MIT's Rod Brooks papers

What we have today are not Fairly Expensive Tortillas or Fortunately Edible Theremins,  but Field-Effect Transistors. If you know what it is, I will leave you to explore: 1RFZ44N N-Channel FET $2.50 The IRFZ44N is a very powerful useful N-Channel FET, with only 0.0175ohms resistance pushing 20 amperes at 5V! FQP27P06 P-Channel FET $0.95 A […]

Here's something to take a boo at a workshop by Tom Mair and a Grade-5 class. From his message to the BEAM mailing list: Last year I helped Mrs. Corbett's Grade 5 class build robots and we had a blast (see a review here http://www.aasland.com/hcrd.html). Well, this year we are doing it again. We're building […]

Wireless doorbells have a tendency to... suck. I speak from personal experience on such matters. When they fail to get my attention while at home, apathy generally wins out and inevitably forces me to head down to the FedEx/UPS depot to pick up my missed package. David Watson, a man of action, took matters into […]
