This Fixed Stick Drift When Even Replacing Gimbals Twice Didnt. Very Cheap and Easy. Plan C 2024-09-12 | Very cheap and easy fix to rectify stick drift on a controller or gamepad using only a couple of resistors. Worked when replacing the gimbals did not. Compensates for tuning at factory for original sticks.Cheaper than new gimbal. Minimal disassembly, fairly basic tools (soldering iron, solder, a few resistors)Worth a shot if all else fails. Should also work on drone controllers etc. will not work for Hall Effect (magnetic) based sticks.Video covers basic idea, testing different values and gives some rough suggested started test values. The calculation for resistors in parallel is complicated but they are just my findings through experimenting.WARNING! I SAY THE WORD 'POT' A LOT IN THIS VIDEO LOLGood Luck All

Hombrew Sinclair QL Power Supply Plan C 2024-05-05 | In this video, I build a power supply for a sinclair QL by following an old schematic I found on the internet. I talk through how the various power rails are created by the power supply and in the computer itself.I put the power supply through several tests and eventually hook it up to a real Sinclair QL.The finished product is pretty raw. I built it out of curiosity in order to try and learn something. I am not an electrical engineer, just a hobbyist with an interest. The video is for entertainment only. I am explaining it to myself as much as other people. The schematic that the power supply is based on can be found here:qlforum.co.uk/viewtopic.php?t=1231&sid=3ec386d4e2d8b262c7818ca09b8d70c9&start=20It was designed by 1024MAK M.Kinsey Example of MP1584 DC-DC Converter:ebay.co.uk/itm/36153517554615-0-15 3VA transformer I used:esr.co.uk/shop/contents/en-uk/p42421_15---0---15v-2.0A-30VA-Open-Frame-Transformer.html3D Printed power Plug Housing for Servo Cable:thingiverse.com/thing:6610958/filesEarly Video Showing ATX Conversion from Stock (inc 9v - rough audio):youtu.be/l8P8wsdjCFo?si=rHvsZZitELLHZaIU(No affiliations)Good Luck All

Atari 2600 from Oven to Heatsink (Light Sixer) Plan C 2022-11-05 | While refurbishing a couple of Atari 2600s, I experiment with a cheap and simple way to convert the RF can (which contains the mainboard and 3 custom chips) into a heatsink. The seed for this idea came when watching a video by @GadgetUK164 where he said it would be a good idea to mount a fan in or on the RF can (link below).Normally, the three custom chips slowly 'cook' inside the RF can as they get hot and there is very little airflow. It is literally like an oven!Over the years, the heat from the 3 chips had left heat/burn marks on the roof of the RF can!The 3 custom chips (RIOT, TIA and 6507) are no longer manufactured and date from the very early 1980s or even late 1970s. The chips in these units were dated early 1981. Chips generally last longer if kept cool.Replacements are available from retailers like Best Electronics in California but once they run out, that is it.Hopefully, this modification will help to keep these custom chips (and therefore the 2600) going for as long as possible.Good Luck AllGadget UK video that started me thinking:youtu.be/BP84oiKwGiA @17:15Orange paint mod for bezel here:youtu.be/qxfbHP4LmQw @13:42
Trying to Run My Combi Boiler off a 200W Power Bank Plan C 2022-10-23 | With all the talk about rolling blackouts this winter, I tried powering my combination boiler off of a powerbank which has an inverter.Even if you have gas, without electricity the boiler will not work as the pump, ignition etc all need power. I did a few brief experiments to see if it would work and tried to work out how much time it would give heating and / or hot water for in a blackout.On watching the footage back, the startup did briefly push the power drawe to 400W which is well ahead of the powerbanks rated output but it then settled back to well within limits. It started fine multiple times.Obviously, a generator would work too but these have limitations such as noise, being outside, not being able to use in the rain etc.These units can be had for as as little as £100 with vouchers etc. Please note this is just an idea and your mileage may vary massively depending on what boiler and powerbank you use and how you set the thermostat. I AM NOT SUGGESTING ANYBODY DO THIS. I AM NOT A BOILER ENGINEER!Good luck All.This unit:amazon.co.uk/Jackery-Portable-Explorer-Generator-Outdoors/dp/B08RNPYLQWOther units:amazon.co.uk/powkey-200Watt-Portable-Generator-42000mAh/dp/B08CN8TLH3
HP Pavilion Slimline, Black Screen no P.O.S.T. Power Supply Fix Plan C 2022-06-12 | A neighbour's old desktop PC showed strange behaviour. More often than not, it would not start and just show a black screen. It would not POST.I fixed it by changing a capacitor in the proprietary power supply. Not the most exciting repair but I thought I would document the process.The PC is an old Pentium Dual Core HP Pavilion Slimline desktop S3714UK but the principle would hold true for newer machines as well.Good Luck All

Acorn A3000 Extreme Refurb : Acid Damaged Acorn and a Magic POSTBox Plan C 2021-09-19 | This video documents the repair of an Acorn Archimedes A3000 which had suffered extreme battery damage. It was pretty much a complete strip and rebuild of the motherboard. The unit is then tested and brought back to full working order. A diagnostic tool called a POSTBox, which helped greatly with the repair, is also showcased.The unit was very kindly donated to the channel by GadgetUK164 and featured in his recent video:"Acorn Archimedes A300 Repair (From Hell)"youtu.be/iGhJbeUrA0YA massive thank you to GadgetUK for both the donation and all the help as well as to Zarchos, who donated some machines to GadgetUK in the first place. I am blown away by the generosity.The repair process is also documented in some detail in a thread on the Star Dot forums:stardot.org.uk/forums/viewtopic.php?t=23013The memory test script used in the repair can also be found there.This repair actually took months and was only possible thanks to the in-depth knowledge and patience of the people at Star Dot so a massive thank you to them as well.The POSTBox diagnostic toll was sourced from Star Dot. Details of the unit can be found here:myelin.nz/acorn/postboxContinuity tests spreadsheet and bare motherboard photos here:drive.google.com/drive/folders/17mnQDncaZLgUeX4i0YTH0fuGZ5GodSwY?usp=sharingPlease note: There were times when I gave up on the repair for weeks at a time and there were some parts I did not set out to video. I had to cobble together some of the footage. There are a few short sections of handheld video towards the end. A few sections have less than perfect audio. Not terrible but I have tried to limit them as much as possible.Credits:Music: "Mind Over Matter" by Jay Man - http://ourmusicbox.comCreative Commons — Attribution-ShareAlike 3.0 Unported— CC BY-SA 3.0 http://creativecommons.org/licenses/b..."drum-roll-sound-effect""Free Sounds Library"Free Sound Effects Site.Licence: License: Attribution 4.0 International (CC BY 4.0). http://www.freesoundslibrary.comGood luck All
Random Fix: Clone XBox 360 Wireless Gamepad Repair Plan C 2021-07-25 | I fixed a Xbox 360 controller clone (Easy SMX) for a neighbour. Nothing Earth shattering. The right hand analogue stick didn't go up or down. In this video, I replace the offending stick and make the parts sourced from Ebay fit this particular model. Fwiw, I think the controller was using gimbals based on the PS2.I assumed that these parts would be interchangeable - a clone Xbox controller would suit Ebay parts described as for Xbox controllers. I was wrong...Good luck all!
ARMSID vs Real 6581 SID (Re-Upload) Plan C 2021-05-10 | I originally put this up in September 2019 and then took it down with a bunch of other videos in a panic after some rap artist put a copyright claim in for me having a telly on in another room whilst I was doing a board repair video. (It turned out to be rubbish but it put me off Youtube for a few months).I have re-uploaded this video to try to help people hear a fair comparison of the ARMSID to the original 6581 SID as many 6581 chips are failing now and we need to figure out how to make a replacement.

PS4 Washer Fix, 2 Year Tweak! Plan C 2020-06-26 | I 'fixed' a broken PS4 off eBay using the washer fix about 2 years ago. It started playing-up recently ... just as I sat down with a new copy of The Last of Us Part II on Disc!Since I had it open, I thought it would be worth showing the washer fix in case it is useful to anybody else. This is a well-known trick and not my idea.This PS4 is an older model CUH1116A. It was originally sold to me (wrongly) as white light of death. I replaced the HDMI chip (not shown in this video) but it turned out it was really a blue light of death unit, which can be a bit of a nightmare.The washer fix got it going and it has been working ever since ... touch wood.Hopefully, this video may help others.Good luck All.

Testing a Few DIY PLA Options (A Bit More Scientifically) Plan C 2019-09-16 | I hooked-up a 74LS279 Latch circuit to my C64 test rig to test some DIY PLA solutions. The circuit tests for glitches in the PLA by means of a set/reset latch. I got the idea from MindFlareRetro's video below. I tested 45ns OTP ROMs with and without filters designed by Ray Carlsen, a supposed '906B' chip from eBay (supposed to be the only true drop-in EPROM - if you can find a real one), a couple of pre-programmed PLS100N's (the chip Commodore copied) and a known glitchy MOS PLA for reference. For the record, the eBay vendor that I bought the PLS100Ns from was very professional and issued my with a replacement without issues. He couldn't have been more helpful.The chips tested were:1) Atmel AT27C512R4RU - OTP Chip - Just CASRAM capacitor2) Same Chip with a DIY filter designed by Ray Carlsen: http://personalpages.tds.net/%7Ercarlsen/cbm/c64/eprompla/readpla.jpg3) eBay M27C512-90B6 - (no filtering)4) Genuine but glitchy MOS PLA 5) eBay PLS100NiNSPIRATION:Mindflareretro's video is here: The PLAin Truth About The C64 PLA youtube.com/watch?v=ofg33zk9uCA Ray Carlsen's pages are here: http://personalpages.tds.net/%7Ercarlsen/cbmGadgetUK164's Video which started me off here:youtube.com/watch?v=sT4OBNvboJ0ps I recently got a copyright strike from Youtube for using, of all things, circus music!

Fix Ethernet Cable Clip with Two Zip Ties Plan C 2019-09-07 | Easy way to fix an Ethernet cable which has a broken clip and keeps falling out. There are variations on this technique and it is not my idea but, as I had a broken cable, I thought I would demonstrate it.Requires only two 2.5mm wide cable ties. Saves an otherwise good cable.Also a good excuse to test out a new mic lol.Good luck All
Re-Homing a Repaired A500+ Board (The Hole Story Part II) Plan C 2019-08-25 | I wanted to turn the last A500+ board I repaired back into a full Amiga as the board was in very good condition. I sourced a damaged A500+ case that somebody had hacked-up cheaply from eBay and set about repairing it with a mix of 3d printed parts, putty & paint.

Fixing a Faulty Amiga 500 Plus Board: The Hole Story Plan C 2019-08-07 | I bought a 'non-working, for parts only' A500+ board off eBay as I wanted to rescue it. I negotiated a price but still probably overpaid lol.It had all chips stripped and was claimed to have a grey screen/no boot. When it arrived, I had a bit of a surprise! The hole wasn't the issue though...The fixes were pretty simple so I have detailed the whole process. To save you having to look at the schematic, I have linked a helpful picture that I found on the web and my half-arsed spreadsheet of the main connections below. The picture was by kipper2k on eab.abime.net. The thread is also linked below for reference.drive.google.com/open?id=17Z12ktTfPR3yjqNaXRsvwWxx7IkjVLu4Now she just needs a re-cap and a case...Good luck All.Different Agnus pinouts:en.wikipedia.org/wiki/MOS_Technology_Agnus#PinoutLink to EAB Thread I got the picture from:http://eab.abime.net/showthread.php?t=82924Music is:––––––––––––––––––––––––––––––Track: Affect — Vishmak [Audio Library Release]Music provided by Audio Library PlusWatch: youtu.be/5uh7qw3NPWAFree Download / Stream: http://alplus.io/AffectVishmak––––––––––––––––––––––––––––––🎵 Track Info:Title: Affect by Vishmak Genre and Mood: Dance & Electronic + DramaticLicense: Royalty free music for YouTube, Facebook and Instagram videos giving the appropriate credit. ———
Building and Fitting a Bwack C64 Saver v2.4 Plan C 2019-08-02 | Thanks to Bwack for open-sourcing version 2 of his awesome C64 saver!In this video, I build one, do a quick test and then fit inside a previously repaired C64. A lot of work went into the design of the Bwack saver and it's predecessor, the Ray Carlsen saver. They are both designed to protect a C64 from a failing power supply which can kill irreplaceable chips through over-voltage.Plenty more info at:Bwack Saver v2 Github:github.com/bwack/C64-Saver-bwackCarlsen Saver (plus Mobo fitting instructions & loads of other stuff):portcommodore.com/rcarlsen/cbm/c64/SAVERThanks to Bwack and Ray for keeping these machines alive.Here is the BOM I got from the schematic:Q2 = IRFR5305 (SMD)Q1 = 2N7000D1 = TL431C1 = 47uf 16VD2 & D3 = 6v8 ZenerR1 = 3K9R2 = 3K3R3 = 3K3R4 = 330KR5 = 3K3R6 = 3K9R7 = 33KR8 = 82KNo 0.1uf cap requiredGood luck all.
Getting into & Attempting to Back-Engineer an Amiga 500 (Heavy) PSU Plan C 2019-07-20 | In this video I gently open an Amiga 500 power supply which has very well-hidden screws and then attempt to reverse engineer it with a few homemade schematics.This is the 'heavy' / linear version of Amiga power supply. I take it apart in a non-destructive way so it can be put back as original. I just wanted to check the caps etc out but while I was in there I thought it would be interesting to try and figure out how it works.I go through my understanding of how each rail works one at a time. I did this purely to aid my own understanding but thought it may be useful to others somehow. Please let me know if you think I got anything wrong lol!The model is 312-503-02. Made in West Germany. I usually use a converted ATX but like to have the originals as well.Good luck All.
Is this Samsung Travel Adapter Genuine? Plan C 2019-07-16 | Wasn't sure if a Samsung charger I bought online was fake so I compared it against some known genuine ones on an old oscilloscope and then I tore it apart... What was inside was slightly unexpected. It is an ETA-U90WE. Apparently, Rev 1.4I modify it slightly to improve the output and will keep it as a spare.Update: I am now pretty convinced it is a good fake. I bought an identical unit from a reputable source for comparison. The fake weighs 47g, the real one weighs 53g. The model numbers are identical. The text is identical and the ink is identical. The real one shows shows max 50mV ripple at 2 amps and tops-out at 2.2a before folding back. The fake manages maybe 1.7a with severe voltage sag and more than 400mV ripple before collapsing. It also shows 200mV ripple at 1 amp. The real one increases output voltage to compensate for losses as the amps drawn increase. The fake does not. I also noticed a listing on Alibaba showing an identical board to the suspect one and the vendor has disappeared lol. It may be that this was an inadequate early revision but I doubt it. In any event, it hasn't given me any problems (apart from providing noisy power to my phone).Very difficult to spot. The main giveaway was the improper safety capacitor.Good luck all.Test Equipment Used:Hameg 20MHz Oscilloscope - Second-hand, eBayUnit-T UT658 USB tester - Purchased onlineBritish Standard Isolation Transformer - Second-hand, eBay60 Watt 30V Electronic Load - Purchased online
Replacing the MOVs in an Ageing Surge Protection Strip Plan C 2019-07-04 | After a lightning strike knocked out the router at my parent's house, I figured it was time to replace the Metal Oxide Varistors in my ageing surge protector strip. It was getting on and they wear out over time. Quick walkthrough of how I did it.Not the most exciting repair. Pretty simple preventative maintenance. Just a couple of pence on parts and a bit of soldering. Should keep it going for a while and keep it out of landfill anyway...It is also a good idea to put surge suppression on the cable modem coax...Good luck all.

Acorn A3000 Battery Damage - Complete Board Strip & Trace Repair Plan C 2019-04-18 | I bought an Acorn A3000 that was being sold 'for parts only' due to some pretty serious battery damage. I had to try and save it!Video shows complete teardown to board, removal of all components in affected area, neutralizing of corrosion, stripping back the solder mask from damaged traces and how I repaired traces and vias with a mixture of solder and magnet wire. I then reassemble and do a preliminary test boot.Also shows a way to jerryrig a 'Del' key to save the keyboard ribbon when testing the machine and testing of 74 logic chips on an eprom programmer.I probably went a bit over-the top but better to be sure. Many traces were rusty or had high resistance.Waiting on some new keyboard connectors for part 2::mouser.co.uk/ProductDetail/TE-Connectivity-AMP/7-520355-0?qs=%2Fha2pyFadujRi2Z6jxSELYK2qCaK%2Fu0lLKNZOnNcMpVpmJiy6B3FpA%3D%3DPart 2: youtu.be/Ae_-DW-ItEcPOST Error Calculator:retro-kit.co.uk/page.cfm/content/Common-RISC-OS-POST-failure-errorsGood luck All

Unscientific Testing of DIY PLAs on Five C64s Plan C 2019-03-25 | I made a couple of DIY PLA chips by following the instructions on GadgetUK164's excellent video here: youtu.be/sT4OBNvboJ0I then tested the substitute PLAs in each of my five C64's.The tests are not very scientific and were done more out of interest than anything else.For an in-depth discussion of the workings of C64 PLA (and different replacement option including the PLAnkton) see Mindflareretro's excellent video here:youtu.be/ofg33zk9uCAUPDATE: I subsequently repeated this experiment on these 5 machines with some M27C512-90B6 Chips from Ebay. I am not sure if they are genuine or not. They are marked 'Korea' and claim to be made by ST Microelectronics.These worked in ALL my 250407 boards (1*Rev A, 2*Rev B and 1*RevC) for at least 20 passes of the diagnostics cart and no capacitor was needed between CASRAM and Gnd. I got all excited and bought 10... Then I discovered that the chip does not work on my 250425 board. The diagnostics would not run and strange key presses were returned under normal operation. It has been suggested that removing Capacitor 203 on this board may improve things with this chip, but I could not find C203 on my particular 250425 board! Here is a link. I have no affiliation and am not sure if they are real or not.
