Highly Learnable Open Hardware, Open Hardware Summit 2010

  1. 1. Highly Learnable Open Hardware Michael Shiloh Teach Me To Make michael@teachmetomake.com My name is Michael Shiloh. I'm a tinkerer and teacher, interested in teaching by building. Together with my partner we run a teaching organization called "teach me to make"
  2. 2. Highly Learnable Open Hardware I'm a co-founder of makingthings just one of many computer interface things all trying to do what arduino finally did right
  3. 3. Highly Learnable Open Hardware my main interest is in teachingelectronics using tinkering and contraption building. I've worked with adults
  4. 4. Highly Learnable Open Hardware As well as children
  5. 5. Highly Learnable Open Hardware We like using common household objects * everything exposed * extremely low cost * can be duplicated with salvaged components Important because 1. seem to demystify science when objects are familiar 2. allow duplication We are extremely committed to allowing others to reproduce what they learn with us without having to buy any special parts
  6. 6. Highly Learnable Open Hardware For instance, here is a left and right controls for an RC vehicle using clothespins
  7. 7. Highly Learnable Open Hardware And here is a vehicle constructed with Popsickle sticks
  8. 8. Highly Learnable Open Hardware We use the same philosophy when we developed our Arduino robotic project we've had really good results with almost everything we've done, but there is one thing that consistently seems to be a stumbling block for many newcomers.
  9. 9. Highly Learnable Open Hardware since our goal is to inspire in newbies some of the excitement and passion we havefor tinkering and electronics, it really bothers us that this turns so many people away
  10. 10. Highly Learnable Open Hardware What to do
  11. 11. Highly Learnable Open Hardware for simple circuits i don't use any form of breadboarding i want students to understand the importance and feel of a good solid mechanical and electrical connection
  12. 12. Highly Learnable Open Hardware even further, when possible i make them cut ans strip their own jumpers. again, it demystifies the process (there is nothing magical about a connector on the end) and gives them the skill and understanding to use any scrap cable for their own projects
  13. 13. Highly Learnable Open Hardware this is a great first project, hard to get wrong, great lesson in series circuits and good connections
  14. 14. Highly Learnable Open Hardware how much more obvious is this parallel circuit? you can go quite far twisting wires together, but newbies are usually less aware than we are of short circuit potentials but what to do about more complex circuits?
  15. 15. Highly Learnable Open Hardware i've always loved old radios
  16. 16. Highly Learnable Open Hardware easy to see what's going on, easy to follow circuit inspires the sense of "I could do that" How many of you know that this is where the word breadboard comes from? It's in this picture
  17. 17. Highly Learnable Open Hardware Here is a typical arduino LED project
  18. 18. Highly Learnable Open Hardware typical arduino sensor
  19. 19. Highly Learnable Open Hardware and here's the same thing on a block of wood. so i tried this at one of my classes
  20. 20. Highly Learnable Open Hardware they loved it
  21. 21. Highly Learnable Open Hardware
  22. 22. Highly Learnable Open Hardware here is an arduino implemented on a solderless breadboard ...
  23. 23. … as used on one of our coffeebots. can this be done on wood?
  24. 24. Highly Learnable Open Hardware I did cheat and use a perf board to connect to the chip, but this could be avoided as well
  25. 25. Highly Learnable Open Hardware Power supply
  26. 26. Highly Learnable Open Hardware crystal
  27. 27. Highly Learnable Open Hardware An entire arduino on a piece of wood
  28. 28. Highly Learnable Open Hardware A problem: pin spacing is too small for most nails, and tiny brads are hard to work with I'm open to suggestions
  29. 29. Highly Learnable Open Hardware Michael Shiloh Teach Me To Make michael@teachmetomake.com Thanks!
