Yes, it really is a shame. Some of the items I buy from him are either very difficult, or even impossible, to get in small quantities at *any* price. Basically, Ed told me that the problem is as soon as a part gets a market, and no longer is 'pure unobtanium' material, a large distributor like Digikey will start selling the parts, undercutting him so much that he can't even move the inventory he already has. So basically, he makes a few dollars on the first few sold, and then looses money on the last few, and basically breaks even after handling all the paper work, inventory maintenance, packaging, etc. > Oh well, thanks for posting about the sale. Sure thing. Since there has been other interest, I'll include the small list I made to comp.robotics and sci.electronics here for you to see other parts being carried by him: ----------------------------------------------------------------------------- I just received my Pure Unobtanium flyer today and prices have been reduced drastically for a going out of business sale. For those not familiar with PU, it is a small company operated by Ed Nisley who writes the Firmware Furnace column for Circuit Cellar Ink's Computer Applications Journal (CCI/CAJ). PU typically carries parts that are difficult (or impossible) to obtain in low quantities - perfect the hobbiest types. Ed said he was closing down the business since it was just too much work for the small financial return. I think he only sent the flyer out to those individuals that have actually ordered parts from him, or contacted him in the last few months for a catalog. Since everyone on these two newsgroups may not get the catalog, I've included some of the best robotics/hobbiest type parts here: UCN5804B - unipolar stepper driver 50v, 1.25A ........ $2.60 UDN2993 - dual H bridge, 40v, .6A .................... $2.70 UDN2998W - dual H bridge, 50v, 2A .................... $5.50 PCF8574 - 8bit I2C I/O expander ...................... $3.20 PCF8583 - I2C clock, with 240 bytes RAM .............. $7.10 TDA8444 - I2C octal 6bit DAC ......................... $5.00 Chip sack 8031 (everything for a basic 8031 system) .. $6.00 87c751 - EPROM part .................................. $18.00 GP1U52Y - 40khz IR receiver .......................... $1.90 MT8808 - 8x8 crosspoint switch ....................... $6.20 MAX233 - 5v RS232 interface .......................... $5.00 MAX7219 - Serial LED driver (drives 64 LEDs) ......... $5.50 Power opamp (3.5A, +/-3v to +/-13v) .................. $1.60 UDN2585 - 8bit source (25v, 120mA) ................... $1.50 MAX691 - uP supervisory circuit ...................... $4.50 MT8888 - DTMF transceiver ............................ $4.00 SSI75T204 - DTMF receiver ............................ $4.90 DS1232 - watchdog, PS monitor, reset debounce ........ $2.50 and many more (6 full pages with descriptions). I have no affiliation with PU other than a past customer and acquaintance of Ed Nisley - I do *not* get a kick-back from this. However, if you do call because of this posting, please mention my name, since I am doing this as a favor to him.
