-Wish list:
-^ Item ^ Needed/suggested (USD) ^ Why ^ Notes ^
-| Sponsor a chip image! | 20-100 | Moar data! | Non-commercial only, you provide IC.  Usually top metal as delayering requires some to a lot more work |
-| Second CNC microscope operational | 350 | Increased throughput | Need BH2-HCL, LH50A to complete second BH2-UMA |
-| Keep the lights on | 75/year | Prevent canceling website when I need beer money | Free hosting offers are appreciated but will be politely turned down |
-| Real SSL cert | 200/year | Makes your browser happy | Tried StartSSL but they didn't get back to me |
-| Mitutoyo Plan Apo 50x objective | 800? | Better images, relieves imaging constraints | Assuming one pops up on eBay.  Olympus 50x ULWD clearance issues |
-| Confocal microscope | 2,000 | Much easier automated polygon capture | Typical industrial auction price |
-| Better lapping machine | 2,000 | Faster/better/safer delayering | Used price |
-| Gold sponsor | 1000 | Because you love me?  Selfish advertising? | Get your company logo on the site? |
-The server isn't free, the equipment isn't, and my time is limited.  I enjoy sharing information but its encouraging to know people appreciate it.  If you donate I'll be more than happy to help you out by working on an article of your choice or imaging something of your choice.
-If you have some interesting chips I'd probably take them to image as well.  Be warned though I have quite a stockpile (ie backlog) of chips already but I'd like to help others out to spread interest.  Be warned that I'm less likely to help you gratis if you have commercial interests
-====== Sponsoring a chip ======
-Consumables used for every chip:
-  * Acid (typically H2SO4 or WFNA)
-  * Filtered canned air
-  * Acetone
-  * IPA
-  * Deionized water
-  * Paper towels
-  * Gloves
-  * Electricty
-  * Stuff ocassionally breaks! (eg glassware)
-None of these are bad by itself but add up.  The equipment also ain't cheap and would love it if someone could help me offset the costs.  Also it adds up to a few hours per chip to go from epoxy package to stitched image
-Delayering ranges from dangerous to very time consuming.  HF will work decently for most single metal chips but is a little dangerous to work with even at low concentrations.  Also at least a couple of hours work for good results.  Lapping generally produces good results but is very time consuming, say 8+ hours of work.
-====== Second microscope ======
-Have:
-  * Heavy duty motorized XY stage w/ rotary encoders + glass linear encoders + motor controllers
-  * Spare high quality microscope base for XY stage
-  * Most of a BH2-UMA
-  * Unused NeoSPlan objectives
-  * Extra STM32 to turn into indexer
-Need:
-  * BH2-UMA missing BH2-HCL (~$50) + BH2-LH50A (~$150)
-    * A lower quality illuminator would discourage its use
-  * A table in the garage ($50? free on craigslist?)
-  * Leveling mechanism: may be able to scrounge from existing stockpile but more likely $150
