  • This looks familiar…


  • I created a digital clock with these displays. I made a BackPack PCB that uses the TPIC6A595’s so you can daisy chain them. A link to a video demo is on my page here… http://damage-designs.com/blog/2011/5/28/arduino-based-large-digital-clock-with-7-segment-display.html

    The PCB files themselves are up on OSHPark…. http://oshpark.com/profiles/Damage


  • Would diffused leds work better? (eliminate the spot in the centers).

  • Is there a way to modify one or more of these (and bezels) to have a different number of columns besides multiples of 2/4? I need a 5x12 grid. I want to make a digital version of the boardgame Mastermind.

  • This is really interesting. I can’t wait to see your results. I hope you have a safe trip. I am really interested in the teardown, I might copy this project :), been wanting to do something with a geiger counter for a while. Did you use uranium samples in testing?.. http://unitednuclear.com/index.php?main_page=product_info&cPath=2_4&products_id=460

  • Regarding the big dome switches, Do you guys sell an LED retrofit for those of us who have the older red ones with the lamp? Or know where we can get one?

  • Does this stuff need to be stored refrigerated like the leaded stuff after opening?

  • The segments appear to be symmetrical. They also look like they could easily be desoldered but I have not tried myself. I think you could desolder each one individually, flip each 180 in place and resolder and probably convert it to common cathode that way.

  • I have a newbie general question regarding Hot Air Rework. I have recently bought this Hot Air Rework station to be able to bump ICs and remove them, etc. My question is how do semiconductors not burn out or fry under the heat? granted you are not applying heat directly to the chip, but I have always been told with conventional soldering not to keep the iron on a pin for any longer then you have to in order to protect the part. With applying ‘solder melting’ level of heat to all pins wouldn’t that be a problem? I ask this, but I also must admit that I have been doing some work with this unit and have not had any of these issues as of yet. I just am wondering how concerned I should be about this.

  • I can confirm these will work with the Hakko 907 iron. I rolled the dice and ordered one and it is the exact tip that I replaced.

No public wish lists :(
