I knew I had time this weekend, but who knows what’s in store for next weekend. This would mean that I couldn’t work on it this weekend, but couldn’t start until next weekend. The reason I didn’t put them online, which would have saved me almost half, is that I’d be left with a delivery time of several days. The biggest expense was in the switches, and I admit I could have gotten them a lot cheaper. This is more than 3x as expensive as the cheapest number pads I could find at Coolblue and Mediamarkt, but of course you can’t program them yourself.

Because I already had the threaded inserts, the price I had to pay for the materials is €67.88. I have chosen to print my key caps, not only to cut costs, but also so that I can print new caps at any time if I want to switch functionality.

Multimeter (optional if you are a solder god who never makes a mistake.

4x M3 screws - €3.29 for a set of 30 including nuts.

Mounting cord - 0.4mm² / 21AWG - €2.60 for 5m (I took red and black for distinction).

24x Rectifier Diodes (Doesn’t matter which one, I used the 1N4004) - €5.00 for 100.

24x Cherry MX switches (I got the Blacks purely because my local electronics store had them in stock) - €1.45 x 24 = €34.80.

If you want to make one too, you’ll need the following. When I create 3d designs in Fusion 360, I often enter numbers via the number pad because it works faster for me, so it’s essential for me, but not essential enough to have it on my desk all the time. The Redox, like most split keyboards, has no number pad. A macro pad is a lot cheaper, less work, and with how I designed it, I can reuse a lot of the parts if it should fail.

There’s a good chance I’m taking too much on my fork with a full keyboard. The last time I successfully soldered was sometime in my youth when I took an electro-mechanics course. The thing is that making a whole keyboard right away is brave. My ultimate goal is to build a split keyboard, specifically the Redox v1.

In this post I want to explain how I created my new macro pad, but first maybe an explanation of why I created it. With my current schedule, that should probably be around 2023. I’ve only just started, so I can’t say much about it yet, maybe in a future post. Most importantly, after 3 years I left Sogeti, to continue as a Sr. It’s been a while since I’ve written a post, and a lot has happened in that time. Hey, liever de Nederlandse versie?
