Auction Purchases: Items for sale and other

So here's what's for sale. I have omitted some things as it really isn't worth the time to sort and ship resistors/connectors/etc.

I live in Kansas City and go to KSU in Manhattan KS so face to face deals would be more than welcome. If you are uncomfortable dealing directly I can put stuff on eBay for you at a pre agreed buy it now price.

No reasonable offer refused, just look up retail and take a good percentage off.

Mid to upper hundreds of standard power Whites
sack of 8mm blue
sack of IR 5mm
sacks of various "high brightness" standard power whites and many loose
~500 "Piranha" style RGB LEDs $0.20ea

After taking this picture I still kept finding more bags of LEDs

Pic 2: Steppers
These are relatively self explanatory, tinys, NEMA 17 , NEMA 23, NEMA 34

The largest 3 are labeled 42-8A  in a NEMA 34 frame, these suckers are BEASTS. If I could justify it I would probably build a giant plasma table with them or a robot with rather deadly intentions. They have so much torque I almost wonder if they could drive the E-Bike...
 
The tub with what looks like rolls of coins is actually full of sealed skate bearings, ABEC-7 concentrically rating, 10pc per tube. Perfect for Bots or CNC.

A couple things I forgot to add to the table were 5 ball nuts for high precision ball screw linear motion systems. As with the LEDs as I keep going through the boxes I just keep finding more and more, no more big ones though. There are also 3-4 Meanwell PSUs that would be great for all but the largest steppers.

several others I dont recognize

Also a basic beagle board not pictured. Not sure what they are worth due to competition with RasPi but taking offers

Pic 6: NOT FOR SALE, SORRY THIS BABY IS MINE

Beefy PSU, 36v 25A. Not as large as 1.8KW supply, only weighs as much as a single sack of concrete instead of two though. Only paid $16 for this bad boy and it works great other than the fan was shattered but I already had a replacement

This is the bulk of the ICs. They were all dumped in a big tub so I had to sort them out of a bunch of other stuff so that I would then sort each IC type from another. What I did was just sort 1/3 of the chips in the tray and use that to estimate the total number of chips I have.

100x Ti 07A612M SN75441one Half H Driver $1
50x Philips 74HCT04N inverter $0.15
25x MSP430G2231 MCU $1
6x MSP430FG439 Low Power MCU $5
30x 386BD Audio Amp $Offer
45x P82871SPN Signal buffer repeater I2C extender
50x L620SD Motor Controller Dual Full H Bridge
30x VNH25P30 Half Bridge Motor Controller
7x SLA7032M 2 Phase Unipolar Stepper Motor Driver
100x JC79RA LM1084 5v LDO Regulator $1.50

Pic10: Bot Parts
Pictures is labeled pretty well. Tons of bot parts for bots or CNC. Not going to go into high detail but there are ~12 IR distance sensors, 6 Line sensors, and ~8 "Photomicrosensors". And a bottle of Aspirin for when things get real tough.

Most of the good stuff at the auction went pretty high, This is stuff that came out of the large lots that I bought.
2 large DC supplies. Shortwave radio antenna kit from radio shack. Divider box has about ten different values of caps in it plus some crystals and chips I didnt check out. DC to DC "TX" PC power supply boards, Along with the irons shown I also have another half dozen Hakko 936 solder stations some with and others without pens

There you have it, let me know if anything catches your eye, yes I'm trying to make a bit o' money but I like helping others afford their own projects as well .

Happy Hackin,
