In my application the Venus 2000 receiver needs some sort of device to hold it in the proper position. Since I want the operator to be able to pay as much or as little attention to the scene as He/She wishes, I want the receiver to keep the penis captured with little or no adjustments needed after the initial setup. In addition, I want the holder to be designed such that the bottom, has little or no ability to change the nature or amount of stimulation received. After experimenting with several different designs, I settled on a simple guide system using gravity as the only downward force. The receiver is light enough, that the air pressure can easily overcome the receiver's weight, but I have found that just a bit of downward pressure is needed to keep everything in place. I also feel that positioning the receiver in a vertical direction yields the best results for most bottoms.
Wooden Receiver Stand
The image below is of a wooden stand. The stand is constructed from 5 pieces of hard wood, screwed and glued at the interconnections. The receiver simply floats in a large hole drilled thru the top horizontal section. This style works well, particularly if the Venus is used on a bottom secured to a soft surface like a bed. In such a case, the bottom's weight will disturb the bed's surface, IE it will no longer be completely flat. The two horizontal "feet" help keep the receive vertical even when resting on an uneven surface. The vertical supports are built wide enough so the bottom can be tied spread eagle, unfortunately, this width makes this stand too wide for the BDGsales table.

Metal Stand
The stand shown below was made from a couple of parts usually used in a chemistry lab, the base and metal rod. The holder is made from some delrin material cut and shaped as needed. Since there are two guide rings, this stand holds the receiver better than the wooden stand above. In addition, the metal stand is adjustable for height. However this design only works well on flat surfaces. The Controlled Sensation table from BDGsales is flat enough for this stand.

If you look closely, you can see that I have added a bit of electronics to the metal stand. This consists of 4 opto-reflector devices and a small amplifying PC board. The purpose of this circuitry, is to measure the position and movement of the receiver. This addition is part of the third generation Venus interface logic, and is not yet completed. Once done, I expect to be able to create some sensing that the computer software will be able to use, so that the bottom can be kept "on the edge" automatically for long periods of time.
For those of you with an electronics background, click here to see the schematic of the circuitry mounted in the metal stand above.
Third Generation Stand
The creation of the CS-2000 interface box encouraged me to make some further improvements in the receiver stand. I wanted the receiver to move in a smoother way with less side to side and tilting motions. In addition, I wanted the CS-2000 to be able to monitor the up and down movements of the receiver. Finally, I wanted to increase the length of stroke available. The pictures below show the changes made to accomplish these goals.

Three lengths of brass square tubing have been attached to the receiver itself, using double sided foam tape. These guide the receiver to stop it from twisting. The holder has been modified by adding three half circle cutouts for the tubing to ride within. In addition, the top guide has had a section cut out of it, so that the receiver can travel lower. This adds more than an inch of additional movement. You can also see that the receiver has been adorned with an optical target for the photo cells to detect. Using the photo cells and the target, the electronics within the CS-2000 can detect the receiver position to an accuracy of 1/10 of an inch.
