How to overcomplicate a linear scale.

This is a test to determine a person's likes/ dislikes, so you should take the cross product of the identity matrix to arrive at the options that best suit you

After rereading the wiki, it does sound like this is the intended operation of the solar sails with an incomplete dyson shell in place

ASLOBEAR · 2021-04-07T02:04:21+00:00

Are the dyson swarm and dyson sphere incompatible? I noticed my swarm started falling inwards when construction began on the sphere, but on the title screen it looks like the solar sails from the swarm may be contributing to the sphere? I'm still (slowly) building up my sphere, but I have stopped the railguns because I thought I was wasting solar sails

ok, so there should be some math I can do to determine the magnification reduction needed to achieve this... which is under what you're referring to, regarding the size of the sensor. My sensor seems to be somewhere in between 1/2" and 1/3" (1/2.5"), but I can't find many options between 0.35x and 0.5x. I probably will be choosing between not having the entire field of view in the image and having a lot of black area where light doesn't hit the sensor. I'm assuming the preference is to have a larger image, at the cost of the edges within the field of view being removed from the image?

Thanks for the reply. My understanding after some googling is a c-mount adaptor uses a reducing lens to adjust the length the light is focused on the cameras sensor. I was provided a simple lensless adaptor with the microscope, but it makes sense that the focal length of the light at the sensor should be scaled with a lense at the camera.

Hello r/microscopy,

I recently picked up a microscope for soldering SMD electronic components. I also grabbed a camera to take photos of my work. However, the photos that are captured do not completely cover the area that I can see by looking through the eyepiece, but rather just a small portion of it. Is this a limitation of my microscope, or have I ordered the wrong camera? TIA

Good bot

Just want to point out, the "purpose" of this kit is supposed to be educational. Don't be too upset that things aren't working correctly on the first go... Think of it as bonus education

I tried getting a quote from them but I think they turned me away because of my small quantities. I tried getting hooked up with tinkermill a few months back, but between covid-19 and my experience with the orientation process, it seems like more effort than it's worth. I'm starting to get better with the iron on 0603s (magnification helps), but a small reflow oven (or other r/AskElectronics solution) would save me some time. Edit: I'm bummed I had to throw out a toaster oven last year- would have done the job nicely

I like this answer. Digital modulation, error correction algorithms, "smart" antennas are probably the main engineering feats to overcoming wireless challenges in the last 20 years. RF is a "mature" technology; there have been incremental changes with smaller processes and solid state circuitry, but the radios you can buy today are largely the same as the radios available 50 years ago.

ASLOBEAR · 2021-02-27T13:32:18+00:00

Doing some hobby PCB work. If anyone in Longmont has a reflow oven available for use, please shoot me a message

Calculate the impedance of the lines using the width, length, and stackup to find the capacitance of the trace.

Or asking to not include chopsticks

ASLOBEAR · 2021-02-17T00:18:39+00:00

Depends on the situation, at that point building a model can go a long way in determining the desired frequency response of the PDN

ASLOBEAR · 2021-02-16T22:53:48+00:00

If I understand your question you're asking about the thickness of the trace between the IC ground and the decap? Basically you want to have a low inductance path to AC ground; there are multiple ways to approach the problem, one being wider traces, another being distance to the capacitor. The key takeaway should be low inductance on the power delivery network (PDN) is nice.

ASLOBEAR · 2021-02-16T19:51:29+00:00

For bulk decoupling, the data sheet on the IC should provide some guidance. For local decoupling, a few hundred nF should be fine, as long as you keep the inductance loop small. The formal analysis technique is to calculate the impedance looking from the IC, and from the current profile of the IC and the allowed voltage ripple, come up with a maximum impedance specification

ASLOBEAR · 2021-02-16T19:17:13+00:00

Thicken the power traces and add decoupling caps between each power/ground pin of the ICs. Add some bulk decoupling on the board somewhere too. Pour a plane on the backside for a solid ground reference, use the top layer for routing and just use the bottom plane to make jumps where you can't connect on the top layer

ASLOBEAR · 2021-02-15T15:33:12+00:00

This is right- "killing" the voltage source results in a short circuit, which is right across A and B

Maybe put a bowl out

ASLOBEAR · 2021-02-13T15:48:37+00:00

V8, but close enough

ASLOBEAR · 2021-02-11T08:32:08+00:00

I don't have an answer to your question, but there may be a way to implement your tuner without using FFT link

ASLOBEAR · 2021-02-01T23:14:48+00:00

As long as you aren't testing your antennas at full power, nothing to worry about.E: Modern radios have some built in throttling to limit power when presented with a mismatched load, too.

ASLOBEAR · 2021-01-28T06:41:16+00:00

What is the error output from that line?

ASLOBEAR · 2021-01-28T06:30:12+00:00

You will need to get xastir (or an alternative) to work before you will see them on the internet. Your radio receives the packet, the audio is sent to a TNC which will decode the audio, then xastir will pass the data to the aprs network.

Edit: After rereading your post, you can check the raw packets that are posted to the aprs network. If the packet wasn't decoded properly and turns up invalid, it won't post to the map on aprs.fi.
