You will not be using everything all at the same time. So I would look at the nameplate Full Load Amps of your largest load, probably the table saw, plus any other things that might be running at the same time, such as the dust collector, lights and if the compressor is on a demand pressure switch, add that too because it might come one without you turning it on. Then add another 25% for good measure

Screen blank, does not boot

You dont give too much detail of exactly what is going on when you switch the RPi on. The LED lights should be doing something, as stated by Krzysztof Adamski in the comments.Please go through the following link, this should tell you exactly what's wrong with the RPi. If you've gone through everything on that link and it still does not work. Then the RPi itself is faulty and can be returned for another one

Are you familiar with CZIC Automotive LED? How about CZIC LED Fog Lamp?

Fog Light LED Bulbs Increase the light output, safety and style of your fog lights with light emitting diode bulbs from CZIC LED. LEDs match the size and shape of your vehicle's original equipment and install easily without modification. Sealed, moisture-proof casings are extremely resistant to vibration, and because substrate in the bulb does not get consumed during use, it will typically last a lifetime once installed on your vehicle. Available in multiple colors.

What's wrong with my IR sensor

The answer I've accepted is the correct answer, but I wanted to add this extra bit for completeness. I reworked my code to use non-blocking delays for the IR LED so the sensor actually gets a chance to see it before it stops transmitting and it works! Range is quite a bit shorter than the 'lucky dip' sensor ( 2cm).Every time I use delay() (or delayMicroseconds()) I find a new reason not to!.

How scientifically accurate is the TV series The Expanse?

There was serious effort to get away from the silly Star Wars Lucas-obsession with WWI fighter planes banking against nonexistent air. The ship maneuvers turned to use rocketry in a generally plausible way. Likewise no ray blasters but kinetic weapons. Credible. A bit hard to believe that a civilization accessing so much in the way of asteroidal riches, with robotics, would have a teeming underclass of grinding poverty, but it drove the plot

Using connectors rated for 250-400V with 5V

Connectors are typically rated with a maximum voltage, meaning every voltage up to the rated one is okay. For you that means the 12V and 5V are totally fine to be used on a 250V connector. You still need to make sure you don't overload them with the current you are going to use, e.

g. a 5A/250V connector should not exceed 5A, even if you use it only with 5V

Do betta fish like LED lights?

That depends on what you mean by LED lights

If you mean a LED bar with white LED's, then yes, that is a proper aquarium light

But if you mean those colorful LED's with red, green, purple, yellow, blue, ...., then no, especially not when the lights change color all the time!

If you have a light for your betta, make sure to have floating plants because they don't like direct light

Looking for good headset for gaming/youtube/movies

I used to be a fan of Bose until a friend told me about Sennheiser. They started out making monitors (headphones) for the music industry geared toward musicians and then branched out.I have these exact headphones and they sound phenomenal and they fit perfectly. (Sennheiser CX200. )Not only does it fit all your specifications, but it has a huge 2 year warranty (one of the reasons I forgot how to spell Bose)

Led lights for live events

LED modules often require an external driver circuit to limit the current. This can be as simple as a resistor or as complicated as a current limited buck/boost convertor.LEDs will give off light even when not driven to their power rating. Underdriving them will actually increase their overall lifetime.However marketing departments will often round up (significantly so) the power of LED modules because actual higher power modules are more expensive

Keeping a PIR on all the time

A PIR has a pyro-electric sensor, filter, and Fresnel lens that is designed to detect the IR from a human body, which has a wavelength of 5um to 10um. A IR LED usually emits in the region of 800nm to 900nm. So, a PIR will usually not detect the IR from a IR LED. You can easily prove this by aiming your TV remote at the PIR - it should not trigger it

adding a push button on LED string lights

yes, that button will work with those lamps.Just cut one of the wires between the batteries and the LEDs and connect each end end to a different terminal on the button. soldering is probably the best way to make that connection.

You will nee noth switches to be on at the same to light the LEDs, so maybe turn the battery box switch on and then glue it so that it does not turn off accidentally

Problem with delay before LED turns on

The obvious answer is to use a small microcontroller. That will be a lot fewer parts than trying to do this in analog. You can then also arbitrarily program the delays. You only need a micro with 4 output pins and preferably a internal oscillator to make the circuit simple. I'd use one of the PIC 12F parts. These come in 8 pin packages and have up to 5 output pins, which is one more than you need

Modify my old (1978) car's existing dash light dimmer (10 ohm Rheostat) to control LED replacement globes

You could use a cheap microcontroller (e.g. ATTiny85 or similar) to measure the voltage output of the existing circuit using its analog to digital converter (using a voltage divider to reduce the input voltage to a range the microcontroller will tolerate) and use that to set the duty cycle of a PWM (which the microcontroller also has). Then just use a transistor or mosfet to drive your LEDs from the PWM output

Dimmable LED lights flashing on full power

The flashing sounds like it may be the result of some capacitance that is getting charged and discharged at full voltage. AC transformers have capacitors in them in order to smooth out the waveform (process called rectification). The dim setting might be working at a lower voltage and the power supply struggles to provide the power at full 24VDC. Try measuring the voltage on the power supply, you may have gotten a defective unit

What features to consider when selecting a ring flash?

If you want a true ring flash, depending on your kind of macrophotography:If you do very close shots, there are also circular LED lights that aren't technically flashes but are much less expensive and can do the job (Canon has a macro lens where such LED are built-in).Being able to use only one half of the device for side lighting is a useful feature (full ring flash tends to produce flat, shadow-less images)

Full Spectrum LED (400nm to 840nm) vs Grow Light LED (REDBLUE)

I got a ready-made setup of 7500K LED light with 6 blue LEDs.

It's giving very good results, but the only thing is blue light favours algae growth. That's the only factor which was killing my tank's beauty. If we increase the CO2 in tank (go for pressurized), it will easily solve the algae problem of the tank. Addition of Flourish Excel will also boost the performance.Note: This answer is from my own experience.

How is the future of CFL and LED Lights business?

I would expect so as the use of low power requirement bulbs gets known for cheaper electricity bills and longer battery life with little fade. I am very impressed by my household and hand held lighting devices. What is really needed is some way of getting a low power supply into houses for lighting circuits, without a transformer. The best I can do at present is running them off a trickle charged car battery.

What are some safe investments should Bernie Sanders continue to lead in the Democratic race, aside from the obvious like renewable energy?

In the long run, the economy will do much better if Sanders or another progressive Democrat gains office. Contemporary history tells us that the economy always does better with Democrats in the White House.Passing substantial health care reform, for instance, will ultimately benefit the economy by relieving companies of the substantial payroll burden of providing full-time employees with insurance. This will allow us to compete with European nations which have done so for a long time

coax switches for HF

RF-specific parts aren't really required at HF. The physical dimensions of ordinary switches and relays are so small relative to the wavelengths involved that as long as you make a reasonable attempt to keep the leads short, it will work just fine.Specific product recommendations are off topic, but there's really no need. Just be mindful of current and voltage ratings (which won't be difficult for powers up to 100W) and you're set

Interactive Single Color LED Matrix

You can get ADCs that have multiple inputs and speak SPI, eg: (randomly selected example, in general Linear are good for this sort of IC)So, build a matrix of phototransistors. Put the ADC across the columns and energise a row. Read off a set of values.

(This solution may require investigating what the minimum response and sample time of the phototransistors is)

555 timer oscillator schematic question

A simulation in LTSpice suggests that the circuit will "freeze" (will not alternate) with the prescribed 20k resistor and 220uF capacitor. I recommend switching to a 10k resistor and a 440uF capacitor instead.As for the rest of the circuit, I suggest bumping the LED current limiting resistors to around 480 ohms. 150 ohms will allow upwards of 48mA through the LEDs (depending on their forward voltage drop) which will most likely destroy them. Keep it closer to 10-15mA
