This is the ServoBoss. It is a servo tester capable of driving up to twelve servos simultaneously.
The kit is available from GadgetGangster.com
It currently has eight programs.
Program 1 - Set milliseconds
Adjusts output to twelve servos (two groups of six) in .001 millisecond increments using pushbuttons. Displays pulse-widthsetting on LCD for both groups. The second group is reversed in all programs except for Dead Band.
Program 2 - Adj milliseconds
Using a pot, controls twelve servos while displaying pulse-width on LCD.
Program 3 - Dead Band
Alternately sends two pulses differing by X microseconds. X is adjustable from zero to 99 and is displayed on LCD. Increase the setting until servo jitters, then back down by 1 uS increments to find the Dead Band.
Program 4 - Cycle Servos
Enter High End, then Low End, then number of cycles, transit time and finally, the pause time. If number of cycles is 0 it will run indefinitely. Transit time is adjustable from 20 milliseconds up to 60 seconds. Pause time is adjustable from 0 to 60 seconds - anything under 10 milliseconds is ignored.
Program 5 - Sweep Servos
This program is nearly identical to Cycle Servos except that a button press is required for each stroke.
Program 6 - Set Three
In this program you set three pulse-widths. One each for Low, Center and High. Press one of the three buttons and it sends the servo(s) to the corresponding setting.
Program 7 - RX Input
Connect your RC receiver or other servo signal producing device and read up to six channels. Displays pulse width in 1 uS resolution. The incoming signal is passed on so that you can control your servos while reading the pulse widths.
Program 8 - Battery Pack Test
Displays voltage of battery pack, .01 v resolution, a few hundreths of a volt accuracy. This program always runs at start up. Good for checking for charged packs - just plug it in - no button presses required.

servos.
Thanks,

The ServoBoss can control up to 12 servos simultaneously for testing however it was not designed to control servos that are under a load.
The LCD has 16 pins. Installation of the socket header starts at C 1. However, C 16 is occupied by the 103 cap to the pot. Some resolution is required.
Another possible consideration might have been the mechanical interference posed by the crystal and the adjacent 104 decouplling cap as with the mounting of the 100K ADC, but are resolved by viewing the expanded "original" view.
I've noticed that once in a while it is necessary to reload the page in order to get the mouse over feature to work. You should see a yellow outline around nearly every component, when you put the mouse on it, a text box will appear with an explanation. If you don't see the yellow outlines, try reloading the page.
Where are the readable diagrams in step 3 & 4 of ServoBoss for wiring the back side of the circuit board as above and any other special instructions?
Also before I forget; How would I go about sending you payment data in a secret and secure format? Thanks.
Take care.

Take care and 73
Thanks, JZ
I do not know where the Gadget Gangster Boss boards are made.

I await hearing back from you.

Everything else is complete, it's just the joysticks that we are waiting on.

Did you click on the little "i" in the upper left corner of the picture? That should allow you to select from a variety of image sizes, including the original.
Let me know if that isn't working for you.
I just received the prototype PCBs yesterday. I expect that they will be available next month.
