Tried google. I found similar but not mine. Anyhow I bought an 09 fifth wheel. What I thought would be the easiest project has turned into a pain in my ass. To save money I'm cleaning the blinds but replacing the valence. I got the side boards off. That was easy. But I can't take the top off without removing the blinds, can't figure out how to remove the blinds without removing the valence. Soo. Im stumped.
I need to create one of those simple heart monitor you can put on your fingers. All the information is right here in the link and the LabView code is already finished, but I'm an idiot so I don't understand how I'm supposed to make the hardware. Which is pretty stupid because you only need a led, a photoresistor, a shunt resistor and some type of filter which I don't understand.
>>997661 google potential divider for an ldr/shunt resistor circuit.
google passive bandpass filter Capacitors pass AC and block DC, so if you have a capacitor to 0v it will short out AC effectively blocking it. a capacitor between input/output will block DC from reaching the output but pass AC to the output. You should do a little research on signals if you want to learn more, look into fourier etc, all signals are made up of combinations other signals etc.

So I'm going away on vacation for about a week in july and I'll have a number of plants (tomatoes etc) sitting on a covered deck that need to be watered at least once every day or two.
The best thing I can think of to water them while I'm gone is a pump on a timer that'll draw from a large reservoir (one or more 5 gallon buckets, I have a lot of vegetables in pots to water) to water the plants every set amount of time.
The problem is that my deck has no power outlets to power the pump and I have no windows that lead to the outside that I can run a cable through.
I live in a brick apartment building with what appears to be holes cut through the exterior brick for fiber optic cable insulation; two rooms in my apt have these wallplates that 'appear' to be heading outside onto my balcony that carry these cables.
Would it be feasible to put an extension cord through one of these to the outside?
Does anyone else have any good ideas as to how I could rig up a system to water my plants? I'd prefer not to ask a neighbor to come over everyday if possible.
>>997369 I've used battery operated programmable hose valves (Battery Sprinkler Timer) before and the batteries for what I had lasted quite a while and would definitely last a week, seems mine lasted over a month if I'm remembering correctly. If you can prop up the water reservoir you could rig up one of these to release water. You'd need a garden hose connection off of the reservoir to the valve then a manifold (PVC pipe and hose bibs) off of the valve that distributed water using enough smaller hoses to reach...

>>996731 >what kind of resources would be needed to make a ship the size of pic related. If you have to ask, you don't have them. Unless you have an entire forest of old-growth hardwood just lying around, you won't even get started. What's your budget and timeframe?
Anyone know how to fix this wire that got cut outside by accident. I have no tv or internet. And I don't want to get charged by verizon to do this. All I could find so far was this: http://www.instructables.com/id/Repair-a-cut-TVinternet-cable/
but that's for a round coaxial cable. How do i do it for a flat coaxial cable like this?
Does anyone know of anyone that still makes old school power switches/buttons like this? I mean with the art deco styling, not just a beefy on/off switch. I'm restoring a few vintage machines that had all of their power switches replaced with standard light switches and they look like shit. EBay has them of course but they are $60+ and I don't have the budget for that.
get ready to burn / explode some large package transistors > magic smoke? alligator clips? what are heatsinks? its pretty advanced stuff cause of high power look up someone else who has done and use their schematic. build it like they do and listen to their considerations https://www.google.com/search?q=plasma+speaker+schematic
>>994095 >but I don't know enough to follow schematics and stuff.
Please stop. That's like saying you can't follow instructions by Ikea. Also "i don't know enough about x" is a shitty mentality to have if you want to learn a trade. If you don't know something, you look it up. You look up schematics, other people's experiences, order parts, put everything together on a breadboard, test and then solder onto a either a custom PCB or a prototyping board.
>>994095 >Will I need anything extra? The main component of every plasma speaker is a flyback transformer, they can be obtained from old CRT TVs and monitors. Also a power supply of 12 volts or higher and 3 amps or higher. Anyone know any super easy noob friendly guides? Not that I recall, but the easiest circuit you'll find with decent performance is the 555 based one, I'll post the schematic when I get home.
I highly recommend you try to play with discrete components... Comment too long. Click here to view the full text.
I never had a shop class available to me during high school or college. So i have volunteered to do some work with habitat for humanity in hopes of learning how to do some basic house things i.e. framing, siding, insulation, landscape, and painting
any other good charities or companies i can volunteer with to build my /diy/ skills??
>>987039 Going to school and getting a job are typically the ways to acquire skills. You're relying on a bunch of know-nothing volunteers building budget houses to teach you shit? I'd become an apprentice before I do that.
OPEEE you gotta start it off with something to talk about. Like anvils, favorite hammers/tools, charcoal vs coal. Blacksmiths hate him, 1 neat trick to make your anvils stop fucking ringing so loud you wish you could buy a suppressor for it
Alright so I picked up a 1978 Yamaha 250e for free. When it was kick started, you could hear a faint hiss. I took the engine off the bike and removed the piston, which was cracked. (pic related) I installed the new one. Moar to come\/
I was going to buy a document scanner to start scanning all of the receipts I generate through my business, but instead I was thinking of just using my phone. Some of the documents have been wrinkled, so I was considering using Lexan or something similar to help flatten them for taking pictures. I am worried about a glare, however. Do any of you have recommendations or suggestions?
>>997650 I thank you most respectfully for your extensive answer, despite of the insufficient information provided in my initial post.
I'd work with a 12v DC Fan with about 10 cm diameter, because i'd like to use the same power supply to power LEDs, so in any case i have to get down from the 220V in the network. Of course the LEDs have different needs that have to be treated in a separate circuit from the 12V power supply.
>>997500 If you already have a multimeter then why do you need a new one? There are better things to waste money on. If your job/life depends on it then get a proper multimeter. 30$ won't cut the mustard.
So i want to build a cooling using a refridgerators compressor, using a fpga or a micro-controller i will develop a control system that will regulate the temprature based on the feed-back. >>Help me get started >>what would i need >> what prerequisite knowledge and skills do i nee to aquire >>some sites and books that could help me
>>993889 Computer engineer here, your project is completely pointless. The whole point of cooling is to keep the chips in a certain temperature range and this can easily be achieved with air or water cooling. There is no point in going below some temperature, so unless you live in an oven, a compressor is fairly pointless.
However if you insist on it, you're going to need: >Microcontroller just use an Arduino >Temperature Sensor Either... Comment too long. Click here to view the full text.
>>993925 op here people have gone to extents of cooling using liquid nitrogen so a compressor would definitely not be an overkill( I am going to use it duing overclocking). plus i am repurposing a fridge compressor. i think i might need knowledge of welding and coupling for the pipes, and some knowledge of thermodynamics and the physical properties of gasses. My major concerns are what dangers and precautions should i be aware of.

Best way to keep a small room with a hot gaming PC cool?
I have a pretty small room with a computer I game/stream on and that obviously that expels heat extremely fast. Is there anything I could try building/doing short of using my fans or opening my windows/door which aren't always an option for me?
I am also In the process of building a new rig so any suggestions on what to include on that to minimize heat expelling would also be appreciated.
