mending things

I recently decided to dust off an old gaming PC from around 2006 that was in the attic. I'm interested in folding@home , a way of assisting medical science donating computer time from home , and  wanted to see if I could build a dedicated FAH (Fold at Home) rig using spare hardware we had.  I'm also interested in computational heating i.e better exploiting the waste heat from computer systems . This  will be the subject of another blog shortly, but when I got this PC down and booted it up, I immediately hit an issue with the LCD screen. It kept turning on and off approximately every second , but sometimes staying on for longer. I could see the boot screen, the BIOS and eventually the windows logo, but the screen wouldn't stay on. Very frustrating I later realised that if I left the monitor on for at least an hour it would stabilize and become usable. I looked around  on the internet and realised this was probably a problem with the capacitors in the power supply. If...

I'm ashamed to say that recently I noticed rust developing at the base of the microwave interior glass door panel, and the paint flaking. Cooking items like potatoes releases a lot of moisture , which probably should be wiped away immediately to avoid this, but when you are preparing a meal and everything you forget (or I do at least). The Microwave is a Bosch and has a face plate so it fits into a recess in our fitted kitchen. I looked into replacing the door but Bosch do not supply this as a spare, not could I find a donor oven online. A whole new oven would be around £300, which seemed a lot for a problem that might be fixable.  I read online about Rusty Microwave ovens, and advice ranged from " It'll be fine " through to " immediately remove the oven and place in a lead lined container at the bottom of the sea " type of response. Filtering the informed advice from the hysterical took a while. In the USA you can purchase Microwave oven pain...

I have had a 4 slot Dualit toaster for the last 15 or so years, and it has worked well. I replaced one of the heating elements some time ago, covered in another post. The timer switch had recently become unreliable, sometimes when you turn it, the red "on" light didn't engage and the elements didn't come on. I ordered a new timer from Dualit, which was not cheap , £27 from Dualit via their website, but I like the toaster and don't like throwing items away when a small part fails. The spare duly arrived and this is the fairly easy replacement procedure. NOTE : TOASTERS USE MAINS ELECTRICITY. ONLY ATTEMPT THIS IF YOU ARE COMPETENT WITH ELECTRICAL REPAIRS.  ALWAYS ENSURE THE ITEM IS FULLY DISCONNECTED AT THE WALL FROM THE MAINS SUPPLY BEFORE UNDERTAKING ANY OF THE FOLLOWING To gain access to the timer you need to remove the crumb tray and flip the toaster on its top. I use a plastic tray to sit the toaster in, collecting any screws and bread crumbs tha...

A number of my posts here regard my battle to replace GU10 and MR16 Halolgen bulbs with LED equivalents, via a short period of CFL bulbs. This has been successful, with all the 40 halogens having been replaced with LED some 5 years ago. My energy consumption has gone down and so has the amount of heat generated into the loft and ceiling space from the bulbs. Since then I have kept an eye on LED full size light bulbs for ES (Edison Screw) SES (Small Edison Screw and Bayonet fitting bulbs, all of which are represented in my house. Until recently I had found the LED lightbulbs to have dimmer light and a cold blue tint, much as the first Halogen replacements had. A few weeks back while in my local B&Q DIY store I saw a display of Philips LED Bulbs, some of which featured clear glass and a kind of internal perspex crown-shaped diffractor. I'm pleased to say I have tied both in SES , ES and Bayonet form-factors and they are superior to the Com...

Common themes across most of my posts are energy conservation , its monitoring and technology. This post sort of combines all three in one. We have a Sky+ satellite unit with integral hard disk recorder. In the UK this is known as a Sky+ box. The unit can be programmed to easily record programmes 24 hours per day and record complete series at a repeating time. It has lots of features, including OnDemand  services where a wide range of channels are recorded on the off chance you might want to watch them. My specific Model Sky + HD unit is made by Amstrad We also have a 46" Samsung LED TV which is hooked up to the Sky+ unit . I use a CurrentCost household energy monitor, which is hooked up to the internet via a unit called a netsmart, also from CurrentCost (see my other post on currentcost). I can see on a web page a graph of my household energy consumption in close to real time. A 3rd type of device from CurrentCost is the Individual Alliance Monitor (IAM) which is a unit whi...
