The link is to a multi-raspberry pi setup I have for photo collection, content management, data management, service, and client code. Just playing around with different source code and system layout.

Yes, I’m still around, just haven’t been doing updates here. Hopefully I will get restarted. In the mean time, I’ve been prepping some stuff for the holiday decorations around the house. This first setup is a combo of projects that are available from Steve Good at www.stevedgood.com/catalog/index.php definitely worth looking at. I took the primary and merged it with his candle lit pumpkins project to get this setup in place!

Update in the Optune section…

I ran with mine on the “recharge” batteries for the past week+. The one thing I have to remember to do is repeatedly turn on the charger. The little battery in the monitor charges, and that tells the external recharger to stop charging. I found a little charger battery… [read here]

Ok, I’ve found another change that I’m including in this BIM thing. In addition to the sound being issued, I’m going to put in a parallel yellow LED to be flashed as well. Then I should be able to reinforce the condition when the optune TTF field generation isn’t able to run. And I got to demo the device on the Adafruit show and tell episode last night. Check’em out at Optune “add on” (the page)

  The little battery kept a charge almost all night long. I had turned off the “Brian’s Idiot Monitor” (like that name?) and just let the battery hooked to the charger board. The external battery charger i disconnected and plugged into the wall to reload.

Today i noticed that when i was outside in sunshiny weather, if i had the bag in yhe sun and the ttf still off, it didnt detect it. Just shading it a bit brought the BIM beep back on – so i plan to monitor the values frim the sensor to see if i can tune it better. We shall see!

Tommorow I’m teaching a chip carving class, so i may not get to play with this again until later. I can try to build a wood container to hold this device, if my student(s) make good progress. I can carve the case to personalize it while on my duke checkpoint early next week.

Although, I’m programming arduino from raspberry pi so i can take the little set with me to duke university’s check point… Hmmmm 

Well, I reduced the size of the unit over all. Then because the 9V lasts about 3/4 a day, I put on a remote power supply. You can see the RavPower supply as the primary power box (it also plugs into the wall and charges while it keeps running. And inside the “tube” where I tried to fit the kit is a small lithium battery to keep the unit running when the I replace the external power. The red button on the top of the tube is the on off switch for the detector. And of course, it doesn’t all fit into the plastic tube for the pen kits I had, so I’ll have to work up something else in that regard. However, I think the power supply may be sufficient to carry on for a bit. We’ll see… meanwhile the video is here.

I kept making different shapes and trying different approaches to making the bottle openers using simple approaches. The following two actually did use the lathe to provide the body shape, but could have been done with a scroll or band saw (or any other curve cutting saw). The focus on these two is really on Christmas – so I used the basics for the idea – a snow man and a tree.
