How to Make a Pop Screen For Podcasting

For the past six months, I have been co-hosting a weekly podcast called The Tightwad Teacher. In addition to getting the opportunity to speak with all kinds of cool folks from around the globe, the experience has given me a chance to reflect on my own speaking skills. After each show is published, I listen back and grimace over every "um," "ah," and other lapses in good diction.

I also focus on the audio quality of the recording. Much of this is out of my hands as the sound is only as good as that particular Skype connection, but I recently became aware of the dreaded popping P and hissing S sounds that seem to plague some recordings. Keeping with the tightwad ethos of the podcast as well as some of my recent posts (like this one and this one), I decided to see if I can make a pop screen to remedy this recording problem.

Below is my easy tutorial for making a pop screen with junk you may have laying around your house.

Materials:

• Plastic coffee can (I used Folgers, but any will do)
• 1 Pair of women's nylon stockings (I bought a pair at the Dollar Store, but an old ripped pair will work just as well)
• A few rubber bands
• 1 magnetic clip
• 1 stand (I used an extra microphone stand, but you can get creative and use whatever you have that can serve as a base)

Step 1: Using a knife or sharp pair of sheers, cut the lip off the plastic coffee can. This will serve as the frame for the pop screen.


Step 2: Cut both legs off of the stockings. Slide the coffee can frame into the stockings and then twist both ends to make the nylon taught over the frame. Rubber band each end and then trim any remaining nylon.


Step 3: Attach the magnetic clip to your newly assembled pop screen. My base was metal, so the magnet held it firmly in place without much need for adjustment.


Alternative construction: If you do not have a magnetic clip or microphone stand handy, you can easily fasten the pop screen to a box using a few safety pins pushed through the nylon and into the cardboard. It won't look as pretty as mine, but it'll do the trick!

Once your pop screen is fully assembled, simply place it between you and your microphone. I've tested mine out, and there is a noticeable reduction in pops and hisses - I can't wait to try it out during my next podcast interview!

How to Make an iPad Stylus for Under a Dollar

I recently discovered the joys of making Flipped Classroom-styled videos using my iPad and the free whiteboard narration tool called Show Me. When the iPad is connected to a projector (as I described in this earlier post), I find Show Me to be a great way to simultaneously provide notes to my class while also creating video review materials that can then be posted on the class website or blog.

There's just one problem - I quickly learned that producing legible handwriting with the end of my index finger is much trickier than expected. I did a quick search online and found that iPad styluses averaged about 20 dollars. Rather than blow the cash, I decided to make my own.

What you'll need:

• A pen, highlighter, or marker (I used a highlighter that had recently dried up)
• A sponge
• A piece of wire (about 6 inches should suffice)

How To:

1. Disassemble the writing utensil. You can throw out the insides - you only need the casing.

2. Cut a strip of sponge off the pad (if your sponge was like mine, make sure to remove the green scrubby surface first!).

3. Expose some of the bare wire and twist it around the sponge.


4. Guide the wire through the end of the casing and then gently twist the sponge up and into the shaft. If it's not snug, cut a larger strip of sponge and try it again. Make sure you leave a bit of sponge protruding from the end of the casing for use as a contact point with the iPad!

5. Remove the coating from the remaining bit of wire and wrap it around the exterior of the casing. Your fingers must be in contact with this as you write for the iPad surface to respond to the sponge tip.


For some reason step five proved to be unnecessary for my stylus to function properly. Either because the iPad was so sensitive or because the plastic casing somehow served as an adequate conductor, I didn't need the wire, so I removed it. Here is my finished gadget. Pretty cool, huh?

How to Register Multiple Users to One Email Address

Here’s a familiar problem that teachers often run into when trying to use web 2.0 sites or services with students. Creating a user name and account may be fast and free, but most times also requires a unique email address. If you teach at a school where students are not given their own address, this suddenly gets much more complicated. Students can use their own personal email to register, but then you as the teacher do not have access to passwords in the event that someone forgets. Also, if your district filters email sites such as gmail, yahoo, or AOL, then students may not be able to retrieve lost information or even activate the account at all.

This one small hang up has prevented me from using sites such as Blogger, Weebly, Xtranormal, Aviary, and SlideRocket (to name just a few) with my students. Until now, that is.

This method takes advantage of a little-known but extremely useful Gmail hack. Gmail has a recipient sorting feature where a “+” can be added to an address to identify the intended target.

For example: Let’s say my wife and I use the fictional email address MikulskiFamily@gmail.com. If you wanted to send a message and wanted to make sure it was clear that it was intended for me and not my wife, you could actually send it to MikulskiFamily+JOHN@gmail.com. This would still go to the same inbox, but I would see that it is specifically for me.

In three easy steps, you can create unlimited user accounts to any site with just one email address.

Step 1: Create a Gmail account
Gmail is blocked at many schools, so this will have to be done from home. Create an account specifically for your classes. If you are already a Gmail user, don’t use your personal email address.

Step 2: Forward mail
Under the settings menu, change the forwarding option to redirect all mail to your primary work address. This is very important for two reasons. First, you want to have access to activation/password emails in the classroom, but also so that all email is stored on the school email servers. You don’t want to find yourself in a tricky spot where an administrator is accusing you of handing out a personal email address to students.

Step 3: Assign “unique” addresses
When students sign up for whatever service you choose to use, assign them a number. Have them add this number to the email address (Teacher+1@gmail.com, Teacher+2@gmail.com, etc.). The website/service will identify it as a unique email address, but all mail will be redirected to your work email!
