In any iterative process, it is nice to see progress. Recently, it was gravity model distribution (again), so I had a process in R to calibrate friction factors, and part of it exported the trip length frequency chart: ggsave(paste("TLF", Purpose, Period,…

I decided to build a Colpitts oscillator after watching one of W2AEW’s videos. The only issue I ran into was that I had the power supply hooked up backwards, so when I initially connected it to the scope, the +12V shorted to ground (and it burned a small…

Heatmaps are an easy way to look at data when you have a lot.  The heatmap below is from a 30 day traffic count.  You can easily and quickly see that peaks in the morning are northbound, peaks in the afternoon are southbound, and peaks on the weekend are…

So last week this happened: I spent an evening scrubbing – the kegs were reasonably clean inside, but the outside was a bit of a mess. PBW and an Ocello scrubbing pad were the tools of choice there.  I then proceeded to learn a few things, some of these…

Where I got started on this subject This all started when I saw a blog post on Practical and Low Cost Water Adjustments. The author there is pretty convincing on the importance of this. Following links from that site, I found this.  “Rerun” claims to live…

Some time ago I built an Internet gateway (iGate) for monitoring APRS packets and sending them to APRS-IS.  It never made it to the blog partly because it was built out of Direwolf, so it was mostly software configuration. Since then, I’ve had trouble…

From time to time, it makes sense to not re-invent the wheel by building something in R that is already available in another program, like Cube Voyager. This is incredibly easy: system("voyager.exe script.S /Start /CloseWhenDone") That’s it!  BUT… If you…

I entered four beers into the Hammerdown Brew Cup.  This is by far the most that I’ve ever entered into a competition.  These beers I feel really good about. Mesa Cerveza Vienna Lager This is from a recipe I copied and adjusted from Five Blades Brewing. …

This is the second part of something that has been sitting on my workbench. Part I. The video below shows the two traces of the input and the output of the second JFET. The board is coming together as much as it could be for not being printed or having an…

With all the issues surrounding FTDI chips and drivers, I decided I’d look at a competing chip – the Microchip MCP2221.  Unlike the “standard” FTDI FT232 (which is most similar to the MCP2200), the MCP2221 includes both a UART and an I2C interface. Hookup…

I logged in to this blog today with the intent to post something.  I have five drafts started, but none of them are finished. And I somehow doubt that I’ll finish any of them soon. Lots of stuff going on: I bottled my first lager a few weeks ago I LOVE…

Happy New Years! Everyone does some sort of sappy new year’s day post with some resolutions that they forget a few weeks later. I’m going to be different – unlike last year where I actually had some resolutions, this year I have some things in progress.…

I'm a new homebrewer and went in there for hops that I couldn't find at Jungle Jim's. After seeing how much grain (and they mill it for free!), hops, and real yeast AND after how helpful they are at making sure I got what I needed, I'm going here FIRST for brewing ingredients from here on out.

The pizza was great, and the service was excellent. Went there with 3 kids just before prime dinner time on a Saturday. The waitress did an excellent job of making sure she put stuff out of our little kids' reach (especially their food, which came out earlier than my wife's and my pizza and was hot). The restaurant also has a great beer selection- although I didn't see any local beers, there was a lot more than Bud/BL/Miller/ML, and I felt like some other beers (such as the Long Hammer IPA) were more prominently displayed in the beer menu.

Wait staff is useless. The place is not very clean. The Frisch's across the street is actually better (and they suck too, just not as bad).

The coffee is EXCELLENT. Comparing it to Starbucks, it is a little less expensive but tastes like it should cost twice as much. The employee (presumably the owner) was very personable and talkative, and the other customers were really nice too (I know you can't really review on that, but something must've made them happy).

Place needs a lot of work. Got to room to find that the A/C had been off, so it was like an oven in the room for a while. Two microwaves in the room, one OLD TV. The only good thing is that we (by the grace of God) managed to not end up with bedbugs, roaches, or other hitchhikers. It was cheap, however.

Nothing like having a big field with NO TREES in the middle of a campus in Florida.

MUCH better selection and prices than Radio Shack. Not the prettiest store, but the guy behind the counter won't give you a blank stare if you ask him for a 22uF 50V capacitor (and he won't try to sell you a cell phone either!).
