  1. Well looking at the signals with the scope they both look fine. I Removed the cap and it works fine now go figure. Ok. I guess i am losing my mind. I looked at the hardware ref and Doh ! that cap is supposed to be connected to the rst line not the test line. It seems that i am going blind. And its supposed to be a .01uf not a .1uf
  2. I designed a board using a MSP430G2553IPW28R its the 28 pin tssop package. I read on this forum that you can use the launchpad to program the part I have some code written and can program a 20 pin device but when i connect the wires to my board from the launchpad is cant find the device or its not there. Error connecting to the target: Could not find device (or device not supported) I used CCS and just for the hell of it did the MSP-EXP430G2-LaunchPad User Experience Application example which programs just fine but i get the same error when plugged onto my board. Here is
  3. ok boards got here today i will be sending them out tomorrow i will let all of you that wanted one or 2 what the cost is tomorrow via email
  4. false alarm it was something else should be this week tho
  5. from the pcb manufacturing place Dear Customer, Thank you for your patient waiting, your PCBs has been manufactured, we have send it to the local logistics center. For DHL it may cost about 3-5 days, for Airmail it may cost about 15-25 days. Later We will send the tracking information to you, the attachments are the pictures of your products. Thank you! Best Regards Elecrow
  6. Boards have been ordered today as promised Amount:$60.90 USD for 10 boards plus $13.34 USD Shipping and handling SO 7.45 per board plus shipping. i have kitted up all the resistors and caps and the one led along with a 20 pin machine socket for the 430 ( for free ) also in the package i will include a BOM and a 11x17 schematic page. spirils -1 jpnorair -2 vicvelcro -2 JonnyBoats -2 geekdoc -2 please you guys send me your mailing address so i can address the envelopes and weigh them to see how much postage is I suspect they will be made tomorrow and if all goe
  7. yeah thats it oven is for any oven that has top and bottom elements and a convection fan i grabbed mine at walmart for 50-60 bux single element ovens will not work well as temp control will not be good enough and it also cannot heat up fast enough for the reflow profiles especially for lead free solders
  8. i can order as many as everybody needs in multiples of 10
  9. Well the first pcb was a bummer with a few errors but its been revised and i will be ordering up a new batch of boards with corrected placements. If anybody is interested in a board or 2 please contact me @ wulfman@wulfman.com before next thursday and i will make the order to include however many boards need to be ordered. Price on the boards are about 6 bux plus whatever shipping from china is divided by the number of boards i have made. I will ship all the resistors and caps with the board for free. Connectors for the board can be purchased on EBAY as well as the nokia displays. there i
  10. OK sorry for no updates. Due to a few errors and one big oops i will scrap this batch of boards. This is the first board i have made with Allegro all my past boards were made with orcad layout. There was a learning curve and even though it is easier there was an error in footprint pins vs schematic pins in the voltage regulator ( 2 and 3 swapped ) I swapped 2 pins ( MOSI AND MISO ) because of me not paying attention to the pictures on https://github.com/energia/Energia/wiki/Hardware. I used the pinout for the MSP430G2452 ( WTF? why would TI swap the 2 pins anyway ) I also noticed that my power
  11. yyrkoon told me that he has the boards now. unfortunately i had to go to nevada for a funeral then i need to go to tempe AZ so it looks like another week till i can get to checking out the boards and getting things together. ahhh the best laid plans of mice and men.
  12. IF i spec'd 2oz copper i could have used narrower traces but that chinese place dont use 2oz copper. oh the tradeoffs
  13. I have a question. Any people out there going to run this on 220volts ? when I did my AC mains spacing I set it to the US 120 volt trace spacing of 25 mills. I did not take into consideration that i would be even selling these to anywhere other than the US. I suppose in later versions I can space them out or make a version that has larger spacing and smaller trace width as 220 needs 1/2 the copper for the current. Just a thought I am sure that it would be fine for short duration usage and if you are worried you can trim the copper down a bit with an exacto blade. The 5 volt power supply i am u
  14. Ok it seems the PCBs were made. I hope they left china in time to not be held up by the Chinese new year. here are links to the finished PCBs on my web site. http://www.wulfman.com/reflow-back.JPG http://www.wulfman.com/reflow-front.JPG
