Just received our first prototype of a Nickel-metal Hydride battery charger with a USB plug. This board is made to charge from 1 to 6 cells in series and supports a thermister for sensing overheating batteries.

This circuit design is planned to be a part of a pen-like stylus with a camera and haptic feedback for blind people to feel visual art.

Just placed an order for a new prototype PCB (Printed Circuit Board) for makers. This one charges NiMH (Nickel-metal Hydride) rechargeable batteries with charging speed options, support for up to 6 cells, temperature sensor, and USB-C plug.

This is a step toward our first accessibility product for blind people to feel visual art through a haptic pen-like stylus interface.

I've been having fun with the artistic possibilities of #PCB design within #KiCad - I have seen some stunning bits of art in this medium ( #PCBArt)!

This #MechanicalKeyboard PCB art effort is much simpler, some line art imported as a silkscreen graphic, and then some simple texturing with the ground fill hatching.

(Why a tent? This is a small tented #ErgoMechKeyboard, meaning the PCB and keys are tilted relative to the table. The keyboard has 34 keys and the name Bivouac34 refers to a small wild camp)

This campaign will also unlock more PCB-style pins. Here are the designs so far, with a couple more yet to be revealed!

I've been pretty quiet lately! Conference season pretty much wrapped up after the 16th, and I've continued the headlong #KiCad / #PCB design streak I started a couple months ago.

Since fixing my @kicad setup ~3 weeks ago, I've done...
- 2 new #Charmware designs (will post tests soon!)
- Upgraded my #ESP8266 programmer planchette! (ordered yesterday)
- New modified Joule Thief board for the holidays! (ordered tonight)

...And various other things, like this #Hades gem concept :D

Happy place. <3

Being pretty much a beginner in PCB stuff, I can't tell whether this is good routing or absolutely horrible

But it should get the job done, right...? U1 is a MCP73831-2 charge IC

After a good five minutes trying to work out why these traces weren't using the net width I finally noticed this helpful readout at the bottom that tells you the width of the trace and the rule that set that width. Very nice touch.
