For your viewing pleasure
It is that time of the year...NO! Not my annual shower, but Christmas. Rachel recorded me and my rest of my trio messing around at small group. Some modernizations of some classics.
Back in the swing of things
Since, I've been back I have been busy at work at restoring the house. Tons of yardwork and exterior cleaning, car maintenance, etc...you know normal 'man' stuff. This last weekend was my first weekend I had time to roast coffee, so with my new Christmas present, I filmed the process so the few people who follow my blog or the random stragler can replicate it at home. Remember, home roasting is not to put professional roasting companies like Intelligentsia or Counter Culture out of business, because you wont and can't. But you will be able to make as good, if not better coffee at home for cheap. Enjoy.

Did you know?
The sucky economy has caused my mutual funds to climb ~30% since like 2 months ago. Granted its still ~30% lower from its all time high, but there has been great growth.
Also Rachel is starting to look pretty pregnant. See

Catching up Pt. 2
Then, after working on the yard. Rachel's food processor and blender broke kind of. So I fixed them both. Her food processor has got this button and a ridiculously over complicated linkage system of nylon/plastic pieces in the bowl handle and food chute that prevents the machine from turning on if the chute and bowl are chocked inside. Well the little pieces wore out and now the button would never press, therefore the food processor would never turn on. So, I opened it up and bypassed the switch. Not without first going to the hardware store and buying some tools to do it. SWEET! NEW TOOLS! Plus it was for Rachel so its a perfectly justified purchase. Now our blender we use a lot. More so than any normal human beings. Hey, its not my fault Rachel makes delicious pina coladas. That plus she uses it for a ton of other random things. So daily pina coladas, daily fruit smoothies, plus other random crap made the little plastic gear thing the motor spins break some teeth off. Alittle gorilla glue should give us another six months or so of trouble free blending (this has happened before and gorilla glue fix it for a while). I wish manufacturers would make these little pieces metal for psycho power users like us. (No pics, not that interesting)
Ok, now, my neglected PID/espresso machine project has gotten alittle love this weekend. I have a functioning circuit of the PID working with the boiler's heating elements. THE CIRCUIT WORKS! Just not reliably. It gets VERY hot. If you start it up, the elements turn on for a long time until the PID starts to modulate temp around 190F. So from 80F to 190F the elements are on pulling a lot of current through my homemade solid state relay board. So hot that it will start to boil and smoke the thermal grease between the thyristor and heatsink (thyristor being the component that carries all the current for the elements). This boiling degrades the thermal conductivity of the grease so much that when you turn off the PID and then turn it back on it will not conduct the heat to the heatsink and the thyristor will burn up. I lost a SSR this way, one is enough. To prevent this from happening again I needed an enclosure to house my SSR and provide air flow. Well I looked all over Guam for a sturdy enclosure for a week and found one at the arts and crafts store. It's an acrylic box that house a computer fan for air flow and is large enough for the fan, the relay board, two PID's, and wiring. This will be outside the espresso machine when finished and most likely be an eye sore but it will work. This bad boy set me back five bucks. Try not to be too critical of my lack of craftsmanship. As soon as I attempted to jigsaw a hole in the lid it pretty much exploded from the vibrations. It's thinner acrylic than what I am used to but I did manage to salvage most of it and it will still work.

Catching up
Yeah, yeah, yeah...It's been awhile since I posted anything. I've been busy like everyone has. But, I have caught up in my productivity this last weekend. The weather has been the worst I've ever seen on Guam this last week. Rain the entire week! No, you don't understand. It just about rained constantly the entire week. Maybe 10hrs without rain this week. From Saturday, August 1st to Friday, August 7th, nothing but rain. Fortunately out of nowhere, we were blessed by an entire weekend of little to no rain.
Rachel went out of town 3 weeks ago, and came back a week and a half ago. During that time I pulled some real long hours at work. Hence no updates during that time. Then she came back and we've been going out a lot so no updates, til now!
Last weekend we went wine tasting at Top o' the Mar. A restaurant ran by MWR here on Guam and we had friends over for a BBQ, sorry no pics of either event.
We didn't do much of anything throughout the rest of the week. I practiced for church on Thursday, two duty days, nothin' big.
This weekend I worked on my lawn. I had an area right outside my front door that was growing up whatever it could. So I killed everything living, laid some plastic/anti-weed wrap across it, put some scalloped pavers in as a border, and put bark down. Turned out awesome I think.

I'm gonna be a Dad!
Yes, my wife is very pregnant. 10weeks pregnant. Last Friday I took her to get an ultrasound and the baby is about the size of a large peanut, but has a heartbeat and is healthy. I am pretty excited, I don't care what the sex of the baby is. Here is the ultrasound results:

Past the point of no return
I have done it. I have gone all in. Bet it all on black. Past the point of no return. No looking back now.
I have completely gutted my espresso machine of wiring with the exception of 3. 1 Supplies power to both boilers, and then the other 2 are each boilers heating elements output to complete circuit. The thick white "wire" isn't really a wire at all but a thermocouple input to a PID controller (read on).
I have a picture so you can see what I am talking about.
Originally, it was a complete rats nest of wiring from the factory. It was seriously horrific. I like to think I am pretty competent about electronics, especially appliances and cars which are fairly simple creatures. But this wire job was unimaginably complicated and confusing. I would stare at it for hours and only be more confused after wards.
So I decided to go for it and completely rewire it the way I wanted to. Which brings me to a new challenge: Make the dang thing work! I may have bitten off more than I could chew by doing this. I took precautions before doing this like taking photos of the wiring before gutting it. However, the wiring was so bad, I doubt I really could ever get it back together. Rachel warned me not to do it (standard wife protocol), but she is secretly hoping I don't get it to work so we can get a new super-wamadine machine.
There was a couple things that led me down this route. 1. Stock components are starting to wear out. Like the brew boiler thermostat starting to heat too long, therefore turning itself into a second steam boiler. By the way, in case you were wondering, steam makes horrible coffee. 2. I wanted to have a digital PID temperature controller instead of a thermostat, but the PID does not play well with the contactor (not pictured, already removed). The machine's boilers would trip a standard 15A circuit breaker if they were both energized simultaneously, so a contactor/relay was wired in to essentially be a electro-mechanical power saver by switching power between boilers so they both can get hot but prevent overloading the circuit. The PID causes the contactor to cycle excessively and only the brew boiler gets hot because the contactor gets confused by the pulsing of the PID.
I believe, since the PID is a smarter way to go as far as energy usage goes that I could power both boilers without a switching device such as a contactor (since a PID is a switching device in a sense). This will simplify the overall wiring without the contactor. Then use the pre-existing switches to energize the pump and solenoid valves (orange thing and black box things respectively in the picture) as the factory originally intended. Read more about PID's here: link.
If I fail, then I am an idiot for ever attempting this hair brained scheme. But if I am sucessful, then I am a FRICKIN GENIUS!
At work I have a nickname that has to do with all my insane behavior, "Dr. Scientist". Mostly because of what I do at work, but it is a personality I have developed over the years. Sort of a Dr. Jekyll and Mr. Hyde split personality complex. Mild-mannered "me" transforms into obsessive-compulsive "Dr. Scientist" when it comes to my hobbies.
