There is zero shame in buying preassembled boards, modules, jacks with presoldered wires attached or anything like that. Or kits with all the surface mount work done for you.

There's a lot of great options for constructing things from modules and cable harnesses out there these days, and if it's the easiest way to build the project you're envisioning, go for it!

This is especially true if you are unable to solder or do fine detail work well!

At the end of the day, you still made something, and it's yours.

(Also, if you think I solder all of my own connectors and surface mount stuff, you'd be wrong)

Yes, this is a subtoot based on DMs and conversations that have happened over the past few months where folks have commented to me that they don't feel like they're doing real hardware hacking because they're not designing their own PCBs or soldering every wire or something.

Just go out there and make things!

@recursive @abraxas3d @Stormgren There are also hacker spaces with mills and CNC gear, and people there who may happy to do machining for others.

@Stormgren totally agreed, and there is simply not enough time for a normal person to do everything from scratch.

@Stormgren @recursive @abraxas3d This is where I'm at with uwaves. I built a 10 GHz amp from a kit a while back and that was a good learning experience at the next level down. One barrier is having the right lab gear for hacking on uwave circuits. It's a significant investment in older tech (or very expensive new tech), and gaining specialized knowledge to use it. Slowly but surely...

@adamjsy Actually that seems like a reasonable price. I'm seeing $140-$400 for name brands.

Troubleshooting a Tek spectrum analyzer PSU. Gonna need a bigger boat. I mean, an ESR meter.
Any recommendations on a budget ESR meter? 🤔

A new batch of Linux Security Summit stickers has arrived! These will be distributed at upcoming conferences, starting with LSS-EU in a few weeks. There's also now a "Europe" 🇪🇺 version of the sticker.

I read this while flying across the Pacific Ocean and can highly recommend. Mersini-Houghton has established, with a testable theory, how our universe arose from an energy landscape as one of many different universes, overturning millennia of entrenched thinking that our world is special.

There's a good video on this here but I definitely needed the book to understand the finer details.

It's interesting that the observed evidence for her theory is stronger than she indicates in the video -- she is incredibly humble!

@vathpela not that I know of. I think this can be run on a real quantum computer if I can figure out the right cloud magic.

Best meteor scatter rx so far: 1127 km. With just a dipole & preamp on 6m.

Definitely living in the future here -- using AI to write code for a quantum computer.

The local electronics store (Vetco) is an Aladdin's cave of test equipment at the moment.

It could be interpreted as "to avoid starting a new interaction, do not reply", so if you did not want a new interaction, you would in fact need to reply.

@appfrosch @searls It is confusing English, and can be interpreted as the opposite of what they are trying to say.
