Step 5: The Box

I needed some kind of inner lid in the box so that it's innards wouldn't spill out or be seen because it really looks awful in there.

I took a CD case and cut out a fitting piece of plastic from it and spray painted the bottom of it with a golden color leaving a hole where the display is beneath it. It really didn't turn out that bad for this application as a LoveBox. For a DecisionBox as a gift to a CTO maybe a some other covering would look better.

The box should be turned on when it's opened. But most switches are activated when pressed, not when released, so I tried to make my own switch using a safety pin that would be pressed down when the box is closed and springs back up when its opened, but I didn't succeed with it.

After a bit of rummaging in my junkboxes I found a miniature microswitch that has both a normally open contact as well as a normally closed. After fitting that switch in a corner of the box it worked like a charm.
<p>I think the video links are broken. I'm not able to watch either one.</p>
Excuse me, is there another way to do it? I can't find the display anywhere:c <br>If I do it with a 16x 2 LCD display...Can I do it with that microcontroller? Do I need another one?
can this be done with an arduino <br>cus i cant understand C
Where did you get the datasheet for the alphanumeric display? I bought some off eBay and they say &quot;IF = 7 ma&quot; but you mention 2ma above. Can you post the datasheet here? Thanks
Sorry, it was a long time ago and I've moved to a different continent since. But it seems like most specs for the TSA1605A says 7mA which doesn't seem unreasonable...<br><br>TSA1605A<br>Three-Five Systems, Inc.<br>Search: TSA1605A<br>Segmented Alphanumeric LED Display - Clear,Bubble,2x<br>Package Style (Basic)=2-Edge+Hol<br>Number of Characters=8<br>Connection Type=Comm Cath.<br>Color=Red<br>Character Height (mm)=4<br>Peak Wavelength (m)=660n<br>Iv Min.(cd) Luminous Intensity=450u<br>@I(F) (A) (Test Condition)=7.0m<br>V(F) Max.(V) Forward Voltage=1.8<br>@I(F) (A) (Test Condition)=7.0m<br>I(F) Max.

Just as an FYI the box you used for this project it is actually used to keep the hair of a one of the kids when they pass away under the age of 10. Usually this box is only used by the pastor. I found this picture on google images and i thought it was unusual that you used it in a project.
how do we program this thing????<br />
Finally made one myself :) Yipee!!!<br/><br/>Made few customizations:<br/>LCD 16x1 screen without backlight { for power consumption }<br/>based on PIC16F876A { coz I'm into PIC world =) }<br/>PCB<br/>ICSP connector { for future firmware updates :) }<br/>low battery indicator<br/>embedded battery charger<br/>17 messages { hope this enough }<br/><br/>Some photos below<br/>
Could you explain the purpose of the 74HCT138 and how it works? Why couldn't you control the display with the uC? Thanks.
The 74HCT138 is used because there aren't enough output pins on the &micro;C to control <em>all</em> the pins on the display. The 74HCT138 is able to individually address each of the 8 display sections using only 3 pins of the &micro;C, instead of 8 &micro;C pins.<br/>
For those of us that are are not as comfortable with circuitry, you could buy a cheap voice recorder (sometimes available at the dollar store) & record a few seconds of "I love you's" then just use a simple switch to activate it when the lid is opened!!!
Is the box made of camel hump? I have one almost exactly like it, and mine is! (Well, it's from a friend's dad who was in Iraq.)
It might be. I've never seen the inside of a camel hump but the material beneath the brown paint/dye on the outside had a off-white bone like color and emitted an disgusting burnt hair-like odor when I Dremelled it.
Hi, First off, this is a great project! Thank you for your post. My only complaint is that the instructions are a bit lacking in some places. This leads me to the question...where do you solder the power supply at? Also, is the code that you posted the edited version(the one you tweaked due to you soldering some resistors in the wrong place) or will it work if the resistors are attached as shown in the schematic? Thanks!
hii need help making this can you help ple i whant to make it for my gf
Ok, what kind of help do you need?
I think its great and don't you think you should add romantic music
sound really confusing :&
you must have some time on your hands. just buy her flowers. the results are the same.
the results would not be the same. flowers take little thought/effort. a woman is much more touched and impressed by taking the time to create something personal.
It only took two evening to make this, and it's fun to actually do something physical. My days are usually spent reading and writing reports and attending meetings so this is an welcome break from that. Besides, if I'd buy her flowers she probably just suspect that I had been cheating on her.... :-)
that, plus this is way better than flowers. they know the difference between you taking time to do something, and you putting absolutely no thought past "this bouquet or this one?".
This is just a brilliant idea, definetely gonna make this soon :)
Thanks, I really enjoyed your work.
WOW! Good job! This is quite inspirational.
God Jul! Someday when I have a little more money and time, I'll have to try this one out. I really like the display, it almost gives a steampunk feel...
Most Awesome! Wish you presented this earlier. Well there's always next year!\\ Peace and Joy be with you and your family the Holy and Joyous season.
Make sure to tell her you love her when she unwraps it! Nice idea.
Very nice - I just hope your wife doesn't read this site, otherwise the surprise is ruined.
Aww, nerdy love! Great idea. It will be a hit for sure!
Wonderful! You did an amazing job cramming all that in such a small space. <br/><br/>As for &quot;it's not like anybody will notice it anyway&quot; - if your wife ever <em>does</em> have a peek inside, she'll just be even more amazed at your god-like powers of nerdiness! :-D<br/>
amazing! i would do this, if i could.
Really a nice idea and I hope the wifey loves it! Soldering it dead-bug style like you did requires brain power! The last picture reminds me of the time I had to make a Slot Machine for school. *shudders*
too confusing for a regular person but the detailed instructions and good pics should help ty
Yea, I agree that it's not for the Average Joe to build this. Without a good deal of soldering / electronics building experience it'll be very hard to duplicate this project. It's mainly meant as an idea of what you could do with a nice box and some electronics tinkering in an evening or two. If it could be sold as a complete kit with all the parts including a suitable box and a PCB to the "general public"....
