AtomCNC V3

Yeah its been a while. I decided to upgrade my little cnc controller.. well. the PCB does the same thing but easier connectors and everything is replaceable. Its basically a carriage for PCBs. I Love thats its small. 99.7mm x 60.26mm AKA 3.93inch x 2.37inch. Holds 3 Axis and a cloned Y axis for my dual axis Y. Has simple connectors for my Limit Switches and Probe plus a RESET. Also has the Spindle and/or Laser port. So i can plug in a simple Spindle PCB for when i use it as a CNC and then Swap it for a Laser Controller when i use my Laser (2w diode) module.

The Controller is my tiny DipDuino Yep.. Made for it but can be used with other controllers. Just have to stick with the DIP form. Any how… take a peek 🙂

DipDuino in stock and new things to come.

DipDuino is in stock. Working on a new version of the breadboard buddy as well.

I’m working on some new PCB designs for breadboarding fun.

I’m thinking of also making some tools or programmers for AVR.. like my own AVR ISP programmer and a jtag programmer using the ftdi stuff. I’m not sure. Might consider creating a simple logic clone like those China made cypress semi ones.

Been lost in ideas and not sure where to start. The AVR ISP is actually almost here. J made the PCB and Oshpark sent them already. Should be here today or tomorrow.

I am missing one part I’ll have to order from digikey but … I have time so it’s ok.

DipDuino Sold Out, More to come

Ok DipDuino is sold out… But don’t worry more are on the way. New version 1.2 to be exact. Only difference is slightly longer but includes A6, A7 and smt option. So it will be a full breakout still at 0.3in dip style.

Here is a preview of whats to come. Those who own V1 will get a discount on V1.2 or be able to swap it (Minus Shipping) if they want the new V1.2.

6/28/2020 – V1.3R4 will be released soon. Price might drop as well.


Updated 5/30/2020 to include PWM Pins

Breadboard Buddy Uni C and Uni V4

The Uni C

Yes, finally here but JLCPCB Didnt V-Score my PCBs right. So i have to manually cut half of them. Any that comes out bad will be tossed.

Have a look at that beast. All the best features of the Breadboard Buddy Uni V3 but with a USB C Connector and 3A @ 3.3v supply, when fed from VIN, the USB C will supply up to 900mA. It still hasn’t been tested much.. Which is what I will be doing this weekend.

The Uni V4

3D Rendering

The V4 will be like the Uni C but with a Micro USB connector. Will allow up to 3A @ 3.3v output when fed from VIN or Wall USB Plug. PC USB will be limited as usual to 500mA.

8×8 Matrix Fun

Ive been playing with an 8×8 LED Matrix for a couple days and found it annoying to test designs and animations. So i created a nice C# application and Arduino Code to simplify this all. Coming soon! The application isnt 100% done but its fun to see it come to life.

This is a super simple program. You can shift and rotate led patterns. Also create multiple versions making animations simple. You can play the animation live or via the app only. You can name the entire code and each individual item. You can also Save, Open and Import designs to build bigger animations or fonts.

Here is a preview:

DipDuino

DipDuino is a Arduino in 0.3in DIP form. It runs the Atmega328P. Uses an onboard CP2104 to program itself and comes pre-programmed with Arduino Bootloader. Will act as a Arduino Pro or Pro Mini. Available in my Tindie Store.

The DipDuino is a FULL ARDUINO (Minus the A6 & A7 pins). Comes in 5v and 3.3v versions. There is a RGB LED onboard to show the status of Power and UART Transmissions. Green for Power and RED/Blue for Rx/Tx.

Comes with a Reset button on board as well and a LDO for 3.3v Versions. For 5v Versions power is taken straight from USB. Please be safe and careful not to short it.

Be aware its TINY!

Width is 0.37in [9.3mm] & 0.3in [7.62mm] pin width
Length is 1.82in [46.26mm] 

As most things in life it takes cost $ to test new revisions and upgrade things.. help me out with a Coffee at least 🙂 https://ko-fi.com/atomsofttech/

Breadboard Buddy Universal (V3)

Hey everyone. Got a new version of my BreadBoard Buddy out in the wild. I have only 1 left as they sold out quick. I’ll be making an order for new pcbs today. I’ll post a link also where to order later today. 1 lucky person is getting 2. They placed an order on tindie from me and I decided to give them the upgraded pcbs.

Here is info for it:

The newer version included 2 user LEDs and a universal layout for breadboards.

VIN Pin:
This pin connects to the regulator ONLY. It will NOT charge your battery. It will NOT touch USB Votlage. MAX VOLTAGE IS 6V on this pin.

LEDs:
L1 and L2 are both connected to ground with a 2K resistor. Simply supply a high voltage of about 2v-5v to turn them on.

User Button:
The Button can be Pulled High to 3.3v or 5V Using the solder jumper on bottom.

Lipo Charging/Power:
The battery charger can be set to either 100mA or 500mA charging current via a solder jumper on the bottom. When a battery is plugged in it will power the regulator on board. I used a BAT54C to share power with USB and VBAT so nothing blows up.

VCC Rails:
There are 2 rails. Left side and Right. Each rail can supply 3.3v or 5v to each side without affecting the other side. This is nice when you are working on a 5v / 3.3v system mixed.

LEDs are also using a higher resistor as they can be bright as heck. It’s nice to be able to see a LED on without blinding yourself. 🙂

Yes, for now the PCBs will be black.
