load on the solar cell.

    Hi Everyone,
     
    Great forum here at 43oh. We're new here, but was reached out on Twitter to share our new project / product we're working on. We're an education robotics startup in Canada (Hamilton, Ontario). 
     
    The product we've created is called the Print-A-Bot and it's a collection of 3D printed robots using the Launchpad MSP430. Our first model is the Print-A-Bot ARM.
     
     
    You can check it out at www.roboteurs.com
     
    We designed it in a way that you can print it yourself, even with a low resolution printer.
     
    We haven't posted the design files yet, but will soon.
     
    Please let us know what you think!
     
    Thanks!
     
    Justin

    Due to this thread I went out and picked up a handful of these at the dollar store.  These came with a AAA ni-cad battery. @cubeberg  I took a look at the specs for the battery and it looks like they have a fully charged/no load terminal voltage of 1.25 to 1.35 volts so 2 cells should max out at about 2.7V assuming the solar cell isn't able to push them slightly higher.

    Reset and Test are needed for SBW programming (and at a minimum GND for obvious reasons).  I typically add a 4 pin header to my custom boards (VCC, GND, TEST, RST).

    So my issue right now - the max charge daily keeps going up!  Slowly - and it's decently below 3v at this point (2.52v today) - but it keeps going up daily (202, 208, 213, 215).  I may have to add some code in to turn on an LED until the value falls below a threshold.

    Interestingly enough - I checked my sensor yesterday - there was water in the zip-loc bag
     
    Thanks for all of the feedback on housing, etc. guys!  I'll keep it all in mind - I'm expecting at least 3 outdoor sensors (wind speed + direction, rain, light + temp + humidity) - so taking care of them will be important.  I did see some 3D-printed Stevenson screens mentioned in weather sensor projects for humidity/temp sensors that needed to be exposed, but not directly to elements.  That will likely be a necessary part of the project. 
     
    Luke - I'll email you  I'm using the core cpu temperature measurement from the msp430 + calibration - but it's horribly inaccurate (not surprising).  Better sensors would be great!
    I know TI has a new chip they were demoing for battery-less sensors - I might look into that as well.  Can't beat $4 though - or $2 if they're available at the $ store
     
    Once I've ordered more custom sensor boards (instead of an LP chucked into a tupperware container) - potting seems like a cheap solution.  
     
    Today is rainy and overcast - it'll be interesting to see how well the battery holds up.  Considering usage yesterday - I honestly expect it could last a couple of days without charging.

    I've got a bunch of sensors in my house uploading data to my phant repository - but I decided to start looking into placing sensors outside as well.  
    I purchased some $2 solar sensors from Target (Apparently they're frequently available from the dollar store as well - I'll check into that) in the hopes that I could use them to power an MSP430.  The ones I purchased only provide ~1.2v of power since they're single battery.  They're 200maH as well, but I think that will likely be plenty for my uses.  
     
    Since one wouldn't do it - I used two in series.  At full power - that should be around 2.4v - perfect for an MSP430.  I added a diode between the two just in case, and clipped the LED to avoid unneeded battery usage.  Hooking directly into the battery means that I get power all the time - great since I didn't just want power at night.  Plus - the power output for the LED is apparently pulsed - probably not good for the MSP430.  
     
    I've been watching the sensor values today - it dropped a bit overnight (very little to be honest - about 0.05v), but it's charging nicely right now.  I need to get a better container - but for now it's in a cheap tupperware container inside of a ziploc bag. Apparently the dollar store also sells locking containers with a gasket that would be perfect for this.  
     

     
    Here is my analog.io graph for battery level.  I'm not calculating the actual voltage - but it's out of 255 - 255 being a 3v reference voltage (technically vcc/2 compared to 1.5v reference).  So 198 is ~2.33v.  
     

     
    Next up - I've got some radioshack weather sensors (rain, wind speed & direction) that I'll be ripping the guts out of and replacing with MSP430 brains.  They'll get solar power as well.

    Seeed has some flash deals - including the Grove Boosterpack.  Works best with a 5529LP.  Won't work well with any LP with the low ADC limit (CC3200, MSP432 - corrected by @spirillis)

    The modules themselves are great - and there are other sensors that are 3v compliant - just don't have examples quite yet. The included brochure needs work (on its way), but the examples on Github are in much better shape now - https://github.com/Seeed-Studio/LaunchPad_kit
