Secret Patreon stream

Here's the link to the mid-week stream happening this week:-

Exploring an ultrasonic pest repeller

This unit appears to be real, in that it does put out a swept ultrasonic sound.

https://youtu.be/_fEn_zUbiXQ

Whether it actually has an effect seems to be considered controversial.

Experimental pinball-style illuminated inserts.

This actually worked better than expected.  It does require a 3D printer, but the inserts are so fast to print that you may be able to bribe a friend to make you some.

https://youtu.be/SyjoILhsWBg

It's basically a couple of customisable insert designs that can be recessed into wood so you have points of light that are flush with the surface like pinball score and gameplay indicators.

Oh yeah, that's better.....

I contacted Sure and they said they couldn't see the router from their end.  They suggested a full router reset, and it fixed the problem.

I was kinda hoping for a higher upload speed than 20Mbit, but it's already made a huge difference to the video upload time.

Troubleshooting an infrared beam race timer

This is an RF connected system for starting and stopping a race or obstacle course timer.

https://www.youtube.com/watch?v=wElurSAW_nY

The construction reflects the fact that this is a very specialist device hand-made in small volumes.  It came well packed in a pelican case.

I did subsequently neutralise the electrolyte on the contacts with vinegar before washing them and cleaning the met...

LED fishing lure light

Not being much of a fisherman I can't tell you how effective an underwater light is at attracting fish at night.

https://www.youtube.com/watch?v=dDKDt8N_hnQ

Let me know if this technique does actually work.

At the very least it must be visually quite attractive with the coloured glow under the water, and fish roaming around it.

AvE swing press versus Poundland lithium cell

This took longer than expected to get going.

https://youtu.be/EgtKwxzgggg

But it did - and that's the main thing.

Electrosurgery pen

Stuff like this makes me feel a bit squeamish.  This is a surgeons pen that uses RF energy to cut and simultaneously seal flesh so that surgery can be performed with minimal blood invasion.

https://youtu.be/cqFduRalCnQ

This video is just the pen and not the RF power supply.  I'd guess the RF energy source is likely to be like a scaled up cold cathode power supply.

As promised - depotting the biggest one

Yeah, I know.  Another ionic video - but I'll be back to other non-ionic stuff in the next one.

https://youtu.be/rt6DEjCuKFU

I think this is eBay biggest ion module, unless you've seen a bigger one?

Mid-week live stream reminder

So bad it's amazing

This is definitely in the category of well made junk.  It has so many design flaws and technical issues that I think it may be a very bad copy of another product.

https://www.youtube.com/watch?v=0o0emBQfeL0

I'm not going to let that resetting issue beat me.  It's like a puzzle that must be solved.  Although I have a feeling that it may be due to bad setting of the microcontrollers re...

The new fibre connection

By request, a picture of the unexpectedly small incoming fibre optic unit.

The black and white cable is the outer black reinforced overhead tube with the white inner fibre sleeve.  The excess/spare fibre is figure-eighted at the back of the unit.

The black cable is a plug-in power supply.

The red cable is a data cable.

The stuff on the left is my old ADSL line.

Another front plate option

Here's the new front plate with different words and correct spelling.  So you don't mix them up, the PCBs are as follows:-

ozone1 is the main needle panel.

ozone2 is the original misspelt atmoshperic invigorator front.

ozone3 is the new molecular disruptor front.

Russian Nuclear Corporation - original

I've never tried posting direct links to zip files here, so here goes.

http://www.bigclive.com/ozone1.zip

http://www.bigclive.com/ozone2.zip

Those two files can be dumped on the "upload gerber" box at your preferred PCB maker.

I didn't combine them into a single board for smooth edges and rounded corners (no mouse bites o...

Quiet mid-week Patreon stream link

The first stream going out on fibre optic.

https://youtu.be/yZgoc0axP_I

No download speed improvement from the old copper ADSL, but the 20Mbps upload is a huge improvement.

Project with PCB files and optional 3D print

A safer version of the dangleberry light, with PCB to accommodate the resistors and a convenient USB connector.

https://www.youtube.com/watch?v=NyBVBzIefd4

This project also has a 3D printable case, but it can also be sleeved with heat shrink sleeve, wrapped with tape or just put in a standard box.

Fibre (fiber) going in

The fibre is now on the wall and the associated equipment will be installed tomorrow if all goes to plan.

Not sure what effect that will have on streams yet, but it should hopefully make uploading videos a lot faster.

New project PCBs

Let me know what you think of this idea, and if I should put the files up for download.

https://www.youtube.com/watch?v=IoN_EYtSuio

I may also change the text to something more sinister for extra drama, like "molecular disruptor".

Irish Sea stream

Here's the link to this Saturday's stream:-

Fixing a faulty PSU

You don't really need to know a lot about switch mode power supplies to repair most faults.

The components most stressed in these power supplies are the output diode and capacitor, as they both deal with fairly high current at high frequency, and that results in much hotter running than old-skool power supplies that only had to deal with 100/120Hz ripple current.

https://www.youtube.com/watch?v=MZDX-1A...

Inflatable solar light (clone) with VERY used battery

A cheap clone of a fashionable LuminAID solar light that is shipped as a very compact package and then inflated to create the full diffuser.

https://www.youtube.com/watch?v=r1dIbZ6mtGM

This version is the cost-cutting minimalist version.  It actually earns extra points for using a salvaged battery.

Commercial fishing boat work light

Nice construction, but completely unrepairable due to the way the glass has been sealed in.

https://youtu.be/9cFt66hf5GY

On a plus note, the aggressive sealing means that this light has survived years on a commercial fishing boat on the storm-ravaged Irish Sea.

Mini USB swamp cooler with "UVC sterilization"

As the thumbnail already alludes, the UVC LEDs aren't quite what they seem.

https://www.youtube.com/watch?v=iSTZIzJT2o8

It does work as an air cooler/humidifier though, and would make a good base for fan based projects.

Mid week Patreon stream reminder

Remember there's a Patreon live stream (with wine) happening within an hour of me posting this.

Just about to release the ozone video

I'm releasing the "great big ozone video" slightly earlier than usual just to see how long it takes for the anti-ozone brigade to appear in the comments (without actually watching the video first.)

I de-potted another high voltage module

While scouring aliexpress for weird modules I found these, and since they looked different to normal ion modules I bought a couple and de-potted one to reverse engineer the circuitry.

https://www.youtube.com/watch?v=ERTaantiY6c

One of the most remarkable things about this high voltage module is that it only uses about 17mA at 12V.

I did subsequently de-pot the other unit with loads of emitter...
