playing around with electronic valves

Way back when the TV channels closed at midnight and you were left with a little white dot on the TV, when milk and pop was delivered to your door and no one had ever heard of the Internet I started my career in electronics, first as a lab technician then moved onto TV repair. Back in those days, valves were still in use and I had to learn how to fault valve TV's, radios and amplifiers (1983). For some strange reason valves grew on me, they represented a wide range of skills in producing for example a radiogram from the metal chassis, to the electronics, the veneered cabinets and intricate tuning mechanisms - it was all there plus that "valve sound"

I've managed to "keep in touch" with valves and the love still continues - I own a valve amplifier - a big beast and a joy to listen to and stare at - it's a bit like coming home to a real fire - something to stare at :)

So, along comes an opportunity to do something different, away from the world of I.T, little black boxes with flashing LED's and fans. A client asks if I know anything about valves and says he has a headphone amp that does not sound as good as it should. He drops it off and I try a few weeks of listening tests - he's right, it sounds harsh, no clarity. So a strip down and a peek inside reveals a few short cuts made by the manufacturer. Some I don't really understand why, like the 4 resistors wired in parallel or the very low-grade capacitors but hey ho, there is at least a lot of room for improvement.

So, the first thing to do is check it's current performance, for this we need a multimeter, function generator and oscilloscope. After this we will change out the 6 diodes for fast switching diodes, change those 4 resistors and replace with 1.
Get rid of the power supply capacitors and replace those with high quality Panasonics, the input caps don't really need to be there but as I'm not sure how this will be hooked up to external equipment, I'll replace with better quality and double the uF of the caps. The 4 output caps will be replaced with 2 1500uf caps, again, audio quality. I'll also check the ouput transistors for bias and comapre channels to see if they need matching up or replacing. Plenty to do and with all this snow currently around, the perfect chance to start playing

large scale wifi project for nursery

G17 is very excited about this project in that it provides a number of challenges to overcome in getting WIFI to a nursery so that at any time, our client can remain in contact with the internet should they wish to upload plant data, plant images or respond to emails without having to repeatedly go backwards and forwards to the office which is time consuming and disruptive.

The image above is just a small section of Nursery, to the left and right the Nursery expands out further.

The challenge here is going to be around line of sight and wireless power levels with glass houses made of metal mesh which could reduce the signal strength. Added to this is the lack of power in fields - but with modern day electronics, solar power and energy storage to power energy efficient AP's in a mesh, we should be able to sort something out - more to come…..

Hotel PBX Telephone System
new pbx installation

Local hotel required a new PBX installation due to their old one packing up and beyond repair. G17 provided 2 specs with options to meet current phone capacity and options to investigate a reduction in phone capacity. G17 also carried out a survey and suggested that a data cab would be far better to enable the installation to be kept secure and tidy which would help in any future faulting, provisions and repair. As some of the devices in the PBX area contained sensitive information and were also located close to public areas, a data cabinet would allow for a more secure installation.

Based on customers’ requirements and budget, G17 put forward two options for installation for their new PBX system and listed the pros and cons of both systems

This new system had to also integrate with their current wiring infrastructure as any additional wiring installations would significantly increase the cost of the installation. With this in mind G17 proposed an Orchid 416 telephone system which would provide a like for like service from the old PBX with the added ability to allow the hotel to move across to VoIP when suitable but also keep all the features of a traditional PBX system.

G17 is proud to have been instrumental in providing Montgomery Town Hall and Broad Street with Public WIFI access enabling the Town Council to offer WIFI services to visitors, residents, business and community events.

Using the latest in WIFI technology, the installation has been future proofed and is adaptable to future technological changes while also ensuring compliance with relevant public access requirements.

Providing WIFI hardware components for such a historic building had met with some challenges. Asbestos areas had to be identified and avoided and cables had to be kept out of sight. Providing power to each AP would have involved additional expense so PoE AP's were used throughout. Public hotspot servers have also been deployed to meet with current UK laws and these have been configured with DNS proxy to ensure a level of filtering. Remote access to the whole system was also required so the site, equipment and configurations can be managed remotely.

One thing I love about building these is the insight into the lives of these people. Darren has a genuine love of the wild, nature and its inhabitants and making the best of the surroundings to ensure protected species have the best chance possible where us folk wish to tread.

farm cctv repair & test
G17 CCTV repair for local farmer

Local farmer with an extensive range of farm machinery approached G17 with an enquiry for CCTV repair on a system that had been installed over 5 years ago. G17 carried out a survey and agreed to try and get all 10-camera’s working plus CCTV recorder. The recorder would not view any images from any of the camera and was also not recording. Further investigation revealed that the hard drives had failed and internal fan had stopped working. Luckily all that was wrong with the camera were bad joints and power feed failures. Three cameras are PTZ (Pan Tilt & Zoom, as shown in the image above) so the data pair had to also be checked for continuity and data.
With 2 new CCTV compatible hard drives installed, a new fan and a software update the CCTV was as good as new. Old taped joints replaced with grease filled crimps and new power feeds all 10 cameras are now working. Our client was impressed with the success rate of the repairs and we are now in the process of alarming some of the offsite lock ups - deploying some very useful technology
