/diy/ - Do It Yourself

Lurking, post more pics pls.

what would you like to see? I've invented lots of cool stuff.

Circuit diagram of the clock _you_ invented.

>>1328556
He seems to have several laptops and parts organisers. Maybe he did have a part in building the clock.

>>1328563
>Maybe he did have a part in building the clock.

what do you mean maybe. I went to the White House bub.

I just got a nixie clock kit, with the bulbs and everything. I never really thought about the size of the parts and how small they are. Now I'm worried about soldering it all, cause they're so smol...

>>1328569
proper tin width and a sharp tip in the iron will suffice.

>>1328556

>proper tin width

WAHT DOES THAT EVEN MEAN

>>1328573

I didn't vote for you so stfu.

>>1328575
Do not use too thick tin

>>1328576
>Do not use too thick tin

are you referring to the diameter of the solder or something else

>>1328536
I'm currently making a nixie tester to test various modules and concepts before I make the final 6 digit clock. I still have to test the temperature sensors and the RTC, but the power supply and control is all figured out.

I'm retarded and forgot to invert the transparency. Just....

>>1328579
why do people insist on making PCBs at home? It's like $5 for professional quality boards online now.

>>1328583
It's about making things and learning from errors.
like, you know, diy.

>>1328536
I am way to dumb for this.

Bamp for badassness tho

Orly?

Nice

>>1328583
Sweet, where?
Last place I got pcbs made cost me way more than that.

>>1328583
I only make small boards like those, although I agree, it's too much of a hassle. I'm going to order some PCBs when I have the final design of the clock.

I've never ordered PCBs before and mine will probably be 15 or so cm by 4 or 5 centimeters. What page do you recommend?

>>1328536
here's my project, time is synced via the Internet, and you can hack it to display anything you like (it's open source)

>>1328652
That is fucking sweet anon, I especially like the finish on the wood.

>>1328652
You got a link to any details? I like the finish

>>1328652

That finish is excellent.

>>1328652
The finish sucks. Not only did you not fill the grain but it looks like you put 2 coats of tung oil on it and called it a day.

>>1328652

How did you get the finish so nice, anon?

>>1328600
>>1328619
OSHpark . I use KiCAD because it's free but they take lots of types of files but they take KiCAD and EagleCAD directly without generating Gerber files separately. A square inch, 2 layer, board costs $5 for 3. Bigger will be more expensive so probably doesn't make sense to do in large volumes but for nice prototypes it's good.

>>1328683
>OSHpark
That's 5$ per square inch, those boards would've cost me 40$ compared to the 4$ I've spent /diy/ing it. And I would have 2 extra boards which I wouldn't need.
It would be nice if I could order just one PCB, but so far I don't know any manufacturer who does this.

Thanks! The piece was CNC machined and finished with oil.

you can use:
pcbway.com
seeedstudio.com

All of these are way cheaper than OSH park. Quality is good

You're aggressive because you're jealous of his success. Show anything remotely better to what he made. You won't because you're a bitter failure who thinks he's better than everyone. Maybe you're just in a bad mood, but fuck you for trying to put down a man when he shares his productivity. What you did was evil.

He didn't even say anything about the finish. You just decided to shit talk it because you got jealous of everyone else's compliments.

>>1328579
just drill, liquid tin over all, strip the resist, and etch, kek
nice exposure doe

>>1328758
>wanting just one board
the cost of a board is > 90% setup, < 10% materials. take the extras, they're almost free. you now have spares for process experimentation or a paste stencilling jig

That's a interesting idea, what do you use to power it?

Allpcb have done a deal with DHL so you are only a couple $ more than the cheapest but get delivery in a few days.

Damn shame its now Chinese new year holidays for the next two weeks :(

I don't know much about clocks, dick masterson built a pretty good one for burning man though.

A small lithium Ion battery like what a cell phone uses. It goes about a week before needing a recharge.

>not including body temperature monitors
noice
you might get better battery life and "adequate" timekeeping by using a "tuning fork" crystal to run the CPU

>>1328579
I finally got it right and applied the solder mask, 6mil minimum trace width. Now comes the painstaking task of cutting, drilling and populating the boards.

>>1330565
Pro tip, don't solder the pins with the nixie still attached, they solder on the nixie's pins will melt and attach to the pins, so you'll spend half an hour trying to remove it with a hot air station, being careful not to rip the traces in the process.

>>1330565
berry gud. what did you use to apply solder mask? what solder mask did you use? also y u no spincoat?

>>1330757
I use uncle Ho ching's traditional recipe. I just laid some film on top of it and spreaded with a card, as noted by the uneven results.
>also y u no spincoat?
Shit's nasty, I don't want it all over the place, also I would have to place the film and transparency on top after that, and it would be hard not to ruin the finish while doing so.

>>1329045
Tell the time AND control temperature on furnaces
Smartwatches BTFO
(I do unsarcastically think it's cool)

>>1328583
1. Because /diy/
2. Because those cheap Chinese PCB shops take weeks to ship you a board, which is fucking useless for rapid prototyping.

>>1330738
>don't solder the pins with the nixie still attached

No, don't do that. That would be really really stupid. Why would anybody ever do that?

Why not build a jig using male pins on another piece of board?

>>1328652
Your numbers are wrong friend.

Don't let the dream die anons

>>1328566

>>1328583
>why do people insist on making PCBs at home?
You can make a simple two layer board within 1 hour.
Ordering one for $5 will take weeks to arrive.
2 weeks = 14 days time 24 hours = 336 hours.

Thus making a board yourself is 300 times faster.

>>1330898
Bump. I tested the control board for the first time, everything seems fine and dandy despite smoke coming out of my attiny after connecting Vcc to one of the digital pins and Ground to the Vcc pin, I'll probably change it anyway. Still waiting for those SMD resistors from aliexpress, so I only need to attach the PSU and I'm done here.

>>1335296
Atmel: takes a lickin' and keeps on tickin'

>>1335770
Yeah, after the smoke I though it was done for, lol. I probably just destroyed the zener diode of that output. Good thing that output isn't in use.

>>1335296
I've finally finished it, I'm using the wrong resistor and the PSU is around 30-40% efficient, but it works. I'll leave it running overnight to see if anything catches on fire.

If everything goes according to plan I'm going to start working on my nixie clock, maybe using the HV5812, which is at 10 cents per output compared to 16 cents per output if I use 74HC595 + ULN2003, also less hassle with placement.

>>1335909
Now I need a supplier that doesn't charges me 20€ for 10€ worth of IC's. Some guy told me about some polish electronics supplier, but I have forgotten since.

>>1335909
My math is wrong, 0.27 per shift register and 0.30 per transistor array. That is, 8 cents per output, or 5.37€ a 6 digit clock, including dot. The cheapest option I've found.

>>1336180
consider discretes. MMBTA42 for a cent each in 100s + base resistor for $2/1000 (aliexpress prices, may vary by country)
the HC595 happens to be popular because it speaks a protocol that strongly resembles native SPI. there could be other shift regs in the HCMOS logic universe that might need a slightly different protocol. in particular a tiny, tiny bit of flicker as a bit works its way down the register line might not matter too much if you're quick about it, in which case the HC164 would be worth considering

>>1336207
>consider discretes
I did, but it'll probably be a pain in the ass having to place and solder them all without a reflow oven.
>HC164
It's 10 cents more expensive than the 74HC595 on digikey.

>>1335296
>>1335909
Lol, they saved money by making the 5 with a rotated 2.
