    rebeltaz got a reaction from tingo in just wanted to show off my latest clock :)   
    Ok... so compared to some of the projects I see on here, I feel like amateur hour at the Apollo, but.... Here goes:
     
    I love building clocks, but I have no use for time itself. So a long time ago, I thought of doing this project. It wasn't until I fell in love with the MSP430 that I dusted it off and got to it. I call this piece "Beyond Time & Space."  It is 12"x24" and every bit is custom built and hand painted.
     
    I would love to be able to post this to Etsy or something and sell a few, but with what I have in this, both in materials and time, I'd have to charge close to $600 for it and I doubt anyone would be willing to pay that
     
    I need to get better pictures of the actual finished product, but I enjoy it and I hope you guys do, too!

    rebeltaz got a reaction from cde in trouble with battery backup   
    I'm only running this at 1MHz. I thought that the battery would be low enough, too, but without the resistor, it's only like 0.05-0.1v below the supply voltage and I didn't think that that was low enough. I even tried adding a 470uf capacitor across the supply pins on the MSP (pins 1 and 20) as well as a 470uF capacitor across the reset pin and ground to help in case the transition wasn't quick enough. Still no good.

    rebeltaz got a reaction from Rickta59 in trouble with battery backup   
    Hi...
     
    I managed to get my latest clock running with a 7447 as per my previous post without a ULN2003, but now I have another question.
     
    I'd like for this clock to have a battery backup. I figured it'd be a simple task of adding a cr2032 along with a couple of steering diodes and a resistor to make sure that the battery voltage was a little lower than the supply voltage. That's not working, though.
     
    I am attaching a copy of the power supply circuit I am using. The 12v supply goes to the digit LEDs. The 5v supply goes to the SN7447. The only thing that the 3.3v supply goes to is the MSP430's VCC pin1 and the reset pin16 through a 47k resistor.
     
    With the 12vdc adapter plugged in, there is about 2.6-2.7vdc on the 3.3v line. With the adapter unplugged, there is about 2.0-2.1vdc on the 3.3v line from the cr2032 battery. My code is written so that the main loop continuously scans the display with the watchdog timer taking care of updating the time, which is stored in the variables hh, mm and ss.
     
    I would think that as soon as the mains supply is removed, the battery should power the processor and that the MSP should be able to continue updating the time, and scanning the display, even though the display will not light since the LED and 7447 power supplies are removed. That is not what is happening, though. I can set the time, unplug the adapter and as soon as I plug it back in the display is flashing 12:00 again just like it is being powered on for the first time.
     
    Any ideas as to why this is not working? I'm open to any suggestions/criticism/feedback. Thanks.

    rebeltaz got a reaction from Rickta59 in homemade trainer lab -and- MSP430 vs ATX question :)   
    Hi, guys... I just wanted to share with you a few pictures of a trainer lab that I built. I have several old Heathkit trainers (hence the color scheme of mine ) but I needed features they didn't offer, so...
     
    On a related note, the power supply I am using for this is a converted ATX power supply. The 3.3v line puts out about 3.4v. This should be OK for powering MSP ICs, correct? I was thinking of putting a rectifier in series to drop it down a bit just to be safe, but I wanted to get a second opinion.

    rebeltaz got a reaction from abecedarian in moral question -or- my new Nixie clock   
    Hi, guys... I am just curious - do y'all ever sell any of the designs you create? I ask because I have designed (and built of course) what I consider a very beautiful Nixie Clock based on the MSP430 and I was thinking about selling the plans for it. I have everything - schematics, code, Sketchup files, actual size templates, etc... This took a lot of time and, while I feel bad asking people for money, I do have a lot (of time) invested in this. I just wanted to get your opinion on this.
     
    Oh, and of course, I wanted to show you the clock :grin: I am going to add brass accents to the two front faux drawers to set those off a little bit, but... I'm happy with it!

    @@rockets4kids - I've never had any luck selling anything on Etsy. I had some cute little teddy bear earrings that were made out of capacitors and little men earrings made out of electronic components. Everyone that saw them always wanted me to make them a pair, so I thought why not try to sell them on Etsy. I tried to get $21 a pair (they took some time to make) and when that didn't happen, I tried to clearance them out at $12 a pair. Still not a single bite :-(

    @@cubeberg - I do have the PCB design for the Nixie tube board, sort of. I hand routed the traces by cutting away the unesssary copper with a Dremel to create a double sided board. For the main prcoessor board and the smaller breakout board, I hand wired them on perfboard. BTW - I took a look at your VFD clock. That is very nice. I like that tube your using!

    I bought those "international copy" books when i was in university, from McGraw Hill and Prentice Hall. Yes content wise they are identical (except one rare case on accounting the original provided some exercise that is not in intl copy). The only differences are the mark that reads something like "not for sale in ...", and never in hard cover. The paper may be thinner in intl version. We are thankful to the publishers for offering these less expensive books.

    I guess I am just old school. On the last project I built - a MSP-based nixie clock - I drew the board patterns out on a piece of paper by hand, transferred the patterns to the copper clad with a sharpie and cut the traces out with a dremel tool and a hobby knife. Sure.. it may take more time, but I have the satisfaction of knowing that I actually did it by hand.
     
    @@chibiace - I like the board. I made one of those myself,  just with a longer cable. I also connected another cable that terminates in a 20-pin socket that I can plug into a breadboard to take the place of jumper wires from the headers. I'll post a photo of it later.

    My girlfriend wanted a Betta fish for Valentine's Day. When we got it home, I realized that it was a Tropical fish needing warm water - a slight problem in the winter. Using a coffee pot and the MSP430, I hacked together a (I think) pretty cool fish tank that not only looks good, but keep the little guy at a happy 75-80 degrees. Rather than rewrite everything, I am just going to link to my web page - I hope that is ok?
