    electric bikes?

    I'm telling you they are like fat chicks: loads of fun to ride but you wouldn't want to be seen on one. No shame in my game!

    electric bikes?

    That's terrible, our slicks dont have AC outlets outside and are triple locked and alarmed. You do see a lot of Obama phones plugged into McDonalds outlets. One reason I quit going there..7 years ago and counting.

    electric bikes?

    Now my 9 year old wants one. I got a 500W E-lawmower motor and a 7/84 sprocket set off a race cart and his old 16" BMX bike....Hmmm? I kinda like that traction motor that hangs off the seat design.

    Dyson alien fan...

    The i button on the remote toggles through a bunch of particulate readings (NOx, CO, humidity, pollen!) for free, this thing rocks! We had it in our bedroom last night running in night mode (silent and dimmed display) and the room really did smell fresher. Still wouldnt pay $400 for it. and I...

    Best way to remove moisture and mold in car?

    dessicant really works well, so well that it will dry your hands right out if you dont wash up afterwords with a good bar soap. Moving air is good to prevent mold, Even a little PC fan pulling air through the cab during storage can help alot.

    Dyson alien fan...

    Dyson HP04 Hot + Cool filter fan. the ones that have a big hoop on top with no blades. For $400 this doesn't move alot of air but it does heat, and filter the air through 4 filters, 2 HEPA and 2 charcoal. My neighbor gave it to me instead of throwing it away as the motor was making a bad rattle...

    China tach doesnt work

    Thanks! I got the specs all wrong off memory as I wrote this at work. Its actually a 100MHz (200MHz firmware update) Hantek DSO5102 with 1GSa/s sampling and 200MHz 1-10X probes. . This Hantek has an 'auto set' that seems to get about any wave form to show up on screen in a decent spread...

    China tach doesnt work

    Having a hard time measuring the frequency of my distributor lead to coil negative using a digital o-scope. Rigol 5120 ish 2 channel 1GHz rated scope. I hook up the lead to the negative side coil expecting to see a 40 Hz 12v square wave of the distributor sending the 12v to ground but I just...

    China tach doesnt work

    So do you think a genuine Autotecnica would have worked? This one literally sensed the RPMs then it dropped to zero when the motor was still running. Curiously, my dwell meter does the same thing, it senses the RPMs then drops, then pickes them up again in very short spurts but is not stable. My...

    China tach doesnt work

    it even had the Autotecnica logo in the face but it didnt light up when operating. I think it was a QC reject that got rebranded.

    Shout out to Australia! Maybe if I bought it there for $80 AUS it would have worked...Autotecnica Australia

    China tach doesnt work

    Its in the trash. I kinda destroyed the case opening it as my curiosity got the better of me. I sent a 12v square wave in and probed the path and I got it all the way down to the NPN collector and then out the base. IT still didnt pick up the pulse off the coil negative so I bypassed all the...

    China tach doesnt work

    Found a zener diode that measured 13k both ways! It's a W8 so it's a 5.1v so I'll try and replace if I can find one. Is the voltage that critical? Kinda makes sense as I injected my square wave after this diode (seems to be part of the conditioning/protection chain: 2 diodes, 3 resistors and 3...

    China tach doesnt work

    yes the big chip is only the LCD driver. That little L6 is a 400-600 gain NPN. I can inject a square wave into the Base and pick up a reading.

    China tach doesnt work

    What do you suppose J6 (L6 on component) is? I actually get a reading when I touch the signal generator to this top leg and i trace it back to a via to a 10k resistor.

    China tach doesnt work

    Oh and I sent it a (12.4 peak to peak ) square wave out of a signal generator and nothing at 418Hz, or 100 rpm....

    China tach doesnt work

    Ha, no **** right? New "Autotecnica" digital tachometer with digital and lcd sweep readout. Kinda cool for $16 shipped, only to use it to set idle speed on a non tach equipped 2.0 82 Mazda from under the hood. 3 wires : hot, ground, and signal to - slide of coil. So far as good. I hooked it up...

    Equus 3042 analyzer question

    Tried it again today and the tach feature now is totally fubar. It wanders aimlessly every 4 seconds like a capacitor is charging then dropping. It looks pretty simple inside. 2 electrolytic capacitors, 4 mylar caps, 3 chips, 1 transistor and some resistors.

    heated up vent, nothing there but some burnt styrafoam! :-( its all back together. fridge is holding at 40F. I guess its working again. Id like it 34 like the beer cooler at the liquor store!

    shop refrigerator operation

    I'm leaning on the blocked vent theory. I'll torch it and see if anything drips out. Freezer is ice cold. Your defrost theory is valid: does this just cycle the compressor on a timer ie. 20 hours on 21 minutes off like one mechanical timer states online?

    And of course the thermostat (if bad) is no longer available...and completely sold out everywhere. Could I adapt another? are they similar on operation from one to another (rheostat, sense tube,2 spade connectors..) this one says 10K on it

    I feel the same on Samsing appliances. Seems they are too smart for their own good, ie smart on stupid stuff but dumb about solid engineering. Ill try the heat gun method as I feel there is still some sort of blockage on the freezer control vent. Its actually in kitchen, I just mentioned shop...

    Maytag 21 CF refer with freezer on top wasnt cooling beer enough so I started to investigate. Was cranked up,refer to max and freezer to max with no effect, seemed to be stuck at 50F in the bottom refer portion. I cleaned the lower coils (dusty) and the top coils were lightly coated with frost...

    Briggs and Stratton 5HP motor

    well, here is the thing: I dont know the level of FULL (.6 qts? ) of oil from the floor. Here is a pic: with 2 fillers. How does this H-shaft motor determine how much to fill? The plastic gear is the slinger. Im thinking oil level has to be 1/2 way up so it can still sling oil with all the oil...

    Briggs and Stratton 5HP motor

    can anyone tell me the oil level off the floor of the case in inches or mm when full (off dipstick) ? Im adapting a vertical shaft to run horizontally and need to know approx how much oil I need to cover the oil slinger off the rod cap. I have an oil plug at 2" but I think thats too much?

    nut drivers were still $100-130. I passed on all of them. But did pick up an airless paint sprayer for $5...just needed a good cleaning.

    Swap meet Dewalt and Milwaukee tools

    Swap meets flooded with these new and used battery powered drivers and saws. What gives? Do these get scrapped when defective and returned or what? Some manufacturers say field destroy returns...maybe these get resold or sold by the pound? I must have passed 500 Dewalt 1/4 nut drivers......
