A total of six large machines were built at Manchester University, MU5 was a computer that filled a large room and the heat produced was enough to keep the Computer Science building heated during the Winter. MU6, the last machine, was 75cm x 75cm x 2m and eighty times more powerful.A lot of the work done at Manchester was used in commercial machines manufactured by Ferranti and then ICL. Ferranti are long gone and ICL was eventually absorbed by Fujitsu. Regretably the UK computer idustry is now a shadow of its former self.

content: About a month ago I ordered some 80 various jellybeans in different quantities. Total around $100. I was careful to select mostly parts on sale. Many labeled "until stock exhausted-no returns"; many around/under a cent. One part, a rectangular LED at $0.016 each. There were 36 units left, so I splurgedand got them all. Apparently when they filled the order, they found only 35 and the invoice came with "incomplete" status. I assumed stock gone and that would be the end. It crossed my mind to call and make sure it was cancelled, but forgot. Last Friday I received an email/invoice for the missing $0.016 LED, as previously paid. Today it arrived in a big envelope.Now I have all 36 of them

So I had to make a new list before I could order anything.

content: I have two points to discuss one is regarding importance of programming skills for electronic engineer. The other one is developing skills outside your regular Job.In today's Industrial Environemnt,the trend in electronics field is more towards software and less in hardware.In the 70s,80s electronics was 100% hardware.Now its becoming more of software and less hardware.As per expert advice it is very difficult to master both hardware and software.So as a electronic engineer how should we balanced out skills so that we are up to date ?Since I am working in a electronics industry (10 year exp) .Our bosses does not like to share his Knowledge and skills with us for eg. when there is a new project the project manager keeps us away from the design aspect ,programming etc. What he gives us is to find components or some sort of documentation etc..So because of this we can't progress .One of the way I am dealing with this situation is to self learn . Buy a kit do small programming etc.I hope this approach is good enough any other suggestion will be welcome.Kindly advice please .

content: I have a stereo remote control whose volume keypads worn out and needs fixing. Basically the silicone membrane is no longer conductive enough to activate the remote control.I have tried using carbon based conductive glue paint with moderate success, but it eventually the paint hardens and starts flaking off.Got any other solutions that is long lasting and is proven to be effective?Buying a new remote is basically out of the question.

content: If you were so inclined you could duplicate the keypad with proper tactile switches and replace the whole thing that way, another one may be to find some of the small membrane style ones with the metal cap, and see if you could graft that in on top of the old one using some wire wrap wire to the appropriate connections, I'm not sure if they have SMD versions of those, I'm pretty sure they do though.

content: Epoxy fails with time and use. Use some electronics grade silicone ( the membrane is silicone anyway along with the back of the donor button) after wiping clean with a ear bud dipped in acetone ( only the actual area, not the whole thing, it will dissolve the silicone slightly) and then a thin film or drop applied using a match end.Switches are often not usable as there is only a carbon pad anyway with no copper traces. If you are lucky there will be copper pads by the switch position for the thin switch, but you really have to be lucky.

content: Interesting tips so far, but I'd rather opt for a method that is as little destructive as possible.I've tried other things like super-gluing metal foil onto the silicone membrane, but that didn't last long either. It seems like adhesion is the biggest issue. It's a bitch to glue/paint anything onto silicone.Quote from: wilfred on March 19, 2016, 08:25:00 amQuite sure. Everything was washed with detergent+water, etc. I measured the resistance of the pad. It was in the mega ohm range; quite high compared to other pads, which were in the kilo ohm range.

Scott and ones like him specialize in NOS parts to aerospace companies that NEED those parts and are willing to PAY for them. You are right, MANY of the online companies are very shady. They don't carry anything they just wait for Request for a Quote and then go price the item(s) from the real dealers and add 100% markup for themselves. There is a private online network for people looking for, and selling HIGH quality, NOS parts but you have to subscribe to it. I know Scott has his inventory list available via it but if you're serious and are willing to pay the cost then give him a call.

The first part is just historical background, but they get into a lot of nice (and at the time innovative) technical fiddly bits on the operation and design of the AGC.As for my favorite bug: The AGC on the LM was programmed to interpret a certain signal from the landing radar that it had landed. Apparently there are just 3 craters on the moon that are shaped in a way that radar reflecting off of them would fool the LM's AGC into thinking it had landed, andshut off the engineprematurely.There's a couple spots where the presenter misspeaks (I know: astonishing that such a thing could happen during a live presentation), but generally a really nice talk if the subject appeals to you.

Both have a 24-hour supply and a night supply circuit.Just realized that a few days ago another electrician swapped one of those night storage heaters at my neighbors apartment to a modern single phase IR heater.Since there was only one three phase cable for that room and the next, the electrician just cut two phases, switched the remaing one to the 24 hour supply and left.Now my neighbor has one unheated room.And since the ONE fusebox for the whole house is in my apartment, i'll have to spend another day at home next week, watching yet another guy untangle that unholy mess.Sent from my STV100-4 using Tapatalk

content: Quote from: station240 on March 18, 2016, 01:52:28 pmI think modern breakers, when in doubt, rather take themselfs out then letting spikes through.The old fuses are rather lazy in comparison. Depending on age and manufacturing tolerances and ambient temparatures, they can take anywhere from a tenth of a second to a few seconds to blow.And there is always the light risk of electrocution in this screw-in type fuses. The ceramic insulation is prone to shattering and spalling over time. Not to mention that the fuses themselves can get scalding hot in some circumstances (for example, if you pull 17 amps over a 16 amp fuse, it may hold up for 15, 20 minutes with a red hot glowing wire inside before burning through). Had that happen to me before.

This was the main market for rubidium clocks before the cellular basestation market exploded. The PSTN is clocked from rubidium sources. TV and radio stations clock from rubidium sources. When streams need to be switched and mixed there is never a need to rate adapt them.

An awful lot of sites use Cloudflare and all they will see is an awful lot of connections from the VPNs IP pool so suspect bots. TBH actually using a recaptcha is good, a lot of hosts would used to just drop all connections from those IPs for a while. Sometimes that lead to whole towns or even countries been blocked from certain sites due to one or two arsehats, especially in the days of dial up or early broadband.

It's literally just a standard astable on a bit of stripboard with some screw terminals on one end. There is a trimmer to control the frequency between about 1 and 20Hz and an LED driven by a transistor on the output so not to load it too heavily so you can see what it is doing. Drives CMOS and TTL fine. Doesn't need a box.Also a canned linear regulator board (LM317) with a multi turn trimmer you can use to get another voltage when you run out of bench PSU holes.Logic probe. I've got two of these. One is a voltage sensor (common emitter amp) built into a Bic biro for red/green testing just for convenience. The other one is a slightly more elaborate one based on a 4001 for buffering and a monostable pulse stretcher. That can detect hi, low, pulsing stages.High voltage probe. Bunch of 10M resistors inside a Bic again. Basically a big voltage divider.All of these are an hour or two to put together.
