Picked up a new akko 3068 keyboard mx master 3 and new key cap set for my ducky one two skyline.

Deffinitly agree. The software on the scope is absolutely one of the most important things when it comes to usability. Realy one of the major reasons i picked up an r&s rtb2004 a few months back. The software is just so far ahead in terms of features than other companies at even similar price points.

Main reason I like to recommend the sds1202x is the 200mhz bandwidth Which is the main selling point over the 1054z to me. If you need the extra channels the 1054z is the way to go though you can run out of bandwidth pretty quickly at only 50 MHz. Really depends on the end use.

i would do yourself a favor and save up to get something like the silent SDS1202X-E as it represents an amazing value for a 2 channel 200mhz scope. If you really need somthing now i would go for a siglent sds1052dl. I would avoid the hantek's, owon's, and uni-t's as they really have pretty horrible front ends that make getting accurate measurements quite difficult. Saving for a bit and getting a better scope now will end up saving you money down the line.

if your psu is too weak your pc would crash and shut off. A psu will have zero effect on fps.

when it comes to consumer electronics like parts used in a normal pc, damage from static discharge is incredibly rare. I would not worry too much about it. Just touch something that is grounded every now and then. As someone that works with electronics and bare ic's on a daily basis, iv only seen a few cases, and those all where during electrical safety testing.

Got a cheap h87 itx motherboard and an itx bracket for my case to use with my old 4670k and ram. Just waiting on the revolt x power supply to get everything going simultaneously.

What you probably want is an sdr. RTL-SDR's are prety cheap anD cover from 50mhz-1.7ghz. You can use an upconverter along with them to listen to all the HF ham bands. If you want a pretty good cheap option the nooelec nesdr smart and the hamitup down converter are pretty good. Here's a kit that would do prety much everything you want, thou i would recommend using better antennas for vhf and uhf. https://www.amazon.com/NooElec-NESDR-Smart-HF-Bundle/dp/B0747PX3NZ/ref=sr_1_6?crid=2E6RU52ZC2GWE&keywords=nesdr+smart&qid=1579307085&sprefix=nesdr+sma%2Caps%2C203&sr=8-6 Here's a good guide for getting started with pretty much any rtl2832 based sdr https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/ I would also recommend using sdr# as its pretty intuitive to use and has a ton of compatibility. Its at least my preferred scanning software. -
A bit late because I already built it, but I got parts to put together a new system. 3900x cooled by a nh-d15 in a msi x570 unify with 32gb of Kingston hyper x 3200mhz ddr4 and a sabrent rocket pci 4 ssd in a phanteks evolve x. Gpu, power supply, and other storage was reused from the previous build.

Picked up these small Doppler radar modules
-
Its been pretty awesome following the progress and recent launch of fossasat-1. Congrats on a successful project! I need to try and see if i can pic up a pass with some of my rf equipment.

No, mainland Africa is not an island, neither is Australia by definition. Trying to bend and interpret definitions to further your argument really doesn't help your case. This is literally elementary school stuff here. Neither Africa, nor Australia are islands. Case closed.

No real issue as long as the separate rails are the same voltage. Its pretty common practice it quite a few designs. You cant combine rails of different voltages however as the lower voltage rails will sink current from the higher voltage rails. I have built quite a few supplies not all that different than the one pictured above and its a pretty decent way of getting decent current at many voltages for not much money.

You would be surprised how many companies use 3d printing for FAR more than just prototyping. Saying it is only good for prototyping is just plain wrong. In many cases 3d printing can be far superior in both strength and cost.

so they "invented" a lenticular lens? Looks like you can sell anything to the military if you put quantum somewhere in the overview.

Threw together a little headphone amplifier to try out osh parks new after dark option that gives you a 2 layer board with black fr4 and a clear soldermask. Looks pretty sweet if you ask me. Design is based on a tpa6120 so it should perform decently once i get the parts in. Might try my hand at a full amp/dac if it works out well.

New oscilloscope. It's a Rhode & Schwarz rtb2004 with the fully loaded com-4 package. It's just amazing

Wavelength is a function of propagation velocity, and frequency. All you need to do to get wavelength(λ) is divide the speed of the medium you want to calculate for which is the speed of light in this case, by frequency in HZ. An example in your case solving for the wavelength of 145mhz would be λ=299792458 m,s / 145000000 HZ where λ tuns out to be approximately 2 meters. That band is also commonly referred to as the "2 meter band" because of its wavelength. You don't actually need to have a full wavelength antenna though as divisions of the desired wavelengths are still resonant at 1/2 and 1/4 wavelengths. There are other tricks you can play to get even small antennas such, but i wont get into too much detail.

I don't even know why they would be advertising that they use components using ethically sourced metals. Pretty much any pcb fab/ assembly house worth their salt will already have a conflict mineral policy. This kind of thing has already been widely adopted in industry so far. The only place this is currently an issue still is with bottom dollar grey market and counterfeit electronics. Its nothing like it was 20 years ago.

The Focal's are definitely a good recommendation. I have a pair of the chorus 706's and frankly for the price im not sure there is much better. And they are amazingly good for near field listening.

Do you prefer electronic or hydraulic vehicle steering
bob345 replied to Nine Tailed Fox's topic in Off Topic
Realy depends on the car. Ive driven cars with great hydraulic and great electric steering racks as well as terrible versions of both. I do think modern electric steering racks are far Superior to hydraulic power steering though. Good electric racks give so much more feedback because of how fast they can react. A lot of people are surprised when they hear that new wrx's and brz's/86's all use electric power steering because they offer pretty amazing steering feel. -
Just put together my new chair. It's a dx racer iron series. WAY better than my previous chair which was pretty much on the verge of falling apart.
-
Nice looking layout! Ive been wanting to do something like this for a while too. What EDA are you using? eagle?
-
Heres my current setup. Main speakers are some focal 706's which are pretty fantastic for either near field or normal setups. Amp( not shown) is a smsl sa-50 with a schitt valhalla 2 being used as a preamp/headphone amp as well as a schitt modi 3 DAC. Headphones I now use are senheiser hd6xx's

I mean, TECHNICALLY you could pass a digital signal over a 3.5mm jack that carries 5.1 audio, but there is no standard i know of in existence that does that. If you are using headphones, you can approximate 5.1 surround sound, but you really never can get true 5.1 surround sound from only two speakers in a room. Its even there in the name. 5 being for 5 separate speakers (front left, front center, front right, rear left, and rear right) and .1 specifying a single sub-woofer.
