@@ -126,3 +126,63 @@ reflow myself? Even if I can barely manage, what qualification do I have
 to teach other people? Perhaps I should have picked my battles and went
 for a simple SMD hand soldering workshop instead. That's much much easier,
 and I have done this three times.

+## 2023-03-22, Wednesday
+
+As I rose from bed I realize I could have ordered 5 stencils, and
+organized two or more sessions in series. But I guess 10 is ok. Especially
+when imbursement is possible.
+
+Was busy most of the day, and I forgot to contact that shady vendor.
+
+After dinner I moved what I have got so far to the hackerspace with my
+bicycle.

+
+▲ It was a 2.5 km ride.
+
+In the empty hackerspace I unboxed the hotplate:

+
+I rang 聚源鑫 to ask about the availability of ATtiny48-MU, the cheaper
+alternative to 88. They don't have any.
+
+Now that the hope of getting chips from shady sources has vanished,
+I returned to LCSC to check out their offers. They are able to act as
+a broker between me and Mouser, charging 12.87 RMB apiece. Sounds good.
+I ordered 20.

+
+The much awaited stencils are here! They were sandwiched between two
+pieces of pretty rigid cardboard. The PCBs are in the same box.

+
+The major chunk of my BOM is taken care of. Now we shall focus on the
+nitty bitty discrete parts, such as capacitors and resistor packs. As
+always they are extremely cheap.
+
+Last time I forgot to give LCSC the invoice info eligible for
+reimbursement, so this time I ordered 20 more piezo speakers with the
+info. Totally necessary and not abusing the hackerspace funding.
+
+## 2023-03-26, Sunday
+
+The discrete parts have arrived.
+
+Also I brought all the tools I have from home: multimeter, soldering iron,
+solder, flux, etc.
