So last month, I found out my friend's birthday was coming up, and I decided I had to get them something amazing.  She's a really big Doctor Who fan, and I had just finished watching all of the episodes currently on Netflix.  I was browsing around online looking for Doctor Who related presents, and I saw a few homemade sonic screwdrivers with cool features built in.  I don't have the skills to fabricate an accurate looking sonic screwdriver myself, but I do have some pretty nice soldering skills.  I knew what I needed to do.  I was going to make a Sonic Screwdriver, that could turn off TV's.  


Stuff for the Make to Learn Youth Contest:

What did you make?
I made a sonic screwdriver TV-B-Gone combo as a birthday present for a friend.  It started out as a crazy idea that I had one day, but transformed into the awesome finished product you see above.  In preparation for this, I learned all about how the TV-B-Gone circuit worked so I could modify it to use the least amount of parts possible.  In order to build it, I ordered parts off of Digikey, Amazon and Sparkfun, then I assembled everything according to my plans.  I used my Raspberry Pi, a breadboard, my trusty soldering iron, wire cutters, needle nose pliers, an exacto knife, solder, and desoldering wick.

How did you make it?
The idea came to me one day while I was browsing around online, I was looking for potential ideas for a birthday present, and I came across several homemade Sonic Screwdrivers online, and thought, "Hey!  I can do something like that!"  and it worked out perfectly because my friend is a huge Doctor Who fan.  I ended up using my dad's help to split it open and his clamps and plastic cement to seal it back up.  My initial design called for a capacitor to help smooth out the current, but in the end it ended up not fitting, so I had to leave it out.  I could probably have left out the resonator too, but I had already bought it, so there was no point in wasting it if it fit.  

Where did you make it?
I made this at home, upstairs in the room with all of my dad's model trains.  He has a small work area up there that I'm allowed to solder at, and it's got this really comfortable chair to sit in, which definitely helps with my ADHD.  I had to balance this with homework because the last day of the term was today, and I had to make sure I had all my grades in order.

What did you learn?
Honestly, this turned out amazing!  I only had two gripes, and those were the range and the fact that I had to leave out the capacitor.  It functions just fine, but you can see the UV LED flicker ever so slightly when in use.  I feel the most proud about programming the microcontroller, it was a first., that combined with this being my first complex circuit made me really happy.  All in all, it was a project full of firsts for me, and considering I designed the whole thing myself, and it actually works, made me a really happy person the last week or two.  It doesn't hurt that my friend loves it either!

Step 1: Designing

Once the idea came to me, I had to design the blasted thing.  I started initially by researching the schematics for the TV-B-Gone.  I knew this was what I needed to use, but there was no way I could fit all of that inside any Sonic Screwdriver.  Meanwhile, I started looking at various Sonic Screwdrivers available online, and at first, I wanted to use this, but not only was it too small, but it didn't make noise, and had multiple inaccuracies from the one on the show.  Ultimately, I settled for this instead, a bit pricier, but altogether worth the extra money.  The added price meant that I had to bring in extra friends, and luckily they were willing to chip in as long as they got credit too.  With the Sonic Screwdriver picked out, I had to get back to designing the circuit that would flash the codes.  Mine is heavily based off of Ladyada's TV-B-Gone, but with fewer parts in order to fit inside of the Screwdriver.  After a quite lengthy conversation with JeonLab, I concluded that the only parts that I had to order were a microcontroller, a resonator, an LED, a transistor, and two resistors.  I also ordered a capacitor as you will see in the pictures I took, but ultimately left it out due to size restrictions.  Another help was Panik, from the Raspberry Pi forums.  As you can see here, he helped me learn how to program an Attiny with my Pi.  Once I had the parts figured out, I drew up a set of schematics shown above using SchemeIt, a free online schematics designer provided by Digikey.
<p>I just finished my own.</p><p>I used an arduino as my ISP, which worked out very well!</p><p>My sonic didn't fit together perfectly, but all in all I would say it was a success. </p><p>Here are some images!</p>
<p>Nice job!</p>
<p>I also made one!</p><p>It took quite a while to solder all the individual tiny components but it actually works!</p><p>It takes up to what seems like a minute to turn on/off my telly.</p><p>I had been trying to make this for over a year using Matt Smith's screwdriver but couldn't get things to fit in correctly.</p>
<p>email me at <a href="mailto:casperdj777@yahoo.com" rel="nofollow">casperdj777@yahoo.com</a> &amp; let me know how much to buy one or two</p>
<p>Sorry for being such a noob but I was wondering if you could explain a little more about how the circuit works. I am kind of new to this and don't really know how to read schematics. One more thing. I have a preprogrammed chip from adfruit. Will this work instead of programming a new chip? Also, is it powered by the 3 1154 batteries or some other power source? Thanks for the help!</p>
<p>I want one </p>
<p>please contact me &amp; let me know if you would sell me one</p>
What about people who can't use PI? Also, would there be a way to turn the tv on?
You can use any programmer. Also, the remote works both ways.
<p>Could i cram one of those mini tv remotes with all of those codes on them into this or would it be too big? Halloween's coming up so I want to mess with the neighbors when I trick-or-treat at their house :3</p>
I actually thought of doing this before! Currently I'm working on a way to put a ton of stuff in my sonic... Well I found a way to cheat sort of. I just need more things to put inside it to make it more like the Doctors screwdriver. Currently on my list is:<br>A TV be gone<br>The remote starter / door opener for my car (when I get one),<br>The key card for my work,<br>TV remote,<br>Any more ideas?<br>It doesn't matter how big the item is, as I said before:<br>I've found a way to &quot;cheat.&quot;
<p>if you have a tv remote you don't need a tvbg. defeats the purpose.</p>
<p>What is this &quot;cheat&quot; you speak of?</p>
Is it possible to do this with every doctors sonic screwdriver?
<p>not with that stick the 2nd doctor used.</p>
I just finished mine, but I used river songs futuristic screwdriver. LOADS more space, I mean like two or three times more space. Just don't forget to take out the green dot underneath the psychic link display panel (below it as in if the emitter was pointing up) its hiding a screw. <br>
care to post a picture?
This is AWESOME!
Yes, for sure would $15 be good? I can also pay shipping of course.
Hey, would you consider making another tv begone circuit for me? I would pay you $10, my brothers birthday is coming up and he would loose his mind If he had one of these!! <br>Cheers
I might consider it. $10 is a bit low, can you go any higher? It was really hard to build and $10 barely covers the cost parts.
how much was the cost of the electronics, minus the sonic screwdriver, and the raspberry pi?
Minus shipping, around 3 dollars.
sou brasileiro (I`m a Brazilian Man) e achei show de bola, parab&eacute;ns.
that is so cool you need to make more like that thing <br> <br>
My dad has a tv-b-gone. And i love docter who. You just put two of my favorite things into one
As far as I understand this screwdriver is sonic &hellip;&nbsp;but does not drive screws in. <br> <br>Oh well !&hellip;I though that sound waves or something would help me when I had screws to screw !
No, it's from doctor who. It does all kinds of stuff besides driving screws. In one of the episodes, he used it to turn off TV's. I believe the episode was called idiot's lantern.
My bad. <br>I should watch TV more often ;D <br> <br>However I'm glad I gave you an idea about this sonic gadget that will help me drive my screw. Are you working on it already ?&hellip; We're all expecting it !!! LOL
Well, in one or two of the episodes, he DOES use it to drive screws.
I kew it ! I knew it !!!&hellip; <br> <br>And this takes the prssure off your shoulders tooo ! <br> <br>Thanks for sharing anyway ;)))))
I LOVE IT! <br>
I preeeeetty much love you for making this.
I am so proud of you! What a nice instructable! The drawings are so nice. I voted and faved! I hope you win! I am looking forward to seeing a lot more where this came from! <br>Have a splendorous day! <br>sunshiine
Well, please come back later, because I'm just waiting for it to get entered into the youth contest.
Hey furry, have you seen my minecraft tardis and stuff you would like it. check it.
Nice. I'll have to do some minecraft stuff sometime. I'm really good. You'd be amazed by some of my projects. I built a working digital clock in minecraft.
Your on! I will check back on Monday! Good luck!
Wow, this is really great work. You are well on your way to be a software engineer, hardware engineer, technician, and industrial designer! All wrapped up in one. Good job! Remember, the mark of a good engineer is not necessarily knowing all the answers, it's knowing where to FIND the answers that matter. It looks like you have that down.
Hmm... Just wish the folks over at hackaday thought the same thing. I was really hoping this would be cool enough to get featured elsewhere, but I s'pose not. I figured that would be enough to win the make to learn youth contest for sure, but they still haven't processed my entry yet. :-|
Be patient young salamander ;). Your time will come.
Wow, thanks a lot! It kind of reminds me of a comic I saw once, it talks about how this guys IQ decreases by at least thirty points when the internet is down. XD Anyways, I'm pretty good with logic, that's a skill that will help you all the time. All the kids at school wonder how I'm so smart, but what it really comes down to is knowing how to figure out the answers. I've seen them sit there for several minutes trying to figure stuff out, but they'll be doing it all wrong. You just have to know how to learn. And find info. Thanks again for commenting! And when I get accepted into the three contests, please vote for me again.
great work, a had this exact idea a while back
Hey thanks! After googling around a bit, I've noticed that a few other people have had the same idea too! However, I do believe I'm the only one to actually do so.
Very clever. <br>I use ATtiny's mostly without an external oscalator by choosing the 1 MHz option. Would this also run without one?
