Right, so the apple community fucks me over again. I didn't need a Z8603. I needed a Z86[b]1[/b]3. :suicide:

guess it's back to Butts Place, Russia for you

Meh. After torturing someone I learned that It's still useable for something else.

Damn solder bridges are the hardest thing in the world. BTW it's an isolated serial to RS485 board, if you're wondering.[/QUOTE] Out of interest did you scrape the solder mask off the board before you made those solder bridges?

[QUOTE=Cakebatyr;47639156]Out of interest did you scrape the solder mask off the board before you made those solder bridges?[/QUOTE] There is no solder mask on matrix board.

They DO come with a very thin coat of something or other to keep them from oxidizing before use though, don't they?

[QUOTE=papkee;47607629]So I've gotten the OK from the owner of the place to finally start posting photos of the power plant I was able to visit last year before it was torn down. I'm going to put up a full writeup here in a bit because I think that there was a lot of stuff there that you guys would find interesting. Here's one of the few rooms I was able to get a picture of. Yes, I have two of those guages and I'm making one of them into a clock. [t]http://i.imgur.com/WbsFl7a.jpg[/t] [t]http://i.imgur.com/CYJxDj8.jpg[/t] I only took about 20+ pictures while I was there and regret it to this day. However I got a ton of great stuff that really makes up for it.[/QUOTE] [img]http://i.imgur.com/CYJxDj8.jpg[/img] StacyWatts!

tip: if you got a fake arduino of any kind that needs manual driver installation, [I]don't[/I] randomly pick a device from the list of unkown devices if you got more than one and don't know which is the Arduino. I've managed to BSOD my computer by installing FTDI drivers on my usb hub :v:

[editline]1st May 2015[/editline] [QUOTE=Zero-Point;47640091]They DO come with a very thin coat of something or other to keep them from oxidizing before use though, don't they?[/QUOTE] That might explain why I had such a damn hard time.

You might want to look into buying some flux as well, can never have too much of that.

I can say with my boards I didn't have to worry about some factory applied coating.

You might want to look into buying some flux as well, can never have too much of that.[/QUOTE] I have had matrix boards with a small transparent coating that made soldering a bitch, had to sand the parts of the board where I wanted to solder a little bit before it would stick (and yes I had the proper solder and flux). Not all my boards though.

So I found some things. [IMG]http://i11.photobucket.com/albums/a166/ballsandy/IMG_9024.jpg[/IMG] Honeywell controllers might be useful for reflow ovens, the timed relay is exactly what I needed for a coin-operated timer and the buttons and relays....I got no use for yet.

Now you're talking my language. Where'd you get the buttons and switches?

where even would one find such things. They look really nice

I have my connections. [img]http://fi.somethingawful.com/safs/smilies/2/6/heysexy.001.gif[/img]

WAit, what? No. Not those connections.

Sex lasts only limited time, but components? Forever.

[QUOTE=Fourier;47645689]Sex lasts only limited time, but components? Forever.[/QUOTE] that magic smoke though.

It's an aphrodisiac, you know. Also, those Honeywell controllers may not prove as useful for re-flow ovens as you thought, unless they can be configured for temperature gradients for specific time periods. Controls like that typically are "is it this hot? Then shut it off, otherwise keep the fires roarin'".

I gotta double check the manual but I believe they can or at least, the manual has a worksheet you can graph something on relative to temperature. Failing that, use an external timer and relay to switch between controllers and thus temperatures. I seem to recall a CRT rebuilding service where the heat treating and bombing oven was controlled by pieces of wood that as it rotated over a 12 hour period the shape of the piece turned various things on and off using microswitches.

Yep. these have ramp/soak controls where temperature can be controlled relative to time.

Clearly we work with/have access to different levels of Honeywell controls.

I'm looking for some [url=http://www.digikey.ca/product-search/en?pv89=2&FV=fff40016%2Cfff80454%2C6c0008%2C1680001&k=pogo+pin&mnonly=0&newproducts=0&ColumnSort=0&page=1&quantity=0&ptm=0&fid=0&pageSize=25]0.050" pitch pogo pins[/url], except digikey is out of stock on them. I doubt I could effectively 3D print a housing for individual pins if I wanted to also fit them in the space I need them to. [del]Mouser doesn't even carry the 854/856 series >:([/del] Mouser's search function leaves much to be desired. Found the right stuff thanks to google.

Hello everyone, if anyone at all would be willing to help me plan out a small project involving some microcontroller (preferably a Teensy or similar, so i can interact with it over USB) controlling a single RGB LED, that would be greatly appreciated, contact me on steam or PM if you are willing.

Post in here, so more people can help you.

So I'm looking to get into some robotics projects with my arduino, but need parts. I'm making a wishlist on aliexpress (because holy fucking christ is aliexpress cheap as fuck), and so far I've got gears, resistors, servos, motors, some shields for the arduino. What are some things that are pretty much essential or otherwise useful? I've got a ton of tools, both large and precision, so that's not something I'm worried about.

Guns. Or lasers. Or [B][I]laser guns[/I][/B]
