Are embedded systems welcome here?

I'm looking to buy my first development board,
and I've been looking at Particle Photon (pic rel):
https://www.particle.io/

Or Nucleo something, like F401.

I'd prefer it to have WiFi capabilities.

Can someone help a newbie out?

I honestly don't know much but I have an Arduino that I'm just starting out on.
Some anons here will probably shit on it for being a meme board but who cares.
It's got a fuck ton of support and parts for it.

>>916430
you want wifi capabilities?
Go with the Raspberry Pi
or the LinkItOne
The raspberry is getting cheaper
the linkitone is a bit out of pocket, but its works with a lot of the native Arduino stuff. API and Shields. LinkItOne is really powerful for being small. But if you're Just starting i suggest Arduino all the way. It's great to get started in the field of embedded systems
>>
also make sure to check out maker sites! They always have available projects that one could get started in. Instructables is one good example.

Don't be afraid to ask questions.
But don't be stupid and not try to figure it out for yourself first.

General rule of thumb: try to debug it yourself first and google. 9 times out of 10 the answers are already answered. Look before you ask something that's already been asked. I can't emphasize this enough. You'll get looked down on if you newfag too hard.

110 KB,
I'd like to design ( and then build ) my own tiny house but have no clue where to begin. I have ideas ( protective window shutters with solar panels that close over the window for travel but can open/angle downward so the solar panels can collect light ) but have no clue how to incorporate them into a blueprint. That assumes something like that even belongs in a blueprint; I'm pretty fucking clueless and need all the help I can get.

Hi again, anon.

I just found this image and wanted to share it; I was thinking of something along these lines but with solar panels that would face the window when closed to keep them safe during travel. I was also thinking it would be nice if, when facing outward, the shutters could be tilted at an angle to help catch sunlight. I don't know if I would need a track system for something like that though.

But my guess is that is a bit far off into the future. For now I just need to know where to start in the design process. Would I use MS Paint with a grid and/or...

Learn how to make your own panels. Save lots of cash by making a 40'x40' panel in one go then cut shapes as required. Then rivet/screw/bolt them into place(locktight if bolting).

A panel is something like buying a long piece of weatherproof plastic and adding layers of material like floor polish/polyurethane and the like. Application pending.

Exterior should be metal or wood.

Before you waste too much time, ask your teacher first if it is allowed, safety etc.

you really only have to protect yourself from the 120V primary, coz the secondary is just a couple of volts. so, if you cover the 120V terminals with heat-shrink or tape, the rest is relatively safe, unless you nicked the primary wires, exposing the copper.
as for welding goggles, you dont need them. it shouldnt be any brighter than birthday sparklers.

So due to horrible placing of outlets in my house. I have two computers hooked up to the same outlet, including their periphirals (monitors, speakers etc.)
When flipping the psu power switch to "on" I noticed the monitor on the other computer for a brief second either losing signal or having a small static line appear on it.
So my first insticnt was that there was a faulty cap on the power circuit in the monitor letting thourgh dirty power.
I switched between the monitors and sure enough I couldn't reproduce the issue.

The blue spark was probably static and should have grounded out through the monitor frame. I wouldn't expect any problems.

As for the other issues, there is obviously some voltage changes happening in your household circuit. The Power Supply should absorb minor changes, but that will burn the PSU itself out pretty soon.

Easiest solution (aka, not rewiring the house) is getting a Power Conditioner or Universal Power Supply. Should be 100 bucks ish. Well worth it to protect your hardware if you suspect dirty power.
>>
I think you're over reacting to a point that you're not seeing things clearly. If nothing's wrong don't go looking for something. I'm not trying to come off as a dick, but it really doesn't seem like there's an issue. The line could have easily been a capacitor charging up, and trying to replicate it didn't work because it already had its charge.
>>
It's probably not a problem.

If it's worrying you, get a small UPS for each computer. The controllers for them have gotten much cheaper, and better in the past few years. Even the bargain model will probably have some automatic curettage regulation. This will protect your computer from momentary (to fairly short) dips in power, and for power outages laying maybe ten minutes. That is plenty. The bigger more expensive units give you more time on otherwise identical equipment, or the same time on bigger equipment, and you won't need that. The batteries are...

>>917228
the later p80 v70s had a signal wire that gave you the speed for things lke changing the radio volume that you could have used but that was with the ETM, i don't know what an old 850 with a traditional throttle is like.
but essentially you figure out how the speed is communicated to the dash on the physical and data layers and build a system to analyse and display the result.
pretty much any microcontroller could do this with perhaps some additional circuitry to convert voltage levels to something suitable.
couple of shift registers and a handful of leds to display the output. possibly some hysteresis in the micro code because the last thing you want is lights flashing at you distracting your attention when you drive.

Guys, I've got this motor on a snowblower and it will only run with the choke halfway on. Summer or winter, BTW.
I took the carb apart and put a rebuild kit in it. Then I bought a whole new carb.
Exactly the same thing! Not a bit of change with a whole new carb.
Any ideas? Thanks.

Is the manifold 100% tight? Maybe it gets some air through the gaskets. Head gasket failure? Is the spark plug sitting tight - is the thread ok? Does it have good compression?
If nothing of above helps it may be a mechanical problem - the cylinder and piston rings could be worn out.
>>
A lean condition is what requires you to apply choke. That's typically an air leak and you eliminated the carb by replacing it, but it can also be a mixture adjustment.

Example diagram, find your fuel mixture screw.

http://www.oldminibikes.com/forum/honda-clone-predator-engines/48946-adjusting-gc160-governor-reduced-rpms-2.html

I suggest opening the fuel adjustment screw a quarter turn at a time and running the engine. You can start with the choke but of course the objective is "less choke, more fuel" until the engine runs correctly.
>>
>>917081
Dump the gas, check the in tank fuel filter. It's a replaceable part, but you may have issues finding one locally.Clean it if needed, refill with fresh gas.

Now check the small bowl below the fuel shutoff lever, make sure it's not full of crud, and make sure the fuel flows freely.(a 10MM boxend wrench will do the job for most carb work on common Honda mills.)
If it does not flow when moved to "on", remove the fuel cap on the tank. If it suddenly flows, you need to replace the cap, and the carb is likely fine. (Some of the Honda EPA/CARB complaint fuel tank caps are notorious for not venting properly.)

Otherwise pull the main bowl and make sure the float is not stuck and that there is not a bunch of crud in the bowl. If you have corrosion or similar in the carb bowl and it's obstructing the main jet, you're better off just replacing the carb as a unit.

>>917269

The carbs on most of those Hondas are not really adjustable like an old Tillotson or similar. The base idle speed and to a very limited extent the idle mixture is all that you can adjust.

So like.... a motion detection camera that sends you a snapshot or video stream when it detects a critter? I think that's fairly doable with a Raspberry Pi.

What kind of range are you looking at? And what are you going to use on the receiving end?

Battery is going to be a problem. A pi will take to long to boot and miss whatever it is supposed to be recording. Running it all the time will require too large of a battery to run for days/weeks like a commercial trial camera.

So a year or so ago I came to you guys and someone walked me through fixing my refrigerator. This time the thing is completely done for and I've got no choice but to buy a new one.

I can't believe I'm saying this but you guys are the only ones I really trust for real advice (reviews on home depot and Lowes smell of paid reviews and whatnot). So with this I ask....

Given the choice between a GE, Maytag, or Frigidaire which one would you guys choose? Keep in mind this will be closer to the bottom of the barrel as I had to replace a washer last week....

GE would be my guess from a business standpoint. No idea how Frigidaire is doing, but Maytag has lost its brand recognition with younger buyers, and surely sales suffer as a consequence, which means a cheaper, crappier product. GE is still huge, and can afford more in the way of R&D. FA may be owned by a bigger company.

Also, if you're rich, I recommend Traulsen. They're expensive as fuck, but I can personally guarantee you a life span of 20+ years in a home environment.

They prolly come out of the same factory to be honest. I haven't been brand loyal for years, I simply set a price range I can do, make a list of "must have" features and a list of "would like" features, then see what I can find in the price range specified. If a "would like" is only going to push me out of my price range by 40 odd bucks I'll stretch, otherwise this system seems to do the job for me.

Possible bad CPU, or your CPU is incompatible with your board. Check the list of approved hardware for your motherboard (should be able to find it on the manufacturer's website) to see what CPUs your board takes, and what BIOS revision you need for it to take them.

In some really shitty cases, your board's box will say it supports some new family of chips, but then the manufacturer puts an old BIOS revision on the board, so you have to get an older chip, flash the BIOS, then put your new chip in.
