- Pinned MAC Fan Broken? ok so yesterday i was surfing the internet, when it all started to go really slow, then my fan started to make some noises... took a look in settings and downloaded a few fan control applications, and it reads -1RPM for my right fan... so im assuming its broken, or maybe just blocked? anyone have a similar problem and know if i can fix it myself without having to actually send it back for repairs?

- Pinned Now this is a BIG spider – and it won’t bite. Quote: Huge six-legged robot built in UK by enthusiastBy Zoe Kleinman Technology reporter, BBC News Inventor Matt Denton shows off his robotic spider creation A giant-mantis robot with hydraulic legs has been unveiled by a designer who spent four years creating it. Matt Denton, from Hampshire, estimates his "very expensive toy" has cost him hundreds of thousands of pounds. He says a mining company and a marine research organisation are now interested in his design and he hopes it might be used at science fairs. During its development the machine had one outing, at a music festival, where Mr Denton says it was well received. "It's an entertainment vehicle," he said. "But I hope it will inspire people." The project was only initially intended to take 12 months, Mr Denton, who usually specialises in small-scale animatronics for the film industry, said. "After 18 months we tried the model out. We had to completely strip out and rebuild the legs. They were too heavy and complicated. Matt Denton Animatronics expert Matt Denton says his machine's legs are inefficient "I'm a software and electronics engineer so this was out of my area - I had to learn fast." The robot, driver-operated by joysticks within a cockpit, can only travel at 1.5km/h (1mph) and manage a distance of 5km on a 20-litre (4.5-gallon) tank of diesel. "It's not about miles to the gallon, it's about gallons to the mile," he said. "It wasn't built to be efficient and fast. It was built to look cool and insect-like and fun." Mr Denton said he was inspired by science fiction to create the "walking" machine. "But legs are very inefficient - the wheel was invented for a reason," he added.

- Python : controlling the Arduino pager transmitter from a Linux server Managed to make quite a bit of progress with my Python coding over the last few days - wrote some code to control the Arduino based UHF pager transmitter I built a couple of years ago and even provide a very basic UI for entering messages. an earlier version of the code (without the UI) in action: https://www.youtube.com/watch?v=dBTbribgmJ8 most recent version: https://www.youtube.com/watch?v=H_aQm2fzjNc Even worked out how to use git, so there is a repo for the code (very basic and missing install instructions such as the various Python dependencies https://gitlab.com/Alex-rtnVFRmedia/pagertest2

- US : Radio Shack seems to be finally going tits up Amazed TBH it lasted that long, although to be fair not everything from there was junk, especially during . the 1980s and the late 1990s. Alas, when Rat Shack equipment got sold in UK via the Tandy subsidiary half of it was way overpriced (especially computers in 1980s) although there were also bargains to be had if you looked carefully. it was worrying though how the USA management managed to trash a company which wasn't doing that badly during the late 1990s. Maybe there is some stuff in the clearance sale DB and other Americans might be able to make use of (and it would even now be being sold at a reasonable price). https://www.radioshack.com/pages/bankruptcy-announcement

- What's inside a BT exchange? So on the Island where i live we have a small BT exchange and for years iv'e been curious to what's inside. After many times asking my local BT engineer i always got the same response "That's top secret mate!" Last year about this time he forgot the key and had to force the door open to fix some shit, I caught wind of this and thought heres my chance to find out. I waited till he fled the island to go home and took my torch for a wonder inside. Here's what i found. If any of you can identify any of the technology please spill the beans.

- improved mains cable on cheap charger for portable UHF radio These UHF portable radio sets are good value, but the supplied mains chargers aren't the safest design (and also cook the accus if they are left on charge constantly). you can buy better 6 unit chargers from HongKong, but in the meantime I investigated and modified one of those I already have to make it slightly safer - which was a fiddly and awkard job due to its construction. I would not suggest doing this unless you are confident with working on mains voltage circuits! At least it all worked when I put it back together, the mains circuitbreaker didn't open nor did I take a hit off strong voltage and the output voltage is correct raaa. I made a couple of slides showing how it all fits together (and an overview of how these power supplies work - many mobile phone and USB chargers use similar circuits)

- DE : Das Elektronik-Labor von Burkhard Kainka DK7JD (auf Deutsch) The bulk of this site is in German (there are one or two English articles) but the editor is a big advocate of open source and hobby electronics and has written it for all ages so if German is not your first language it is still fairly easy to follow. Literally hundreds of articles here, covering many diverse areas of electronics (basic analogue stuff, microcontrollers (Arduino, RPI and others), radio circuits and useful hints and tips. There are also links to sources for components that can be harder to find (and these suppliers do also have English sections on their sites). Das Elektronik-Labor

- C Programming : controlling a cheap thermal printer via USB to TTL serial comms link Should work on x86/x64 Intel and ARM (although haven't yet tried it with a Raspberry PI) - set permissions correctly for the /dev/tty* device so you don't have to run it always as root.. Of course using Python is way easier (as I found out when trying to write code for another serial comms project) but I was determined to get the C code working somehow, the code is below if anyone wants it.. https://www.youtube.com/watch?v=7ZipTQTyPn0 link to code: Thermal printer code test – rtn VFRmedia

- Holiday Christmas Window Effects Projector Hi there I just recently bought this Holiday Christmas Window Effects Projector from a company local to me in Cardiff called Digi4u and I thought I would post it here with some of my thoughts. I went in store and was shown a Youtube video that showed what it was and really it looked great. They had projected a bunch of animated videos directly onto their frosted windows outside and you could see the image clear as day. (I’ll put the video below). It looked great and I couldn’t believe it was that simple to do, as I had thin curtains in my front room they said I could just project straight onto them and the video will be able to be seen from the outside, but if not then I could be instructed on how to make a vinyl projector screen cheaply from a Youtube video. I was also worried about how big and clunky the projector would be in my house (as I don’t have a lot of space to spare) however they showed me that the projector was barely any bigger than a Smartphone, a Lot smaller than I first thought. The Video Effects Videos were also bundled with the Projector on a Micro SD Card which could be inserted directly into the projector so I wouldn’t have to faff around going to websites and trying to find them. I bought the Projector set for £60 pounds in store which I believe is the same price as their website (which I will link to below if anyone is interested). When I brought it home, I found it really was as simple as they had made out. I pointed the projector towards my window, inserted the bundled Micro SD Card into the back, selected the videos and pressed play. First impression was that the picture quality was quite impressive. As I said before the projector is very small, barely any bigger than my iPhone 6 so I wasn’t expecting miracles but it really was good, and the speaker on the projector was very powerful. I have bought Bluetooth wireless speakers in the past which sounded worse in honesty! After setting the video up I walked outside and found that sure enough the video was showing on the entirety of my window. It really did look the part. So now I am having this Video FX projector as the centrepiece of my Decorations this year and its already drawing looks in my neighbourhood. Here is the video that I was shown at the store: https://www.youtube.com/watch?v=t8esJYj88A4&t=2s And here’s the link to their site in case anyone is interested: https://www.digi4u.co.uk/digi4u-christmas-window-effects-fx-holiday-projector/

- MY/JP/KR : Samsung and Panasonic accused of abusive labour conditions in Malaysia This is particularly bad, as only recently MY was becoming one of the more advanced countries in the continent for improving conditions of electronics industry workers - added to which equipment built by exploited workers (at any point in the manufacture chain) is also likely to be unreliable and even be dangerous. Thankfully I have no current need for microwave ovens (the one that my parents got in 1991 and was in our family house for decades is now at my house and still going strong!) but it is an increasingly dilemma now buying any tech, as what were "good" brands (both for reliability and responsible business) even 5 years ago seem to go increasingly down the sewer very quickly... https://www.theguardian.com/global-development/2016/nov/21/samsung-panasonic-accused-over-supply-chain-labour-abuses-malaysia

- UK : East : E-bike+SSD portable disk vs UK rural broadband, data transfer rate test.. One of our rural sites uses a patients database which is about 17 GB in total. The broadband at this site (a combination of two ropey British Telecom ADSL circuits + a satellite link) is way too slow and unreliable to transmit amount of data (the satellite is on a data quota as well during daytime, and in the night everywhere from Wales to Istanbul is trying to access the satlink). So I have to manually collect the weekly backups from this site (14km from where I live) one I have triggered them remotely rather than upload them to secure cloud storage. I had to ride there anyway to deal with a misbehaving computer in the basement nurses office (which hadn't got its remote access activated) as well as a server update, so also created two more datasets of backups stored on a USB SSD. So there was 50 GB in total on the disk when I rode back home. I use a cheap Windows phone as a GPS unit with ride tracking software -this shows it took me 35 minutes 33 seconds to travel the 14km on my e-bike (I rode slightly slower due to the weather) 50 GB is 51 200 Megabytes. 8 bits in a byte, so this is 409 600 Megabits (to simplify things I've left out any padding bits used on a serial data circuit and/or network overhead from packet headers etc; but this does also mean I am only counting the actual useful data in the backup). 35 min 33 seconds is 2100+33 = 2133 seconds. So the data transfer rate is 409 600 / 2133 = 192,03 MB/s :cool: (even with VDSL the upstream on most circuits is only 10MB/s)
