Another boring DNA build

[BaDaBooM]

Laser cut !! wow
I'm (slowly) doing mine on a milling machine at work, but some nob broke the drawbar....so i'm currently at a standstill.
Know what you mean about the display (kid gloves) laying mine out so display and pcb are on the same plane to avoid stressing the ribbon.

I lived i Sweden for 22 years and moved back to the UK 9 months ago so I'm in the process of tooling up again, didn't bring any of my tools over . If I had the money I would get a decent mill, you can do so much more on a decent mill than you can with a laser. On a mill you can go back and adjust the cuts and get them just right. Lasers get inaccurate when cutting thick things and is only 2d, if the cut is wrong its scrap. I have a small mill now but its not the best and gives me fits, all I do on it for mods is the cut outs for the display window.

I think the sx350 is a better design and has dethroned the dna a bit (I was the dna's biggest fan). I didn't digg the tilt giro at first but now I see why its better, you can make a lot sleeker mods and its less parts. It come pre-soldered and the display isn't on weak ribbon.

Have you made a thread about your mod or mods you have built ??

not yet, taken some pictures of the build as it progresses but its a slow process and would rather post it "complete" as it were.
So far its all recycled materials, PTFE mahogany, alu/brass alloy and stainless....though recently have been side-tracked by PTFE drip tips
as the lathe is still serviceable, LOL.

Ordered some copper plated silver wire that came in the mail today, it was as soft as lead Ill have to stick with copper wire.

.... You have access to a laser cutter? God I am jealous. Have a million designs in my head that would be Sooo easy if I was still at my old college

Update 3

I started on the battery contacts, usually I leave more for then but for some strange I didn't for this build and it a major PITA.

made the + battery plate, took some cooper plate cut it to size and then used a punch and hammer to extrude the + contact. Drill a hole and copper wire in the hole.

Soldered the copper wire in place. I need the copper wire so I can solder the battery wire to it later and shrink wire it later.

On the back side I hammer the wire flat and solder it.

Was going to add lots nice pics on how to make copper battery springs but like I said on the build I didn't have any room for a proper battery spring. I'm going to add some info anyway.
Copper is soft and you can never really get it really hard and springy but you can hard enough to make "ok" spring. This is how I harden copper wire (remember heating copper and then cooling it doesn't harden it).
Get some 1.2mm copper wire, cut a 10 cm length, use something like a cordless drill with 0mm chuck. Now but the end of the wire in the chuck and tighten, grab the other end with some pliers, pull tight and with slow speed on the cordless drill twist the wire, you see it start to twist to about the middle of the wire, when you see this take the wire out put the other in the drill and do it again with the same rotation. The copper wire is now hardened.

To make the spring requires some practice, many ways to do it (search youtube) the way I do it is with jewelry pliers. To see how to work wire this way their is plenty of videos on youtube.

Next I drilled the holes for the +/- buttons. Pretty straight forward drill 2 holes.


I used standard tactile switches because I'm sick of seeing the round silver ones. Test fit to see everything fits snug. Will fix so they don't protrude so much later.

Wiring time.

So many wires for such a little board.

Here I had pulled most of the wires where I wanted them to go.

Just a quick check to see if the board was still alive.

Soldered the plates, could have done a better job but I just wanted to get it done at this point.

Tidied up the wiring, checked so it powered and so the +/- buttons work.

Near the end of this build not much left to do

Drilled the hole for the firing button and the 510 connection.

Next to my 2x 18500, a little taller.

All the soldering done, needs stripping down, sanding and maybe a staining.

That, Sir, is a work of art!

 

[BaDaBooM]

That, Sir, is a work of art!

Thank you, means a lot.

Might start making and selling these on a small scale if I can source some decent 510 connections. Would never sell anything I made if the quality was sub par.

Very nice build
