Hello! Miss Sewing here. Mr. Sew’s been bugging me about posting his project for a while, and I, being lazy, told him the only way it was going on a blog was if he wrote it. And well, he did. His first-ever-wedding post is below.**
Hello, this is Mr. Sew. Since the table numbers are making Miss Sewing run about without her head attached, I have decided to write about our cake topper.
As we have mentioned earlier, our cake will have power poles going up the side with a street lamp lighting up the happy couple…. and what could go better with the model train power poles, then some model train streetlights? All I need to do is switch out the wall plug with some batteries and we’re good to go, right?
This is easier said than done, apparently. While they look nice, they were notoriously inefficient… and needed a whole 8-pack of AAs to light up, which looked kind of silly. So I had to do a few things to
salvage improve the design.
First I swapped out the old bulb with three LED bulbs which were brighter and took less power.
Everyone loves LEDs.
Unfortunately you normally cannot hook up LEDs directly to the batteries, since they need additional electronics (a constant current source for those of you who care) to function properly. Since I had to design the electronics myself (and because this was more fun than making escort cards), I decided to add a boost converter, so it only needs 2 batteries. (And I made sure that the whole thing was 100% lead free.)
And then I fit the whole thing inside a mint tin.
Curiously shocking mints
Finally, I took the topper, poles, some thread and cardboard, and put together the mock up to show Miss Sewing.

All lit up!
Did you have a “personal touch” added to your cake?
