Moving to a new lab (Part 2) New basement lab and workshop tour

Here you get a short glimpse of the new space for lab and work shop.

This is part 2 in a series of videos on moving out, moving in and setting up the new lab / work shop.

I am moving out of the apartment and into our own house, which has a room dedicated to the laboratory and a work shop for rough work.

Taxi Radio Basestation teardown – UHF/VHF Storno radio

This is a teardown of a complete Taxi computer and radio base station system. The Taxi car computer and connection box is used for location tracking, taxation, passenger detection and correct price calculation. All done in order to make sure that correct taxes are paid to the government but also to ensure that fair prices are billed to the customers.

The radio base station backbone of the systems are rather old and works in the 150 MHz range for both transmitting and receiving.

The two amplifiers are a Storno CQF612 and a Storno CQF9112, there is plenty of historic data to find on these using google if it is of further interest to the reader.

How to build a Tesla coil. Design, theory and compromises!

A live broadcast that I did on Sunday, February 4, 2018 with focus on designing Tesla coils with special focus on the DRSSTC topology.

Questions about the Tesla coil theory and design tools can be asked during the broadcast and I will answer them to my best knowledge 🙂

Computer scrap gold money WITHOUT chemicals or mechanical processing

In this video I show how you can still make money on scrap computer parts without refining the parts yourself, so there is no use of chemicals, no tedious work in crushing and grounding parts, no burning and melting. Just a quick way of getting it exported with correct paperwork and get the money directly to your bank account.

Selling whole parts will ofcourse yield a lower price then processing it all yourself, but equipment, chemicals, refining, work hours, wear and tear on your stuff is all important factors to count into the equation, last but certainly not least, take care of your own health! Chemicals and fine dust from crushing electronics is not good for your body if you fail to protect it correctly.

This is the part 1 of 2 video and the second video will be about the process after the packet has been sent, comparison with my estimate and what is really paid out. I expect to have part 2 ready in a week or so.

How I came to build a 4 meter spark generating Tesla coil, a technical story from 2008 to 2016.

Here is the recording of the live stream I did on 2018 January 31, Wednesday at 2000 CET, I performed a live stream on youtube to talk about how I started building Tesla coils, the journey that went on for 8 years which ended with me having a 3 meter tall Tesla coil that can do 4 meter sparks. Questions was asked and answered along the session.

FPS1000HD high speed camera unboxing and first impressions

I ordered the FPS1000 platinum back in April 2015 on kickstarters backerkit site, then in March decided to upgrade to the platinum double.

Fast forward 1½ years and the projects stalls, a new kickstarter for the FPS1000HD was started (which was a new name for the platinum double), it was offered to get a refund or camera from the original kickstarter, but only when time and money in the company allowed for it. I chose to get the camera and now I have it!

First impressions on a camera that I can not yet turn on.
– Looks and feels good
– Stock lens seems a little too cheap, but that is just from looking at it, no idea about actual performance
– The back cover plastic part around the LCD has sharp edges all around it, sharp enough to give a cut in the finger :(
– The screws mounting the fans on the front is not aligned with the surface of the front plate, so they go above the surface and can get stuck in things since its concave heads
– Manual is missing more specific information, especially on what power adapter to use and what kind of power plug it actually has!
– There really should have been a power supply with it, it is a expensive product and the hassle with finding a suitable one already set me back one power supply not usable since I just had to guess on the jack size from pictures.

 

Above is a new video with a explanation of the setup I have used with the camera and what my first impressions are so far.

I have used the stock 35mm lens a couple of times, but most of the time I find it much better to use my huge Ernitec F1.8 16-160mm lens, it does however has it limits as it can not focus below 50 mm, but this is not really a practical issue as it is used for gaining a lot of range to whatever it is I am filming, this is nice if its explosions or electrical discharges.

Battery life is around 1 hour as expected, get a fast charger! USB chargers are simply too slow for 2500mA batteries.

Reading the manual is a must (I never thought I should say that) as the user interface is not intuitive when it comes to the advanced commands.

The PC software is simple but does its job very well, after I got a USB3 cable there will be no more saving data to SD card unless I am forced to do that, the transfer speed of the USB3 is about 100 times greater!

I just need 3 things. Light, light and more light

Youtube removes monetization for all small channels!

I hope that everyone will watch this video as the changes youtube is making has a much larger impact on the electronics / high voltage community than just my own channel.

I hope you will help me spread the word of my channel to your friends, colleagues, study buddies and so on.

In the next 30 days I have to gain 200 subscribers and 1500 watch hours in order to stay in the youtube partner program where I can make a little revenue on my videos. If I am not getting the money, youtube is keeping it for themself for the future.

Help the small channels and let me know if you have a channel that need help by being just as close to the goal as I am 🙂
