How to pay 600 rubles and puzzle over functionality for 1200? Probably everyone knows the way to "upgrade" the cycle computer - put 2 magnets on the wheel and the speed doubles, but we bequeath go the new way. We double the number of functions of the bicycle electronic computer with one movement of a screwdriver.

While operative at VeloDrive Corporation, I often ransacking around in accessories and noticed that for some cycle computers, the descriptor of release, the case and section cells on the show are the same, only the markings and, accordingly, the price differ. For example, the VDO A4 bike computer carries the announced functions:

Current speed (0 - 199.5 km / h).
Distance counter (0 - 999.99 km).
Sum up Distance Counter
Watch (24 hours)

While his older brother, more expensive in the price heel, promises us:

Current hasten (0 - 199.5 km / h).
Distance counter (0 - 999.99 km).
Total Distance Riposte
Clock (24 hour musical mode)
Common speed.
Maximum (elevation) speed.
Trip timekeeper (0 - 23:59:59).
Index of average rate (shows the current speed supra or down the stairs average).

Twice as many features. But, you see, it is profitless for the manufacturer to rivulet two contrary conveyors for the same bike computer models that differ only in the data displayed on the screen and the formulas for their calculation in microcircuits. Therefore, they are riveted on one elemental basis, and a cute Chinese woman (or Thai, or Malaysian) decides to turn an A4 Oregon A8 estimator at the end of assembly packing the innards inside the case.

So, we take the patient from the warehouse and retire to the back way with the camera. For the operation we leave need:

1) A slotted screwdriver widely
2) A cross screwdriver
3) A slotted screwdriver
4) Close-unfreeze adhesive or sealer

First, available the case. It is improve to do this from the edge, there the screwdriver near with confidence enters the groove. Do non be hydrophobic to push it, the body is glued with fervent glue and you bear to break the intrinsic legs-position fixers.

After opening, we see interior the printed circuit board fixed with five screws. We remove the hot spots of hot melt glue around the edges, they Crataegus laevigata interfere in the future to close the incase.

The caring engineer Liao left hand the instructions on the board itself for the lovely girls on the assembly line. From it we see that in order to turn the A4 bike computer into the A8 example, we need to murder the jumper S1 (DEL) and leave the pinafore S0 closed (CLOSE).

It is time to find the jumpers. When removing the screws, be careful, moral can the board is the display and its contact group. I recommend raising the get on past lightly press the "slot" screwdriver in the opening 'tween the undersurface (solitary) screw and the edge of the case, as the plug-in is nonmoving held on by hot glue. There is nothing to wrong on this side of the board.

This is how the add-in looks later on removing the screws. Immediately set aside the housing with the display to the side, removing the remnants of hot melt adhesive.

Board closeup. The jumpers we need are located at the bottom left. Connected older models of whee computers, they were only flooded with solder, now they began to order conductors, for ease of remotion.

This jump shot is removed simply. We put the board on a flat, soft surface, take a slotted screwdriver and, having set the baksheesh on the side of the S, we well run into the end of the screwdriver with your palm. 1-2 strokes and the jumper removed.

Next, we carry out the assembly in the reverse regularise, with kid gloves reduce the screws so that the display contact is established, private the case and coat with hot paste all around.

As you tush see, in addition to the main functions, speed, distance per trip and odometer appeared: travel clip, average and maximum speed, as considerably as an picture screening in a higher place OR downstairs the average speed, we are driving.
All.
