I'd just like to let everyone know that I'm currently not receiving the mailing list, (who knows why!) so could everyone _please_ mail me copies of any responses you make to my mail? The only other way I have to view them is by checking the mailing (...) (28 years ago, 20-Apr-96, to lugnet.robotics.handyboard)

I'm trying to build the h-bridge circuit posted on this list, and, of course, I'm having problems. It simply doesn't work. So, in my efforts to troubleshoot the thing, I'm trying to figure out how each part of the circuit is supposed to work. Which (...) (28 years ago, 20-Apr-96, to lugnet.robotics.handyboard)

This is a repost of a message I sent a few days ago. It bounced back to me, and I don't think it ever made the list... (...) (28 years ago, 19-Apr-96, to lugnet.robotics.handyboard)

| | Re: motor voltages
|
|
An LM317T is probably what you want. It will provide 1A continous or 1.5A with heat sink. Put a large Cap on the output to take care of peak surge requited by the motors when turned on. These temperary heavy current needs will not hurt the (...) (28 years ago, 19-Apr-96, to lugnet.robotics.handyboard)

| | Multiple Servo control ??
|
|
Has anyone looked into using the "Mini SSC (Serial Servo Controller)" with Handy Board? Has anyone written any code to allow HB to SSC comunications? I would be very greatful for any info on combining the HB and SSC. Thank you, Larry ***...*** Larry (...) (28 years ago, 19-Apr-96, to lugnet.robotics.handyboard)

| | Extension Board
|
|
I want an extension board for the HB. I am planning an arm on my bot. Hopefully with 4 or 5 degrees of freedom so I need more servo ports. Are there any beta units available? What is the progress on the production units? Does anyone have any first (...) (28 years ago, 18-Apr-96, to lugnet.robotics.handyboard)

(...) The E1 will work fine. It is officially supported by all of the HB software. See the IC manual for more details. -f (28 years ago, 17-Apr-96, to lugnet.robotics.handyboard)

| | HC11E1 or HC11A1
|

I was planning on using a HC11E1 on the handyboard instead of the HC11A1, other than twice the internal RAM it looks to be the same part. Is there any reason the E1 part won't work? Mark ===...=== Mark Hastings Phone 206-447-4175 Email: (...) (28 years ago, 17-Apr-96, to lugnet.robotics.handyboard)

| | Re: problem with PCI PowerMacs?
|
|
(...) Yup. I use my 7200/75 as my only robot development station, and love it. Not a single problem. As11_ic works great, all beat versions of IC work great, even the older version 2 of IC works great. My handyboard couldn't be happier. (except if (...)
