Vintage Terrwave Battery With A Bad Fuse

If you find yourself surveying with a very old version of this Terrawave battery pack and it is suddenly not charging, or only works when it is connected to the wall charger, the fuse in it may have gone bad.

Remove the main unit cover, and you will see a plastic housing with a glass fuse in it.  The glass fuse was broken, so I replaced it with a fuse I purchased from RadioShack (4/$2.00).  After replacing the fuse, the battery took a charge, and worked properly after obtaining a full charge overnight.

The symptoms I had were that the battery did not take a charge from the wall wart, and the wall wart did not show that there was a load on it.  The light stayed green - indicating the battery pack was not charging.

The battery pack would not power on an attached access point unless the battery pack was connected to wall power.

White Spaces - new wireless space launched

Remember the death of analog TV? Those unused analog TV channels are now approved for use as wireless White Spaces. White spaces operate at lower frequencies, and are able to travel great distances just as analog TV signals did when they were in use. Supporters of white spaces say that use of these regions of  licensed spectrum offer the same benefits of WiFi spectrum with the added advantages of the signals traveling greater distances, and the ability to assign spectrum to avoid wireless interference.


Spectrum Bridge has been been given the green light to become the database administrator for all allocated white spaces.

KTS Wireless is the first manufacturer of a wireless device to take advantage of the white spaces spectrum re-allocation for wireless communications. They have participated in city wide trials of white space usage in Claudeville, VA and Wilmington, NC.






It will be interesting to see how usage of the white space advances. Currently, the FCC is working through how to address the issues of wireless microphones using the same frequencies as white spaces. Once those issues are resolved, the nationwide roll out of white space usage will be possible.

Technology crops up in the strangest places

Recently I've come across a lot of great out of print or public domain Film Noir movies shared on YouTube. Being able to watch these films is great in itself, but I really love it when technology figures into a critical character development or plot twist in a new way than in any of the other films I've seen.

The plot of 711 Ocean Drive (1950) had a considerable amount of technology featured in it, and many of the scenarios are still relevant today even though our technology has improved vastly since 1950. The main character Mal Granger works for the phone company, and he's a pretty smart cookie.

He sets up an analog multicast delivery system to improve the efficiency of the bookie's business transactions:

He rigs up a contraption to use a chain link fence as an aerial antenna to transmit racing scores:

He gets a big idea to hold the network hostage so he can get a bigger cut of the bookie's business:

(sound familiar?)

Finally he stages a Man-in-the-middle attack on a horse race in order to win big:

One other great bit of technology cropped up in The Mob (1951). The police rigged up a contraption to fit under the wheel well of the suspect's car. The contraption produced drops a liquid that glowed when exposed to ultraviolet light at regular intervals onto the rear tire of the car. In order for the cops to find the suspect's car, they just had to shine a UV spotlight on the ground and follow the dotted line.

Using Adobe Acrobat to Find the Square Footage of a Floor Plan

I made this recording back in 2009 to show how you could use Adobe Acrobat Pro to scale a floor plan, and ultimately find the square footage of a given area.

More often than not, I'm faced with figuring out the square footage of a building layout with no scale indicated on the drawing. Adobe Acrobat Pro has a measuring tool built into the application. You can take any image file, find the scale ratio of the drawing, set the scale, then calculate the square footage of the floor area.

The measurement tool line in newer versions of Adobe Acrobat Pro is a red line, instead of black, and it is easier to see the perimeter area you're drawing. Other than that, the video should help you get more out of an application you already have, but maybe weren't using for this task.

Wireless Field Day II

I'm very excited to inform you (if you haven't already heard) of the second Wireless Field Day that'll be taking place in San Jose on January 25th - 27th 2012. Assuming that the Mayans are wrong, we will be gathering in San Jose to hear presentation from a great group of wireless companies.

The majority of my career I've been focused on Cisco's wireless hardware line, so I'm looking forward to hearing about the wireless solutions offered by Aruba, Meraki, Ruckus and refreshing my knowledge of AeroHive. I've used troubleshooting tools by MetaGeek and Ekahau, but I'm sure I'll still learn lots from their presentations.

The final list of delegates are: Daniel Cybulskie, Sam Clements, Rocky Gregory, Andrew vonNagy, Chris Lyttle, me, Tom Hollingsworth, Matthew Norwood, Blake Krone, Marcus Burton, George Stefanik and Jeremy Gaddis!

Since the last Wireless Field Day I've gone pro on Flickr & Vimeo, so there's no limits to how much digital content I can record and upload. Consider this fair warning.

Configuring a 3500 series Access Point as an OfficeExtend Access Point

There are a couple of great how-to guides for configuring Office Extend APs on the web. Once upon a time, documentation for the OfficeExtend feature was a rarity. Back then the only guidance was from this great post from Blake: Cisco OfficeExtend AP600. Now we have the config guide from Cisco: Aironet 600 Series OfficeExtend Access Point Configuration Guide

I used Blake's post about OfficeExtend when I setting up my first OfficeExtend access points, since the configuration guide from Cisco didn't exist at the time. Today, I made a quick little video showing how and where the configuration changes are made. I also included how to see what your AP has configured for the controller name and IP address it is going to look for when the AP is powered on.

Sniffapalooza Barcelona 2011

Recently I spent a week in Barcelona at a Sniffapalooza event. What’s a Sniffapalooza event you ask? Sniffapalooza is a scent focused event for the fragrance enthusiast. This means the two main ladies behind Sniffapalooza are Karen Adams and Karen Dubin arranged for the group to visit with several perfumiers in Barcelona, talk about their creations and experience a slew of other fabulous fragrances while we were there. We also visited TablaoCordobés and saw a Flamenco show, Park Güell, La Sagrada Familia, the Dali Museum and San Pedro Church in Figueres, Girona Cathedral in Girona, Montserrat, and some of us took a tour of Gaudi’s La Pedrera. This Sniffapalooza trip to Barcelona had 18 attendees, which according to Karen D. was one of the smaller Sniffapalooza events.

The first day on the ground in Barcelona was cold and rainy. The wet streets just added to the atmosphere of the city. I wandered around and shot a pack of NOS Polaroid film instead of going to sleep. 


Each of us received a wonderful gift bag of goodies from Jordi Cabezas from JC Apotecari. My bag had samples of Carner Barcelona’s Tardes, Cuirs and D600, samples from Sepai and a agua de colonia fresca from Hierbas de Ibizia!




Our hotel for the week was the Hotel Colon. The Hotel Colon was constructed in 1951, and is well placed in front of the Cathedral of the city, just a few steps away from Las Ramblas and the Port of Barcelona. All this being said; the wireless connectivity in the hotel was useless so I picked up a Vodafone k3806 USB stick so I could upload photos from the trip each day. I was glad for the good weather in Barcelona that week, I didn’t need the heat/air to work in the hotel room (it didn’t anyway).

For our first evening in town, the group was bussed over to TablaoCordobés in Las Ramblas for a surprisingly good buffet dinner and Flamenco show. We probably could have walked, since it wasn’t that far – but it was nice to kick back and be driven around. The Flamenco show smacked heavily of ‘tourist attraction’, but the singers and dancers seemed to be enjoying themselves, and this helped neutralize the ‘tourist attraction’ feel I had at first.

For day two, we all piled into the bus for the twenty minute drive out to Park Guell, followed by a tour of La Sagrada Familia. Everything our tour guide Ines told the group about Gaudi, Park Guell and La Sagrada Familia was news to me, and I enjoyed her explanations and historical anecdotes. I resisted my natural urge to research every angle of the trip and what we’d be seeing while we were there, and instead let the events and experiences unfurl at a natural pace.


Our guide Ines had a great personality, and I loved listening to her accent while she explained the history of Park Guell and La Sagrada Familia. I shot a couple of videos of her and put them up on YouTube:

Later that afternoon we took taxis over to JC Apotecario in the Sarria neighborhood of Barcelona. The proprietor of JC Apotecario, Jordi Cabezas took us on a walking tour of his neighborhood (Sarria) before we began the presentations by Sara Carner, Paola Gugliotti for Sepai and Deborah presenting Hierbas de Ibiza at JC Apotecario. 


Sara Carner told us about her perfume line ‘CARNER BARCELONA’ and the imagery and emotions behind each perfume in her line (TARDES, CUIRS, D600). 





Jordi treated us all to a wonderful tapas dinner at El Villano (upstairs) at El Canala. The food kept coming, the wine kept flowing, and everyone had a great time.






The bus ride on day three to Figueres to see the Dali museum was just over an hour and a half. It was interesting to take a highway tour of the areas between Barcelona and Figureres. The cemetery just off the highway in Barcelona looked really interesting, and I wished that had been part of our tour. Unfortunately, it wasn’t within walking distance of our hotel either. 


While Ines readied our admission tickets to the Dali museum, some of us ducked into the San Pedro Church just outside the museum entrance. Inside were some of the most pained religious statues I’ve ever seen. It was both very creepy and very cool at the same time. I wish that the lighting on a few of the statues hadn’t been quite so harsh, it detracted from the emotions shown on the statues faces.

The Dali museum was great (naturally) and I was surprised to discover a theme in Dali’s later works that I did not know about. Dali had incorporated elements of computer technology into his later paintings and sculptures, and I liked seeing his use of circuit boards in creating a Japanese warrior statue, and art nouveau designs inspired by circuit board traces in his later paintings.


The craziest, coolest thing at the Dali museum had to be the beating heart brooch Dali designed. It was on display with all of Dali's other jewelry creations.

On the ride back from Figureres, we toured the city of Girona and the Girona Cathedral. Sadly to report, no photography was allowed inside the Girona Cathedral, but there are a few pictures of the cathedral online. We took a foot tour of the winding city streets of Girona led by Ines. She told us the history of Girona architecture and reminded us that the same streets were also used as settings for the filming of ‘Perfume: The Story of a Murderer’.


Later a group of us went out walking in the city, and we happened to be at El Corte Ingles at closing time. They get the message across that the store is closed by counting out the cash drawers very loudly.

Day four was a quick forty-five minute trip to Montserrat to see The Black Virgin of Montserrat. There were no restrictions on photography inside the basilica and it was replete with colors, texture, sounds – too many experiences to record even though I tried.

After the tour of Montserrat, some of us regrouped and walked over to La Pedrera and took a tour of Gaudi’s building and one of the apartments inside the building. I think the rooftop would have been better without all the metal ‘don’t fall over the edge’ railings, but the apartment was very interesting because of all of the period furniture and belongings that the original apartment owners would have had. The best rooms were the bathroom and the children’s room.

On the afternoon of the fourth day of Sniffapalooza, Lisa from The Perfumed Court and I walked over to check out the Santa Maria del Mar Cathedral in the Ribera district. Cathedrals start to look the same inside when you've toured one after another for a couple of days straight. When I looked down at my feet, it was a completely different story. The entire floor of the cathedral was a burial ground, and each of the tomb tops were engraved with dates or figures. 1699 was the earliest date I could find.


The only event I did not attend was at Amorino Gelato where the group's host Claudia Guinot gave everyone a private tour of the Gelato shop, and everyone was treated to samples of the gelato.

The morning of our fifth day of Sniffapalooza found us gathered in a meeting room of the Hotel Colon for a special presentation of the creation of ‘Lemon Cloud’ by Agusti Vidal and Pastry Chef Jordi Roca (of El Celler de Can Roca). Their original idea was not to create a perfume for sale, but as a side element to their pastry creations. Lemon Cloud was their first original scent. 

This is their presentation to the Sniffapalooza group, and I also found a YouTube video of Chef Jordi describing their creation 'Lemon Cloud'.

After Agusti and Jordi’s presentation, we all walked over to Regia to visit the Museu Del Perfum. The owner, Francesc Planas gave us a full tour of everything he's collected over the years. It is a wonderfully massive collection of vintage and ancient perfume bottles and accoutrements.





The key piece in my opinion was the flask that Marie Antoinette carried her perfume in when she traveled. I say this after reading 'The Emperor of Scent' and recalling the passage citing her perfume as the reason Marie Antoinette was captured while attempting to escape and ultimately, beheaded.

For our sixth day of Sniffapalooza we visited Puig, Firmenich, Cosmeticoh! and Santa Eulalia. Our guide for the day was the lovely and charming Nouriel. I'm fairly certain she'd never been a tour guide for a tour group such as ours. She seemed to enjoy herself during this day's sniffing events (with a little encouragement to go ahead and take part!)

Puig is the number 5 perfume house internationally. They have different operational segments within the company, and the one we were learning about that day works with celebrities to craft fragrances for the mass market.

Puig gave everyone a 2GB storage bracelet containing all the presentation information for all the fragrances shown that day.


 The best thing I smelled that at Puig was the perfume Diavolo. It was launched in 1997 by Puig and Antonio Banderas. It isn't available commercially to the US Market, but you can still buy it on Amazon.



Unfortunately, I don't have the names of the ladies that spoke to us that morning, but hopefully I will be able to include this information later.

Firmenich is a private Swiss company in the perfume and flavor business, it is the largest privately-owned company in the perfume and flavor business, and ranks number two worldwide. They producing perfumes for Carolina Herrera, Comme Des Garcon, Paco Rabanne, Gaultier and Prada to name a few.



The ladies at Firmenich provided us with a light tapas lunch. It was very nice of them to provide refreshments and snacks for all of us. There were all kinds of tapas laid out in their kitchen, sodas and coffee were also provided.




 Paola Zanni and Ina Mexia presented us with the Firmenich scentorial experience. It is a showcase of their perfumers’ creations when they are given carte blanche to make whatever scents they are inspired to create, based on four different concepts presented to them by Firmenich.

We toured the new Cosmeticoh! Shop with the owner Oriol Blanch and learned about the new Oliver & Co. perfume and candle line from the creator himself - Oliver Valverde. This was his first English speaking presentation and he was very nervous. I think he did wonderfully!

I fell in love with M.O.U.S.S.E and Dunard, and bought a bottle of each! Oliver uses the tried but true tactic to get you to buy a bottle of what you like *now*, because each perfume is created in limited, numbered runs and once the supply is exhausted, that’s *it*.

Our last stop of the day was at Santa Eulalia. The store was built in 1843 and offers a selection of luxury brands for men and women in addition to a tailoring service. We toured the perfume counter and sampled fragrances by Maitre Parfumeur et Gantier, Grossmith’s Hasu-no-Hana, Byredo Parfums, Nasomatto, and Eight and Bob by Albert Fouquet. 

Mar Jordan of the perfume department at Santa Eulalia gave us a specialized tour of the perfumes they carry.

The scents that appealed to me most were APOM Pour Femme by Maison Francis Kurkdjian and Gypsy Water by Byredo Parfums.

The hidden secret of the Santa Eulalia department store is where you’d expect to find a hidden secret - in the basement! Our tour of the store concluded in the men's department downstairs. We were shown the area of the shop where the tailoring magic happens. 







They had displays for the bespoke styles of shirt collars, cuffs, suiting fabrics and the pattern pieces they've used for generations were all neatly labeled and hanging in the tailoring room.

Barcelona was great, I met a lot of great people, saw a lot of interesting things, but the most marked difference between the states and Barcelona was the shoes!
