content: Nice interview, I do like CC, especially the electronic edition, and the nice style they have. I subscribed when I saw they offered a digital edition, it worked out to be incredibly good value for money, especially as the local distributor stopped supplying it due to low volumes ( not helped by the price being the cover price multiplied by 50 or more). Plus the editor, Steve Ciarcia, is very interesting, and always a good article.

content: All of these brands have models that resemble the Hakko 936 model.There is also CSI, Quakko and other unbranded units that look alike.You may have heard of one company producing 13 different brands of washing powder for various price sensitive market segments,and so in manufacturing, its common to have assembly lines for branded and unbranded goods of the same physical item.So in the case of the 936, how do these differently branded soldering irons measure up?Anyone have pictures of the insides of the various units mentioned?

timestamp: February 05, 2012, 08:07:15 pm
content: IIRC there have been pictures of the inside of this or similar soldering stations on this site. They were very different inside. The conclusion was there is not only rebranding, but also a lot of cloning going on here, and 936 like soldering stations are manufactured by different companies, instead of one company producing all those variants. However, several of the cloners do have variants of their clones, too.

content: I'm sure a few of you got one of those Rubidium frequency standards, I sure did, well 2 in fact one for messing with and one to use as a master clockon my audio recording gear which just happens to be a 10MHz input. there is actually a master clock on the market that uses a rubidium standard and it costs£10,000 so when I saw the video Dave did I thought for that price I might aswell make my own, I didn't need it to be that precise but at £30 it's cheaper thanthe shit ones on the market.anyway I need a few ideas on making a power supply what can feed the thing the 1.5 amps at 15volts and whatever it was (800mA?) at 5 voltsobviously at the moment I'm powering it with 2 seperate bench power supplies but that's not viable in the studio. so.. any ideas?my first thought was to use something like a LT1084 unless anyone has any better ideas

content: The universal notebook power supplies can usually output 15V at 3+ amps. Or many of the Toshiba and NEC notebook power supplies are a fixed 15V, and you can probably pick up second hand supplies very cheaply.Add a 7805 regulator on a heatsink, and you have the 5V.The peak currents are usually for startup. I would guess the 15V probably drops to at least half once the unit is warm.

My eyes are focused 3 feet away, thus the dust at 1 foot away is really blurry, and looks like smoke. It has nothing to do with my eyes. It's just an illusion, not an issue. It's not a constant thing, it's just when an occasional big piece of dust gets in the right spot to make it blurry enough and big enough.Sorry about the confusion haha.
Prototyping Universal PCBs at good prices - Nice quality  - Page 1

content: I recently purchased some universal prototyping PCBs from China and thought I would share the details here.The double sided boards are nice quality fibreglass with individual 'lands' and are designed for point to point linking aka 'dead bug' style builds. The price seemed very reasonable so I have ended up buying quite a stock which should serve me well in the months aheadI think these will also work well for prototypes using the 'Manhatten style' building technique that uses strips or small 'lands' of PCB material.Nice Manhatten style guides are to be found here:http://www.aoc.nrao.edu/~pharden/hobby/HG-MANHAT2.pdfhttp://www.zianet.com/dhassall/advmanart.pdfhttp://www.k7qo.net/manart.pdfHere is the auction listing for a 'variety pack' but listings are present for sets of specific sizes as well.

I would prefer to get a job as an electronics technician since I love working with electronics and my computer engineering diploma qualifies for C.Tech through OACETT after 2 years experience. The problem I am having is getting my foot in the door. I have been searching for about a month and have not yet gotten an callback. So I thought that you guys could help. So what is it that the hiring manager wants to see on the resume and cover letter for a technician. so far the major selling points on my resume are:-Aforementioned collage experience.-Robotics club.-presidents honour list-hobby electronics.-use of Kicad-use of oscilloscope, DMM, Soldering iron etcI would appreciate any help you guys could give thanks.

content: Dopush the Computer Engineering qualification,as it is a completed Diploma.The 1.5 years of the Electronics subject is obviously of more importance in doing a job in your chosen field ,BUT the HR person who will probably be your first contact has probably never heard of the subject.He probably understands Computers (or thinks he does) so the completed Diploma may be more impressive.I would definitely include the stuff you have listed,except for the practical skills,which are more for the personal interview when you get to it.I would suggest also,that in your first approach,don't mention the reason why you didn't do more than 1.5 years on the Electronics Engineering Technologist course,as although it is probably illegal to do so,they may write you off due to the health issue.Again,tell them everything at the interview.Have you had other jobs,either in the same field,or others?They usually like to know you can hold down a job.If you haven't worked in the field,you are facing competition from people who may be able to offer greater experience & theoretical knowledge.The big problem is that Technician positions are fairly thinly spread,& usually have a lot of applicants.VK6ZGO

An make sure your receipt describes DS1052E and its not some vendor alias. I have not made a warranty claim; just thinking of some ways they Rigol could not honor the warranty claim.

I know sod all about ATMegas. The LCD module is probably a bit rubbish and can't pull down 10k. The processor might have pullups configured which won't help.

Troubleshooting a Tek 2225 scope - Page 1

content: I picked up a Tektronix 2225 the other day for really cheap, but with the caveat that the first channel does not work. Channel 2 appears to work beautifully; I get nice, clean traces of the probe adjust output on the scope, so I know the horizontal sweep and triggering circuits work ok.When I have a probe attached to Channel 1, I get nothing. If I set the coupling switch to GND, I get the flatline trace, but it will not move when I adjust the vertical position potentiometer.Really, I only need one channel for the occasional hobbyist work I do, but it would be nice to be able to repair it and get both channels working.Does anyone have any suggestions as to where the problem is in this scope? A bad vertical preamp or final vertical amplification stage?

The issue was that channel 2 was so far out of cal that it prevented the trigger from working on that channel. You may want to start with the calibration adjustments to see if it helps.

timestamp: January 27, 2012, 09:20:25 pm
content: Yes that should work. You will need to assemble a BNC dongle as illustrated in the manual and in the on-screen instructions. Also, make sure your scope has warmed up before performing the calibration. The scope should be warmed up 20 minutes after power-on. The user calibration will take about twelve minutes to complete on a four-channel scope.Let me know if this works for you.

author: Unknown
author_rank: Unknown
timestamp: January 29, 2012, 02:04:35 pm
content: What did Agilent tech support say about this issue?A factory calibration usually involves hooking the scope up to a scope calibrator and starting the automated MET/CAL procedure. Alternatively you can often manually set the correct values on the calibrator and step the scope through the procedure. The procedures usually require fairly accurate DC voltages (something you could probably do with a decent lab power supply and a good 4.5+ digit DMM), leveled sine wave generators with a good amplitude and frequency accuracy (something less likely to be found in a hobbyist lab) and a pulse generators that generates pulses with a fast rise time (eg. < 1 ns) and low aberrations. Calibration of digital scopes is often much less tolerant of different input signals, while you may be able to adjust the trimmers of an analog scope to a less than perfect signal, a digital scope will usually just refuse calibration if the signal does not fall within fairly tight limits.
