Lord anubis 1 Posted May 12, 2014 Share Posted May 12, 2014 Thanks, and pitty. Are the known bugs all noted in this topic, or did you found newer ones? If so, any change that the design will be updated? Quote Link to post Share on other sites
greeeg 460 Posted May 15, 2014 Author Share Posted May 15, 2014 Thanks, and pitty. Are the known bugs all noted in this topic, or did you found newer ones? If so, any change that the design will be updated? They are mentioned in this thread, back a few pages. I am working on a new version. It will fix the (superficial) errors on the last revision. This will also add a more powerful MSP430. Also there might be a version in the 430 store in the near future. Stay tuned. GeekDoc 1 Quote Link to post Share on other sites
greeeg 460 Posted June 2, 2014 Author Share Posted June 2, 2014 Okay guys, sorry it took a bit longer than anticipated to roll this one out. This is the new version 3 of the ledRing boards. This is the controller, powered by msp430g2955. Stuck with the value line series, because it has very easy capacitive button features. I packaged these more professionally than the last. included in the zips: PCB (Altium format, gerber format, 3d step format) Schematic (Altium format, PDF) BOM (.xls and .pdf) [controller board only, slave boards are just 24x WS2812b + 0603 100nF decoupling caps] Downloads: Slave board: LedRing_03.zip Controller board: LedRingController_03.zip Major changes from last revision, GND pour is on bottom layer (non-LED side) VCC pour on front (LED side) Added more vias to capacitive slider elements (increase sensitivity) Corrected errata found in previous revision Increased the radius of the inner corner (more tolerant to manufacturing errors) Changed programming connector to tag-connect footprint Changed from G2553 to G2955 (8x more RAM, 3x more FLASH) Changed to proper level shiftier IC, from discrete FETs added footprints for IR reciever (BETA) added footprints for miniature buzzer (BETA) I've never used IR before, but I think it would be a good addition. Hope you guys enjoy. bluehash and dpharris 2 Quote Link to post Share on other sites

Lord anubis 1 Posted June 10, 2014 Share Posted June 10, 2014 Ouch, yes I see your in terrible need. You need some advise: please send only one posting and edit your posting to add text, explanation, information or whatever. This looks silly, don't you think so? Does your request has to do with the ledring or using the MSP-EXP430G2? If it is just about a project with CSS with the MSP-EXP430G2, create a new topic. greeeg 1 Quote Link to post Share on other sites

greeeg 460 Posted June 25, 2014 Author Share Posted June 25, 2014 PCBs are in! this is dubbed the ledRing G2955, (really just rev. 3) I bought solder paste masks for these, because I've been using them in other projects and are really worth the time, especially for QFN, I used to use hot air and this method is alot quicker. I will test these in about a week once I order the G2955 MCUs that they need. These use the tagConnect to program, and they connections are the old, ones, which have since been changed. I think another version needs to be made to correct this. I will add a footprint for the older style 4 0.05" because I know that tagConnect cables are expensive (and hard to buy, digikey hasn't had stock for ages ) Quote Link to post Share on other sites
Lord anubis 1 Posted June 25, 2014 Share Posted June 25, 2014 Just a question, why not just one type of ring design? the part that has/need the mcu with the other elektric parts will morphs that ring element as the master. When there are no parts there is no connection.. Not cheaper? Only need one designed pcb to order. Quote Link to post Share on other sites

When there are no parts there is no connection.. Not cheaper? Only need one designed pcb to order. I take it you mean why do you need 4 "dumb" boards and 1 "smart" controller board. I just think it looks neater BUT! never fear, because the "smart" controller board has a feature built in, short out these pads, or install a small resistor, and the controller section is bypassed. do this to 4 of the boards and you can make the ring with the one design.

zeke 693 Posted June 25, 2014 Share Posted June 25, 2014 @@greeeg, I have some ideas for how to connect the ring segments together. If the pads at the end of the boards had a via in them then you could take a pin from a right angle header, solder it into the hole, bring the two boards together. lay the pin across the pad of the mating board and solder it down. Another idea would be to add a right angle connector set. What do you think? Quote Link to post Share on other sites
greeeg 460 Posted June 26, 2014 Author Share Posted June 26, 2014 @@zeke, Hmm, I like your ideas. The current connection method is to lay a straight header pin across 2 boards and solder it down. I put in the vias to help with strain relief, I have seen too many SMD pads ripped off on past boards. Currently they're not large enough to fit a right angle header connection I don't think I'd be able to make them bigger since the LEDs are soldered right behind.

zeke 693 Posted June 26, 2014 Share Posted June 26, 2014 You may be able to put a via in the pads on both sides of the junction and then bend the right angle pin once more to make a U shaped pin then solder it into place. I have done that frequently in my prototyping. You may be able to use BUSS wire at that moment. It's just solid core [18..26] gauge wire with no jacketing on it. You just spool it off, cut it, bend it and solder it in. Quote Link to post Share on other sites
greeeg 460 Posted June 26, 2014 Author Share Posted June 26, 2014 @@zeke I'll look into that. I have had a bit of interest via email for people wondering about a kit/ something they can buy. So I made a placeholder on tindie. I plan on selling these off in small limited quantity batches if the interest is there. I haven't actually built and constructed one of these new versions yet, so it might end up being cheaper. https://www.tindie.com/products/Greeeg/ledring-clock/ Quote Link to post Share on other sites
Fred 453 Posted June 26, 2014 Share Posted June 26, 2014 If there are small vias on both sides, could you run a fine wire (maybe a single strand from some multicore wire) through both, twist it together and then solder over the top? It would add more strength against pulling the segments apart and less against flexing them, but should work OK. If you really want strength, maybe do this and the straight header pin.
