cubeberg 540 Posted April 10, 2013 Yep! I do web app development for the USAF (civil-service). At least for now... Just got notice that I'm probably getting cut due to the budget shenanigans. Ironic that I wanted a civil-service job because I thought it would be so stable. :-( Sent from my Galaxy Note 2 using Tapatalk 2 Sorry to hear that GD - I hope things turn out well. Thankfully - .Net is still in serious demand. Hopefully it won't be too difficult to find something else if it comes to that. Quote Share this post Link to post Share on other sites

GastonP 17 Posted September 30, 2013 Guys, just found a little typo in the library: http://doc.43oh.com/BoosterPack:IV-18_VFD_Clock Where it says: Your Launchpad should have shipped with a 13.768kHz crystal. Should say: Your Launchpad should have shipped with a 32.768kHz crystal. Nothing to be very fussy about, but it could mess up someone's ideas 1 bluehash reacted to this Quote Share this post Link to post Share on other sites
cubeberg 540 Posted September 30, 2013 Thanks for catching that - I'll get that fixed! Quote Share this post Link to post Share on other sites
cubeberg 540 Posted October 11, 2013 Quick teaser pics That's not the IV-18 - it's the (much) smaller IV-21. Still working out voltages though. This one runs on 9-12v, but should work with the same main board, just different component values for the boost circuit. 1 GeekDoc reacted to this Quote Share this post Link to post Share on other sites

will 17 Posted November 1, 2013 (edited) I need some help....I can't get the number right,and also when i plug in to my computer , it shows that "can't recognize usb device" Edited December 20, 2013 by bluehash [ADMIN] Please upload your files to 43oh, next time Quote Share this post Link to post Share on other sites
GastonP 17 Posted November 1, 2013 Sorry to ask but... are those copper wires enameled? They look like bare copper and shorted... Which fits well with what can be seen in the display. What's their function? Gaston Quote Share this post Link to post Share on other sites
will 17 Posted November 1, 2013 Well.... The copper wire is to connect the IC ( I broke the PCB when replace the MAX6921),and I check the wire not shorted Also the situation is the same before replacement Thanks for reply Quote Share this post Link to post Share on other sites
cubeberg 540 Posted November 3, 2013 Hm - what do you mean that you can't get the number right? It could possibly be your tube - I've had certain digits not work. It could also be that you don't have a good connection between the tube and board. The "Can't recognize USB Device" error concerns me - did it happen the first time you plugged it in? I'm assuming not since it looks like you're running code on the msp430. It's a possibility you've damaged the Launchpad somehow - fried the TIUSB device or something.

will 17 Posted November 3, 2013 the display is as the picture shows that didn't display the number right, and I'v check the connection between the tube and IC I think the msp430 isn't damage because I still can upload the code oh I notice another thing , when I unplug the USB ,every digit will shine.... I'm not sure if the tube were damage or the power But anyway ....I still need a new board beacuse I broke part of it Quote Share this post Link to post Share on other sites
cubeberg 540 Posted November 3, 2013 Ok - I think I figured it out. You soldered the headers into the tube board incorrectly - it should have been soldered into the other side. There is a small bit of text on the board that says something like "headers go in here". You can see the correct direction here: http://doc.43oh.com/images/4/4c/IV-18_vfd_boosterpack_msp430_launchpad.jpghttp://doc.43oh.com/images/4/4c/IV-18_vfd_boosterpack_msp430_launchpad.jpg Since it's backwards - I'm honestly surprised you haven't fried your tube. Are you seeing anything red inside the tube? You're probably driving the filament at 50v when it should be something like 2.3v. Until you get that fixed - do not plug in your tube board! If you're able to program the chip - that's good. Maybe it's the UART that's not being recognized? I'd check device manager to see if you've got a device without drivers when you plug in the LP.

will 17 Posted November 3, 2013 Maybe the power source (PC) was overload so windows can't recognize I did seen the red line when using iPad's charger........ Great thanks :grin: ,now I need a new board plus a tube and figure how to fix this one Quote Share this post Link to post Share on other sites
cubeberg 540 Posted November 12, 2013 Here's a quick pic of the IV-21 tube. I need to do some more tests on the stability of the boost circuit. It took a few component changes (still need to identify an inductor from DigiKey - using a cheap one right now) and a new adapter board, but it's working on the same main board as the IV-18 VFD. I ordered some other VFD tubes - hoping to come up with some other clock variations FYI - don't forget to check out @@Mybuster's VFD clock as well! - http://forum.43oh.com/topic/4572-vfd-tube-clock-with-msp430/ 2 GeekDoc and bluehash reacted to this Quote Share this post Link to post Share on other sites
