2007 Flowers (Plants)

Rosemary
(Click for more photos of the 2007 Flowers around my house (photo gallery retired)…)

Arriving home a bit early from training at the Microsoft facility in Southfield I decided to head over to Deneweth’s Greenhouses, which is just down 22 Mile Road from my house, and grab some flowers.

Well, instead of following the trend from previous years and planting just flowers I decided to pick up some pretty herbs and chilis as well. The four things planted are Rosemary (Rosmarinus officinalis – as seen above), Caribbean Red Habernaro, Obsession with Blue Eye Verbena, and Victoria Blue Salvia Farinacea. I’m quite happy with how they all look spaced out around my front porch and such. With the salvia growing to 12″ – 20″ it should be nicely, imposingly friendly. Hopefully the chilis will be good, and the rosemary gets as bushy as I’d like. Ideally I could regularly bake bread using the rosemary. Mmm!

x0xb0x

It seems that I’m now able to order another x0xb0x kit. So, I shall. This one is more of an investment, though… Something easy / fun to build which I can slap my remaining piece of custom artwork on and sell on eBay. Or something. :)

It’ll be about $360 total, but I think it’ll be worth it…

HMLiberator v1.0 PCBs Ordered

HMLiberator PCB v1.0HMLiberator PCB v1.0
(Click for 600dpi version.)

Well, it’s done. I’ve ordered the first run of PCBs for the HMLiberator. While they are technically a prototype, these v1.0 PCBs should be also be usable as the final part. The circuit is pretty simple, and I’ve checked things over a number of times, and it all seems right. Now I just need to finish the software.

Thanks to Advanced Circuit’s $500 Free Promotion I was able to get a $500 credit towards one or two orders, making this entire order free. I’ve heard excellent things about Advanced Circuits, and due to the small tolerances on these boards I wanted to be sure they’d be done right. Also, should I go production on this item, 250 boards will only cost $1.94 each.

For now I ordered 12 boards, as any quantity from 5 to 12 were the same total price (price per board * quantity). With any luck I’ll have them by the weekend, or maybe early next week. Until then I can just finish polishing the software.

If you are interested, the schematic is available in black and white or color. I’ve also uploaded another file containing the Gerbers and CADsoft EAGLE files, should anyone be interested in them.

Now, to get back to normal work, and possibly update the online documentation for the project a bit later. I also should make a post about Saturday, which was a really nice day of beer brewing, friends, and beer in the evening. (Although I think a bit too much beer… or maybe too much Mt. Gay afterwards at ‘s place.)

OPPO DV-970HD

OPPO DV-970HD Upconverting HDMI DVD (and more) Player

Yesterday while and were over here for birthday things, the FedEx driver left my new DVD player in the garage so quietly I didn’t even hear the truck drive up. Because of yesterday’s activities I put off unboxing and setting up the player until today.

Well, as part of setting it up I took a number of photos of the unboxing of the player, the inside of it, etc. While deciding if I wanted to purchase the player I couldn’t find any good photos of the player, the remote, things like that. Since I normally find photos like this useful, I decided to take some in hope that others would find them useful.

First, I found out that AV Science is selling the players for US$149, plus $10 for FedEx shipping. While the players are available with free shipping via Amazon, I didn’t want to wait the typical two weeks that it takes for free shipping items to arrive.

The player arrived in a brown cardboard box. The box looked like it had been dropped on the corner a few times, but opening the box showed enough packing material that this was not a concern at all. Inside the box was the instruction manuals, a box containing the cables and remote, and the OPPO DV-970HD player itself, in a black cloth bag similar to what iPods ship in. (Strangely, this bag has hook and loop fastener closures.)

The remote is nicely sized and contains all the needed buttons, and also glows in the dark. Somewhat unlike most other players I’ve come across, the OPPO HD-970HD comes with a rather nice HDMI cable. (I’m using this cable, because initial testing has shown that allowing the player to upscale DVDs to 1080i looks best on my TV.) There are also a couple of audio cables in the package, but I’m not using either of those. Thankfully the player as a TOSLINK connector on the back, so I’m able to use that, just as I was with my old Sony S550D. (Rear view of player.)

This player also plays SACD, and (due to stupid restrictions on SACD) outputs the audio to the on-board 5.1 connectors. I still have to make cables to go between that and my receiver, but it’ll be nifty to give some of the surround sound discs a listen. (The player will also downsample / downmix them to stereo for digital output.) DivX support seems pretty good, although the only files I’ve tried playing are test encodings as part of the DivX TestCD v2.0.

One rather nifty thing about this player is that it’ll play supported media from either flash drives or USB v1.1 mass storage devices via the front panel card reader / USB connector.

I currently only have one complaint about it, and that’s regarding the brightness of the LED display on the front panel of the player. To put it simply, it’s brighter than anything else near my TV. I might look into either changing the resistors to dim it or simply unplugging it, but I’m not sure yet.

That all said, and while I haven’t taken the time to calibrate everything against the TV (the whites seem a bit blown out, as some things were trailing on the screen while watching test discs) the image quality seems to be quite good thus far. DVDs look loads better than they did with either my old player or any of the low-cost ones I’d tried last week. Thus far, I’d definitely recommend getting this player, and with the really prompt shipping from AV Science I’d suggest getting it from them. Being a custom AV shop they don’t do online orders, but if you call them up they’ll do the order that way. (I think they aren’t normally a single-item online retailer, but they are selling these…)

If you’d like to see more pictures of the player and such, including inside of the player, here is my OPPO DV-970HD unpacking gallery (photo gallery retired). OPPO’s site with more info on the player is here, and a huge thread about it at the AVScience Forums is here.

Now, it’s time for Danielle and I to go get some Thai food and just relax.

(By the way, if you enter setup on this player and press 9210 on the remote, a screen indicating the current region is displayed. Pressing a new region code, such as 0 for all, will change the region code.)

Simcoak (Beer)

Boiling the wort.
(Click for more moblog photos…)

Here’s the beer today, which I’m going to call Simcoak. Well, I’ll call it that if it actually comes out…

Wyeast 1056 – American Ale (Yeast)

2 lbs. Carapils Vienna
2.2 lbs. Muntons Extra Light LME
4 lbs. Muntons Extra Light DME
3 oz. Simcoe Hops (13.4% Alpha Acid)

3 quarts of water at 165°F Strike temperature, aiming for mashing temperature of 152°F. Mash for one hour.

Sparge with 4 quarts of water at 180°F.

Boil for one hour.

Hops at 60 minutes, 30 minutes, and 5 minutes remaining in boil, one ounce per addition.

1 tsp. Irish Moss (seaweed) at 15 minutes remaining in boil.

2 1/2 tsp. Yeast Energizer and 5 tsp. Yeast Nutrient at start of boil.

Original Gravity (OG) of 1.060.

Put to ferment at 15:10 EDT.

Once the beer is in ‘secondary fermentation’ (aka aging) I’m planning on adding a quantity of toasted oak which has been soaked in George Dickle bourbon for a while. Hopefully this will make it nicely oak-y, to go along with the extreme hoppyness. Alcohol should be mild, maybe 6% or so. Maybe this will make a nice summer-time after dark beer…

SMT Parts

Crystal, PIC, and voltage regulator on a laser printout of the HMLiberator
(Click for full size image.)

The first batch of board-level parts for the HMLiberator came in today. It’s enough parts for three devices, with a few extra SMT parts thrown in just in case I drop them, sneeze, whatever.

That up above there is a laser printout of the latest board layout with the electronics filling a 37mm x 25mm area. I’m going to redo the pinout of the cables to make routing of traces more efficient, but that shouldn’t affect the other areas. Also, as you can see, the part footprints are good. So, barring any manufacturing problems, it should work out great.

I took some more macro photos (true macros) of other SMT parts received today, because I thought some people reading this might be interested to see them:

· Four size 1206 SMT .33μF 25V capacitors sitting on a dime. These are Mouser part 77-VJ12Y25V334K.
· One of the .33μF size 1206 capacitors sitting on the PCB printout.
· Surface mount parts in cut tape packaging.

Next Project: Nixie Clock

After talking with jerronimo for a while on IRC about it, I think I’ve got a good idea about what I’d like my next project (after the HMLiberator) to be: a Nixie clock.

I’m thinking that it’ll be:

· Controlled by a PIC.
· Time / date / etc stored in a battery-backed PCF8583 (or so).
· Four Nixie tubes.
· Time / date / whatever will be set via serial terminal. PCB will include FT232BM for easy USB connection and footprints for DB9 connector, MAX232, etc.
· Other things may be possible via serial, including displaying one’s own data. This makes the clock also an external Nixie display for computers or embedded devices.
· Colon (:) in between pairs of digits can be turned on and off.
· Again, all open-source hardware and software. Probably done in mikroBasic since I’m getting to know it fairly well.
· I’ll make a few kits available to friends at cost, likely without enclosure.
· Maybe a bootloader so new firmware can be dumped on via serial port instead of ICSP?
· Possibly a way to control color-variable LEDs for illuminating base and / or tubes.

So, yeah. That’s a ways out, but I think that’s what I’ll work on next. :)

Twitter

Also, since ceasing to use Twitter I have not missed it. At all. In fact, I forgot about its existence until I saw an article about it a few hours ago.

I’m glad it’s gone. It’s irritating.

UPDATE: Also, something else I don’t miss is Apple’s Safari. I switched to Firefox 2.something on my Mac a while ago, and it’s really quite nice. Even though the spell checker isn’t consistent with the rest of the OS, widgets look odd, and QuickTime doesn’t play well with it, it’s still a great improvement.

Kensington Expert Mouse

Kensington Expert Mouse at my desk.Kensington Expert Mouse on my desk at work.

Yesterday while at CompUSA to see if there were any interesting / good prices on items I wanted (as part of their 50% – 70% off everything going-out-of-business sale) I came across a Kensington Expert Mouse for US$50. I’ve been wanting to try one of these for a few years now, but it’s high $100 price put me off. Well, at that price I couldn’t pass it up, so I purchased one.

That said, I’m not sure I like it. I think it’s the tilted-back position it naturally rests in, and maybe a combination of the sensitivity I need to set it at in order to feel natural, but after an hour or so of use the back of my hand begins to ache.

Also, installation of its drivers appears to have somehow disabled the Alp touchpad driver for my laptop. Part of this driver compensates for unintended brushes of the touchpad, so they aren’t turned into inadvertent mouse clicks. The software also allows one to assign the buttons to send combinations of keyboard presses, but I can’t seem to make it send things like Windows-D (Show Desktop) on Windows XP, or any of the Dashboard or Expose keys on OS X.

Beyond the thing mentioned above (which may be resolvable with some repositioning, acceleration adjustment, and noodling with drivers / software, I’ve taken to it pretty quickly. It doesn’t seem to work so well when doing PCB CAD.

I think that after a few days of trying it I’ll decide if I’m going to keep it or not. As these regularly sell on eBay for prices around (if not higher than) what I paid for it, selling it will just be a hassle and a financial wash. No money lost, really.

Now, to try and fix the Alps driver problem. That’ll be a real big issue for me if I can’t get it working, as my hands regularly pass right over the touchpad whenever I’m typing.

UPDATE: Reinstalling the Alps driver and rebooting has restored it’s functionality. Judicious playing with the acceleration profiles for both slow and fast movement of the trackball has helped make it easier to position things. Now, to give it a day or so of use.

HMLiberator PCB First Draft


First Draft of the HMLiberator PCB

Having some time on conference calls this morning I went ahead and began laying out the first draft of the PCB for the HMLiberator. Well, there it is. It’s small. Really small. 54mm x 25mm, in fact, and I could probably cut it down to 50mm x 25mm if I feel like it.

A 300dpi version of the schematic is available here, if you’d like to see it.

I’ll let the design stew for a few more days while I work on the software (and other thing — especially laundry) and wait for the first order of parts (enough for three boards, $20 total) to come in. After validating that the parts match their footprints, and assuming I don’t run into any huge problems with the software, I’ll order a prototype run of boards.

Oh, I also ordered one of the OPPO DV-970HD DVD players from AV Science as well. It was US$149 with $10 shipping. I wasn’t expecting to pay the shipping, but at least I know it’ll go out today, a small company is getting the business, and the forums they run helped me learn about and decide on the player and TV.
