|
Hello, Does anybody know if it is possible to build a handyboard with more than 32Kb RAM? I do not know the exact details of processor, but if it is a 8-bit processor it should be possible to build a handyboard with a maximum of 256Kb memory! And (...)

(...) Try this software: www.expresspcb.com Though, it doesn't have an auto route function, but this is good for simple pcb design. joema (26 years ago, 26-Feb-99, to lugnet.robotics.handyboard)

Does anyone know of a good but simple to use schematic an PCB design freeware program out there on the net?, I have downloaded a few but they vary complex and hard to learn for the simple board I need to create. I like something with a good (...) (26 years ago, 26-Feb-99, to lugnet.robotics.handyboard)

(...) You should probably ALWAYS assume that any IC is ESD (electro-static discharge) sensitive and take all precautions. Mike (26 years ago, 26-Feb-99, to lugnet.robotics.handyboard)

Has anyone hacked the sonar out of a sonar tape measure? Radio Shack sells sonar tape measures for about $25.00, that's half the price of buying the transducer and sensor together. I mentioned in a previous posting that I am interested in running (...) (26 years ago, 25-Feb-99, to lugnet.robotics.handyboard)

(...) i do not have the Mobile robots inspiration book, but i think if you want to use it in a good way you will have to flash the right led for a time, check for reflection, then switch it of and check if there is also reflection (then it was (...)

I am looking at the Schematic in the HB HP right now. It looks like the 1K resistor is connected to the visible LED. From the schematic, it looks like you can connect a resitor and IR LED in series to the "3-pin female header" to make your (...) (26 years ago, 25-Feb-99, to lugnet.robotics.handyboard)

I had intended the two types of interfaces for different purposes, but, I assume RF does not need line of site work. R/C cars for example can be controlled from several rooms away in my house (worked with one on a telepresence implementation). I (...) (26 years ago, 25-Feb-99, to lugnet.robotics.handyboard)

The software written by Max Davies should allow transmission as well as receiving. The information that I have doesn't include the hardware layout but as far as I understand the 1K resistor in the IR transmission circuit on the board should allow an (...)
