Tim240z Posted June 6, 2003 Share Posted June 6, 2003 I just received all the parts for my MegaSquirt unit from DigiKey (holy cow...lots of little things to put together ) and also got this email from Digikey: You have purchased the following part number(s) from Digi-Key within the last two years. The manufacturer has announced this part(s) will become obsolete. FAIRCHILD SEMICONDUCTOR (VA) Description: TRANSISTOR AMP NPN GP TO-92 CASE Manufacturer Part No: PN2222A_D26Z Digi-Key Part No: PN2222AD26ZCT-ND Your Most Recent P.O.

fastzcars Posted June 7, 2003 Share Posted June 7, 2003 WOW. Digikey really has there act together. Keep us posted on that megasquirt. I'm thinking of going EFI myself. But I'm EFI challenged. Quote Link to comment Share on other sites More sharing options...
Guest eric-z Posted June 7, 2003 Share Posted June 7, 2003 WOW. Digikey really has there act together. yeah, they really do. I sent the order for my parts in the morning last thursday and I got an email saying they had processed the order and sent the parts 2 hours later. eric Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted June 7, 2003 Share Posted June 7, 2003 Oh give me a break - a TO-92 2N2222 transistor! Those will NEVER go away, they are the building blocks of the industry. I wouldn't worry about that part, someone will always make it - you can get those off-the-shelf at Radio Shack. Quote Link to comment Share on other sites More sharing options...
Drax240z Posted June 7, 2003 Share Posted June 7, 2003 Digikey is one of the best companies I've ever dealt with. Talk about the right way to run a business. Highly recommended. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted June 7, 2003 Author Share Posted June 7, 2003 Can any of you guys give any tips on constructing the MS hardware? Any points in the process tolook out for? Any specific tools that would make life easier? (I assume a soldering iron and solder?) I have the box full of a million individual bags of electronic parts, and I have never tackled anything this 'sensitive' before.... Any help/advice would be very much appreciated! Thanx, Tim Quote Link to comment Share on other sites More sharing options...
fastzcars Posted June 7, 2003 Share Posted June 7, 2003 Hi Tim. I deal with electronic board repair on a daliy basis. I've looked on Megasquirts website, It doesn't seem too, too difficult. At least I can read the schematics, that helps. PM me. Quote Link to comment Share on other sites More sharing options...
Xander Posted June 7, 2003 Share Posted June 7, 2003 I just built my MS to go on my 260Z. If you just follow the assembly guide at this place you should be fine. http://members.shaw.ca/megasquirt/manual/mass.htm this is what I did. The first thing I soldered was the 37 pin connector. And guess what?? I used the female side which is supposed to go on the stimulator board. I had to desolder 37!!! pins. Also hook up with the mailing list. You can always ask questions there.

Tim240z Posted June 9, 2003 Author Share Posted June 9, 2003 What did you guys use for a box, or enclosure for the completed board? Is it something that I can find locally? I can't seem to find any info on the box at any of the websites. Thanks, Tim Quote Link to comment Share on other sites More sharing options...
Guest the_dj Posted June 9, 2003 Share Posted June 9, 2003 Here's a replacement, though the discontinued item seems to have PLENTY in stock still.

z-ya Posted June 9, 2003 Share Posted June 9, 2003 When I built my MS, I did the following: Print out the BOM (bill of materials). D ownload the manual, and print it. S tarted at the top of the BOM, and work your way down. Each time you install a component, highlighted it as such. Did you buy a preprogrammed processor? If not, you will need to find someone to program it for you. Once the processor boot loader is programmed, you can download new firmware releases as they come out. Since mine is going in a track car, I plan on keeping it simple, and just using the "off the shelf" firmware. I don't care about IAC (idle air control), or cold weather driveability. Anyway, keep us informed about your progress. Pete Quote Link to comment Share on other sites More sharing options...
Tim240z Posted June 9, 2003 Author Share Posted June 9, 2003 Pete, Yes I got the pre programmed processor from Bowling. What box did you use? Will I be able find something locally, like Fryes or Radio Shack? Is there a picture somewhere that I can take with me to show them?

z-ya Posted June 9, 2003 Share Posted June 9, 2003 I can't seem to find an email from the company I bought the boxes from. Nothing fancy, just needs to be able to house a 4"x6" PCB, with about 2" of height. Fryes should have something. Bring the MS PCB with you.

280Zen Posted June 11, 2003 Share Posted June 11, 2003 I ordered the box they recomended on the website, cost a bit more but it will look very nice when done. The website has a complete set of instructions on building the kit, which components to install first, a few simple tests after each stage of assembly to test that section. Just make sure you assemble the parts in the correct direction such as resistors and such. Quote Link to comment Share on other sites More sharing options...
z-ya Posted June 11, 2003 Share Posted June 11, 2003 Actually, the direction in which to inastall resistors does not matter (resistors are non-polarized). Polarized capacitors (ones that have a + or - on them), absolutely need to be installed correctly. There are only a few capacitors on the MS that are polarized. Another thing to keep in mind, especially when handling the processor, is avoid static electricity. The processor is made from a CMOS process that is static sensitive. If you zap it with static electricity, you can damage it. The pressure sensor may be sensitive too. Use one of the anti-static bags you get from DigiKey to keep your MS PCB in until you get it in the enclosure. Also, before you touch the board or processor, touch something grounded first (computer chassis, metal outlet box, etc). Pete Quote Link to comment Share on other sites More sharing options...
280Zen Posted June 11, 2003 Share Posted June 11, 2003 WooHoo, just got an email, the last part of my order from digikey is on the way! Looks like Ive got some assembling to do! Quote Link to comment Share on other sites More sharing options...
Guest eric-z Posted June 12, 2003 Share Posted June 12, 2003 yeah I got that same email about the rest of my parts from digikey, but I still have to wait for the partial kit. Quote Link to comment Share on other sites More sharing options...
Guest eric-z Posted June 14, 2003 Share Posted June 14, 2003 I received my PCBs today, almost ready to get started... eric Quote Link to comment Share on other sites More sharing options...
