Hi, fellow pneumatics fans Ever since the RCX Controlled Air Compressor Tester was posted, there have been many suggestions for it's improvement, in particular to linearize the tracing. More importantly, several people have commented that it was, (...) (24 years ago, 10-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta) !

(...) Nice work as ever! One type of pump I've not seen you test yet is a varation of Michael Powell's using an 8 tooth gear onto 40 tooth gear reduction rather than the belt drive, as this seems to improve performance significantly. How about a (...) (24 years ago, 10-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta)

(...) I don't know how or why but I don't seem to have come across it. I guess I could try to build one but it'll help if you could give me a link or reference to it. (...) Well, I can have a go at it. But really, with this pressure sensor thing, (...) (24 years ago, 10-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta)

(...) Sure - I made a rather ugly version of it including limit switch for my skid steer loader model. There is a picture here; I don't actually think many modifications other than replacing the small and large pully with 8 and 40 tooth gears were (...)

With all this talk of pneumatics going on, I feel I must inform you that all my current and pending creations hardly use pneumatics at all, I've binned them in favour of something more suited to my needs. I'd love to tell you but you'll have to wait (...) (24 years ago, 10-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta)

(...) Thanks, Jen. I'll have a go at it. (...) Well, I was just thinking to what extent you could take the pressure sensor device. Actually, most of my own creations don't use the RCX. And they're mostly powered by the manually operated hand pump. (24 years ago, 10-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta)

(...) Those pressure switches look quite neat! It's one step closer to the establishment of a link between the pneumatic system and the RCX... BTW I was just browsing your website (really great site BTW) and had a question...do you know what type of (...)

(...) Well, the markings say "TIRE PRESSURE GAUGE" at the top and "TRU-FLATE" at the bottom. It reads to 60 psi. No other markings to indicate its manufacture. It came courtesy of John Barnes together with the pressure sensor. The inlet has been (...) (24 years ago, 11-Apr-01, to lugnet.robotics, lugnet.technic, lugnet.build, lugnet.dacta)

TRU-FLATE tire pressure guages are made by Stant. If you search the Web for "Tru-Flate" you will find several stores that sell them. I have been using a digital tire guage (like the one originally suggested on Soh Chio's site) up until now to (...)

(...) Thanks for the identification of the tire pressure gauge. I reckon the stores will soon be doing a brisk trade in them. But I would hesitate to use the word *calibrate* - the pressure sensor is a far more delicate device than the tire gauge. (...)

I use pneumatics mainly where brute strength is needed rather than smooth motion, such as the raising/lowering mechanism on a crane (although this (...)
