Professional Design Portfolio - Page 1

content: How are these normally handled / organised?I have a fairly sized list of projects that I've accomplished and I would like to showcase them to potential employers, I'm just unsure of the proper way to go about doing this? The vast majority of my work has been done for my employer so I cannot throw them in a PDF and forward it along. Is the common practice to mention that I have a portfolio to share in the cover letter, and then bring the designs with me if I'm invited to an interview? Or is the only real way to go about doing this is to start a professional blog about individual designs and information not tied to my current employer?

I had always assumed that it was more physical schematic and design documents than oral explanation.Trade-secrets is a big thing I want o make sure I don't violate. It would only prove to bite me in the end if I'm too liberal with it.

content: I'll be in SF in a couple of weeks for a (non-electronics-related) conference, and I may have a half day or so on my own in the middle. I used to work as an engineer in Mountain view, in a prior life, so I thought I'd pop down check out the nerd scene. I was in the area a couple of years ago, but didn't have much time. I did stop by Weird Stuff and Halted, but they were a pale shadow of their former glory. This time, I'm planning on spending at least a couple of hours at the computer history museum. Any other nerd havens I shouldn't miss? Are there any regular electronics-related gatherings? Unfortunately, I will just miss the 1st Saturday sale.Thanks for any heads up!Dave

If you have a squint at the guy's website:http://paillard.claude.free.fr/it gives more details. Basically he was trying to make triodes using the technology that was available 100 years ago. I think he compromised on the turbo molecular vacuum pump but the rest of the supporting technology is also hand made.

I called up a couple of American suppliers, that I have used before and the best price I could get was $9.00 with $12.00 shipping. Then I occurred to me to go to Hakko USA, (sometimes it takes me a while to think of the obvious). Price from Hakko USA, $7.17 with free UPS shipping included. No phone calls, just a one minute PayPal transaction. What a great company. See below link to Hakko USA.

content: Greetings,i have been using the MCP73831 for charging my lithium battery based projects, problem is that i quickly run into heat dissipation issues, when wanting to charge with 500ma, nothing breaks, but the chip heats up, and then throttles the charge current, to around 250mah, im charging from a 6 volts solar panel, and even with a diode to take some of the voltage drop its not perfect.So i started poking around after another charger IC and i found the TP4056, which is a bigger package and looks to have better heat sink capabilities, this lead me tohttp://www.tpmicro.com/China based, "Tapower is a global leader in the design and manufacture of high performance analog ICs (integrated circuits)" , according to their webpageunder their chargers they list the TP8056 switch mode charger ichttp://www.tpmicro.com/goods.php?id=52which looks perfect for my use, it just turns out that i cannot get the part anywhere, no luck in findchips. nor on ebay or aliexpress.The datasheet, is also somewhat weird, as there is only one page available out of 19.http://www.tpmicro.com/datasheet/TP8056Ver1.0_preview.pdfand the datasheet is copyright 2010, so it does not look like something that is just released.Is this normal? could it be a product for the home market?And this brings me to the next question, after having spend significant time looking for something similar to the TP8056 part, like for instance the LTC4002, but the problem with the LT parts from my view is that they are expensive in single quantities.So if anyone has a favorite switch mode charger for single cell l 3.7v lithium batteries, 1.5 AMP would be nice and 6 volt input, please sharein the 1 USD. And i tend to prefer the 8 pin or less packages, with leads.-lk

My micro quadcopter build - Page 1
Forum section: electronics / general

author: Kibi
author_rank: Unknown
timestamp: July 28, 2013, 12:50:42 pm
content: Hello all.I recently decided that I ought to build myself a quadcopter for fun. I thought I'd start out small, so I found a design onThingiversethat looked pretty cool. My brother has got a RepRap printer and he kindly printed the parts for me.That process took a little while to complete, so in the meantime I got on with flashing the ESC's. I ordered Turnigy Plush 6A ESC's as per the design.I assumed that they would employ Silicon Labs µC's so instead of forking out for SIL's Toolstick I prepared one of my spare Arduino's to perform the flashing of the SIL chips. The original firmware on most ESC's is no good for multi rotor craft. Usually a power curve is programmed in so that instantaneous power is not applied to the motors which would in turn smash drivetrains. A multi rotor however needs to have the propellors respond instantly in order to maintain it's current attitude. Also, the low battery voltage cutout needs to be removed so that the craft doesn't just fall out of the sky.I soldered a servo lead to the appropriate programming pads on each ESC so as to ease any future upgrades.All went well, and the magic smoke is still safely encapsulated within the components that it should be. I did use a current limited supply when flashing just in case something went wrong.The ESC's are then closed up and the motor leads terminated and insulated.By this time the plastic parts were ready. I started glueing the parts together and realised that there were some slight imperfections which needed to be ironed out. I set up the milling machine to take about 0.5mm off the bottom of the arms in order to bring them all level with one another.Now the motors are glued into position, the ESC's secured to the arms and the power wiring can be routed.Here is the machine pretty much complete, ESC's calibrated and ballpark settings configured on the KK2 which was still running v1.2 at this time because I forgot to update it.I eventually remembered to update the KK2, but I then forgot to remove the propellors.Luckily, nothing went wrong and I still have all of my fingers. The KK2 uses a MEGA324, so my AVRISP mkII is just fine for flashing the new firmware.Now all I have to do is learn to fly

content: Hey everybody,how is it going? I've recently got a robot arm, and a posted a video asking what I should do with it. Somebody said I should donate it to a maker shop. I instantly loved the idea, people who would appreciate such an item would have easy access. Really solid idea, and it got me thinking that no maker shop exists in my community, although we have a strong historical background in the field (home to Alexander Graham Bell). So I was thinking of forming my own, in the public library lots of space, where it might be possible to get more funding and donations and all that stuff. My question is how would you propose the idea? What features could it offer to the public and all of that?And any general advice in creating one would be awesome.And if anyone would like to contribute to the maker shop such as equipment donations I would be greatly appreciative!

Alexander Graham Bell’s presence is extremely well known throughout the regional area; though it is remembered, I would like to develop an outlet for practical education in field of technology.A makerspace is a community of individuals who come together and actively share lab equipment and collaboratively contribute to each other’s design projects in the fields of science, digital art, and technology. This system allows individuals to develop their ideas in an environment without restrictions. These platforms offer a positive community learning experience.Aside from collaborative efforts, the community would also be able to showcase the practical applications of applied math and sciences. This could ultimately excite and inspire children to actively pursue an educational pathway.In creating a makerspace within the public library would encourage a new horizon of learning for our city. I would like to offer myself in developing this idea, by not only offering my services and skill support but also donating my lab to the library. I am a student currently on my way to becoming an Electrical Engineer and am enthusiastic on developing Brantford’s educational resources and the collaboration between inspired minds.I eagerly look forward to developing this idea, and may be contacted at (519) 770-4259 or a nicolas_john_sek@hotmail.com.Sincerely,Nicolas J.

content: I have come across a pretty old (in recent terms) article from the Dec 15 2000 issue of Science. In it there is shown a method of printing CMOS circuits on a flexible plastic substrate, using ink-jet printing methods. If such a process can be extended into printing InGaN junctions as well (and some sort of resistor), then this can happen. If you connect an arbitrary length of these pixels with serpentine layout then you can get a solid clear plastic sheet with an entire display plane. Stack a bunch of them then you get a solid display cube. I figure you can get 240x350x192 pixels to clock an entire shape display with less than 1GHz rate. Easy these days. Since the flop shown here uses only the parasitic capacitance of the transistors to store the latch state then the clock has a minimum period as well.

Those were all mechanical, a box you needed 2 people to carry ands 4 to put in the bay, all brass plates and gears, with thousands of ball races, generally at least 2 on each shaft, and hundreds of anti backlash gear trains.
