Ah, home at last. After spending so long in the mechanical world, I almost felt disconnected from my electrical roots (ba-dum-tss). Corny jokes aside, it has been really nice to get to dig through datasheets, lay down some traces, tear through app notes,...
Who is Otto? An interactive robot that anyone can make! What can Otto do? Otto walks, dances, makes sounds and avoids obstacles. Why Is Otto special? Otto is completely open source, Arduino compatible, 3D printable, and with a social impact mission...
Way back in the late 80s, I remember seeing a TV show (I think it was Amazing Stories) which featured an interesting clock. It was round, black, about the same size as a normal wall clock, and all done up in LEDs. The LEDs appeared to be what I now recognize...

Earlier I mocked out some arms to be used with Dynamic Actuators which are about 4" in diameter. There are 2 problems with the arms. Firstly the torso with 4 actuators is a little heavy for dynamic actuators. Secondly, the arms look a little husky. Recently...
Repurposing a PLC clone for use with Arduino It is fairly common to find in online shopping pages, advertising like this: “Industrial control board compatible with FX1N, FX2N, FX3U and programmable with GX software”. The price is attractive,...
In my previous log entry, I had fried my CM4 by shorting 5V to 3.3V, so I had to order a replacement, which arrived last week. The next thing for me to test is whether I can boot the CM4 on my board, so I installed Raspberry Pi OS and set enable_uart=1...

Peeqo - the GIF BotPeeqo is a personal desktop robotic assistant who expresses himself through GIFs. Think of him as the love child of Amazon Echo and a Disney character. He has a conversational UI, so he responds to voice commands but answers only through...
It all began with a big letdown. Back in 2010 when the grass was greener and the blues bluer i decided to stop ruining my eyes and start taking a part in the e-ink revolution. I choose the IREX DR1000S for obvious reasons. The size and the possibility...
Drill (2.5mm or 3/64") and tap (4-40 or 3mm) the screw holes. Obtain 1/2" pan head screws to match. Place the PCB with the transistors on the heat sink and align the TO-220 TAB holes to the tapped heat-sink holes. Melt the solder joint on the transistor...
