Machining and Microwave/mmWave Radio experiments. Spy devices. 3D printed antennas.
I design and make parts for experimental radio systems, scientific equipment and talk about unusual and cutting-edge topics related to high frequency electronics, antenna systems, waveguides, combiners, cavities, filters, digital comms, CAD, E-M simulation tools and microwave circuit design.
I hold a licence which lets me transmit between 136 kHz and 1 THz. I carry out experiments including RF, plasma, high voltage, hard vacuum, precision machining, metrology and electrochemistry. I've worked with commercial sponsors to produce collaborative vids on specific products and services within my subject area and welcome business enquiries. I've also appeared on BBC2 TV with Prof Hannah Fry, demonstrating my replica of the Great Seal Bug spying device.

Satellite Dish Mount Experiment | Laser Engraving
zhlédnutí 8KPřed 5 měsíci
Satellite and microwave dish mounts often don't allow smooth and precise azimuth rotation. This is my attempt to machine sturdy and precise rotary microwave and satellite antenna dish mount with taper roller bearings, accurate degree scale and pointer, using a desktop laser engraver, multi-color 3D printer and a manual lathe and mill. This video covers the machining, fixture-making and testing ...

Creality's new 40W Falcon2 laser engraver is a brilliant tool for folks like me and you who don't want to get involved in the geeky details. It feels like a complete product, not a half-finished Kickstarter project like some lasers. It's compact, light and solidly engineered. Compared with a CO2 , it's lower cost, portable and doesn't need water cooling. I was about to buy one for my business w...
Can I Machine Precision Ovals with a Shop-Made Lathe Dovetail Fixture?

Making precision oval iris plates without CNC machining is HARD. Especially if you don't have a good precision boring head for your mill. Here's how you can make a ludicrously over-engineered fixture for manual lathes to make arbitrary-sized oval iris plates for very high-performance Microwave Waveguide Antennas. The shape I'm making isn't strictly a mathematical oval, it's a STADIUM, with two ...

I've never cut a gear before, so it's time I tried! How many times can I mess up? Join me in my scary first attempt at machining a tiny pinion in my home shop. A friend asked if I could make a replacement for a split plastic gear from an antenna rotator. Watch me try to understand the jargon and work stuff out.

Simple Low-Cost Lathe Tailstock Rotary Collet Chuck

You too can machine a very simple, low-cost rotary tailstock chuck for your lathe with this OneSimpleTrick(tm). Spoiler alert, there's no trick, this device really IS simple to make. Holding small diameter workpieces in a lathe often needs a tailstock-mounted rotating chuck. They are a lot of work to make and are not exactly cheap to buy. If you already have a rotating tailstock centre, this is...

for your chamfer tool order yourself another of those tools cut both shanks and mount them back 2 back and you got 1 holder being able to do both.
@@cornnatron3030 Good solution! I have a spare that's mounted the other way round, so I can save a holder. Nice, thanks for the suggestion
I'd heard the story of the bug long ago, but the technical specs were nice to hear about.
Very verbose
@@MarkBesaans That was after cutting around 60% of the story.
Its been months. I hope everything is ok
Well, there was The Accident. I was using a pressure washer to clean out a blockage in my septic tank connection from the house drains. I was using boiling water and drain cleaner to help dissolve a mini-fatberg. Somehow I got both ankles tied together with the power washer hose, while I was moving rather rapidly, and fell forward as an appreciable fraction of the speed of light. I missed the open septic tank hole, which might have ended up with a fatal result, but I fell on to a low brick wall with a sharp edge, landing on my right forearm. Unfortunately, I was carrying half a gallon of freshly-boiled water, and it all spilled out on to the back of my other hand. My ribs hit the pressure washer, and I damaged my ankle and knee as well. Luckily I was only ten paces from a cold water tap, so I hopped over to it and ran icy water on the burn for ten minutes. Then I realised I had no cellphone coverage, and no landline phone, none of the neighbours were around and Rose was away. I was starting to go into shock, so made the decision to hop to the car on my good leg, clambered in and drove with my good left foot on the throttle and brake, and my rather damaged right hand to steer. Car is automatic, so it wasn't too hard about from using the wrong foot. I got to the local hospital and was seen within three minutes. They fixed me up, cut away the burnt skin, took X-rays and applied fancy dressings. No broken bones but my arm was black from the wrist to above the elbow, with a gigantic haematoma like half a melon on it. I still can't type properly, nor use a mouse, and my right shoulder is messed up, I can't hold a screwdriver or pen very well, and my grip strength is poor. Left hand burn took AGES to help up, but I had excellent support from the wound management and specialist burns folks, and now it's hard to tell it was ever scalded. That's HALF of the reason I've been absent. The OTHER bit is a lot more exciting...
Now for the GOOD news. I've been commissioned by the same TV series that I did the Great Seal Bug for. This time, the task is hugely more complex. I have to make a replica of a piece of historical equipment (well, two actually) from 100 years ago. I am working 80 hours a week on the project. I've already machined over 240 separate parts of the mechanism, and in two weeks I have to have it all working and go to a secret location to meet up with the presenter and crew to explain and demonstrate The Machine. I am at least ten days behind schedule, but that's normal for me. I need that impending panic to get my ADHD-ridden brain to go into hyperfocus and get stuff done. I can't talk about the details until the programme airs some time later in the year, but I've been recording what I can so I can make a series of vids about it after the release date. After the studio session at the beginning of September, I'll be able to get back to making videos. I have about 60 hours of project work on video, with a lot of material about getting to grips with the new CNC machine.
I should do a few community posts I guess, but every waking hour is spent doing CAD or experimenting or machining stuff for Project Narwhal, and I'm seriously short of sleep. This is all written using the rather splendid voice dictation service in Windows 11 so I don't need to type other than edit a few words. Marvellous thing, technology.
very interesting and insightfull.
Looks like the Gyroid infill pattern from the Cura slicer!
@@bluegizmo1983 Indeed, but with spatially-varying wall thickness. Gyroid lattices guarantee no internal voids and by varying the equation in all three coordinates, you can achieve a varying refractive index across the bulk of the lens.
Yeah, makes sense!
It's fantastic but how dose the listing device work
External 1 GHz radio signal is beamed at the device. Sound waves vibrate the metal foil membrane like in a condenser microphone. That changes the resonant frequency of the microwave cavity. As the tuning moves towards and away from the external signal, the response gets stronger and weaker, thousands of times per second. The re-radiated signal is mixed with a sample of the illuminating transmission and the receiver uses the homodyne principle to recover the audio. Mathematically, the modulation produces sine and cosine components with a frequency of 1 GHz plus the audio frequency and 1 GHz minus the audio frequency. Multiplying those by a sample of the 1 GHz alone results in products back in the audio range. Similar to a direct conversion receiver, but that has its own local oscillator. The clever trick is to use the original signal as the local oscillator, so you cancel out any drift and most of the frequency instability caused by microphonics in the transmitter oscillator. Have a look at czcams.com/video/1iG6bOpgYes/video.htmlsi=CplRRXdapmxbYuaa&t=48 where Davis Ricketts explains the homodyne concept. The start of the video covers the mathematics
13:45 the USSR was not limited to the technological knowledge of their mother country on 1945, as thwy had thousands of engineers of Telefunken AEG , and Siemens in their Gulags who did manage to do 3GHz (MegaMegaCycles for our American friends) in so called Acorn shaped Vacuum tubes (Thermionic valves)
