Advice needed on flame powered THERMOELECTRIC FAN project

Leave a comment

By arbee

I am organizing a parts list to build a peltier fan, using a TEC module to generate DC current using a small alcohol lamp as the heat source, a DC motor to swing an 8 – 12 inch fan blade, & 2 heat sinks to heat & cool the TEC. My problem: The only “how to” article I can find details use of a TEC1-07110T200, which is no longer available @ a reasonable price. The only high temp. (200 deg.C) TEC available for less than $20 is a TEC1-12706T200, which has different electrical parameters: (VMax = 15.2v/IMax = 6A/QMax = 51.4w/Tmax = 200 deg.C) I intend to use the recommended Mabuchi RF500TB motor (rated @ 1.5 – 6 vdc) which is used w/solar cells, & runs @ low amperage w/relatively high torque @ low RPM’s. QUESTION: Is this Mabuchi motor a good match for the new TEC, or should I get a different motor? If so, please give details/specs of motor needed. The original builder (using the old TEC) measured a current of approx. 0.5 vdc at a very low amperage. Heat conversion to electricity is stated to be very low @ approx. 0.02%, so getting a motor designed to maximize the available electrical input is essential. His video shows his fan spinning rapidly enough to creat the desired breeze. Any assistance appreciated.

Review: Peazip 5 decompresses everything

Leave a comment

Peazip is one of the most versatile file compression and archiving utilities out there—possibly the most versatile—and it’s free. It’s also quite easy to use and offers the same features found in programs such as WinZip and WinRAR such as context menu integration, passwords, command line usage, etc.

Peazip supports every compressed archive format I’m aware of: 7Zip, ARC, GZ, TAR, ACE, RAR, etc. There’s also support for both ISO and UDF disc images and Linux package formats such as DEB, RPM, PET/PUP, and SLP. As a bonus, you can open Mac HFS DMG files. There are more, but the point is that there’s little out there in the way of compressed file you can’t browse and extract from.

As you can tell from the file type associations dialog, Peazip supports a lot of formats.

While I’ve always appreciated the effort that goes into this piece of free software, I’ve also installed, then uninstalled Peazip several times over the years because of operational and performance issues. This has left me using WinRAR, which while a bit old-school looking, is rock-solid and fast. Version 5 of Peazip seems quite a bit more stable, but it still has a tendency to not close and launch 100% smoothly when you’re dealing with multiple instances. Also, the progress bar is still inaccurate, claiming far less progress than as actually been made. Several times, it was only 25% across when the task completed.

Skype-Installer for Plasma Active

Leave a comment

Today i’ve finished my small Shellscript for installing Skype in Plasma Active. Its tested with the Plasma Active Mer Image (i686). But it should work in other architectures too.

What does the Script?

It downloads the latest Skype Version (dynamic package) and tries to find a already installed Version of Skype. To do that it searches in the RPM-Database and also in /usr/share/skype. Then it removes the old ones, and installs the new (the downloaded) version.

The script places the files on the same place like the RPM package does it. So it should be compatible.

While my tests i haven’t found any troublemakers. So please, if you find anything, just drop me a note: saigkill@open-slx.com.

So have fun with it 🙂

Aah.Forgotten to say where. Just type in your Plasma Active Device:

curl –output skype-installer http://saigkill.homelinux.net/pub/skype-installer

Then a chmod +x skype-installer and you can run it with ./skype-installer

If you like the script, you can anything 🙂

RPM International Earnings: An Early Look

Leave a comment

By Dan Caplinger, The Motley Fool

Filed under:

The new earnings season is about to begin, but a few companies on off-quarter fiscal years are just now getting around to reporting their quarterly results. RPM International is about to release its quarterly earnings report. The key to making smart investment decisions with stocks releasing their quarterly reports is to anticipate how they’ll do before they announce results, leaving you fully prepared to respond quickly to whatever inevitable surprises arise. That way, you’ll be less likely to make an uninformed knee-jerk reaction to news that turns out to be exactly the wrong move.

Companies that stand to benefit from a rising housing market have been increasingly popular lately, and RPM‘s extensive lineup of waterproofing and weatherproofing products for everything from driveways and wood decks to roofing sealants and caulk definitely qualifies it as a play on home ownership. Let’s take an early look at what’s been happening with RPM International over the past quarter and what we’re likely to see in its quarterly report on Thursday.

Will RPM International be loss-proof this quarter?
Analysts have gotten a little less optimistic about RPM‘s prospects in recent months, as they’ve reduced their earnings-per-share calls by a penny for the most recent quarter and by $0.03 for the full 2013 fiscal year. The stock has posted a modest advance of about 6% so far this year, but that’s well below the overall market‘s performance, let alone that of some high-flying housing-related stocks.

RPM has benefited greatly from better prospects in the housing industry. As results from the homebuilding sector have gotten stronger, demand for RPM’s sealants and coatings has followed suit, sending share price higher. In addition to providing consumer products like Rust-O-Leum and DAP, the company also provides a wide variety of materials for industrial companies and commercial builders. The industrial segment makes up two-thirds of RPM‘s overall business.

But RPM has plenty of competition to deal with. Both Sherwin-Williams and PPG Industries dwarf RPM in size, although both of those companies are much more focused on the paint sector, which has its own specific industry dynamics. Nevertheless, just as PPG and Sherwin-Williams have had to deal with the ups and downs of the titanium dioxide market — a key pigment for paint production — RPM also mentions it as a key driver of its raw-materials costs, in addition to certain resins and solvents related to other products.

In its quarterly report, watch for RPM to discuss why its revenue growth has lagged behind that of PPG and Sherwin-Williams over the past year. Without a satisfactory explanation, it’ll be hard to justify paying 25 times trailing earnings for the stock, even with a …read more

Andrea Veri: Setting up your SSL certificates on OpenLDAP by using a Mozilla NSS database

Leave a comment

I’ve recently spent some time setting up TLS/SSL encryption (SSSD won’t send a password in clear text when an user will try to authenticate against your LDAP server) on an OpenLDAP istance and as you may know the only way for doing that on a RHEL / CentOS environment is dealing with a Mozilla NSS database (which is, in fact, a SQLite database). I’ve been reading all the man pages of the relevant tools available to manipulate Mozilla NSS databases and I thought I would have shared the whole procedure and commands I used to achieve my goal. Even if you aren’t running an RPM based system you can opt to use a Mozilla NSS database to store your certificates as your preferred setup.

On the LDAP (SLAPD) server

Re-create *.db files

mkdir /etc/openldap/certs
modutil -create -dbdir /etc/openldap/certs

Setup a CA Certificate

certutil -d /etc/openldap/certs -A -n “My CA Certificate” -t TCu,Cu,Tuw -a -i /etc/openldap/cacerts/ca.pem
where ca.pem should be your CA’s certificate file.

Remove the password from the Database

modutil -dbdir /etc/openldap/certs -changepw ‘NSS Certificate DB’

Creates the .p12 file and imports it on the Database

openssl pkcs12 -inkey domain.org.key -in domain.org.crt -export -out domain.org.p12 -nodes -name ‘LDAP-Certificate’
pk12util -i domain.org.p12 -d /etc/openldap/certs

where domain.org.key and domain.org.crt are the names of the certificates you previously created at your CA’s website.

List all the certificates on the database and make sure all the informations are correct

certutil -d /etc/openldap/certs -L

Configure /etc/openldap/slapd.conf and make sure the TLSCACertificatePath points to your Mozilla NSS database

TLSCACertificateFile /etc/openldap/cacerts/ca.pem
TLSCACertificatePath /etc/openldap/certs/
TLSCertificateFile LDAP-Certificate

Additional commands

Modify the trust flags if necessary

certutil -d /etc/openldap/certs -M -n “My CA Certificate” -t “TCu,Cu,Tuw”

Delete a certificate from the database

certutil -d /etc/openldap/certs -D -n “My LDAP Certificate”

On the clients (nslcd uses ldap.conf while sssd uses /etc/sssd/sssd.conf)

On /etc/openldap/ldap.conf

BASE dc=domain,dc=org
URI ldaps://ldap.domain.org

TLS_CACERTDIR /etc/openldap/certs
TLS_REQCERT allow

On /etc/sssd/sssd.conf

ldap_tls_reqcert = allow
ldap_uri = ldaps://ldap.domain.org

How to test the whole setup

ldapsearch -x -b 'dc=domain,dc=org' -D "cn=Manager,dc=domain,dc=org" '(objectclass=*)' -H ldaps://ldap.domain.org -W -v

Troubleshooting

If anything goes wrong you can run SLAPD with the following args for its debug mode:

/usr/sbin/slapd -d 256 -f /etc/openldap/slapd.conf -h “ldaps:/// ldap:///”

The Death of a Multibillion-Dollar Tech Industry?

Leave a comment

By Eric Bleeker, CFA, The Motley Fool

Filed under:

In the following video, senior technology analyst Eric Bleeker looks at one of the most struggling areas in technology: mobile advertising. 

Three years ago, as mobile was exploding, everyone wanted a piece of the market. After all, soon everyone would soon have a smartphone in his pocket, how could this not be the next tech gold rush? Google  bought AdMob and Apple  bought Quattro and created its iAd agency. 

Yet enthusiasm for mobile advertising has waned. Two companies that specialize in the field, Velti  and Millennial Media , are two of the worst performing stocks across the past year. Overall, smartphone advertising rates stand at an RPM — the price paid per thousand page impressions — of $1.31, according to eMarketer, which is well below the $4.70 average on desktops. Apple quickly moved the minimum price for iAd campaigns from $1 million down to $100,000. 

Eric notes that all hope isn’t lost. While mobile advertising in apps and banner ads might be in trouble, mobile search advertising could be in comparable good shape. Google recently launched its Enhanced Campaigns program, which will spur more adoption of mobile search advertising. 

Yet, in the end, Eric notes that the rise and fall of mobile ad companies is a warning sign. Trends in technology are difficult to predict. A can’t-miss technology like mobile and smartphones sparks as many losing ideas around it as it does winning ones. 

To see his full thoughts, watch the video.

After its recent sell-off, is there reason to sell Apple, or is this an opportunity to be greedy and buy more when others are fearful? The Motley Fool’s new research report on the company gives you the right information so you can make a decision whether Apple has a place in your portfolio. Best of all, it comes with continuing updates and exclusive reports. To get started, just click here now.

<<< Question related to making of RPM package >>>

Leave a comment

By kamauv234

Hi all,
Pls provide your suggestions and advice for the below queries. I have a files like below sample

$ ls -l /u01/app

-rw-r--r-- 1 appusr appdba 4 Feb 20 21:35 test
-rw-r--r-- 1 appusr appdba 4 Feb 20 21:35 test1
-rw-r--r-- 1 appusr appdba 4 Feb 20 21:35 test

– I want to make it as a rpm package for all the files under this folder (/u01/app)
– Make it as a relocatable package (it can be install in different directory)
– Sometimes appusr (user) group can be different in some of the servers (not appdba). So that time it will get the appusr group and change the permission accordingly

Pls share the spec file and provide your suggestions. Thanks !

Regards
Kannan
