cubeberg 540 Posted August 18, 2012 Share Posted August 18, 2012 Buy the IV-18 VFD Clock Kit at the 43oh Store. Here is my first booster pack. I created a prototype version using RobG's SMD ProtoPad. You can find the project thread here.Git Repository .Net app to set the time via serial - available on this post http://www.youtube.com/watch?v=m263zsmdeh0The idea is that this is usable as just a booster, but the buttons could be broken off and the whole project could be placed into a case (I'm working on a laser-cut design, but I'll probably wait until I get the boards first).All parts with the exception of the MC34063, Max6921 and Tube can be ordered @ TaydaElectronics - I was working to keep the cost very low.The tubes can be purchased in quantity for < $5 each on eBay. It might be worth organizing a group buy if there's enough interest.Any feature requests? I was thinking about adding a DS18B20 for temperature as well. Should I add the option to use the DIP MC34063 as well?Parts:MC34063AD (SOIC)Max6921AWI (SOIC)http://www.mouser.com/Search/ProductDetail.aspx?R=RLB0914-680KLvirtualkey65210000virtualkey652-RLB0914-680KL - 68uH inductor (1) - switched to Mouser parthttp://www.taydaelectronics.com/10uf-100v-105c-radial-electrolytic-capacitor-6x11mm.html - 10uF 100v Capacitor (x4)http://www.taydaelectronics.com/100uf-35v-105c-radial-electrolytic-capacitor-6x11mm.html - 100uF Capacitor (1)http://www.taydaelectronics.com/10-x-390pf-50v-ceramic-disc-capacitor-pkg-of-10.html - 390pF capacitor (1)http://www.taydaelectronics.com/1n5819-schottky-barrier-diode-1a-40v.html - 1N5819 Schottky (1)http://www.taydaelectronics.com/40-pin-2-54-mm-single-row-female-pin-header.html - 2x10 Female Header (1)http://www.taydaelectronics.com/10-x-resistor-180-ohm-1-4w-5-carbon-film-pkg-of-10.html - 180 ohm resistor (1)http://www.taydaelectronics.com/10-x-resistor-22k-ohm-1-4w-5-carbon-film-pkg-of-10.html - 22K resistor (1)http://www.taydaelectronics.com/10-x-resistor-1k-ohm-1-4w-5-carbon-film-pkg-of-10.html - 1K resistor (1)http://www.taydaelectronics.com/potentiometer-variable-resistors/trimmers/6mm-top-adjustment/10k-ohm-trimpot-variable-resistor-6mm.html - 10K Trimpot (2)http://www.taydaelectronics.com/10-x-resistor-22-ohm-1-4w-5-carbon-film-pkg-of-10.html - 22 ohm resistor (1)http://www.taydaelectronics.com/electromechanical/switches-key-pad/tact-switch/tact-switch-6x6mm-7-5mm-through-hole-spst-no.html - 6mm Tact Switch (3)http://www.taydaelectronics.com/connectors-sockets/pin-headers/2x40-pin-2-54-mm-right-angle-double-row-pin-header.html - 2x10 Right Angle male header (1)http://www.taydaelectronics.com/buzzers/piezo-electronic-tone-buzzer-alarm-3-28v-1.html - Piezo Buzzer (1 - Optional)http://www.taydaelectronics.com/10-x-resistor-16k-ohm-1-4w-5-carbon-film-pkg-of-10.html - 16k Resistor (1)http://www.taydaelectronics.com/t-transistors/2n-series/2n3904-npn-general-propose-transistor.html - 2n3904 or similar (1 - Optional)http://www.taydaelectronics.com/10-x-resistor-4-7k-4k7-ohm-1-4w-5-carbon-film-pkg-of-10.html - 4.7K resistor (1)http://www.taydaelectronics.com/ds18b20-1-wire-digital-temperature-sensor-ic-dallas.html - DS18B20 (1 - Optional)The required parts from Tayda come to about $1 (about $2 more for the piezo and temp sensor).

bluehash 1,581 Posted August 18, 2012 Share Posted August 18, 2012 Thanks! I'll start the GB for the displays. When you are ready to send the PCB to SEEED/iTead, I'll paypal you $10 for the first batch. Just let me know. I also suggest you link all the parts used, so its all in one place. Also.. I need a link to the displays. Quote Link to post Share on other sites
cubeberg 540 Posted August 18, 2012 Author Share Posted August 18, 2012 This is the guy I bought from - the tubes were the nice clear ones instead of the black background. Shipping for the first 5 is pretty steep, but only $3 more in shipping for additional groups. Quote Link to post Share on other sites
bluehash 1,581 Posted August 18, 2012 Share Posted August 18, 2012 Id suggest you get your BP made first.. I'll then start a GB for the displays. Sound good? Quote Link to post Share on other sites
cubeberg 540 Posted August 20, 2012 Author Share Posted August 20, 2012 All done! I printed out the board design and made sure the layout worked. I had to fix a couple of package issues with the resistors and inductor (the original ones I picked weren't big enough) and some items were too close together. I moved around a few things to allow them to route easier. I'm using auto-route pretty successfully thankfully. I added the DS18B20. Anything else I should add? A piezo buzzer? It'd have to be off-board (I don't think I can squeeze anything else in), but something like this might work. Quote Link to post Share on other sites
cubeberg 540 Posted August 20, 2012 Author Share Posted August 20, 2012 Oh - and I was also looking at this cable at Seeed for an easy solution for placing the display in a case. If anybody has any other suggestions for a 2x10 pin cable, let me know. I'll probably pick one up when I order the boards. Quote Link to post Share on other sites
bluehash 1,581 Posted August 20, 2012 Share Posted August 20, 2012 PM me your paypal. Once sponsored, you will have to put your eagle files and code here. Buzzer can be off board. Just provide pads for it. Quote Link to post Share on other sites

cubeberg 540 Posted August 20, 2012 Author Share Posted August 20, 2012 BH - thanks! SA - Sure - under the Max6921? Is there any way to do that with autoroute? Quote Link to post Share on other sites
cubeberg 540 Posted August 21, 2012 Author Share Posted August 21, 2012 Traces fixed, piezo added - boards sent in. I also added the code to the original post. I'll be adding in more features while I wait for the boards to come. Any idea how long these typically take to get to the US? Quote Link to post Share on other sites
bluehash 1,581 Posted August 21, 2012 Share Posted August 21, 2012 1 week to fab + 1 to 1.5 week ship cubeberg 1 Quote Link to post Share on other sites
cubeberg 540 Posted September 7, 2012 Author Share Posted September 7, 2012 Well apparently someone at USPS doesn't like me - PCB's have been sitting in NY for a week now. Hopefully they fare better than my eBay purchases from China, or I won't see them for another couple of weeks... However - I've made fantastic progress on the software. RTC is great and a Menu system is in place. The ability to set date/time is done and I'm working on the Alarm code and Buzzer feature. My attempts at getting the DS18B20 haven't gone too well right now, I'll be posting on oPossum's thread this weekend to see if I can figure it out. I'll probably add a menu option to use the internal sensor as well. I'm also considering adding the ability to read time from a GPS unit since I now have a GPS booster. I'll restart work on the case design once I get the PCB's and can do some better measurement. The local hackerspace is supposed to have their laser cutter up soon. bluehash 1 Quote Link to post Share on other sites
