chemicals and equipment (near the Sunnyvale library)
Chemicals (powder): ZnSO4 SnCl2 CuSO4 MgSO4 Mg strip + mixing bowls, 25 ml graduated cylinder, filter paper. Not flammable (except for the magnesium strip) or highly toxic, but you should be familiar with safe practices in inorganic chemistry, and have appropriate gloves and protective gear!
Free:
small indoor refridgerator (near the Sunnyvale library)
Gifted
Proctor Silex PSR17MBKE fridge, about 17x18x18 inches, not fancy but works fine. I used this in my office for drinks and lunch supplies. The door rack supports small drink containers, but you can not fit e.g. a large milk carton in! Support table also available, but just fits; the fridge will fall off if you push it too far.

Free:
DC power supply (near the Sunnyvale library)
Gifted
TekPower TP1503C 110 VAC to 0-15 VDC, 3A power supply. Old but doesn't appear to have ever been used.

Free:
alumina powder (near the Sunnyvale library)
Expired
Three jars of 3 micron alumina powder, that can be used for high-precision polishing. Several years old but sealed, should be ok.
27d
Free:
felt-covered pressboard (near the Sunnyvale library)
Expired
Felt-covered pressboard tabletop, about 36" x 60" (3x5 feet). You will need to bring a vehicle to carry this away in, it's heavy!
55d
Free:
Behr white interior paint (near the Sunnyvale library)
Gifted
About 1/2 can (?) left over from a bathroom remodel a few months ago.
62d
Free:
Marazzi Porcelain Floor/Wall Tile (near the Sunnyvale library)
Expired
A full box (8x(12-25-5/16 in)) porcelain floor and wall tile, plus several loose pieces as shown in the photo. These are left over from a bathroom remodel -- not used and in good condition.

Free:
Microsoft Ergonomic 4000 keyboard (near the Sunnyvale library)
Expired
Worn but functional: covers on handrests are eroded, and some key labels are not legible, but the keyboard itself still works. Old-style USB interface. I used for Mac, should be fine for Windows too.
100d
Free:
kneeling chair (near the Sunnyvale library)
Gifted
Can be useful when you have a back strain or soreness that is exacerbated by sitting in a regular chair. One wheel attachment repaired but still works fine.
204d
Free:
Zep shower cleaner (near the Sunnyvale library)
Expired
Purchased this and followed the instructions to test -- found that it discolors my shower wall! so can't use it. Hardly worth returning at the store, can give to anyone who is local and uses this for their fixtures (but you should have tested it!).
226d
Free:
Omega HHM12 multimeter (DMM) (near the Sunnyvale library)
Gifted
Omega HHM12 digital multimeter; DC and AC voltage to 600 V; resistance ohms to 2 Gohms; diode test; continuity test; capacitance microF to mF; thermocouple temperature. Display has a few scrapes and scratched, but seems to work (might need a new battery soon).
259d
Free:
Adesso wireless keyboard (near the Sunnyvale library)
Gifted
Adesso WKB-1150CB wireless keyboard. Ergonomic design, easy on the wrists. As far as I know, it works fine, but I lost the USB dongle, so you need to have a USB dongle and pair it to the keyboard (see ).
265d
Free:
LG Ultrafine display (near the Sunnyvale library)
Gifted
Nominal 23.5" 3840x2160 LG Ultrafine computer display. Note that this uses the Apple style USB C/Thunderbolt connections; if you use HDMI, you'll need an adapter.
266d
Free:
18650 battery packs (near the Sunnyvale library)
Gifted
Packs for 18650 batteries (lithium ion) -- two each of 4-pack, 3-pack, 2-pack, one 1-pack. If you provide an address (preferably in the San Francisco Bay Area) I'll just ship them, or we can meet at the Sunnyvale Library.
268d
Free:
Brita filtered water bottle (near the Sunnyvale library)
Gifted
Brita filtered water bottle (used up the filters; they are available at e.g. Target). Fill up the top with tap water, drip to the bottom thru the filter, then have nice clean water. A filter lasts around 3 months.
269d
Free:
foam core 20x30 inch (near the Sunnyvale library)
Gifted
Foam core, 3 white and 1 black, 20x30 inch, useful for e.g. a kid's science or art project. A few of the corners are slightly crinkled but otherwise in good shape.
269d
Free:
portable air conditioner (AC) (near the Sunnyvale library)
Gifted
Vissani VPFD05CLW indoor portable AC, with window interface, tubing, instructions, remote control. Good shape, worked fine the last time I needed it (a few months back in autumn). This is placed near a window using the tube to connect the AC to the window insert (so the hot air has a place to go). It provides enough air to cool a work area or small room.
269d
Free:
shelf+cabinet on casters (near the Sunnyvale library)
Expired
Wooden shelf with a small two-level cabinet below, on casters for easy relocation. Dimensions given in the first image -- it's pretty big, so you will need a truck or big car to pick it up. Fairly good shape, though could use a bit of cleanup. Pickup probably best before the library opens, so that the parking lot is fairly empty and you can just pull up next to my car.
273d
Free:
Tech-Play vinyl record player (near the Sunnyvale library)
Gifted
Plays records onto e.g. USB stick. I haven't used this in quite a while (as is evidenced by the dust) but I think it still works. Comes with power supply.

Free:
Apple Thunderbolt Display (near the Sunnyvale library)
Gifted
Thunderbolt Display 27", 2560 x 1440, 30 bit, Thunderbolt/Displayport [includes USB C adapter]
278d
Free:
Duxtop Induction Cooktop (near the Sunnyvale library)
Gifted
Model BT-M20B / 9100MC. This is an electric induction cooking station. You need appropriate pots or pans (some work, some don't: if you put a pot on that will not work, the cooktop recognizes it and gives you a notice). You can set a power level or temperature; I typically used temperature settings. Slightly used; worked fine, but my family was not interested.
307d
Free:
monocular microscope (near the Sunnyvale library)
Gifted
Technical Instrument 607905 monocular microscope; 4x, 10x, 40x objectives and unlabeled (presumably 10x) eyepiece. Dusty but seems to be functional. Does not come with a light; you would need to add something to illuminate from on top or below, depending on what you are looking at.
341d
Free:
Spacewarp toy (near the Sunnyvale library)
Gifted
This is a toy for kids who like to build things. It sat on the shelf for many years and is pretty dusty, but I verified that the rotating loaders still work (although you should clean them carefully!). I will provide a new pack of 4 batteries as well. Lots of extra parts supplied for making more elaborate stuff than what is shown.
349d
Free:
The Story of Civilization books (near the Sunnyvale library)
Gifted
Will and Ariel Durant's The Story of Civilization, a classic history of (mostly Western) civilization, five volumes: Our Oriental Heritage, The Life of Greece, The Age of Faith, The Renaissance, and the Age of Louis XIV. Used but intact and in good condition, fine for reading.
351d
Free:
Bluetooth Low Energy Gateway (near the Sunnyvale library)
Gifted
PTS Bluetooth Beacon Gateway model G1-E (purchased for some experiments, very slightly used); if you're local we can meet at the library, if anywhere else in the US I will ship by ground...

Expired
Universal detachable tablet wall mount bracket for iPad/Samsung tables, 7 to 10.4 inches. You can use this to attach a table to the wall or anything else you'd like.

Free:
mounting rack, DA-5C eBike Battery (near the Sunnyvale library)
Expired
I have two mounting racks for Atlas DA-5C eBike batteries (not the batteries, just the racks). These are unused and in good condition. If anyone needs one or both, I can ship if in California.

Free:
"Alfred's Group Piano" book 1 (near the Sunnyvale library)
Gifted
This is a 350-page binder book (presumably so it's easy to use on a music stand or piano), in good shape; book 1 of what is presumably a series. It would be useful for someone who is serious about learning to play piano.
