Announcing<br />
<br />
After getting some teletext editing software running, I have made a start to producing a monthly Teletext Magazine, you can subscribe to it on a new channel of mine, I hope other people can contribute and also get subscribers to the channel.<br />
<br />
As the project progresses I hope I get more content and wordy type things like reviews and commentary.<br />
<br />

<br />
As you can see it is very easy to drive the wheel with any spindle that fits, I decided to use a panel pin and made a tiller, rather than a wheel, and then decorated it with some mecano.<br />

<br />
In the last six months or so I have become increasingly bored of normal broadcast radio. As a result I have been downloading plenty of podcasts.<br />
<br />
The programs that get a regular download are<br />
<br />
<a href="http://www.hellointernet.fm/" target="_blank">Hello Internet </a><br />
<a href="http://www.whmpodcast.com/" target="_blank">We hate movies</a><br />
<a href="http://www.stuffyoushouldknow.com/" target="_blank">Stuff you should know</a><br />
<a href="http://shows.howstuffworks.com/techstuff-podcast.htm" target="_blank">Tech Stuff</a><br />
<a href="http://hackcircius.com/" target="_blank">Hack Circus</a><br />
<a href="http://answermethispodcast.com/" target="_blank">Answer me this!</a><br />
<a href="http://shiftrunstop.co.uk/" target="_blank">Shift Run Stop</a><br />
<br />
Now the last one in the list is my very favourite at the moment, as I managed to get a name check, I recently sent in my <a href="http://retrotext.blogspot.co.uk/2015/01/sinclair-mobile-phone.html" target="_blank">concept Sinclair Mobile phone</a> as I was very impressed with their show and wanted to send something in to them as a thankyou. I have only managed two podcasts and can honestly say how much effort that was for content- so doing 75 is quite a feat.<br />
<br />
I would also recommend Hack Circus, this is a project that is run by co-presenter of SRS Leila she has guests that have opened a new world to me about hacking and understanding things in a new way.<br />
<br />
<br />
<a href="http://shiftrunstop.co.uk/2015/02/22/episode-75-novelty-automata-and-serious-snacking/" target="_blank">So here is a link to podcast- I hope you enjoy it.</a> add it to your podcast thing.<br />

I have been saving up various parts for a project like this.I considered using the Raspberry PI, but its lack of VGA for the monitor I had was a deterrent for this.<br />
<br />
Luckily enough my old PC would fit the bill perfectly, I installed Lubuntu; a light weight operating system that would run mame and provide USB support.<br />
<br />
This was fairly easy to do, but when it came to dropping the tower into the cabinet it would not go! so a stripdown was required.<br />
<br />
The controls were mapped to a great little usb interface that I picked up on ebay for £6, I gave the unit and legs a respray and touched out big blemishes in the wood work.<br />
<br />
Other modifications were needed, the power switch and the status LEDs were broken out to the old site of the slow blow fuse, and the speaker is now powered by a stripped down PC speaker amp.<br />
<br />
That Tube you see is a tumble drier exhaust to get the heat of the PCB straight out of the cabinet via the vacant speaker grille. The credit button is a push to make switch glued to the coin reject mechanism so when you push the button the innards close the switch, this avoids making holes in the original cabinet.<br />
<br />
Another pc fan was added in the site of the older air intake fan from the 1979 build to keep the temperature down in there, and I have a few games installed that only use the left/Right controller and one fire button.<br />
<br />
I can manage the files from any other computer as I installed a SSH client to it, so remote maintenance can be preformed easily.<br />

<br />
Sinclair made an attempt to get a foothold in the fledgling mobile communications industry in the late 80s?<br />
<br />
Pitted against Motorola, Ericsson and nokia, what would the Sinclair Brand introduced?<br />
<br />
Perhaps this would have been a possibility.<br />
<br />
The Sinclair Mobile.<br />
<br />
800 MHz Antenna<br />
Full floating keypad.<br />
4 preset memories<br />
Keypad lock<br />
SOS button<br />
Short Messaging Service (SMS) compatible.<br />
2" Screen<br />
<br />
Sinclair could have been the British IBM with computers, but they may have been the British Apple with the evolution of the Sinclair phone.<br />

<br />
Well pleased to have picked this up and record it, I used a Sony voice recorder and pumped it into audacity for the upload.<br />

Would be great if I could find out about what she was explaining.<br />

<br />
SO after <a href="http://retrotext.blogspot.co.uk/2014/04/zx-spectrum-compact.html" target="_blank">slimlining my ZX Spectrum +2</a> I decided to try to make the Arcade cabinet a wee bit smaller.<br />
<br />
Since fixing a junk 19" monitor for my PC I have used to use the older monitor in the cab, replacing the Grundig CRT. This allowed me to chop a whopping 10 inches/ 22 cm off the back and make it fit snugly to my wall.<br />
<br />
It still safely free stands, but is easier to move about.<br />

The Device has plenty of potential, to be on the safe side I will Blog this as a neat way of listening to Commercial Radio Stations, you can web search to reveal how to listen to the ISS and other cool things.<br />

<br /></div>
<div class="separator" style="clear: both; text-align: left;">
HI Folks!, not been as prolific for a bit, one reason for this is the<a href="http://rvgpodcast.blogspot.com/" target="_blank"> Retro Podcast that I am working on at the moment</a>. but I wanted to update you on another retro project I have been slowly (for a change!) working on.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The display wall.</div>
<div class="separator" style="clear: both; text-align: left;">

The whole idea of this started from a tenuous origin, my youngest son over the summer holidays was keeping himself amused one day with some hama beads. These little bits of multi coloured plastic can be arranged on a matrix and the ironed to meld themselves together.I asked him to make me some space invaders, I was so impressed with the effect I commissioned him to make me more, he had ice cream in return.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I have a rather grotty boring magnolia wall in my office/ box room so I thought I could paint a backdrop and glue his invaders up, I painted an area a bit too large to keep my son's enthusiasm for making these sustainable, it quite boring if you like playing football in the park so I was left with a bit of a void to fill.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
After a visit to the )2 area in London I saw an awesome way of displaying old retro memorabilia,</div>
<div class="separator" style="clear: both; text-align: left;">
I did not take a photo but there is one here that is from <a href="http://independanttravelhelp.com/">independanttravelhelp.com</a> </div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
there are an amazing amount of lps and tapes countersunk into the wall, and those Marshall speakers are real!</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
There is a touch screen that allows you to plug in your headphones and select any track you like.</div>

<br /></div>
<div class="separator" style="clear: both; text-align: left;">
AS I have a small collection of games and computers that are stashed away, that do not get much appreciation I set about filling the rest of that black square up with some of the more interesting things that were A:Flat and B:light.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">

<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The fundamental rule of the wall was that any item must be able to be removed and placed back, after all I do get enjoyment from these items, my NC100 and gameboy games are regularly used, so glue was a no no.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The solution to this was to use plained batten wood, measured and screwed to the wall so that all the objects could be squeeze held.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
As an extra touch I wanted to play the PS2 games, they are mostly all compilations of arcade and retro consoles, Atari anthology, Sega Megadrive collection and Taito legends and the like, so I salvaged a 7" tft monitor and mounted it along with a playstation 2 to the all, I managed to hide the wiring in the trunking that I used to hold the smaller, lighter games in place.</div>
<div class="separator" style="clear: both; text-align: left;">

This is the whole wall so far, I need to paint the magnolia area black, but I am still adding at the moment.Click the image for a closer view.</div>

As the playstation runs older PS one games, I now can play them on the wall too.The Summer games box is held with velcro and hides the plugs and connections.<br />

A little while back I wrote a short article about the early home built system from the 70s and 80s I discovered some very interesting systems and spoke to some interesting people about their recollections of using and building the machines back in the day, including the Galaskia and Micro Kit 101.</div>

You can get the make file to do this yourself here from <a href="https://github.com/andywarduk/BBCKeyboard" target="_blank">Andy's GitHub</a> that he has kindly made available.<br />
<br />
Of course one of my rules about this blog is that I must have built or made the blogpost myself, this is where Andy asked me to make an interface from his design. So this happily qualifies :-)<br />
<br />
The whole keyboard works a treat, he can even cycle the three LED indicators while using it.<br />
<br />

<br />
Now the 1.00 Firmware for FIGnition is able to facilitate loading programs via audio!<br />
This allows users to upgrade or file transfer with ease, as compared to loading in blocks of 512 bytes via AVR transfer.<br />
<br />
Well done to Julian Skidmore for continuing to make the FIGnition a fun computer to use and learn from.<br />
<br />
In this video I load up 'Crasher' via a Java Application also written by Julian, that converts '.fth' file to audio signals, then demonstrate the same with a recorded '.wav' file.<br />
<br />
<br />
You can read how Julian managed to bootjack the atMega168 for this here...<br />

<div class="separator" style="clear: both; text-align: left;">
I have seen many of <a href="http://www.instructables.com/id/The-Original-Potato-Cannon/" target="_blank">these around the web</a>, and a good friend of mine built one a few years back, so I decided to try my hand at building one, and I thought I should share my method here.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
My design is based on waste pipe components and a gas bbq ignition unit.A tennis ball or large potato is shunted down the barrel. The gas (spray) is squirted for half a second in the chamber and then it is sealed with the inspection cover. The Ignitor combusts the gas and the spud or whatever is projected a long way out of the other end.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
This blog post tells you how I did mine at my own risk, If I get burned, it's my fault. </div>

<div style="text-align: center;">
<br /></div>
<div style="text-align: center;">
The end cap came with an insert, this had a rubber seal on it so I glued the insert into the end cap so the seal was air tight every time, and reducing the chance of leakage.</div>
<div style="text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">

<div class="separator" style="clear: both; text-align: center;">
The side spigot also had an insert with a rubber seal, so I cut a circle out of the insert to allow the ignitor to pass straight through into the chamber.</div>
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-2wgP67lbg7s/U7fWboHJ8aI/AAAAAAAACbI/a9qhOlpGE_o/s1600/100_4455.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-2wgP67lbg7s/U7fWboHJ8aI/AAAAAAAACbI/a9qhOlpGE_o/s1600/100_4455.JPG" height="239" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
The advantage of using an access pipe boss, is that you have a nice flat surface to mount your ignition unit into, others that use a plain 110mm pip, the unit needed to be seated on a camber or on the end cap.This can result in stress at the end cap or leakage. </div>
<div class="separator" style="clear: both; text-align: center;">
I drilled a 22mm hole for the ignitor then I used a gap filling adhesive to make a good seal at the seat. </div>

Its been a while since I have used my FIGnition Keyboard, I had a spare five minutes to clean it up, one hour later I had all the keys out and cleaned them all with a toothbrush and methylated spirits.</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
I then decided to use some leftover spray paints from <a href="http://retrotext.blogspot.co.uk/2014/04/zx-spectrum-compact.html" target="_blank">sawn-off Spectrum</a> and<a href="http://retrotext.blogspot.co.uk/2012/06/its-complete-post-is-coming-soon.html" target="_blank"> Commodore Pi 314</a></div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
The Grey keys are primed, the F keys up to 11 are gloss red, 12 was forgotten about and the red ran out so its satin black as the unused FIGnition keyset.</div>

Hi, I thought I would try to make a podcast.<br /><br />To keep it super retro It is mastered onto one side of a C20 Tape, the MP3 is infact a recording of the tape!<br /><br />The subject of this episode is 'What is Retro?' there is controversy in it and I would welcome thoughts about it as well as ideas for more episodes in the future.<br /><br />As it is only Ten minutes long it will keep to the point I hope.<br /><br />I am very new to this type of media so, if you have any problem with downloading or my host, I need to know.<div>

<br />
<br />
The SystemA TV Boy was an Atari 2600 style console that cloned 126 Atari Games, It was not at all endorsed By Atari Corp, but still nethertheless was sold by mainstream UK stores up to the early 1990s<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-r5AdsR8CGZQ/U2PTOSaNTfI/AAAAAAAACRY/XD_okWf06no/s1600/100_4319.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-r5AdsR8CGZQ/U2PTOSaNTfI/AAAAAAAACRY/XD_okWf06no/s1600/100_4319.JPG" height="239" width="320" /></a></div>
<br />
My TV Boy is a II the <a href="http://en.wikipedia.org/wiki/TV_Boy" target="_blank">wiki page</a> suggests TV Boy II has no capacity for external joysticks, so only a single player may play using a built-in pad.<div>
<br /></div>
<div>
This was not the case, </div>
<div>
<br /></div>
<div>
I opened my TVboy up to see if there were a way of modding it to composite out as it is RF at the moment, after looking I decided that I did not know enough to try this and there is hardly any info on theses anywhere at all.</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-57O9uUhdAPc/U2PUOREq2iI/AAAAAAAACRg/j-bWnpvpygM/s1600/100_4145_a.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-57O9uUhdAPc/U2PUOREq2iI/AAAAAAAACRg/j-bWnpvpygM/s1600/100_4145_a.png" height="239" width="320" /></a></div>
<div>
<br /></div>
<div>
<br /></div>
<div>
So I was surprised to see that there were solder pads for two joysticks! as the System has a battery cover missing it was not A1 so I decided to get some 90 degree pcb mount d-plug connectors and upgrade it myself.</div>
<div>
<br /></div>
<br />
The mod was very easy, the area needed de-soldering and the new components added, when I had done this I offered up the case to see how much I needed to file and cut for plug access.<br />
<div>
<br /></div>

<div class="separator" style="clear: both; text-align: left;">
The only odd thing was that the fire Button was not mapped to the player one socket, maybe there was a defect in the board, this way overcome by soldering the pink wire from pin 9 to the shoot button on the PCB</div>

The recess looks quite large, but this was to allow the plug to fit in to the case.</div>

My latest project is something I have always wanted to try, I have a ZX Spectrum +2A with Divide interface.</div>
<div class="separator" style="clear: both; text-align: left;">
I have no need for the Tape deck, and I am not ashamed to admit that I always thought the deck added by Amstrad was rather ugly, the new owners of the Sinclair brand bolted stuff to things on all their products.</div>
<div class="separator" style="clear: both; text-align: left;">
The Computer itself was purchased online as a non-worker in need of some repair, so I got it going and used it as is. </div>
<div class="separator" style="clear: both; text-align: left;">
I saw this blog last year describing how <a href="http://oldmachinery.blogspot.co.uk/2012/10/sinclair-spectrum-128-2-mini-part-ii.html" target="_blank">this Blogger had sawn off a +2</a> and I was very impressed. </div>
<div class="separator" style="clear: both; text-align: left;">
My +2A has more breakout ports than the original, the printer port on the PCB is in fact wider than the cut down size so this has to be sacrificed.</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-X6Y9aq3_3r8/U1O7Xx6qGDI/AAAAAAAACOA/DG_EDv1BQkk/s1600/100_4282.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-X6Y9aq3_3r8/U1O7Xx6qGDI/AAAAAAAACOA/DG_EDv1BQkk/s1600/100_4282.JPG" height="239" width="320" /></a></div>

I used a Hacksaw and clamped a straight edge to cut away the far edge, this will be needed to cap off the cut that removes the tape deck.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-GNlJJsTKds8/U1O7XmNOiVI/AAAAAAAACN8/fcvK17HNmu4/s1600/100_4285.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-GNlJJsTKds8/U1O7XmNOiVI/AAAAAAAACN8/fcvK17HNmu4/s1600/100_4285.JPG" height="239" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: left;">
With some filing and sanding, I clamped the edges together and bonded with compound adhesive.</div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://1.bp.blogspot.com/-T5nDa3LsGM4/U1O7lXGAqPI/AAAAAAAACOg/jUQdCgLd8nk/s1600/100_4288.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://1.bp.blogspot.com/-T5nDa3LsGM4/U1O7lXGAqPI/AAAAAAAACOg/jUQdCgLd8nk/s1600/100_4288.JPG" height="239" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
The bottom half was bonded with Grip fill, it served to fill the edges that did not meet.<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="http://4.bp.blogspot.com/-DikAnXzQOg8/U1O7i2SGM0I/AAAAAAAACOU/vr-QWk6-aZE/s1600/100_4286.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://4.bp.blogspot.com/-DikAnXzQOg8/U1O7i2SGM0I/AAAAAAAACOU/vr-QWk6-aZE/s1600/100_4286.JPG" height="239" width="320" /></a></div>
<div class="separator" style="clear: both; text-align: center;">
<br /></div>
Filling and sanding to hide the edge as best as I could, I then sanded the whole unit with P600 glass paper and washed the unit down with Methylated spirits to get years of furniture polish from it. If this was not done you would get an effect called fish eye, its somthing to do with silicon in the polish not bonding to the spray paint.<br />
