Homemade chest display - esb

[hamsandwich72]

Just wanted to post some video of my (in progress) chest display. The 7 segment displays I have are too big and I will eventually have to move the whole thing to a "real" circuit board.

Enjoy!

nice work, what did you use to program the sequence?

 

[hamsandwich72]

An arduino (pro mini)

Your chest display looks great.

great!

Thank you. I really appreciate the feedback!

Technical update: I finally got the smaller 7 segment LEDs. They took forever because I (accidentally) ordered them from China. Plugged them into the breadboard and after a short re-wiring, the prototype is fully functional. (yay!) I've also been playing around with Eagle CAD to lay out the circuit. It's probably about 80% there. I printed it out and the LED's and Adruino fit the profile in the circuit.

Up next is to finish the lay out and transfer it to copper. Option A is to print the circuit on glossy magazine paper and transfer (via hot iron) to the copper. Option B is to have a friend print it on his vinyl cutter. Either way, after the transfer, in it goes to the acid bath for etching. (I'm very excited for this part)

Really cool.

Errrr. Well the image transfer didn't go so well. I got about 80% of the image transferred very well, 10% transferred so-so, and 10% didn't transfer at all. Tried glossy magazine paper and even tried photo paper printed at the office supply store.

Off to China they go for professional fabrication. Another update in three weeks or so...

The boards came back much earlier than I expected. They look great. Hopefully I can assemble everything tomorrow. Very excited!!

Great job next order service mount parts from mouser.com and get it micro sized

Yeah, the SMT stuff is a little beyond my abilities.

Bull**** it's not as hard as it looks if you get the board printed for surface mount it's easy

this is nice, need to make one for myself after I paint my chest.

Hey you should throw that up on instructables!!
that being said id love to see how you did this. I wanna try it
