Only in England. Scots speak of "jelly pieces" (=jam butties to you).

BTW: trifle with jelly/Jell-O is an abomination acceptable only at young children's birthday parties, but that's another discussion altogether... I'm still in detox after my cousin made grandmother's trifle recipe at Christmas. Too sloppy and tiramisu-like for my taste, but pretty good anyway.

I usually find myself agreeing pretty strongly with Symon about electronics, but it seems we part company about gastronomy :-) Toast-racks are better described as "toast coolers". The ONLY way to eat toast is very soon after it emerges from the grill, which is why breakfast-time toast in English hotels is always such a disappointment.

I should know better than to trifle with toast.

I did in fact consider 'marmalade applicator', but thought that 'jelly' would provide us with more breakfast language fodder.

I suspect one impediment to the widespread adoption of British Toaster Technology in the American kitchen is that the heated toast racks require a high-amperage DC supply having positive ground.

And we drive on parkways and park on driveways. And we "pre-drill" and "pre-heat". ;)

Weird, I've been here a few years now and not heard that one. I think "jam sarnie" is the local vernacular I'm used to. I believe all this terminology is compliant with the EEC standard for Jams, Jellies and Marmalades (and sweetened chestnut purée):

Jam is like Jelly but created by a team of engineers: You can have it yesterday, tomorrow, but not today :-)

And special people get to "pre-board" an airplane!

I don't know which is more intriguing: a cereal named Elijah's Manna (Now With 18% More Piety!), or the fact that Post Toasties has its own entry in Wikipedia. Truly, we are a species with too much time on its hands.

I plan to create training movies on how to do SMT board assembly, SMT rework, and SMT repair. Any interest?

Now all you need is a Gerber-driven solder paste dot printer! They exist, and news of an affordable unit for prototyping would be interesting.

Following up myself, the Essemtec CDS6700 solder paste printer seems to cost around $25,000. Not quite affordable ;-)

Makes me wonder what it would cost to build x-y table and reuse a inkjet cartridge ;)

Do you think the solderpaste would get through the ink channels ..? Maybe it's viscosity is too high.

I also think that any ordinary underpriced inkjet will be just fine. Just bring the screwdriver. On a more serious side, increasing the distance between printheads and printer bottom. Then add some wagon to fasten the pcb into which is driven by the paperfeed mechanism.

I think the real blocker is the ink channel mechanism, once that is solved it depend mainly on precision of x-y table + diameter of the solderpaste drop.

How about an old scanner, turned upside down, with the optics replaced by a paste syringe, pumped by either a stepper motor & leadscrew, or by something generating pulses of air pressure (which is how the professional rework stations do it)?

Add a printer "x-drive" to the scanner and the x-y is complete. Syringe pumped with leadscrew might work, albeit possible slow. The air pressure approach together with a magnetic valve may also work.

What do you think about a combined camera + very thin soldering iron to completly rid of the oven stage..?

Yes that may be a big problem. Maybe something could be done to make the paste more suitable.
