PS2 Keyboard Input Now Working On The Altair
Log from Project Seven
Here it is! The MITS 88-2SIO dual serial port card has the ability to be configured, via a rabbit warren of jumper wires, for either TTL, RS-232, or Teletype mode. Likewise, the baud rate is also selected via jumpers, with separate jumpers for...

We Have X-Rays
Log from X-Ray CT scanners get new life
Watch as much as you want, but a few minutes into a 13-minute conditioning process, we got x-rays. And a much higher voltage than I was planning to reach for a while. 88 kV! 20 or so microamps! That's more than a watt! Also, I put my handy...

Expression evaluation
Log from One kilobyte Tiny BASIC for the 8080
When I first wrote the expression evaluator I used Dijkstra’s shunting yard algorithm for handling operator precedence and bracketed subexpressions. I changed approach later on when writing code for the RND, USR and ABS functions because I realised the...

Part 5: Sending for Assembly
Log from High Voltage Nixie Power Supply
The final version Before sending the board for assembly, I added some final touches in the form of a Revision C: This the final revision The changes compared to version B are very subtle, but you can note: Better positioning of the reference descriptions...

Bonus track
Log from Discrete component object recognition
Whilst thinking about the results obtained and licking my LDR inflicted wounds, I thought about a way to implement this object recognition system that would not involve fiddly hard to measure intensity levels. It occurred to me that I could change the...

Rule-based Generative Music Scripts
Log from Fluxamasynth Modules
There are many approaches to writing programs to generate music. For example, you can use Markov Chains, or you could hook up a Recurrent Neural Network to the Fluxamasynth Python module to compose new songs based on trained material. I'm less interested...

A little background
Log from Brushed DC Servo Drive
This project came to be when I became tired of searching for a commercial option for closed loop position control for a CNC machine I'm developing. The majority of the retrofit CNC drives I found were stepper motor drives, and altough many brushed or...

Battery Pack Construction
Log from Battery Supply for DSO138 portable Scope
Made a start on constructing the battery pack. Since I panned to use 2x 18650's in parallell I needed 2 of them that had voltages very close it each other, which meant going through my 18650 hoard:Managed to find 3 cells close, 2 of which were bang on...

random Q's
Log from Floppy-bird
Does it erase first, then write? Apparently not. I guess since it's binary, it needn't worry about 'ghosting' of old data. Then what's with the "erase" head[s]? Those erase (maybe 'crop'?) the edges of what was just-written. "tunnel erase". Apparently...

Initial design
Log from Universal Supercap Charger
After roughly a total of 30 hours of SPICE simulation, I have managed to create a decent design for charging a 120F supercapacitor at 5A to roughly 2.5V in under a minute. There were a number of problems such as inrush current, various spikes of more...

"Why worry? Each of us is wearing an unlicensed nuclear accelerator on his back." -- or, on The Independent Design and Production of a Functional-In-Universe Proton Pack
Log from "Ghostbusters" Indie Proton Pack Build
Right, so a Proton Pack functions, basically, by generating a highly-energetic, directional stream of intense, charged alpha radiation -- i.e., high-energy protons at high speed.If a cyclotron isn't a reasonable possibility, well, what is?Let's break...

Adding power storage
Log from Low cost solar panel solution (MPPT + sun tracker)
What would be a solar system without a battery ? A power bank is especially helpful if you hope to use solar energy when there’s no sun: illuminating a campsite at nighttime, charging your phone when raining, or keeping your laptop running on a cloudy...

Snail Mail Notifier by Solenoid
Log from Me building projects from hackaday.io
#Snail Mail Notifier by @SolenoidThis is a long time shelfie, because I never had the 0805/0603 parts - and I'm not done yet. I'm just now able to use and program the receiver as a digispark. Rewarding hacking around though. I hope I can get some decoding...

Radioactive sources
Log from Open source expansion cloud chamber
1. UraniniteTry to buy Uraninite (formerly pitchblende) at a mineral show. I bought some pieces of Uraninite from the famous formerly Russian uranium mine of Hartenstein, Saxony, Germany, at an internet mineral show. Uraninite contains up to 88% uranium....

Supporting X-Axis Expansion
Log from Monoprice Select Mini Electro-Mechanical Upgrades
Balance. Why is it needed? One end of the X-axis is unsupported. If you extend this out, there should be enough force to have thins begin to bend. I'm not an mechanical engineer so I cannot calculate how much the 3 Z-Axis rods will bend when you're mid...
