The MAX3232 Serial Module option provides a DB9 serial connection and a laser cut panel for the back of your Altair-Duino that mounts your DB9, power jack, and audio jack. Also included with this option is a spiral-bound, full color assembly manual. I strongly recommend selecting this option as it gives your Altair-Duino a nice professional look.

I’ve also added an option to include a micro SD card pre-loaded with disk images and tested. A few people have told me they’ve had difficulty finding an SD card that works. I’ve found that low-capacity cards work best, but they are becoming increasingly hard to find. These cards are 256MB – 1GB. Don’t worry about it being too small, I doubt there is 256MB of software for the Altair in existence! (An Altair 8″ floppy held 330k, and a 5.25″ “Mini-Disk” held 75k…)

This is a beginner to intermediate kit for people with experience soldering. It can be built in approximately 4-5 hours. Please read the Build Instructions to familiarize yourself with the construction of the kit, and don’t be afraid to email me with questions.

International Customers (outside the USA):
By default his kit includes a 9 volt power adapter made to connect to a Type A electrical socket (used in the USA, Canada, Mexico & Japan). You can choose to receive a 9 volt EU power adapter. If you want to use another power adapter, make sure it has a 5.5×2.1mm plug and provides 9v-12v at 1 amp. You can also power the Altair-Duino from a USB port.

*Please note: due to licensing issues the Bluetooth module will not connect to iOS devices (iPhone, iPad, iPod) but will connect to Mac and Windows computers.

    Very easy to build as long as you pay attention to the instructions and advice. Nothing beats the pictures to verify what you’re reading. That was a good tip to install the LEDs last using the panel to align. I suggest the same panel alignment technique with the switches before they are soldered or you will be unsoldering and moving them. I know, I broke one. The PCB design is very clean with minimal jumpers. Definitely fun to take control the computer using switches like the old days.

    I was able to quickly build the kit and had it working in a matter of a few hours. Well documented and well put together.

    Amazing kit. Had a bit of trouble with the header pins as outlined in the instructions, but i was able to overcome that with thinner rosin solder and a finer tip. The kit creator has great response time, is extremely helpful, and shipping time was rather fast!

    Easy to build kit, well documented apart from the audio connector is not mentioned !

    Led’s are too bright probably change the 150ohm resistor for 220 or 270 ?

    L1: It’s beautiful! Even the circuit board is nice to look at. It’s truly a work of art.
    L2: It’s fun to put together. It reminds me of the old Heathkit kits.
    L3: Some extra resistors, LEDs, and standoffs were provided.
    L4: It’s not powered by a Raspberry Pi, which would seem like cheating compared to an Arduino.

    D1: The LEDs are far too bright, especially in dim light.
    D2: Don’t run your fingers along the bamboo frame or you will get splinters.
    D3: You can’t easily access the SD card after completing the kit.
    D4: The 12V power supply seems unnecessary when it works with only 5V connected to the programming port. Can anyone suggest a panel mount micro-USB or USB-B female port for the round hole in the MAX3232 rear panel?

    The electronics are a piece of cake. It’s all nice, easy through-hole work with generous spacing. Just make sure you’ve got a Helping Hands or other means of holding the board at an angle, as you probably won’t want to let it rest directly on the components while you’re working.

    I had a little trouble with the mechanical aspects, e.g. getting all the screw holes and the front panel to line up, but I’m pretty awful at carpentry, so my results may not be typical. In the end, it turned out looking very good, even in spite of my fudging and trimming to get everything aligned.

    Took me about 4-5 hours in total, but everything worked first try, and I was able to boot up CP/M and play around with Ladder via Putty!

    Tip: if you’re installing the rear panel, solder the power and audio leads BEFORE mounting the panel in place.

    Building an Altair has been a life long dream of mine. As a collector of computer systems, the Altair has always eluded me. Thankfully, this kit was simple, lovingly crafted, well packaged, and a step by step instructions with photos are very logical. Chris Davis has not only provided the look and feel of an Altair, but has also included every scrap of software he could find. It’s very simple to mount and boot a disk from an impressive collection. This is the kind of the kit and software I’ve been looking for!
