Post by thread:need PIC16F877 in SF Bay area (10-12 April) !!!

I have a PIC16F877 which just got fried and I've ported my application back to my PIC16F84, but I would prefer to get another PIC16F877 today or tomorrow because I am close to the very limit of the 'F84 1K internal program memory limit. I'm in the Sunnyvale/San Jose, CA area days and San Francisco evenings. The application must be complete for an art show opening on 13 April in San Francisco. Can anyone let me know where I can zoom by with my car and pick one up in this area? Price is not so critical. cellphone: (415) 254-4545 office: (650) 584-5591 Help is greatly appreciated! Thanks in advance, -chris P.S. We are creating a large-scale art installation using 2 x Polaroid 6500 ultrasonic sensors and 60 DC electric motors to control this interactive art work. I created a system which expanded the I/O of the PIC16F84 to 120 inputs and 120 outputs using a 4-wire serial link via 8-conductor LAN cables (differential pairs using AM26LS31 and AM26LS32A). It's very cool (if it works). The PIC talks to a Macintosh via s/w UART (or '877 h/w USART). The Macintosh is running MAX MIDI software from IRCAM to control this whole thing. We are still having problems with the 6500 sonars. We have tried many things to get them to detect up to the advertised 35 feet. All tries have seen a distance limit of 19 feet. Any hints are welcome. Contact me if you'd be interested to see this or help me get my last bugs sorted out!

Chris, If you can't find one in your area, try Digi-Key (http://www.digi-key.com), they stock the DIP and PLCC versions and can ship overnight (you can try for same day) to most of North America (even to us up here in Canada).

I've got one kicking around here somewhere, but I'm in San Diego. I could fed ex you one. I did a similar project when I was in college (not nearly as complex). It consisted of a face that had articulated features (eyes and mouth) that would change expression based on how far away you were from it. I didn't have the dough for the polaroid ranger so I used IR interrupters. When a viewer would walk closer to the face it would smile. When they walked away it would frown. My stepper motor driver was a couple of relays which would unfortunately cause the PIC84 I was using to reset occasionally causing some really strange expression to come out. All the art students thought my face was artistically horrible, but when they turned it around and saw the balsa and kite string counterbalance arrangement they thought that it was really cool and said this and that about the human condition. As a result my face was displayed facing backwards.... Let me know if you still need the 877 and I'll drop it off to fed ex. this afternoon.

Fry's doesn't carry PICs ... I asked them (Arques Ave store). -chris At 03:17 PM 4/10/00 -0400, you wrote: {Quote hidden}>You may want to try Fry's Electronics >550 E.

Thanks, I'll try to find one here, but check again at 5pm today if nothing else turns up. I'd need 10 MHz version. -chris more later.....
