What is the weight of the device with the alu body/ back cover?
2. Anodizing: rollercaster again. We were happy already, as we found anodizing shop that accepted our requirements without complains, on good price, and promised that all our recent problems are of no importance, as "they will handle it internally", till results are satisfactory. After a week, when Estel was due to pick up anodized prototypes, they returned it back in vanilla state, demanding new holes in unacceptable positions (for placement of thicker wires, than handle current during anodizing). On a good news side, we got something that seems like awesome suggestion - friendly OpenPandora hardware modder suggested using so-called ceramic lacquer, heat-hardened variant. The thing that is used to paint calipers in high-end (or tuned) automotive mechanics (brake parts). Said lacquer is supposed to have sky-high mechanical (scratch) and heat (up to 480 C degrees) resistance, corrosion protection better than anodizing (including resistance to various acids, salts, etc), and is available in the same array of colors. It require purchasing in larger quantities to be economically feasible, but then, it's no more expensive than anodizing. Another plus side is that we could apply it on our own (including the hardening part, which require heating and cooling object in few cycles, up to few hundreds C), without relying on 3rd parties. We ordered a small quantity sample (VHT Caliper ceramic lacquer matt black, to be precise) and we will conduct test after receiving it (no sooner than in the two weeks after 28 June, due to mentioned vacations).
