PIC16F818 overkill. - Page 1

timestamp: May 01, 2017, 08:39:17 am
content: So my wifes 5 year old but hardly used bath lift chair which only gets used when we have to stay in a hotel control box with built in battery failed to charge. Cannot get a new one as Manger who make it have changed the model and no longer service this one. I cracked the unit open (it was completely sealed with epoxy) and found 12 AA size NiMi batteries and a small circuit board. The power to the motor is directly controlled by two micro switches which give up and down on the chair. On the board is a PIC 16F818 which controls the battery charging that is all it does as the motor reversal is done by the micro switches which take the full current draw.This seems rather an overkill to me. I have now replaced the complete control box with one I made using just a two pole two way momentary switch which connects to a small lead acid battery.

I charge them that is the ones outside of the wheel chair with a commercial leak proof lead acid battery charger. I use the old wheel chair batteries for all sorts of things, they work quite happily in a car even, nothing wrong with them other than the wheel chair goes into emergency shut down when the motors start and the internal resistance of the cells has gone up a tad, as I said before 0.75 volt drop measured with 35 amp draw when the motors start.

content: That 'assistance' stuff is over engineered but it's done to meet quite stringent regulations which are meant ot ensure that the equipment is safe and won't harm the user.You can't for instance call an amplfied microphone with earpiece a hearing aid as that, in the UK, has legal connotations which imply a level of certification and testing, there are similar legal things around mobility scooters and wheelchairs, you can buy a shopping scooter and a wheeled chair far cheaper than a mobility scooter and a wheelchair.I'd be concerned that the PIC was sensing stall current as well as controlling charge and possibly monitoring charge level but your solution sounds adequate if you're the only person using it

With that you can process perhaps a few GPM.Although of course you can't get small tubes like these LEDs.I'm surprised if it can do 2-3 LPM, thats impressive if its a realistic number.

content: Don't really know them, but I had a look at the brochure for the RT series UPS and I am confused. They claim it is an online double conversion UPS, and yet they say when not running on battery, the efficiency is 98% (ECO mode). When running on battery, it is 87%.http://powershield.com.au/wp-content/uploads/Brochures/Centurion_RT_Print_31032016.pdfJust doesn't make sense to me. It sounds like it is a standby UPS of some sort. If they have built a true online UPS and then offer an eco mode that turns it into a very expensive standby UPS, it sounds like a very odd decision to me. No way do they have a double conversion system with 98% efficiency.The key principal on an online UPS is that the output is always coming from the inverter (unless an overload or inverter failure sends it to bypass), so what happens on the mains has absolutely no effect on the output waveform.There is a huge difference in the design decisions between a standby UPS and an online UPS. The online UPS has to be designed for many thousand of hours of constant inverter use. A standby UPS may in its life have the inverter running a handful of hours.If you find out anything, let us know. Particularly if they have done something brilliant.

I can find mg90S (the S at the end) and it should have metal gears. but what about mg90 without the 'S'? is that important? they are all pwm-based servos, right? some vendors mark one as 'digital' and the other as 'analog' but I'm not sure if they are at all different. or, is this the internal circuitry? from the outside, its still simple pwm to control them, right?finally, since there are SO MANY fakes out there; who is a good seller to buy from? which brands (tower pro?) should I buy? I see so many reports of junk being sold, I'd rather not waste time on junk.

content: The Analog/Digital servo thing is to do with the rate the PWM signals can be sent to the servoOriginally, the standard rate for RC was 50Hz, however since the advent of transistors (!) more modern electronics can accept much higher rates and these are so-called 'Digital' onesWith the higher rate, the servo will react slightly quicker - good for drones (Tri-copters)As for the 'S' suffix, can't sayHobbyKing is the obvious place to buy from but alot of choiceThere's also US basedServo CityMost cheap servos use brushed motors, but the better ones can use brushless motors which will wear lessI have had TowerPro servos myself but couldn't really say if they're any better than other brands TBH !HTH

content: MG90 and MG90S differ mostly by speed. Supposedly slightly different types of bearings - even the RC sites are rather vague because the Tower data sheets also are. I wouldn't mix them, but either should be fine for this use. Much better than the plastic geared SG90. You can USUALLY tell the fakes as they won't say Tower Pro on the label.

( it didnt used to do that when I bought it)Similarly when I use my laptop on sockets without grounding, it gives me tingling sensation.My cousin has a gaming computer,full metal chassis, all of it gave you shock making it a torture to use,until he got his house electricity grounded.I thought to myself,how could it be that these reputable companies (sony,lenovo,corsair) can design such stuff?all of these devices seems to be leaking out 70-80 volts in referance to earth, and giving out 3-4 microampswhat could be the reason?unfortunatly the warrienty is intact,otherwise I would have done a teardown

content: Edit:This is an April Fools post and a lot of wishful thinking.Intel just announced the Xeon Arria processors with built-in FPGA matrix for high-performance computing systems. The Xeon Arria processors combines a Skylake processor and Arria 10 FPGA matrix on the same die, allowing even higher performance for parallel computing than the Xeon Phi many integrated cores platform can fathom. The Xeon Arria processors comes in two series: Xeon Arria A3-1200v5 based on Skylake-WS, and Xeon Arria A5-2600v5 based on the yet-to-be-released Skylake-EP. The former comes in the LGA1151 package and can work with a motherboard with Intel C232 or C236 chipset; while the latter comes in the LGA3647 package and can work with an Intel C630-series chipset. Prices of the devices are yet to be announced. A developer-oriented Core Arria A7-6700P is also announced, which is similar to a Xeon A3-1200v5 but can operate on Intel 100-series desktop chipset.

Now I guess it'll be two or three motherboards with a Core Arria A7, a Ryzen, and maybe the Broadwell still. Each one will be a separate computer, but they will share their OS and applications running on them, as well as sharing the graphics cards.

Basically a live updating roll function on the Saleae interface it what I am looking at As its intended use is to see large scale timings, having precise timings is not necessary.Saleae if you are reading this, this would be a sweet feature, even if for lower baud rates <512k.

content: I would post this under "repair" but unfortunately I can't fix it without removing the entire car dashboard (I tried to before to fix a bad dash light circuit and just ended up losing a clip without ever getting the trim off). It's this model from 1999http://www.freshittips.com/images/images.gtcarlot.com/pictures/5418441.jpgI've noticed it has severe trouble staying on one FM station, it is extremely susceptible to neighboring station interference when the station gets weak, which I find strange for a digital tuned radio. Is this normal? I mean the stations are .2MHz appart! It's not like an overlap either, it's like it's trying to tune a nearby station every few seconds (usually the one below it too) when it gets weak, making awful bad CB noises. I have an all valve stereo and it doesn't do that, it just goes to static when it looses the station. My only guess is that, given it's 1999, it's some sort of analog superhet with digital pots controlling varactor tuners (AM and FM) and either simple DAC monitoring of the AVC and AFC or those are also analog. So if some of the filters and oscillators have gone misaligned and too wide, it will keep detecting the other stations and trying to lock on to them.

You probably can get an aftermarket mounting fascia that will allow a more common DIN or double DIN radio to mount in place of it though.

My thought was perhaps I must demonstrate that I still am knowledgeable in the industry. So I have been looking into getting some sort of certifications. What pops up on the search engines is ISCET, Certified Electronics Technician. There appears to be levels of certification i.e. Associate to Journeyman. Is anyone familiar with these Certs? Do they carry any weight with employers. Would obtaining the CET be worth the time and money? Any other suggestions?Thank You
