MicroFAN (Part 2)

Part 1, 2, 3 Let’s talk about some basic electronics. MicroFAN is really easy and requires few affordable electronic components: a 12V fan, Arduino (Uno, Nano, etc.), a 8×2 LCD (a 16×2 LCD will do the job too), a rotary encoder, typically a 30 pulse 15 detents per round (so as to say 1 cycle per […]

Music has always been part of my life. And the means to listen to music has been a long way. From the 3 transistors amplifier taken from a broken toy record player to the A&R Cambridge amplifier. From the early shoe box home made speaker covered with wood looking adhesive up to the Magneplanar speakers. So that […]

Incremental rotary encoders (Part 9)

Part 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 Next diagrams show the signal patterns from the A and B switches. The “d” sign shows the rest position of the encoder after a detent (so as to say a click). As mentioned above, the diagrams deal with rotary encoders featuring one cycle per detent. Under the phase plots are the […]

MicroFAN (Part 1)

Part 1, 2, 3 We gained quite a lot of experience after printing few kilometers of ABS on our Makerbot 2x. Controlling the temperature inside the cabinet solved a lot of problems. After few attempts, we decided to modify the printer by adding a fan on top of the transparent cover. The fan is turned […]

Hacky new year, makyier vœux !

Oops, bubbles of champagne are still burbling in my brain. I wish you good luck and full achievement of your projects in 2016. At the present time, a team of 4 members of HL2 group (The company that I co-funded 3 years ago) is attending the CES in las VEGAS (Hall G, booth 82122) along […]
