Looks nice!

I thought there were caps built into the RayTac board so I didn't need to add them

I think there are some bypass caps actually, but especially if running off a watch battery it helps to have something a bit bigger (>1uF) to take care of the small 'peaks' of current consumption.

Thanks... to bad the bubble displays are hard to come by and if, then exorbitant expensive, that's why I ended up with the clear-transparent module from National Semiconductor - new Old-Stock see conversation about Retro Bubble Displays driven with 74HC595 - I'm sure you were there already. At the time I played with it, I still could get 4-banks and single bubbles... but expensive as well. Nowadays I don't even find them on ebay anymore, not even from the places of the former UDSSR. Putting a red 'filter' over the transparent ones gives them almost the same look and (visual) feel.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.
