I admire you and your knowledge.After all these years, I was wondering if I may make a new 'avatar' for you? Maybe something fresh and new?I'm sure you are fully capable of doing something easily yourself with just a flick of your fingers, but I would like to suggest a change to your avatar.I recognize your avatar everywhere I see it so I know it is something from you, but I honestly feel that you are about due for a fresh new look, especially with how great of a following that you have now.Dave, If you are fine with how you have things then I am cool with it too. I only suggest this because I have seen the same avatar for so many years and it really does not solidify the epicness that you are.I hope I am not stepping on any toes. Like I said, I respect you greatly.Thank you for taking the time to read my opinion.P.S. I look forward to every next video. You have helped me more than my professor.

Electric Vehicles - not Zoom Zoom, but broom broom ... the Sinclair C5 - Page 1
Forum section: electronics / general

author: amspire
author_rank: Super Contributor
timestamp: February 17, 2012, 01:01:18 pm
content: Clive Sinclair was totally brilliant, but unfortunately his judgement was always a little off.The C5 was just a disaster - two slow and dangerous to ever use on the road. The idea of a super lightweight electric vehicle that can move a single passenger with a tiny fraction of the energy of a car does make good intellectual sense, but the C5 and roads full of cars and trucks just did not mix.Where I saw his brilliance was in designs like the ZX80. It had something like 2K of ROM and in that program space, Sinclair fitted a full basic interpreter, a full software driven video display generator (the ZX80 used the Z80 dynamic RAM refresh counters connected to some resistors to make the video D/A, so no video display IC's were used at all), cassette tape data I/O, and probably a few other things I have forgotten. I have never seen anyone who could fit so much functionality in so little code and hardware. His first miniature scientific calculator was programmed on a TI chip designed for a standard basic calculator. In the same memory space that others fitted + - * / and square root functionality, Sinclair implemented Logs and Trig as well.Richard.

A 12" driver needs to move something like 2" to produce a usable 20Hz waveform. Make it a 6" driver and it needs to move 4" for example for the same sound pressure. Make it 3" and it needs to move 8". There really is no substitute for diameter in a "subwoofer"Edit: Big fail on my part. That should be 8" travel for the 6" and 32" travel for the 3" driver.

Also, I keep reading that the front-end to the device can be damaged if your input signal is too large; I'm not farmiliar with the dbm scale, but what kind of RMS voltage (sine wave) and DC offset can you have on those things?

Parametric search on RS or Element14 is hopeless, due to the inconsistent categorisation of switches.Does anyone know of any model numbers for switches suiting these criteria? OR other nice momentary switches you know of, that are good for navigating a user interface on a project? A 3mm tactile switch is far too small to be ergonomic.The reason I'm going for right-angled is that my project also has an LCD screen and a rotary encoder, and it's much easier to align the heights of everything to poke through the case if the LCD goes through the lid, and the encoder/switches poke through the front of the case (shifted back from the edge of the PCB such that they align nicely).Any help would be much appreciated.

content: An alternative, if it helps, would be mec's multimec 3C, 3E and 3F series which have right-angle mounting versions and a wide selection of cap styles and illumination options (although the more esoteric options might be trickier to get hold of!).Afraid when it comes to the Tyco FSM10 switches like the one you've found I've only ever used them bare, so don't know what caps would be suitable. element14/Farnell seem to stock three Tyco keycaps but none of them are listed as for use with that range; further details seem to be a bit tricky to track down on the TE website, apart from that the 'real' part number for the FSM104 switch is 1437565-6. Good luck in your hunt!

content: Thanks, yeah I ended up spending all day yesterday searching around online. Unfortunately, none of the multimec 3Fs and so forth would suit. As for the FSM104, I couldn't find any caps anywhere on the web. :/I ended up going back to the vertical idea, and found a rotary encoder that would match my LCD+headers height, and some tall pushbuttons that I will mount directly on the PCB too, so it will all poke through holes in the lid of the case, with no offboard wiring (thank god!). Only disadvantage is that push buttons will be a bit spongy, when I wanted clicky buttons. Ah well.

content: I have washed circuit boards in alcohol to remove grease or water and such without any problems. I have used benzine as well (lighter petrol) it is things like paint thinners and acetone that dissolve plastics. I keep a bottle of denatured alcohol handy just in case of spillages onto keyboards etc, I have found that if water or such is diluted fast enough very often no damage is done. I first learnt this trick with old televisions which would often cease working due to dust accumulation, I found the best way to remove sticky dust was to wash the boards in warm water and washing up liquid then I would rinse in alcohol to remove the water before drying in a warm place.

I kept getting this feeling that the professor was pushing some preconceived doomsayer agenda, viz. engineers are the root of man-made catastrophic disasters...and yet the main cases that we studied--in particular, Challenger and Firestone; PGP encryption and other topics were discussed, but that's another story--were by and large a consequence of bureaucracy gone afoul and business related decisions, not engineering.
