Jewelry Box for Valentine’s day

Posted on February 12, 2016 by Kevin

Decided to make my wife a jewelry box for Valentines day. I’ll start with the finished product:

Design

Stopped by my local Rockler shop and found some hinges and a latch I liked.hinge  latch

Started designing in SolidWorks.

Final solidworks

Wanted to try making an inlay with Mel’s name on the cover with a combo CNC and laser cutting.

final closed

Needed a font with all rounded corners so the CNC bit would match exactly the laser cut part. Found one called “Days” on Font Squirrel that looked sharp.

Build

Thanks to my local makerspace, Crashspace, I used the CNC to cut the box out of 11″ wide walnut.

I made the bottom of the pockets with a dish carving bit, it has rounded corners and a flat bottom:

Switched to a 1/4″ straight bit to cut out the rest.IMG_20160208_140039

Bottom 3 layers and underside of the lid cut.

Test assembled with 4 oak dowels. So far so good.

Returned the lid to the CNC to cut out the inlay with a 1/8″ straight endmil. Looks nice and clean.

Laser cut letters and glued them in place. Not pictured, the laser cutter and individual letters. Forgot to take a picture of that. White wood is 0.10″ plywood.

Next up, the drawers.

Time to sand, sand and more sand. But starting to look sharp.

I did not account for the brass knob screw depth when designing the drawers, and it went way through the drawer. My fix, laser cut a little bit of black acrylic to hide the screw. Even helps keep the knob in place.

IMG_20160212_144103Added the final hardware and assembled.IMG_20160212_144125 IMG_20160212_144114

 

Used a little Wipe On Poly to seal the wood.IMG_3747 IMG_3746 IMG_3745 IMG_3744 IMG_3743 IMG_3742 IMG_3741 IMG_3740 IMG_3739 IMG_3738

Activity Board for my niece

Posted on December 19, 2015 by Kevin Jordan

I made an activity board for my niece for Christmas. She loved it!

Final product:

Final product

Started out last week with a goal of using stuff I had laying around the house to make an activity board for my 22 month old niece.

Found a few gears, a Sharp distance sensor, a micro servo, some light switches, an Ethernet wall plug, some LED lights, a counter, a fan, some buttons (from the musical chairs), and an extra break beam sensor from my cat wheel. I figured I could make something like my grandfather made for us when we were kids with locks and hinges but updated a bit with an Arduino.

I drew something up in SolidWorks then started cutting an old shelf I had on the CNC ShopBot at my local Makerspace, THANKS CRASHSPACE!

First round of cuts on the shopbot.

IMG_20151210_204455

Things fit pretty well. I forgot a couple holes for mounting the box, the break beam sensor wires, and the recessed area for the Near Far sensor’s laser cut acrylic protection.

Final set of CNC cuts turned out pretty well. Now for printing the mounts for the break beam sensor.

While that was printing, I laser cut the parts for the near far sensor.

Next up, wiring.

IMG_20151214_145039

This is almost all the wiring. I forgot to take a clear picture before I sealed up the box.

IMG_20151214_212315

Early test of the programming. I had to order a red button for the color wheel.

IMG_20151216_193055

Built a box at 12 degree angle so she can use it standing up.

IMG_20151216_202407

Complete!

IMG_20151216_202424

I used another piece of acrylic I had used for another project to seal up the back. The box is powered by a 12v DC adapter @ 1.0 amp.

The O-shit moment, I had to get this on a plane and had not measured my suitcase. Luckily I had a bigger suitcase laying around.

IMG_20151218_103220

My niece loved it!

IMG_20151218_212353

When she learned how to kick the foot pedal she was VERY excited.

Might need to learn where to plug in the Ethernet cable.

Thanks for checking this out. I was inspired from the reddit post “My daughters’s activity wall” and thought I could make something like that!

Thanks again to Crashspace for helping me make this happen.

This project was completed in 11 days, from inception (Dec 8th) to delivery (Dec 18th) so a few corners were cut. I’d like to make it battery powered but that got nixed. I also realized I didn’t bring out the USB connection to re-program it so I would have to unscrew the back to do that. Overall, a huge success with the niece.

Edit: Thanks oomlout for the great write-up on your site!

Activity_Board original

This is the original busy box my Great Grandfather made for my dad. We played with this thing for years as kids and my cousins still have it. Decent shape for being 55+ years old. It was the inspiration for my version of the activity board.
