Hey, /diy/, first-time poster here.
I have been getting very interested in DIY synthesis lately and wish to build a basic synthesizer. Nothing special (yet), a basic momentary switch and something to generate the tone. I had been using a 555 VCO but want to do more, such as produce different types of waves (sine, square) and add a filter. Any resources would be greatly appreciated.
Image is somewhat related.
Please help me /DIY/, you're my only hope!

So I'm a dog groomer. I love the work. I'm good at it. I want to keep doing it. What I don't love? Shitty schedules, managers who refuse to charge the right dollar amount for the amount of work that I've done (like spending an hour brushing out a matted dog - that's an hours worth of work I didn't get paid for!), and customers getting upset because somebody forgot to relay important information from me to them.
I'd like to get into mobile grooming. Most of the mobilers I've talked to really love it, and the potential earnings are to die for. If I do this shit right I could be looking at a 100K+ salary after taxes.
The picture on the right is what an actual conversion company will do. They charge about 35Kand up to do a conversion if you supply a van, or else they can buy a van for you, and sell it as a bundle deal. There is no way I can afford a down payment for something like that on my current salary.
I've asked around a few RV and autobody places, but nobody knows what the hell I'm talking about. So, here I am. How do I go about doing this myself?

I'd like to go in the crawl space in my house, unfortunately, I'm afraid of spiders (yes I know, stupid). The reason I need to go in the crawl space is because I'm planning on installing a sprinkler system and I believe the water main is in the crawl space, so I'll need to splice it from there in order to get a proper system installed. I'd also like to go under and put in a cat5e network to some rooms.
Do you guys have any ideas on what might comfort a coward like me in going down under? (I've heard there's coveralls that help, a stick to clear cobwebs)

Hello /diy/, first poster trying his luck here. Sorry if this comes off as rude.
I'm looking for ideas regarding a project I need for school. Don't worry, I don't want /diy/ to do all the research for me or anything like that, I'm just looking for ideas. All the design comes from my part. If the end result gathers enough interest I'll can post the PCB schematic(s) and a guide for it when it's done.
It's in the area of electronics. The project needs to employ semiconductors (diodes and transistors, specifically) to do whatever I want, as long as it has some degree of complexity. Sounds easy enough, but I want to make something useful. Something I can use from time to time and be proud of how well it works.
I was thinking of making a power-supply unit for guitar pedals. The problem with it is that it only needs diodes (a diode bridge and a Zener diode for regulation). I can't think of any useful addons using transistors for this.
I also have a micro-controller development platform I can use (32-bit, 48 MHz, 256 KB flash, 32 KB SRAM, segment LCD, USB 2.0 capable), but I'm still not capable if using it in USB applications. It doesn't have an OS like the Raspberry.
Any suggestions for the power-supply? Other good projects?
Thanks in advance.

i'm mid way through an attempt to wire spotlights into my car. i want to use the stock switches, but they are not what you would call a simple thing to understand or use. i mocked the switch up in LTSpice, and have added, in MS paint, approximately what i would like it to do. (pic attached)
Basically, it's a momentary switch that shares a common ground with an indicator LED and a backlight LED. i want that momentary switch to toggle a on on/off switch, which is then fed to the 12v automotive relay AND back to the indicator light.

I don't really know if I should be posting this here, but I am looking to a diy solution to problem.
I'm just back from Japan, and while there got some poster books containing my favourite anime characters. I'd really like to preserve them, but they're just little A4 posters, and far from frame-worthy.
What might be the best way to go about keeping them preserved, but still able to be displayed?
