SEW 1.7 METER ROKAKKU KITE FROM NYLON & HOW TO GET INTO SEWING KITES
Here I make a ripstop nylon version of the 1.7 meter by 1.2 meter rokakku kite and explain a little about how to begin sewing your own kites and other items.
link to Andrew Newtons UA-cam channel where there's some excellent vids showing detailed sewing of a rokakku.

BIG ROKKAKU KITE MADE FROM BIN BAG AND DOWEL DIY KAP AERIAL PHOTOGRAPHY
Переглядів 9523 місяці тому
Here I make a simple kite from binbag somewhat based on plans from a great UA-cam channel I'll link below. No great skills or expense required here. It did fly but in all honesty thin bin bags is not ideal as it stretches easily and rips easily. It is more of a proof of concept and if you want a permanent long lasting kite then ripstop nylon is by far the best material to use. See my next vid f...
CHAIN BAR LANE TUNNEL WALKWAY UNDERPASS ALDI DEVELOPMENT SITE HATTERSLEY HYDE TAMESIDE MANCHESTER
Переглядів 6464 місяці тому
Just a brief look inside the underpass on Chain bar lane and chain bar lane before it is wiped away by a new Aldi which is supposedly being built here. Interesting to think about all the people who may have lived here and remember it as it was. I wasn't sure if they will repair the tunnel or simply fill it in and block it off. It is somewhat redundant as it takes little effort to just cross the...
SEATBELT PARACORD ROCK SLING DIY SLINGSHOT LINKOSLING PIROUETTE STYLE
Переглядів 2104 місяці тому
Making and testing a seatbelt and paracord rock sling. Easy and quick to make and works well. Here I tried to gain more power by making it 160cm with limited results due to the density of the projectiles. If it was used with lead for example it would probably have more range. It seems the maximum distance I'm getting is about 200 meters. Perhaps with more rounded rocks this could be improved bu...
BRITISH RAIL TAIL LAMP FLASHING RED LED REPLACE DAMAGED CIRCUIT 2N3904 2N3906 EOT
Переглядів 168Рік тому
I bought off eBay and unfortunately it's battery had leaked ruining the circuit so I constructed a replacement using 2n3904 and 2n3906 transistors and 9 bright red LEDs. I wanted it to look similar to the original and flash a short pulse every 0.5 seconds which it does. 😄👍
REPAIR OR REPLACE BULB IN OLD CB RADIO SIGNAL METER WITH LED LIGHT EMITTING DIODE FIX MODIFY
Переглядів 1,1 тис.Рік тому
Here I add an led to the signal meter of an old Moonraker major CB radio in which the bulb has long since blown. It's an easy mod, just check the polarity of the old bulb wires with a multimeter, add a suitable resistor, in this case at 13.5v a 730 ohm is okay then a led, stick it back where the bulb was, glue it. That's it, jobs a good one!
CB RADIO LOW AUDIO FIX TTI TCB 771 WOULD APPLY TO MANY TYPES OF CB VERY SIMPLE REPAIR VOLUME MIC
Переглядів 495Рік тому
I got a cheap CB from eBay because there was something wrong with it but the seller couldn't quite manage to remember what. Well it took me a while and a bit of searching to realise that in actual fact the problem was nothing to do with broken or burned out components but just a loose solder in the mic lead. Took 5 seconds to fix. Hopefully this will help someone who has similar issue as it wou...

MIDLAND ALAN 42 CB/PMR446 RANGE TEST WILDBANK TRIG POINT 22 MILES TO JODRELL BANK SDR HOBSON MOOR
Переглядів 133Рік тому
Disappointing test, CB didn't reach at all which was surprising. PMR did okay on 0.5 watts but I forgot to save the recording. PMR on 1w was better. Not the best test to be honest but this is how it goes. I'll return at a later point and try again when it's not windy and cloudy. Brief but nice mooch. 🙂 I have been reading about the range issue and found this on 4x4cb dot com : ""Unfortunately t...
PMR446 TO CB RADIO CROSS BAND REPEATER LINK DUPLEX MIDLAND ALAN 42 FLOUREON FC200 27 MHZ 446 VOX
Переглядів 690Рік тому
Here I join the output from a pmr446 to the input of a 27mhz CB radio with the aim of creating a repeater. It could in theory be duplex but one way is adequate here. The idea being to increase range on CB by putting this setup up a large hill and using pmr446 to connect to the CB up high. I have decent receive capability on cb but on 4 watts range is severely limited. This repeater could improv...
DO NOT BUY MOUKEY MEP-110 DIGITAL PIANO KEYBOARD AFTER 9 MONTHS KEYS FAILED VERY POOR QUALITY
Переглядів 237Рік тому
DO NOT BUY THIS KEYBOARD!! I had it 9 months, play usually about an hour per day. Today a key completely failed and inevitably it is not going to last. The keys work similar to a TV remote control and have predictably worn out after a ridiculously short period. I do play a lot but I expected more than 9 months out of it. What it is is CCS, that's CHEAP CHINESE.....Yep! Exactly!! I think the pro...
REPAIR DAMAGED BAOFENG UV5R CHARGER CIRCUIT WITH TP5100 MODULE LITHIUM BASE DOCK FIX EASY CAR 12V
Переглядів 1,2 тис.Рік тому
Here I follow a method found online to fix a baofeng uv5r charger I broke by connecting it to the wrong charger and reversed the polarity aka knackered it. It has the advantage that now any 9 or 12v charger can be used not the exact voltage needed by the previous circuit. It can also be plugged into a car lighter socket. I think the voltage range is about 9v to 18v but check the specs of the mo...
PARROT RADIO REPEATER MADE FROM AN ACTUAL PARROT PMR446 SIMPLEX TOY TALKING FRS GRMS HAM CB
Переглядів 291Рік тому
Here I attempted in a pretty haphazard way to use the circuit from a breathtakingly annoying and irritating toy parrot or actually a hamster and use it to make a radio repeater. The circuit is already set up to do exactly what a simplex repeater does. I was not entirely successful but that's due mainly to laziness, with more care and choosing the right components to match the volume levels I'm ...
HIGH UK ELECTRICITY PRICES RANT DEAL WITH THEM BY USING VEGETABLE OIL FUEL CRISIS COST OF LIVING
Переглядів 83Рік тому
Just a rant about how electric prices have got ridiculous and how to lower them as much as feasibly possible. The solution is vegetable oil. At 9.2 kWh per liter it works out to be 17.391p per kWh for me with normal rates of 37.36p per kWh day rate 19.70p per kWh night. lol 1970, it seems like 1970!! Absolutely taking the Smeg they are! In the vid I say the wrong price for oil, it was £8 for 5 ...

Here I take the DTMF repeater recorder up a nearby hillside and leave it there overnight to allow me to test if it works as intended. It is about 2 miles away from my home base and about 60 meters higher although from two miles it's apparent angle above the horizon is only a couple of degrees. It is practically line of sight through a gap in nearby buildings. Sound quality is not ideal and coul...
