Evolution of a PSU Sparky Projects 2021-12-18 | Website: http://sparky-projects.co.ukForum: http://sparky-projects.proboards.comDiscord: discord.gg/yPHpW2jThis started of as a project to add modern power supplies to an old power supply, but things took a turnThe new power supply unts are listed as 'Rui Deng' in searches, the ones i have are DPS5005 USB50V input max, 5 amp with USBTransformers are 2x24v 160VA which is 6.6 amps full load with windings paralleled, bridge rectifiers are 10A.Apologies for the quick ending, i knew my mic battery was low, but it turned out to be my second camera which should have been a close up of the units while i was showing the interface software (PIP), unfortunately that's lost.

Computer Desk Rebuild Sparky Projects 2019-11-03 | So it got to the point where i could not get monitors to fit the frame i built over 4 years ago after a couple of monitors refused to work after a repair.The answer was to rebuild, this was helped largely due to an energy company rebate which meant i could complete the bottom row with all new monitors.The monitor stands are from 1home via Amazonamazon.co.uk/Monitor-Arms-Stands-1home-Accessories/s?rh=n%3A296770011%2Cp_4%3A1homeThe monitors are AOC, i have 2 x 19" and 2 x 22"amazon.co.uk/s?k=AOC&ref=nb_sb_noss

Useful (mystery) Tool Sparky Projects 2019-10-05 | This is a tool i've had for several years, occasionally it becomes very handy, only thing is, i don't know the name of it, or where you can get them.If you know these details, i will add them to these comments and pin your post.
A trip into history Sparky Projects 2019-06-14 | After my RCD (or gfci) tripped out sseveral times, i replaced it as i thought it had got weakened, so it's a good opportunity to take a look inside the old one.It works out that the test resistor is calculated to give a MAVIMUM offset current of 42mA (240 v/5600 ohms), but it's sensitivity can be adjusted down close to the 30mA.http://sparky-projects.co.ukpatreon.com/sparkyprojects

Exploring Bridges (Wheatstone) Sparky Projects 2019-04-29 | http://sparky-projects.co.ukpatreon.com/sparkyprojectsThe last video showed a simple method of measuring low resistance, this is a bit more complex because the device needs to be calibrated if you decide to build your own,.However, Wheatstone bridges are available in the usual places.The circuit i used as an example was from this sitehttp://www.rfcafe.com/references/popular-electronics/inexpensive-wheatstone-bridge-popular-electronics-march-1972.htm
low resistance without a microhm meter Sparky Projects 2019-04-07 | http://sparky-projects.co.ukpatreon.com/sparkyprojectsIn the video i use 10mA, this can be any appropriate current, it's best to use multiples of 10 for easier calculation, and once you work out the relationship of readings, it's easy to just look at the voltmeter, move the decimal point, and get a direct reading.Keep the current low, you don't want to burn out the trim resistor or the resistor under test.I was using a 5V power supply, but it's not important (but should be stable), as long as the 'power' doesn't stress the resistors

Laser Trigger Sparky Projects 2018-12-21 | Following the "Getting Attention" video, i have put the optical switch in a separate box, and made it more sensitiveI have also changed the optical fibre in the coil from a 'toslink' 1mm plastic fibre, to a 2mm glass fibre, which works much better.Getting Attention Video: youtube.com/watch?v=_Gbslc3FPgs
Getting Attention Sparky Projects 2018-12-09 | If you want to get the attention of an audience, you need to do something that makes them take notice, an explosion, a burst of fire, or in this case firing up a sparg gap Tesla coil, it's loud, and has a spark (albeit a small one)After a few iterations, i have finally constructed a compact Tesla coil there have been a few problems, the first design suffered from arcing, the second (in the box with a horizontal coil) also suffered from arcing from the secondary to the case, so the coil is now vertical.The other aspect i wanted was to be able to point the grounding rod (jesus stick or chicken stick) at the breakout point and have the coil fire up with the use of a laser pointer in the end of the stick.The idea is that the coil is disguised or hidden, only revealing what it is when fired up.This coil will have an unusual topload that no one will suspect, and it will seem as if the arcs are coming from the stick.I'm still having issues with the trigger circuit, but felt i needed to upload progress as it''s been a while since the last video.
YYYEEESSSSSS!! it works :D Sparky Projects 2018-11-18 | Well, a bit of a delay in getting this video out, had a few problems, but i got there in the endThis is just an indoor run, needs more tuning, but that can wait.This coil uses my synchronous (double contact) rotary spark gap, and my 'powerwall' transformer and capacitor set up.http://sparky-projects.co.uk
Garden run FAIL!!! Sparky Projects 2018-11-10 | We did a run of Green Meanie, my rotary gap (SRSG) Tesla coil, but then we got flashover from the rotary gap and that caused an issue.In this video i set about fixing the control consoleThe camera boom you can see in the video can be seen hereyoutube.com/watch?v=ELOT-RM7GmYWebsite with link to googlesite where the console diagram can be foundhttp://sparky-projects.co.ukThanks to Steve and Bruce for helping with the runyoutube.com/user/StevieLaneryoutube.com/user/bonusnudges

Green Manalishi (The circuits) SSTC without GDT ? Sparky Projects 2018-09-15 | Yep, i have got rid of the gate drive transformer.http://sparky-projects.co.uk/manalishi.htmlhttp://sparky-projects.co.uk/manalishicircuits.htmlOne thing i didn't mention was the BNC connector on the base, this is connected to the oscillator output and is intended for connection of a frequency meter and scope, the latter is for setting the mark/space ratio at 1:1
Green Manalishi SSTC (The Base) Sparky Projects 2018-09-03 | http://sparky-projects.co.uk/manalishi.htmlInitial testing was on low voltage with a 1Hz external oscillator, and LED's connected across each mosfet, this is the result youtube.com/watch?v=07pkkwPdU1oIn the last video i described the control unityoutube.com/watch?v=VNbHClgfpDIThis is the base unit that houses the driver electronics
Green Manalishi SSTC (control unit) Sparky Projects 2018-08-28 | Part 1 of 2 videosI've been working on this for a while, the reason is that i am using a different approach that i haven't seen before, much of the circuit was experimental, everything looks promising, but haven't done a full run on it yetYou can find the basic diagram on my website, the modules are mostly off-the-shelf items from Amazon, basically a square wave oscillator, 2 amplifiers, the interrupter was from The Geek group (Now the National Science Institute) but not available atm.http://sparky-projects.co.uk/manalishi.html

Putting up some resistance Sparky Projects 2018-08-14 | I hope you watched this to the end ;)Just a quick excuse to show off a few variable resistors, and an insight into one of the things i used to do at school.
Is this meter working ? Sparky Projects 2018-07-28 | The normal way to check a meter is to use a multimeter to check the resistance, but doing that on this meter seemed to show open circuit, so you would think because of the 6KV full scale, that maybe there's over 20M Ohm of resistors inside, but that's not the case, see whyThis meter doesn't need a rectifier to work on ACMeter specs:Ernest Turner Electrostatic meterModel 32
