DIY Off Grid Solar Project

Image
First budget set up £1000 Normally I start with waffles so let's dive straight into the technical details first this time. Any feedback and warning welcomed as this is my first attempt. I installed two 375W Eurener Zebra solar panels: one on my south facing conservatory roof and one on the back wall. Solar output peaked at around 600W combined (parallel). I overspec-ed it due to the flattish wall placement and in anticipation of reduced winter sunshine.  [Update: October autumn day averaging only 1.5kWh -- 0.3/0.6kWh when cloudy and 2.5kWh when full sun.] [Update2: As the winter sun gets lower, the panels fall into more shadows.] The panels were chosen for the low weight (19.2kg) to efficiency (20.6%) and ones that I can collect by car; quite often panels are delivered in pallets costing around £50. The 3.3m aluminium mounting rails were hard to source but I was lucky to talk them into supplying two with the panels and fitted nicely into the car, just. Important solution maximise t...

First Post Covid Flight with MAS Business Class

MH3 LHR-KUL July 8, 2020 When I first set sight on the seat I admit to be underwhelmed after walking past (what I now know to be) one row of Business Suite but mostly was disappointed by the lack of screens (I had imagined a modified self-contained pod). But as I sat down and familiarise myself and started the massage chair, I begin to feel both amazing fortune of enjoying such luxury and sadness that why I or every one of my family haven’t or probably won’t be doing it every time! Took a while to realise that business section do away with the center hanging baggage hold, accentuating the vast high ceiling, givng a spacious feeling (if you sit near the back) Economy was full on this MH3 A350! Mostly students going home for summer holidays. The girl behind my original seat 7A wore Imperial College Business School. Although no screen, there is no one within 2 meters. That’s mainly because it is only half full. Friends tell stories of being upgraded but I’m reli...

Brexit: no-deal and the Irish backstop

The road to Rome is paved with gold What Theresa May said but never meant. Now Boris is saying it and don't know if meant it or not. At least the city bought it given how the pound has sunk today. But as one reviewer put it: if the reason to prepare for no deal is to get EU to offer better terms then it's a good strategy.  if it's to be prepared for no deal when the EU doesn't budge, then it's a good strategy.... The referendum was poorly executed - that's without doubt and the reason for liking current approach is Boris gov now actually tells the truth, and not afraid to say it's a bad deal, and challenges the remainers MP to trigger the nuclear option - revoke Article 50. The referendum had some provision built it such as: 60% to trigger article 50, or if Brexit won immediately hold another referendum to decide the type of Brexit. The return of of the prodigal son  Just as well that all parliamentary options are exhausted while May...

Yamaha MCR-B043D Micro System Review

Yamaha MCR-B043D Review Like it despite all its problems.... Unique tiny square speaker pair that looks stylish and totally discrete in the dining room. I was coming more up from a sub £200 DAB/Bluetooth speaker than Hifi separate standpoint – not as portable but adds great stereo and USB playback option. I’m not a garden/pool party kinda person and UK doesn’t have that kinda weather for it. It has all the music connection I need (USB is mp3/wma only, no wifi/network). I’m using the USB playback more than I expected but unfortunately there are occasional USB decoding crackles at the start of random tracks. Speakers are not attached which is a bonus. Sound is surprisingly good coming out of the 11cm woofer in only a 4L box with 13cmx13cm square area. The overall sound quite balanced and imaging is ok. Serious air movement coming out of the rear bass reflex port and it can go quite low (registering even 30-40Hz bass) but playing Beyonce Deja Vu or Hotel California pr...

How to child-proof your iPhone/iPad

How to stop kids deleting your videos and photos? Learned a new trick today and it was such a revelation to me! Like all parents who had to hand over their iToy to the little ones from time to time, it last thing you want is your apps or photo/videos being deleted or worse still having the little ones calling random people in your contacts:) Enter Guided Access . (General -> Accessibility -> Guided Access) In a nutshell it enables restriction on the app you triple-click the Home button on. Not useful enough I hear you say? The true revelation is the freehand masking of the area that you don't want the little one to touch. Simply shade off any number of area and off they go. The masking feature can only be applied after the passcode is entered and it's in a "zoomed out" mode. Going on a weekend trip to Peak District tomorrow and look forward to trying it!  Important Tips : Make sure that while you are masking the restricted area, you rotate the phon...

Under the microscope

Update 8.0.1. Incredible that not even Microsoft managed that kind of scrutiny when a windows release or update goes wrong. The fact that Apple released iOS 8.0.2 the very next day flew people by and all your brain is left with is the impression that the 8.0.1 contained a network bug for a few users in Australia. Ok maybe you wasn't aware of the last bit... I feel like the folks of Axiom in Wall-E, the arms just not long enough to reach for the remote to save themselves. In this case the letter "O" and "P" on the keyboard of my iPhone 6 P-L-U-S are just out of reach of the mighty thumb. It's a ridiculous phone, i.e. it's an insanely crap one for one-handed operation I've been so used to with the iPhone 5. So I kept telling myself I have 14 days to change my mind. I went into a shop and tried out the iPhone 6 again but it just doesn't have the same vibe. Clearly I'm having some fun with the folks. #   ...

Efficient Market Theory Poof!

Something that puzzles me a lot is the valuation of some large cap stocks. We all heard of the efficient market theory but I'm thinking of stocks like BP, Vodafone, even the latest Royal Mail IPO or Tesla and Facebook. Take Vodafone. They just sold Verizon Wireless to Verizon for U$130bn, and yesterday has a market cap of U$170bn. It seems badly priced. Worse if you think 3 months ago when it's market cap was U$140bn (U$10bn for their non-US, global, operations and assets, including a UK 3G license they paid U$10bn for and cash - granted they have GBP40bn in debt)!! Now AT&T wants to buy up Vodafone, sending shares even higher. I mean who wouldn't at this silly valuation? Can it be true that this Verizon deal that has been on the cards for the last 10 years could lead to their top shareholder, Neil Woodford, the best rate fund manager in UK with the largest fund in the UK to dump all his Vodafone shares (that he held more the donkey year...
