For the love of humanity, why.

Its worse than some of the worst BEAM robots.

[QUOTE=Leestons;47989070]The problem with my iron is wherever I clean it on the sponge the solder just balls up at the point. Probably because of the tips shape.[/QUOTE]

What shape tip do you use? Also, I sometimes have that when my sponge is too wet. Try making it just damp instead of soaking it.

Pentium didn't want you guys to know he's an idiot.
He's an idiot.

[Papkee]

That honestly looks like someone put a pcb through a shredder and then dumped a cup of solder over it.

It's art, really.

[pentium]

I....what? :v:

Yey, got my directional bridge! :dance:

In the event you have spare RF equipment, I will happily take it off your hands.

You've seen my hauls. You know where to look that's only three hours away.

So Nikomo's keybounce code worked well but there was still really bizarre issues. I was burning out MAX232's with latchup, the micro was triggering for the most isolated things like turning the modem on or off manually and I could see nothing on my analog scope.

Solution: More capacitors! Additional filtering and decoupling was added and that cleaned the problems up real good. Also added some flywheel diodes I forgot. Now it's nice and responsive under all conditions.

Now all I need to finish scratching my head over is the damn telephone circuit.

There's still fucking latchup. What the fuck?

I use the conical tip that came with the iron as I haven't bothered buying a chisel tip yet. Maybe the sponge is too wet, I usually run it under the tap and then squeeze any water out with my fingers.

I don't really drive far but damn it's useful for shit like this.

Does anybody know much about bluetooth and if it supports analog (eg a joystick) values.

I've got an old wii classic controller that has a ton of extra room and I would love to convert it to a bluetooth device of some kind.

...The classic Wii controllers used bluetooth as a standard. You can even use it as a controller with GlovePie (glovepie.org) on your PC.

Oh, I've been doing that for a while already. I just wanted a compact solution that didn't need the wii remote at all. Like the [URL="http://ecx.images-amazon.com/images/I/7115A2m702L._SL1500_.jpg"]wiiU pro controller. [/URL]

Ultimately my point was that yes, you can send "analog" values over bluetooth. (ADCs or Analog-Digital converters are what you're after)
Or there's this:

[Papkee]

Yep, I know all about it. I'm actually using his other project, WiinUSoft, because it emulates an xbox controller which has more compatibility with the emulators I use.

My question was more could I throw a bluetooth adapter and an arduino into this controller and make it wireless and it seems like the answer is yes.

Teaching yourself a CAD program is grounds for a massive head-ache.

Designing screws both on paper and in AutoCAD is a nightmare, especially when trying to adhere to ANSI standards...

There will be all-thread and one Acme screw in this design, ya wanna know how I'm going to do the threads in FreeCAD?
[sp]I'm not, fuck that noise, I'm just gonna use plain-ass cylinders.[/sp]

Machine screws & nuts are a godsend.

I built a portable Speaker yesterday. First i have used an Bluetooth receiver, but i had some weird noise. i replaced the linear regulator with a buck converter, but had the same weird noise.
now i decided to just use default 3.5mm jack, which is actually better when using my smartphone. i can turn it louder and such stuff.

The main parts was:
2 Magnat Monitor 110, i removed one Side of the wooden housing on each speaker, glued them together, added a bass reflex port.

2x100W class-D china amp, which is actually pretty good for the price and size, i was suprised.
2x crossover(the original ones)
few wires and a bridge rectifier, so i dont have to worry which way i connect the batteries.

It will be connected with 2 screw heads at the top, where you can feed in 12 to 30V DC, perfect for 2 Lead acid batteries.

Now im looking for a carry handle, and a proper battery housing.

Maybe someday, i will replaced the bass reflex port with an passive-membrane

Did a simple board last night, to get used to KiCad.
Then I plotted it to Gerber files.
Then I ordered the PCBs.
Then I bought the parts.

I guess I'm building it. I don't need it, but I guess I'm building it.

The 3D render looks pretty.

Let there be light!

wrapped LED Strip lights around an old pirouline can.

Needed 12v power supply. Don't have one. Made a paper tube and put 7 (couldn't fit 8) AA 1.5v batteries in it.

Wiring. ignore Arduino. Just needed the prototype board and didn't want to unscrew it from the arduino enclosure

[editline]23rd June 2015[/editline]

When I get my tip120's I can control the color of the lights using the arduino.

5 dollar Geiger tube, expires tomorrow, it's like at steam sale price.

[Leestons]

Made a circuit, tested it and it worked fine. Drowned all the connections in hot glue to prevent shorts/ wires coming off, doesn't work...:suicide:

[gamerpaddy]

And heres the video, if it doesnt work, wait. i just uploaded it.

Random content until my paycheck arrives so that I can buy new parts for upcoming ~~Uber-Cool-Switch-Mode-From-Near-Scratch-Bench-Supply~~ (Temporary Name).

Found an old ATX supply, reused it with some nice banana jacks/LED and ran out of room to stick the fan back in. (Also the dummy load resistors, to hold regulation, can get rather hot so I may need to up the resistance on them..)

I like my wire management job:

I needed a hefty 5V supply anyways so I can play with my RGB light strip (10W at max):

Sooner or later I'll have a non-potato quality (my phone) video recorder...

[Leestons]

If I didn't already have a PSU I would make one out of a computer power supply.
